Before proceeding with installation check that: - there are no bumps, signs of knocks or deformities.

ELECTRICAL CONNECTION Important ! Before proceeding with electrical connection it is necessary to check to ensure that the voltage rating corresponds with that indicated on the CE plate and on the connection plate on the power supply cable.

1 there are no damp patches or marks which could lead one to assume that the packaging has been exposed to the elements 2 there are no signs of tampering

Check to ensure that the electrical supply line is able to support the machine load (see chap. 4 – technical features table).

Once one is satisfied that transportation has been correctly effected proceed with installation.

Connect to an earthing socket which complies with current legislation. Check that the power supply cable is efficient and that it complies with national and European safety standards.

Proceed with installation following the instructions according to the sequence as described below.

The user must undertake to power the machine protecting the power line using a suitable safety switch (cut-out) that complies with the legislation in force in the actual country itself.

5.1 WATER CONNECTION Connect the power cable (1) to the electric line using a plug, or in the case of fixed installation, using a multi-polar switch (D) for mains separation, with a contact distance of at least 3 mm.

Important: The machine must be supplied with water of over 8°F hardness.

For voltage change refer to the diagram shown on the general mains switch box. The yellow-green coloured cable MUST be connected to the room’s earthing system.

The installation of a water softener is recommended for the machine water supply. Check that the water mains to which connection is to be made supplies drinking water. -

Connect purifier (E) to the water mains (A).

NB: before connecting the purifier to the machine, wash out thoroughly until the water becomes clear, then proceed to connect the purifier to the machine. -

Connect the drain cup (G) to the drainage pipe (B)

Should the mains pressure be higher than 5 bar a pressure reducer balanced for high pressure should be installed (device in which any mains pressure increase does not effect the output pressure).

GAS CONNECTION Connect valve (H) to duct (C) using a rubber hose (in compliance with current standards) and suitable hose clamps or use the connection supplied for stainless steel hose (as indicated in figure in section 8 “Gas adjustment”.

Once the water, gas and electrical connections have been made, proceed to start up the machine.

IMPORTANT Do not press the hot water delivery switch or button (2) before the correct working temperature of 1.1 atm is reached, as indicated on the boiler gauge (10).

Open the mains water supply tap (A). Close the protection switch (D) Position the machine main switch (8) to position on indicator will come on (3).

The auto-levelling device will come into operation so that the water reaches a normal level in the boiler (12).

LONG COFFEE GIGLEUR The machine is fitted with a gigleur ( 1 per unit) with a clearance of 0.6 mm (Cod.26G0074/01).

Position the main switch (6) to position for operation at normal power or to position for operation at full power, thereby powering the resistances.

For greater coffee delivery speed, in the case of long coffees, no.2 gigleurs are also included with the machine (complete with seals) with a clearance of 0.8 mm (Cod.26G0073/01).

Wait for the pressure to reach its operational pressure 1.1÷1.3 atm checking the boiler pressure on the gauge (10).

The gigleur is located in the exchanger supply fitting (1 per group).

Should the machine fail to stabilize on the indicated values it is necessary to calibrate the pressure switch as described in paragraph 6.2. In the event of a machine featuring a gas heating system, it is necessary to switch on the gas by operating the gas valve (4) after operating the main switch (6), keeping the piezoelectric switch pressed (5) until the gas remains on. Then check the pressure on the pump gauge (10) putting a unit into operation with filter holder engaged filled with ground, dosed and pressed coffee in order to achieve an effective working pressure of 8/9 atm. Should re-calibration of the pump pressure be necessary this operation should be undertaken as indicated in paragraph 6.3. The machine is now ready for use.

6.2 PRESSURE SWITCH ADJUSTMENT Warning !! When the machine is new the filter-holder sump may not be aligned (perpendicular to the machine itself) as shown in the figure at the side, however this does not effect the efficient function of the same. After a short period of use the sump will gradually settle into a correct position.

The pressure switch shown in the figure acts to keep the boiler pressure constant by engaging or de-activating the electrical heating resistance. This pressure switch is already calibrated to 1.1-1.3 bar during the initial machine testing stage, but should a different working pressure be required, it is possible to vary the operational field of the pressure switch using the regulation screw (U); pressure reduction results in a reduction in temperature, whilst increasing the pressure will also increase the water temperature.

A = Position of closed filter-holder with new machine. B = Position of closed filter holder with machine after a short period of use.

The regulation direction is shown in the figure and on the pressure switch itself. The pressure varies by 0.1 atm for every complete screw turn,

B Warning: Disconnect the electricity supply before undertaking this operation.

U A IMPORTANT: N°2 under-tile packings with are thinner (8.1mm ) than that fitted as standard are included. These packings may be used in the event of difficulty with insertion of the filter holder.

6.4 FILTERS FOR COFFEE MACHINE Depending on the quantity of coffee ground, the appropriate filter must be as shown below to avoid that, once the coffee has dripped out, the leftover powder remains attached to the nozzle.

Insert the filter holder into the unit filled with regularly ground, dosed and pressed coffee. Switch on the unit switch or the unit control keyboard (16) and read the pressure on the pump pressure gauge (10). NB: The correct pressure is of 8-9 atm. Should the pressure indicated on the pressure gauge be incorrect, turn it clockwise to increase the pump pressure and anti-clockwise to reduce the pressure. Once adjustment is complete check pump calibration by delivering one or more coffees.

FUNCTION / USE AND PROGRAMMING INTRODUCTION The programming software permits the checking of the following operations: - handling of 2-3-4 coffee units -

simultaneous function of both coffee and tea units

cappuccino/milk function

volumetric check on coffee measures

timed tea measure check

simulated measure programming

filling level check and control

system supervision through alarms

continuos, delivery time-out and further functions

serial connection with accounting devices

16 X 2 LCD display (not rear-lit) for functional state display.

Keyboard symbols: T1 Single espresso coffee

Important: the last selection made always appears on the display

COFFEE MEASURE PROGRAMMING The measured amounts of coffee may be modified (by means of volumetric checking) and memorized as follows: -

press key T5 (of keyboard relative to group 1) and keep pressed for over 5 seconds and check that all the keyboard leds come on. In which case, (by operating on the keyboard relative to group 1) all the units will be programmed, while by pressing key T5 of another unit, only the programming of the unit on which one is operating is possible.

IMPORTANT !! The settings made on unit 1 (operating on the first keyboard) will be automatically copied on to all the other units.

ENGLISH Press the key corresponding to the measure to be programmed (key T1 for example) within 30 seconds (programming time-out). The led relative to T5 will remain on, on all keyboards and the led relative to the measure being programmed will also come on (on all the keyboards). During this state and for the entire coffee measure programming time duration, the solenoid valve and pump are activated.

Note: If none of the keys are pressed within 30 seconds, it will automatically escape from programming mode.

On pressing key T1 coffee delivery begins, once the required amount of coffee is obtained press key T1 again or any other of the keys of the unit keyboard in order to suspend coffee delivery. The new impulse value of the measure is thereby memorized on the EPROM. Both the solenoid valve and the pump are de-activated thereby suspending product delivery and all the keyboard leds go out.

To proceed with a new programming operation of other coffee measures T2-T3T4 (providing that the programming time out time of 30 sec is not exceeded) simply repeat the same operations with the same sequence as undertaken for key T1.

Press key T5 to immediately escape from the programming stage.

IMPORTANT: Should the “PRE-INFUSION” function be active (see par. 7.5). Wait until the pre-infusion function is complete before stopping delivery in progress.

NOTE: During the programming of a unit the function of the other units is deactivated as well as tea dispensing.

To programme the other units, press the specific programming key of each unit and carry out the same operations as undertaken on unit 1. In this case any variations in the measures are activated only on the unit on which one is actually working.

TEA MEASURE PROGRAMMING (HOT WATER)

It is possible to modify the timed tea measures according to the following sequence: Press key T5 of coffee unit 1 and keep pressed down for over 5 seconds and check that all the keyboard led indicators come on. Press the T8 tea key within 30 seconds (programming time-out). This begins the tea water delivery operation. Once the required measure is obtained press T8 again to suspend water delivery. In this way the new tea water delivery time is memory and all the keyboard leds go out. Press key T5 again to immediately escape from the programming phase.

COFFEE DELIVERY On pressing the corresponding key T1-T2T3 or T4, the corresponding delivery solenoid valves are activated for the time necessary to obtain the required amount of product as previously programmed (volumetric check). The LED relative to the selected measure remains on for the entire coffee delivery time. The delivery in progress may be suspended before actually reaching the desired programmed product quantity by pressing any of the measure keys present on the keyboard of the unit used for product delivery. It is also possible to obtain simultaneous coffee delivery from all the machine units.

CONTINUOUS COFFEE MEASURES For continuous coffee measure delivery press key T5 from the keyboard corresponding to the unit on which one wishes to operate. The LED corresponding to key T5 will remain on for the entire delivery operation.

IMPORTANT ! Avoid keeping it pressed for more than 5 seconds or it will enter the programming mode. Coffee delivery will continue until measure stop by pressing key T5, or on obtaining the maximum amount of product which can be obtained through volumetric control (6000 impulses) or by means of delivery Time-out function.

IMPORTANT ! The start of the relative “continuous” cycle occurs on the release (within 5 seconds) of key T5 and not on pressing of the same. While the STOP function may be obtained by pressing it a second time.

SPECIAL FUNCTIONS It is possible to engage or deactivate certain special functions such as PRE- INFUSION, MIXED TEA and WASHING ALARM which we shall describe below:

PRE-INFUSION MIXED TEA (HOT WATER)

Our software permits measure configuration so that the relative delivery of the COFFEE measures through volumetric control is preceded by pre-infusion. Delivery of the coffee measure after time 1 (ON) is suspended for a time 2 (OFF) and is then resumed for the completion of selection. On pressing one of the volumetric control measure keys, the normal delivery cycle is preceded by a short timed water jet in order to dampen the coffee pellets before actual delivery stage. This function ensures the optimum use of the coffee pellets.

On the engagement of this function the water delivered is mixed with cold water on entry in the boiler thereby ensuring constant delivery at a temperature of about 96°C. If this function is not engaged water is delivered at a temperature of about 100°C and is highly vaporized.

WASHING ALARM This function acts to indicate, after 10 minutes from the start of the delivery of the cappuccino or milk, the following signal “Run Milk Clean” and the alternating flashing of the LEDs corresponding to keys T6 and T7 which indicate that a milk or cappuccino has been prepared and the milk section therefore needs to be cleaned. To temporarily cancel the alarm function press key T6 or T7.

CAPPUCCINO MACHINE CLEANING Cleaning to be undertaken when the “Run Milk Clean” message appears with the alternating flashing of the LEDS corresponding to keys T6 and T7. Take a 1 litre container full of cold water. Remove the milk suction pipe from the container and place inside the container itself. Press keys T7 anf T5 at the same time (on the keyboard activated for the “service” functions) this engages the milk delivery function, the water flow will clean the cappuccino machine. Once all the water has been suctioned, stop delivery by pressing key T7.

ENGLISH ENGAGEMENT/DEACTIVATION Start the machine by pressing the main switch keeping key T5 of unit 1 pressed and wait for the led relative to key T5 to begin flashing. Press keys T1-T2 and T3 in order to engage or deactivate the PRE-INFUSION, MIXED TEA and WASHING ALARM functions.

T1 KEY LED ON : PRE INFUSION: T2 KEY LED ON : MIXED TEA: T3 KEY LED ON : WASHING ALARM:

ON ON ON To escape from this condition and return to normal functions press key T5 again.

7.6 TEA DELIVERY On pressing key T8 the corresponding solenoid valve is engaged thereby beginning hot water delivery. On START a timer is activated which interrupts the water delivery on reaching the time set during the programming stage. The simultaneous delivery of tea or coffee is possible. It is possible to interrupt delivery function in progress before the programmed time is reached by pressing key T8 again used for product delivery.

CAPPUCCINO AND MILK FUNCTION It is possible to set the CAPPUCCINO and MILK function on keys T6 and T7 on group 2,3, or 4.

IMPORTANT : The function can be set on only one keyboard at a time, on unit 2, 3 or 4.

ENGAGEMENT/ DEACTIVATION In order to set the function on the keyboard of unit 2, for example, keep key T5 pressed down and the corresponding LED will begin flashing until the wording “SERVICE OFF” appears on the display.

Press key T1 of keyboard 2 in order to engage the Cappuccino/milk function on the 2nd unit. T1 KEY LED ON : SERVICE:

ON Proceed in the same way to engage this function on the keyboard of another unit.

CAPPUCCINO DELIVERY AND PROGRAMMING When engaged key T6 will determine the activation of the solenoid valve and pump according to the value set during programming. To programme the cappuccino function, proceed in the same way as for coffee with the only difference being that at the end of the volumetric delivery of the coffee, the timed milk delivery BEGINS SEPARATELY. Once the desired quantity is obtained stop delivery using key T7.

MILK PROGRAMMING AND DELIVERY Key T7 when engaged determines the activation of the solenoid valve according to the value set during programming. The programming of this function is the same as that for TEA.

7.10 FURTHER FUNCTIONS ON MACHINES EQUIPPED WITH DISPLAY LANGAUGE SELECTION In order to select the consultation language, on switching on, press key T4 and keep pressed.

Press key T1 several times to select the desired language, press T4 again to confirm selection.

ENGLISH CONSUMPTION READING It is possible to read the consumptions that have been made following the instructions indicated below. Press key T5 (of 1st unit only) and keep pressed for over 10 seconds. The display will show the dispensing operations undertaken : press key T5 again to escape from this condition. By pressing key T1 (forward) or T2 (back) it is possible to consult the various memorized consumption values.

On pressing key T1 of unit 1 on goes on to the consumption values of the keys of unit 2 and so on in succession.

ENGLISH After visualization of the data of the last coffee unit also, on pressing key T1 it is possible to obtain a reading of the number of TEA dispensing operations made.

To cancel the totals of the individual consumptions (but not the “total cumulative” data), press keys T3 and T4 of unit 1 for 3 seconds in the condition in which “CUMULATIVE TOTAL” is displayed.

7.11 ALARM CONDITION BOILER (FILLING) LEVEL TIME OUT This alarm condition occurs whenever the water level is too low or the level probe remains uncovered. In such a case the keyboard leds flash and an alarm message appears on the display. The filling stage is automatically engaged and to cancel the alarm conditions switch the machine off and then on again.

Lack of volumetric counter impulses On starting a volumetric control coffee cycle, the correct function of the volumetric counter is checked by the reading of the number of impulses sent by the same to the micro-controller. Should no impulses by recorded for a period exceeding 5 seconds the LED relative to the selected measure begins flashing (ie. the led relative to key T4). After one minute in which no impulses are recorded (volumetric counter time out), the measure underway is automatically stopped.

regeneration after 1600 l

shift levers C and D from left to right as shown in fig.8.2 and remove the cover by loosening knob G, pour in 1.5 kg of sodium chloride (coarse cooking salt) into the 8-litre purifier and 2 kg into the 12-litre type.

Replace the lid and shift lever from right to left as shown in fig.8.3 and allow the salted water to drain out of pipe F until the water is fresh.

Shift lever D from right to left as shown in fig.8.4

NB: These regeneration instructions are valid only providing the purifier is as that indicated in the figures. Should it fail to correspond proceed as indicated in the instructions attached to the purifier itself.

The machine is set up for being supplied with methane gas (G20), this means that the gas injector (O) and the gas regulator (N) are calibrated for methane gas.

Wait for the boiler to reach an operating pressure of 1.1÷ 1.3 atm and for the flame to be reduced to a minimum. If the gas regulator (N) requires calibration, proceed as follows : turn the minimum adjustment screw (Q) clockwise to reduce the flame and anticlockwise to increase it.

For operation with GPL gas (liquid gas G30) or town gas, the gas injector (O) must be replaced with the injector enclosed with the machine (see gas injector table).

To increase or reduce maximum pressure in the boiler, turn the pressure adjustment screw ® clockwise to decrease the pressure and anti-clockwise to increase it.

To light the gas burner keep the gas n-oiff valve button (4) pressed down in order to allow the gas to flow to the burner, then operate the piezoelectric ignition push-button (5).

NB: The on-off valve button must remain pressed down for a few seconds to allow the thermo-couple to operate. Adjust the air flow by means of the air adjustment ring nut (P) turning clockwise to reduce the flow and anti-clockwise to increase it, so as to obtain a blue flame (avoid long or excessively oxidising flames to avoid damaging the boiler).

10 - MAINTENANCE AND USEFUL ADVICE It is a good idea to rinse the filters (C) and filter holders (D) every day in hot water, or even better, place them in hot water and allow to soak for the whole night in order to dissolve any greasy coffee deposits.

In order to ensure that the spouts (B) are kept clean and free of any coffee deposits which may jeopardize yield, we advise that before starting work in the morning that you put filter holder (D) in with empty filter (while machine is hot) and operate the unit several times.

It is advisable to leave the filter-holder cups inserted with the coffee dregs for the entire working day to ensure that the filter-holder is always at optimum temperature.

In this way any coffee dust which may have been deposited between the metal filter (B) and the metal filter holder (A) are removed. This operation must be repeated every day.

Do not cover the cup-warmer level with any fabrics or cloths etc. Do not use any abrasive or corrosive products for cleaning the bodywork.

Frequently check the filter holes (C) and remove any deposits. Should the water have been left in the ducts for a long time, it is necessary to allow some water to flow through them in order to remove any deposits.

A B C D E F G H The steam nozzles must be cleaned immediately after use in order to prevent the risk of the formation of any scale which may block the holes and to ensure that any drinks made subsequently do not absorb any unpleasant odours.
