Frequently Asked Questions - F 125 BARTSCHER

How to start the F 125 ice machine?

After properly installing the appliance and connecting it to the electrical and water supply, open the water tap and turn it on. The first green LED lights up. Important: each time the power is turned on after a stop, the red LED flashes for 3 minutes, then the appliance starts automatically with the gearmotor followed by the compressor after 5 seconds.

What to do if the yellow 'water shortage' LED lights up?

Check the water supply (tap open, sufficient pressure). If the water is too soft (conductivity < 30 µS), install a mineral salt dispenser. Clean the water level sensors if they are scaled. If the problem persists, consult the manual for sensor replacement.

How to clean the hydraulic circuit?

Turn off the appliance, close the shut-off valve. Remove the top panel, disconnect the hose from the tank to the freezer. Slowly pour a descaling agent into the float tank, then turn it back on. Let the machine produce ice with the product, then rinse with clean water until the ice is clean. Disinfect the reservoir with a bactericidal solution.

How to adjust the water level in the evaporator?

The correct water level is 25 mm below the ice discharge opening. To increase it, unscrew the screw of the tank support and raise the tank. To lower it, lower the tank. Reverse the action. Retighten the screw in the corresponding hole.

What does a steady red LED mean?

A steady red LED indicates an alarm for excessive condensation temperature (dirty condenser, fan motor failure, ambient temperature too high) or for ambient temperature below 1°C. The appliance stops and restarts after a maximum of one hour. If the anomaly repeats 3 times in 3 hours, the stop is permanent. Eliminate the cause and reset by unplugging and plugging the appliance back in.

How to replace the auger seal?

Remove the front panel and the discharge chute. Unscrew the 2 screws of the support strip of the chute. Pull the auger/crusher assembly upwards. Replace the brass rotating ring, the complete seal, and the bearings. Use the provided spare part kit. Lubricate the bearings with water-resistant food-grade grease.

What is the cleaning frequency for the condenser?

The condenser must be cleaned at least twice a year (more often in a dusty environment). Use a vacuum cleaner and a non-metallic brush. Be careful not to damage the temperature sensors. A dirty condenser causes a pressure increase and an alarm.

Can I use very soft (demineralized) water?

No, because water with a conductivity below 30 µS does not allow the low-voltage current to pass between the water level sensors, which prevents the correct operation of the appliance. Install a mineral salt dispenser or use water with adequate mineralization.

How to test the optical ice level sensor?

Place ice between the two infrared sensors located in the discharge chute. The yellow 'bin full' LED should flash and then stay on steady after 6 seconds. The appliance stops. Remove the ice, the light beam is restored, and the machine restarts after a 6-second delay.

What to do in case of excessive noise or squeaking?

This may be due to lime scale deposits on the internal surfaces of the freezer or the auger. Remove the auger and clean the walls with emery cloth by rubbing vertically. Also check the freezer and gearmotor bearings, and replace them if worn. Ensure that lubrication is correct.

GENERAL INFORMATION AND INSTALLATION

A INTRODUCTION

the step-by-step procedures for the installation, start- up and operation, maintenance and cleaning for the F80 - F125 Modular Icemakers.

The Electronic Flakers and Superflakers are quality designed, engineered and manufactured. Their ice making systems are thoroughly tested providing the utmost in flexibility to fit the needs of a particular user.

B. UNPACKING AND INSPECTION Icemaker

1 Call you rauthorizedl Distributor or Dealer for proper installation.
2 Visually inspect the exterior of the packing and skid. Any severe damage noted should be reported to the delivering carrier and a concealed damage claimformfilled in subject to inspection of the contents with the carrier's representative present.
3 a) Cut and remove the plastic strip securing the carton box to the skid.
b) Cut open the top of the carton and remove the polystyre protection sheet.

NOTE. To retain the safety and performance built into this icemaker, it is important that installation and maintenance be conducted in the manner outlined in this manual.

c) Pull out the polystyre posts from the corners and then remove the carton.
d) Lift the whole carton and pull it out from the device.

4 Remove top and sides panels of the unit and inspect for any concealed damage. Notify carrier of your claim for the concealed damage as stated in step 2 above.
5 Remove all internal support packing and masking tape.
6 Check that refrigerant lines do not rub against or touch other lines or surfaces, and that the fan blades move freely.
7 Check that the compressor fits snugly onto all its mounting pads.
8 See data plate on the rear side of the unit and check that local main voltage corresponds with the voltage specified on it.

C. LOCATION AND LEVELLING

WARNING. This Modular Flaker and Superflaker is designed for indoor installation only. Extended periods of operation at temperature exceeding the following limitations will constitute misuse under the terms of the Manufacturer's Limited Warranty resulting in LOSS of warranty coverage.

1 Position the storage bin in the selected permanent location. Criteria for selection of location include:

a) Minimum room temperature 10^ (50^) and maximum room temperature 40^ (100^) .
b) Water inlet temperatures: minimum 5^ (40^) and maximum 35^ (90^) .
c) Well ventilated location for air cooled models (clean the air cooled condenser at frequent intervals).
d) Service access: adequate space must be left for all service connections through the rear of the ice maker.

A minimum clearance of 15cm (6") must be left at the sides of the unit for routing cooling air drawn into and exhausted out of the compartment to maintain proper condensing operation of air cooled models.

2 Level the Storage Bin Assy in both the left to right and front to rear directions by means of the adjustable legs.

NOTE: This ice flake maker contains sensitive and highly precise parts. Knocks and heavy blows must therefore be avoided.

D. ELECTRICAL CONNECTIONS

See data plate for current requirements to determine wire size to be used for electrical connections. All icemakers require a solid earth wire.

All ice machines are supplied from the factory completely pre-wired and require only electrical power connections to the wire cord provided at the rear of the unit.

Make sure that the ice machine is connected to its own circuit and individually fused (see data plate for fuse size).

The maximum allowable voltage variation should not exceed -10% and +10% of the data plate rating. Low voltage can cause faulty functioning and may be responsible for serious damage to the overload switch and motor windings.

NOTE. All external wiring should conform to national, state and local standards and regulations.

Check voltage on the line and the ice maker's data plate before connecting the unit.

E. WATER SUPPLY AND DRAIN CONNECTIONS

When choosing the water supply for the ice flaker consideration should be given to:

a) Length of run
b) Water clarity and purity
c) Adequate water supply pressure

Since water is the most important single ingredient in producing ice you cannot emphasize too much the three items listed above.

Low water pressure, below 1 bar may cause malfunction of the ice maker unit.

Water containing excessive minerals will tend to produce scale build-up on the interior parts of the water system while too soft water (with too lo contents of mineral salts), will produce a very hard flaker ice.

ATTENTION. The use of fully hardened water (without or nearly without mineral salts) with electric cable capability of under 30~ S blocks the flow of low voltage electricity between the lowest sensors in the swimming pool and therefore causes the device to be switched off or to stop working

Dark chlorinated or iron-containing water can be improved through the active carbon filter

If water contains a high level of impurities, it is advisable to consider the installation of an appropriate water filter or conditioner.

WATER SUPPLY

Connect the 3/4'' GAS male of the water inlet fitting, using the foodgradeflexible hosesupplied to the coldwater supply linewith regular plumbing fitting and a shut-off valve installed in an accessible position between the water supply line and the unit.

If water contains a high level of impurities, it is advisable to consider the installation of an appropriate water filter or conditioner.

WATER SUPPLY - WATER COOLED MODELS

The water cooled versions of Ice Makers require two separate inletwater supplies, one for the water making the flaker ice and the other for the water cooled condenser.

Connect the 3/4'' GAS male fitting of the water inlet, using the flexible hose supplied to the cold water supply linewith regular plumbing fitting and a shut-off valve installed in an accessible position between the water supply line and the unit.

WATER DRAIN

The recommended drain tube is a plastic or flexible hose with 18mm(3/4^ ) I.D. which runs to an open trapped and vented drain. When the drain is a long run, allow 3 cm pitch per meter (1/4" pitch per foot). Install a vertical open vent on drain line high point at the unit drain connection to ensure good draining.

Theidealdrainreceptacleisatrappedandvented floor drain.

WATER DRAIN - WATER COOLED MODELS

Connect the 3/4'' GAS male fitting of the condenser water drain, utilizing a second flexible hose to the open trapped and vented drain.

This additional drain linemust not interconnect to any other of the units drains.

NOTE. The water supply and the water drain must be installed to conform with the local code. In some case a licensed plumber and/or a plumbing permit is required.

F. FINAL CHECK LIST

1 Is the unit in a room where ambient temperatures are within a minimum of 10^ (50^) even in winter months?

2 Is there at least a 15 cm (6") clearance around the unit for proper air circulation?

3 Is the unit level? (IMPORTANT)

4 Have all the electrical and plumbing connections been made, and is the water supply shut-off valve open?
5 Has the voltage been tested and checked against the data plate rating?
6 Has the water supply pressure been checked to ensure a water pressure of at least 1 bar (14 psi). been checked to ensure that the compressor is snugly fitted onto the mounting pads?
8 Check all refrigerant lines and conduit lines to guard against vibrations and possible failure.

9 Have the bin liner and cabinet been wiped clean?
10 Has the owner/user been given the User Manual and been instructed on the importance of periodic maintenance checks?
11 Has the Manufacturer's registration card been filled in properly? Check for correct model and serial number against the serial plate and mail the registration card to the factory.
12 Has the owner been given the name and the phone number of the authorized Service Agency serving him?

WARNING. This icemaker is not designed for outdoor installation and will not function in ambient temperatures below 10^ (50^) or above 40^ (100^) . This icemaker will malfunction with water temperatures below 5^ (40^) or above 35^ (90^) .

OPERATING INSTRUCTIONS

STARTUP

After having correctly installed the ice maker and completed t he plumbing and electrical connections, perform the following "Start-up" procedure.

A. Open the water supply line shutoff valve and put the unit under electrical power by moving the main switch, on the power supply line, to the ON position.

The first LED - GREEN - will glow to signal that unit is under power.

NOTE. Every time the unit is put under power, after being kept for sometime in shut-off conditions (electrically disconnected) the RED LED will blink for 3 minutes (60^ on MF 66 only) after which the unit will start up with the immediate operation of the gear motor assembly and, after few seconds, of the compressor (Fig.1).

B. Elapsed the stand by period the unit starts operating with the activation in sequence of the following assemblies:

GEAR MOTOR/S

COMPRESSOR

FAN MOTOR/S (if unit is an air cooled version) kept under control by the condenser temperature sensor which has its probe within the condenser fins (Fig.2).

C. After 2 or 3 minutes from the compressor start up, observe that flaker ice begins dropping off the ice spout to fall through the ice chute into the storage bin.

NOTE. The first ice bits that drop into the ice storage bin are not so hard as the evaporating temperature has not yet reached the correct operating value. It is necessary to allow the ice - just made - to cure itself and wait for about ten minutes for the evaporating temperature to reach the correct value so to make more hard bits of ice.

FIG.1

FIG.2

FIG.3

NOTE. If, after ten minutes from the compressor start-up, the evaporating temperature has not dropped down to a value lower than -f C (30 F) the evaporating temperature sensor detects such an abnormal situation and stops consequently the unit operation (first the compressor and 3' later the gear reducer).

In this circumstance, the 5th warning YELLOW LED will blink.

The machine will remain in OFF mode for one hour then it will restart automatically. In case the unit trips OFF again in alarm for 3 times in 3 hours, the machine SHUTS OFF DEFINITIVELY.

After having diagnosed and eliminated the cause of the too hi evaporating temperature (insufficient refrigerant in the system or compressor not running) it is necessary to unplug and plug in again to restart machine. The unit, before resuming the normal operation, will go through the usual 3 minutes STAND-BY period.

the

D. Remove front service panel and, if necessary, install the refrigerant service gauges on the corresponding service valves to check both the HI and LO refrigerant pressures.

NOTE. On air cooled models, the condenser temperature sensor, which is located within the condenser fins, keeps the head (condensing) pressure between preset values.

In the event of condenser clogged - such to prevent the proper flow of the cooling air-or, in case the fan motor is out of operation, the condenser temperature rises and when it reaches 70^ (160^) for air cooled version and 60^ (140^) - for water cooled version the condenser temperature sensor shuts-off the ice maker (first the compressor and 3^ later the gear reducer) with the consequent light-up of the RED WARNING LIGHT(Fig.3).

The machine will remain in OFF mode for one hour then it will restart automatically. In case the unit trips OFF again in alarm for 3 times in 3 hours, the machine SHUTS OFF DEFINITIVELY.

After having diagnosed the reason of the temperature rise and removed its cause, it is necessary to proceed as per the previous "NOTE" to start up again the operation of the ice maker.

E. Check for the correct CUT-OUT and CUT-IN of the water levelsensor by first shutting closed the water shutoff valve on the water supply line.

FIG. 4

This will cause a gradual decrease of the water level in the float reservoir and as soon as the level gets below the two vertical metal pins, the flaker stops to operate (compressor first and 3' later the gear reducer) and the YELLOW warning LED will glow to signal the shortage of water (Fig.4)

NOTE. The water level sensor detects the presence of water in the float reservoir and confirms it to the micro processor by maintaining a low voltage current flow between the two metal pins using the water as conductor.

WARNING. The use of de-mineralized water (water with no salt content) having an electrical conductivity lower than 30 S , will cause break with the consequent CUT-OUT of the flaker and the glowing of the YELLOW LED of water shortage, even with water in the reservoir.

Opening the water supply line shutoff valve to fill up again the float reservoir, the YELLOW LED goes off while the RED LED starts blinking.

After 3 minutes the unit resumes its total operation with the immediate start-up of the gear motor and, few seconds later, of the compressor.

F. Check for the correct operation of the electronic eye (one per each ice chute on mode MF 66) of the optical ice level control, by closing the bottom opening of the vertical ice chute. Wait the built up of the ice into the ice chute till cuts the light beam of the sensing "eyes". This interruption will cause an immediate blinking of the Bin Full YELLOW LED located on the fro of the P.C. Board and after about 6 secor causes the shutoff of the unit (compressor first and 3^ later the gear reducer) with the simultaneous lighting (steady) of the Same LED signalling the full bin situation (Fig.5).

Discharge the ice from the ice chute so to resur the light beam previously interrupted (YELLOW LED blinking fast) and after about 6 seconds the flaker will re-start -through the 3 minutes STANDBY period-with the extinguishing of the YELLOW LED.

NOTE. The ICE LEVEL CONTROL (INFRARED SYSTEM) is independent of the temperature however, the reliability of its detection can be affected by external light radiations or by any sort of dirt and scale sediment which may deposit directly on the light source and on the receiver. To prevent any possible ice maker malfunction, it is advisable to locate the unit where it can't be reached by any direct light beam or light radiation and to follow the instructions for the periodical cleaning of the light sensor elements as detailed in the MAINTENANCE AND CLEANING PROCEDURES.

NOTE. In the front of the PC Board is located a small I/R Trimmer directly connected with the optical Ice level control. By means of its screw it is possible to modify the signal received from the Ice Level control so to overcame some problem caused by dirt and/or low power supply. When adjusted it is very important to check for its correct operation using ice (NOT HAND) to break the Infrared Beam. In case the machine doesn't stop it means that the new setting is too much powerful and need to be reduced always by means of the I/R Trimmer.

M. If previously installed, remove the refrigerant service gauges and re-fit the unit service panels previously removed.

N. Instruct the owner/user on the general operation of the ice machine and about the cleaning and care it requires.

The water enter in the machine through the water inlet fitting which incorporates a strainer - located at the rear side of the cabinet - then it goes to the water reservoir flowing through a float valve.

NOTE. The presence of the water in the float reservoir is detected by a system of two sensors which operates in conjunction with the P.C. Board. The two sensors use the water as a conductor to maintain a low voltage current flow between them. In case the water used is very soft (de-mineralized) or the float reservoir gets empty the current flow between the sensors become so weak or is no longer maintained that, as consequence, the P.C. Board shutoff the flaker operation with the simultaneous glowing of the YELLOW LED signalling "Shortage of water".

The float reservoir is positioned at the side of the freezing at such an height to be able to maintain a constant water level. The water flows from the reservoir into the bottom inlet of the freezer to surround the stainless steel auger which is vertically fitted in the center of the freezer.

In the freezer the incoming water gets chilled into soft (slush) ice which is moved upward by the rotating action of the auger. The auger rotates counterclockwise within the freezer powered by a direct drive gear motor and carries the ice upward along the refrigerated freezer innerwalls andbydoingso theice gets progressively thicker and harder.

The ice, being costantly lifted up, meet the teeth of the ice breakerwhich is fitted on the top end of the auger,where it gets compacted, cracked and forced to change from vertical into horizontal motion to be discharged out, through the ice spout and chute, into the storage bin.

By running the ice maker, i.e. by putting the unit under power, starts the automatic and continuous icemaking process which would not stop until the ice storage bin gets filled-up to the level of the control "eyes" located on the ice chute. As the ice level raises to interrupt the light beam running between the two infrared leds, the unit stops after six seconds (compressor first and 3' later the gear reducer), with the simultaneous glowing of the YELLOW LED signalling the "Full Bin" situation.

NOTE. The interruption of the light beam between the two light sensors is immediately signalled by the blinking of the BIN FULL YELLOW LED located on the front of the P.C. Board.

After about 6" of steady interruption of the light beam the unit stops and the "Full Bin" YELLOW LED glows steady.

The six seconds of delay prevent the unit from stopping for any undue reason like the momentarily interruption of the light beam caused by the flakes that slides along the ice spout before dropping into the bin.

As some ice gets scooped out from the storage bin, the light beam between the two sensors resumes (fast blinking of YELLOW LED) and six seconds later the ice machine restarts the ice making process - going always through the 3' stand by - and the YELLOW LED goes off.

REFRIGERANT CIRCUIT

The hot gas refrigerant discharged out from the compressor reaches the condenser where, being cooled down, condenses into liquid.
Flowing into the liquid line it passes through the drier filter, then it goes all theway throughtca-pillary tubewhere it looses some of its pressure so that its pressure and temperature are lowered. Next, the refrigerant enters into the evaporator coil wrapped around the freezer inner tube.
The water being constantly fed at the interior of thefreezer inner tube,exchange heat with the refrigerant circulating into the evaporator coil, this cause the refrigerant to boil-off and evaporate, there by it changes from liquid into vapor.
The vapor refrigerant then passes through the

suction accumulator and through the suction line where the refrigerant exchanges heat with the one flowing into the capillary tube (warmer) before beingsucked into the compressor to be recirculated.

The refrigerant head pressure is kept between two pre-set values (8÷9 bar - 110÷125 psig on F120) by the condenser temperature sensor which has its probe located within the condenser fins - in air cooled versions.

This condenser temperature sensor, when senses a rising of the condenser temperature beyond the pre-fixedlimit, changes its electrical resistance and send a low voltage power flow to the MICROPROCESSOR of the P.C. Board which energizes, through a TRIAC, the Fan Motor in ON-OFF mode.

On the water cooled versions, the refrigerant head pressure is kept at the constant value of 8.5 bar (120 psig) on F120 by themetered amount of water passing through the condenser which is regulated by the action of the Water Regulating Valve that has its capillary tube connected to the liquid refrigerant line. As pressure increases, the water regulating valve opens to increase the flow of cooling water to the condenser.

NOTE. In case the condenser temperature probe senses that the condenser temperature has risen to 70^ on air cooled version - or 60^ Conwater cooled version - for one of the following abnormal reasons:

CLOGGED CONDenser (Air cooled version) INSUFFICIENT FLOW OF COOLING

WATER (Water cooled version)

FAN MOTOR OUT OF OPERATION (Air cooled version)

AMBIENT TEMPERATURE HIGHER THEN 43^ (110°F)

it causes the total and immediate SHUT-OFF of the machine (compressor first and gear motor 3' later) in order to prevent the unit from operating in abnormal and dangerous conditions.

When the ice maker stops on account of this protective device, there is a simultaneous glowing of the RED LED, warning the user of the Hi Temperature situation.

The machine will remain in OFF mode for one hour then it will restart automatically.

In case the unit trips OFF again in alarm for 3 times in 3 hours, the machine SHUTS OFF DEFINITIVELY.

After having eliminated the source of the excessive condenser temperature, to restart the ice-machine it is necessary to unplug and plug in again.

The RED LED starts blinking and three minutes later the flaker unit resume its normal operating mode. The condenser temperature sensor has a further safety function which consist in preventing the unit from operating in Lo-ambient conditions i.e. when the condenser temperature - equivalent to the ambient temperature - is lower then 1^ 34^ (Fig.6).

As soon as the ambient temperature rises up to 5^ the P.C. Board restarts automatically the machine on the three minutes starting time.

The refrigerant suction or Lo-pressure sets - in normal ambient conditions - on the value of 0.5 bar (7 psig) on F120 after few minutes from the unit start-up.

This value can vary of 0.1 or 0.2 bar (1.5÷3 psig) in relation to the water temperture variations influencing the freezer cylinder.

NOTE. If, after ten minutes from the unit start up, no ice is made and the evaporating temperature detected by the evaporator sensor results to be higher than -1^ 30^ the ice maker stops (compressor first and gear motor 3 later) and the 5th WARNING YELLOW LED blinks.

The machine will remain in OFF mode for one hour then it will restart automatically. In case the unit trips OFF again in alarm for 3 times in 3 hours, themachine SHUTSOFF DEFINITIVELY.

MECHANICAL SYSTEM

The mechanical system of the Flaker machines consists basically of a gear motor assembly which drives, through a ratched coupling, a worn shaft or auger placed on its vertical axis within the freezing cylinder.

The gear motor is made of a single phase electric motor with a permanent capacitor. This motor is directly fitted in the gear case through which it drives - in counter clockwise rotation at a speed of 9.5 r.p.m. - the freezer auger being linked to it by the ratched coupling.

Too low ambient and water temperature (well below the limitations of respectively 10^ and 5^ - 50^ and 40^ ) or frequent interruptions of the water supply to the freezing cylinder (clogging of the water hose connecting the float reservoir to the water inlet at the bottom of the freezer) may cause the ice to get too hard and compact loosing fluidity and thereby seizing the auger.

This situation will put under excessive strain and load the entire drive system and freezer bearings.

NOTE. Before charging the refrigerant system always check the type of refrigerant and quantity as specified on the individual ice machine dataplate. The refrigerant charges indicated are relatives to averages operating conditions.

COMPONENTS DESCRIPTION

A Evaporator temperature sensor

The evaporator sensor probe is inserted into its tube well, which is welded on the evaporator outlet line, it detects the temperature of the refrigerant on the way out from the evaporator and signals it by suppling a low voltage current flow to the P.C. Board.

According to the current received, the microprocessor let the ice maker to continue its operations or not. In case the evaporating temperature, after 10 minutes from the unit start-up, does not go below -1^ (30°F) the evaporator sensor signals to stop immediately the unit operation, with the blinking of the 5th Warning YELLOW LED.

NOTE. Themachinewill remainINOFFmode for one hour then it will restart automatically. In case the unit trips OFF again in alarm for 3 times in 3 hours, themachine SHUTSOFF DEFINITIVELY.

To restart the unit after the shutoff caused by the hi evaporating temperature, it is necessary to switch OFF and ON the power line main disconnect Switch.

B Water level sensor

This sensor consists of two small stainless steel rods vertically fitted on the inner face of the reservoir cover and electrically connected to the low voltage circuit of the P.C. Board. When the cover of the reservoir is positioned in its place the tips of both the rods dip into the reservoir water transmitting a low power current throu the same.

NOTE. In the event of shortage of water in the reservoir or, in case the water used is too soft (de-mineralized) to cause greater resistance to the current flow (electrical conductivity lower than 30 S ) this sensor system causes the shutoff of the machine, to protect it from running without water or with an inadequate water quality. In this situation the YELLOW LED will glow to warn of the machine shutoff and the reason why.

C Condenser temperature sensor

The condenser temperature sensor probe, located within the condenser fins (air cooled version) or in contact with the tube coil (water cooled version) detects the condenser temperature variations and signals them by supplying current, at low voltage, to the P.C. BOARD.

In case thecondenser temperaturesensordetects a temperature at the condenser lower than +3^ (37^) that means ambient temperature too low for the correct unit operation, the sensor signals to the P.C. BOARD to do not start up the unit till the ambient temperature rises to 10^ .

In the air cooled versions, in relation to the different current transmitted, the micro processor of the P.C. BOARD supplies, through a TRIAC, the power at high voltage to the fan motor.

In the event the condenser temperature rises and reaches 60^ or 70^ according to the setting of DIP SWITCH number 8 the current arriving to the micro processor is such to cause an immediate and total stop of the machine operation.

NOTE. The machine will remain in OFF mode for one hour then it will restart automatically. In case the unit trips OFF again in alarm for 3 times in 3 hours, themachine SHUTSOFF DEFI-NITIVELY.

To restart the unit after the shutoff caused by the hi condenser temperature, it is necessary to switch OFF and ON the power line main disconnect Switch.

D Electromagnetic sensor

This safety device is housed on top of the Drive Motor and detects - based on Hall Effect principle - the rotating speed and rotating direction of the drive Motor.

Should the rotating speed drop below 1300 r.p.m. the magnitude measured by this device is such to signal to the microprocessor to stop the unit and light-up the YELLOW LED. The same reaction occurs when the drive motor will tend to rotate inthewrongdirection(counterclockwise) or when it doesn't rotate at all.

NOTE. The machine will remain in OFF mode for one hour then it will restart automatically. In case the unit trips OFF again in alarm for 3 times in 3 hours, the machine SHUTS OFF DEFINITIVELY. To restart the unit after the shutoff caused by this safety device, it is necessary first to eliminate the cause that has generated the intervention of the device and then switch OFF and ON the power line main disconnect switch.

E Optical ice level control

The electronic optical ice level control, located into the ice chute has the function to stop the operation of the ice machine when the light beam between the light source and the receiver gets interrupted by the flake ice which accumulates in the chute.

When the light beam is interrupted the Bin Full YELLOW LED located in the front of the P.C. BOARD blinks; in case the light beam gets interrupted for as longer as 6 seconds, the ice machine stops with the glowing-up of the 2nd YELLOWLEDto monitor the full ice binsituation. The 6 seconds of delay prevents that any minimum interruption of the light beam due to the regular ice chuting through the ice chute may stop the operation of the unit.

As soon as the ice is scooped out (with the resumption of the light beam between the two infrared sensor of ice level control - YELLOW LED blinks fast) 6 seconds later the ice machine resumes its operation with the simultaneous extinguishing the 2nd YELLOW LED.

F P.C. BOARD (Data processor)

The P.C. BOARD, fitted in its plastic box located in the front of the unit, consists of two separated printed circuits one at high and the other at low voltage and protected by fuses. Also it consists of five aligned LEDs monitoring the operation of the machine of three jumpers and of input terminals for the leads of the sensor probes as well as input and output terminals for the leads of the ice maker electrical wires. The P.C. BOARD is the brain of the system and it elaborates, through its micro processor, the signals received from the sensors in order to control the operation of the different electrical components of the ice maker (compressor, gear motor, etc.). The five LEDs, placed in a row in the front of the P.C. BOARD, monitor the following situations:

H Float reservoir

The float reservoir consists of a plastic water pan on which is fitted a float valve with its setting screw. The float valve modulate the incoming water flow to maintain a constant water level in the reservoir, level that corresponds to the one in the freezing cylinder to ensure proper ice formation and fluidity.

On the inner side of the reservoir cover are fitted the twowater level sensor pinswhich detects the presence or the shortageof water inthereservoir.

NOTE. It is very important to make sure of the correct fitting of the cover on the reservoir in order to enable the sensor to efficiently control the water situation avoiding undue shutoff interventions.

1 Freezing cylinder or evaporator

The freezing cylinder ismade of a stainless steel vertical tube onwhich exterior iswrapped around the cooling coil with the evaporating chamber and in its interior is located the auger which rotates on its vertical axis and it is maintained aligned by the top and bottom bearings. A water seal system is located in the bottom part of the freezer while at the top end is fitted the ice breaker.

The water constantly flowing into the cylinder bottompart, freezes into ice when in contact with the cylinder inner walls. The ice is then lifted up by the rotating auger and compacted and forced out by the ice breaker.

J Eisbrecher

The gearmotor ismade of a single phase electric motor with permanent capacitor directly fitted on a gear box.

The drive motor rotor is kept aligned on its vertical axis by two ball bearings permanently lubricated. The gear case contains a train of three spur gears with the first one in fiber to limit the noise level. All the three gears are encased in case roller bearings and are covered by lubricant grease (MOBILPLEX IP 44).

Two seal rings, one fitted on the rotor shaft and the other on the output shaft keep the gear case sealed.

The interior can be inspected and serviced by unbolting the two halves of the aluminium gear case housing.

L Fan motor (Air cooled version)

The fanmotor is controlled through the TRIAC of the P.C. BOARD by the condenser temperature sensor. Normally it operates to draw cooling air through the condenser fins.

In cold ambient situation, the fan motor can run at intermittance as the condenser pressure must be kept between two corresponding head pressure values.

M Water regulating valve

This valve controls the head pressure in the refrigerant system by regulating the flow of water going to the condenser.

As pressure increases, the water regulating valve opens to increase the flow of cooling water.

N Compressor

The hermetic compressor is the heart of the refrigerant system and it is used to circulate and retrieve the refrigerant throughout the entire system.

It compresses the lowpressure refrigerant vapor causing its temperature to rise and become high pressurehotvaporwhich isthenreleased through the discharge valve.

ADJUSTMENT, REMOVAL AND REPLACEMENT PROCEDURES

NOTE. Read the instructions throughly before performing any of the following adjustment or removal and replacement procedure.

The periods and the procedures for maintenance and cleaning are given as guides and are not to be construed as absolute or invariable. Cleaning, especially, will vary depending upon local water and ambient conditions and the ice volume produced; and, each icemaker must be maintained individually, in accordance with its particular location requirements.

B ICEMAKER

The following maintenance should be scheduled at least two times per year on these icemakers.

1 Check and clean the water line strainer.
2 Remove the cover from the float reservoir - care to do not damage the two water sensors - and depress the float to make sure that a full stream of water enters into the reservoir. If not gently remove the float valve from its reservoir bracket than clean the hole of the nozzle.
3 Check that the icemaker is levelled in side to side and in front to rear directions.
4 Check that the water level in the water reservoir is below the overflow but high enough that it does not run out of the spout opening.
5 Clean the water system, water reservoir and the interior of freezing cylinder using a solution of cleaner.

Refer to procedure C cleaning instructions and after cleaning will indicate frequency and procedure to be followed in local areas.

NOTE. Cleaning requirements vary according to the local water conditions and individual user operation.

6 If required, polish the two sensor rods secured to the float reservoir cover, heavy scale sediment on them can be removed with the help of a bit of cleaner.
7 With the ice machine and fan motor OFF on air cooled models, clean condenser using vacuum cleaner, whisk broom or non metallic brush taking care to do not damage the condenser/ambient temperature sensor.
8 Check for water leaks and tighten drain line connections. Pour water down bin drain line to be sure that drain line is open and clear.
9 Check the ice level control sensor to test shut-off. Close the bottom of the ice chute and wait till it is completely full of ice so to cut off the light beam for at least 6 seconds. This should cause the immediate blinking of the Bin Full YELLOW LED located in the front of P.C. Board and, 6 seconds later, the total stopping of the ice maker with the simultaneous light up of the same LED (steady).

Within few seconds from the removal of the ice between the sensor lights the ice maker resume its operation.

NOTE: The ice level control uses devices that sense light, therefore they must be kept clean enough so they can "see".

Everythree-monthsremovetheopticalsystem then clean/wipe the sensing "eyes" with a clean soft cloth.

10Check for refrigerant leaks and for proper frost line, which should frost as far as approx. 20~cm (8^ ) from the compressor.
11 When doubtful about refrigerant charge, install refrigerant gauges on corresponding service valvesandcheckforcorrect refrigerantpressures.
12Check that fan blades move freely and are not touching any surfaces.

13 Remove the retaining ring and the hook and cap from the top of the freezer assembly then inspect the top bearing, wipe clean of all grease and apply a coating of food grade water proof grease.

NOTE. It is recommended to use only food grade and waterproof grease to lubricate the freezer top bearing.

14Check the quality of ice.

NOTE. It is not abnormal for some water to emerge from the ice spout with the flaker ice.

Ice flakes should be wet when formed, but will cure rapidly to normal hardness in the bin.

C. CLEANING INSTRUCTIONS OF WATER SYSTEM

1 Switch OFF the Master disconnect switch on the power line.
2 Remove all ice stored in the bin to prevent it from getting contaminated with the cleaning solution.
3. Shut close the water shutoff valve on water line.
4 Remove the top panels to gain access to the water reservoir.
5. Remove the float reservoir cover and with a piece of copper wire short the two metal pins of the water level sensor.

NOTE. Put one or both of the water sensor on the casing of the equipment, because in this way through the condenser sensor voltage will be transferred and the equipment will be switched off through that due to high temperature.

6 Place a water pan under the freezer water inlet port, disconnect the water hose from this port and allow the water from the freezer to flow into the pan. Then refit the water hose to the freezer water inlet port.
7 Prepare the cleaning solution in a plastic container.r
8 Pour the cleaning solution into the water reservoir.
9 Wait till the machine starts to discharge ice, then continue to slowly pour the cleaning solution into the water reservoir taking care to maintain the level just below the overflow.

NOTE. The ice produced with the decalcification solution is yellowish and smooth. In this phase, there are loud noises from the freezer due to the rubbing between the rising ice and the evaporator walls. In this case, it is recommended that the equipment should be switched off for some minutes, so that the decalcification solution in the freezer can be released.

10 When all the cleaning solution has been used up, open the water shutoff valve to allow new fresh water to flow into the reservoir. Let the unit to continue to run until the ice resumes the normal colour and hardness.
11Stop the icemaker and pour warmwater on the ice deposited into the storage bin to melt it up.

ATTENTION use ice produced with the cleaner solution. Be sure none remains in the bin.

12Left the unit running for approx 10 minutes then remove the copper wire used to jump the two sensors for the water level and place back correctly the cover on the float reservoir.
