The machines in the CLASSE 10 series have been designed to prepare express coffee and hot beve- rages. A positive-displacement pump inside the machine powers the heater in which the water is heated. By pressing the appropriate buttons, water is supplied to the spouts in the form of hot water or steam, ac- cording to needs. The hot water used to make drinks comes from the boiler and is mixed directly with cold water from the water outlet. The machine is composed of a steel carrying struc- ture on which the mechanical and electrical compo- nents are tted. These are completely covered with panels made of aluminium. The beverages are dispensed at the front of the machine, where all the buttons, control devices and dispensers are to be found. There is a cup-warming plate on the top of the ma- chine. Models equipped with gas connections (when applied). A B C D E F USB - ok 2 - 3 - 4 2 2 ok

The machine have been designed, manufactured and protected to be used to make express coffee and hot beverages (tea, cappuccino, etc.). Any other use is to be considered unsuitable and therefore dangerous. The manufacturer cannot be held respon- sible for any damage caused to people or things due to unsuitable, erroneous or irrational use of the machine. The operator must always follow the indications contained in this manual. In the case of a failure or if the machine is not working properly, switch it off and do not attempt any direct repair. Refer exclusively to a service centre. 2.3. Mechanical protective devices The machine is equipped with the following protective devices: complete panelling protection of all the parts subject to heat and of the steam and hot water supplier; cup-warmer plate supplied with a tray to collect spilt liquids; work surface provided with grill and tray to collect spilt liquids; expansion valve in the hydraulic system and valve on the boiler to avoid overpressure; nonreturn valve on the hydraulic system to avoid owing back to the main supply. 2.4.

For additional information on machines equipped with supplementary gas heating options, please consult the user’s manual provided together with the gas kit, supplied on issue with the machine.

Position the machine unit onto the horizontal sur- face provided for that purpose and adjust the base feet to ensure that the machine is stable and that vibrations are limited. Before connecting, thoroughly wash the mains water pipes: Leave the water supply taps running at full pres- sure for several minutes. Connect to the mains water supply. Connect the machine up to the power supply mains. Connect the gas pipe Thoroughly wash all the water pipes of the machine: Leave the water supply taps running at full pres- sure. Switch on main switch 1 (Fig.8): wait until the boiler lls up to the level set. Boiler resistance switch2 (Fig.8) to begin heating the water in the boiler. Once standard machine work conditions have been reached with the machine in “ready for operation” mode, switch the machine off and empty all the wa- ter lled into the water circuit the rst time, thereby eliminating any possible initial impurities. Fill the machine up with water again and set it into standard operation mode. Once the “ready for operation” status is reached: - Connect the lter-holders to the dispenser units (without coffee); operate each group head in order to allow the water to escape for about one minute. - Dispense hot water until at least 2 liters of water have been dispensed from the 1-group or 2-groups compact, 5 liters from the 2-groups machines, 8 liters from the 3-groups machines and 11 liters from the 4-groups machines. - Open each steam dispensing point for 1 whole minute. Once installation is terminated, the installa- tion technician MUST issue an installation report.

6.1.2. Electric supply

The machine is supplied ready for connection according to the required electrical specications. Before connecting the machine ensure that the plate details comply with those of the electric distribution network. The electrical connection cable must be directly connected to the connection provided according to current legislation. Ensure that the earthing system is efcient and in compliance with current legal re- quirements. The earthing system and the lightening protection system must be realized in accordance with the provisions of current legislation. For the supply network use a cable in compliance with standards with protective conductor (earthing wire). For three-phase power use a cable with 5 conductors ( 3 phases + neutral + earth). For single phase power supply use a cable with 3 conductors (phase + neutral + earth). In both cases it is necessary to provide an automatic differential switch (Fig. 6) at the start of the power cable, complete with magnetic release elements in accordance with the identication plate details (Fig. 1). The contacts must have an opening of equal or over 3 mm and with dispersed current protection of 30 mA. Remember that each machine must be tted with its own safety elements.

Should the power supply cable be damaged it is to be replaced by the manufacturer or by its technical assistance service or by person with equivalent qualication, in order to pre- vent any risks. 6.2. Preliminary operations (Fig.7) POTENTIAL-EQUALIZING CONNECTION This connection, which is the one called for by several norms, avoids electrical potential differences, building up between any equipment that may be installed in the same room. There is a terminal clip on the under side of the base of the machine to which an external potential-equalizing wire should be connected. This connection is ABSOLUTELY NECESSARY and must be made right after the machine is installed. Use a wire whose cross-sectional area conforms to the existing norms. 6.3.

To interrupt brewing once the operation has been activated with buttons A-B-C-D, press the same button again or press E. Each time a coffee is dispensed, the LED of the relative button lights up. If pressed for approx. 8 sec., the dose quantity programming function is accessed. During dose programming, the LED of the 5

button ashes rapidly. If the dose is supplied irregularly or the volumetric counter is malfunctioning, the LED of the pressed button ashes dispensing the dose on a time ba- sis. 6 Hot Water and Cup-Warmer Panel (mod.S-RE)

6.1 Cup-warmer switch with two positions:

With switch ON, the LED ashes and the cup warmer resistance is energized. With switch OFF, the LED switches off and the resistance is de-energized.

6.2 Two-position hot water switch (thermoregula-

ted): With switch ON, the LED ashes and thermore- gulated hot water is dispensed. With switch OFF, the LED switches off and dispen- sing stops.

6.3 Hot water switch (picking up directly from the

boiler) with two positions: With switch ON, the LED ashes and hot water is dispensed directly from the boiler. With switch OFF, the LED switches off and dispen- sing stops. 7 Hot Water and Function Panel (mod.USB) This panel features 5 buttons and 5 LEDs consi- sting of the following: 1 cup-warmer button (7.1) 2 buttons for dispensing hot water (7.2 - 7.3) 3 keys for dispensing hot water blended with the temperature control function (7.3 - 7.4 - 7.5)

The function provides for 4 setting levels of resi- stance heating strength: off, minimum, medium, maximum (pls. consult par. 9.5).

When the button is pressed, hot water is dispensed directly from the boiler for the set time or until the button is pressed again. If the key is kept pressed in for 2 seconds, the dispensing ow becomes continuous and it will stop only if the key is pressed in again. The dispensing ow is anyway stopped automati- cally after 30 sec.

7.3 – 7.4 – 7.5 Hot water blended with the tempe-

rature control function (4-TEA) Pressing on any one of the keys will start dispen- sing of the temperature-controlled water for the set amount of time, or until the key is pressed in again. During this dispensing cycle, the pump starts up. The default programming of the 3 keys provides for different water temperatures, ranging between 85°C (7.3) and 60°C (7.5). The temperatures and the dispensing times can anyway be program- med. It is also possible to set a dispensing option providing cold water taken directly from the water mains line. If the key is kept pressed in for 2 seconds, the di- spensing ow becomes continuous and it will stop only if the key is pressed in again. The dispensing ow is anyway stopped automatically after 30 seconds.73 When the water reaches the correct level, the pump stops. Turn the main switch 2 to begin heating the water in the boiler then turn each one until water begins to ow from them. Wait for the machine to reach its working pressure and to reach the correct thermal balance. Models with gas (Fig.8) Turn on the water supply tap 2 (Fig.6). Turn on the gas tap 3 (Fig.6). Turn the main switch 1; the pump is activated, lling the boiler. When the correct level is reached, the pump stops. Turn the switch 2. Turn the gas tap 10 to the vertical open position and hold down the incorporated button, at the same time repeatedly press hard on the piezelectric but- ton 11 until the spark lights the gas ame (carry out this operation looking through window 14). Hold the tap button 10 down for approx. 30 seconds to allow the safety system to keep the ame lighted. If the ame goes out, repeat the operation. Should the ame not light up, avoid insisting and close the gas tap by turning it 90° in a clockwise direction. Wait until the machine reaches its working pressure and until the correct thermal balance is achieved.

Press the button to excite the steam and emulsion delivery electromagnetic valves until the program- med temperature and froth level are reached or until the function is switched off.

Pressing the key excites the steam distribution electro-valves until the programmed temperature is reached or until the same is pressed again. Safety Devices Dispensing cannot be carried out if the machine has not reached the operating pressure or temperature at least once, and each time that the boiler pressure drops too much. 8 Steam supply handwheel “C-LEVER”: Rotating the turn-knob upwards will open the tap; the turn-knob will remain in open position to allow for a continuous steam supply. To close the tap, turn the turn-knob back into its horizontal position. Rotating the turn-knob downwards provides for instant steam supply. Once it is released, the turn- knob will go back into its horizontal position and the steam supply is instantly stopped. 9 Supplementary manual water lling tap posi- tioned under the discharge basin.

WATER CHANGES: at the start of each daily activity and anyway always after machine stop periods longer than 8 hours, it is necessary to change 100% of the water contained in the circuits via the points appropriately provided on the machine for the purpose. USING THE STEAM WAND: Before using the steam wand, it is always necessary to ush out all the resi- dual steam condensate for at least 2 minutes. The machine has a top shelf on which the cups are kept and heated, ready for use. This is very important to obtain good coffee as the pre-warmed cup stops the coffee from growing cold too quickly. 8.1. Preparing coffee Unclamp the lter-holder from the dispensing unit and knock any grouts out into the drawer especially provided for this purpose, taking care not to dama- ge the rim of the lter. Use the lter for 1 or 2 coffees, according to need.74 8.2. Preparing cappuccino (Fig.9) Make cup of cappuccino with the express coffee. Use a high and narrow jug, half-lled with milk. Place the jug under the spout so that the nozzle touches the bottom. Turn on the steam tap and lower the jug so that the nozzle is almost at the surface of the milk to create the froth. Turn off the steam tap and pour the milk into the cup. Immediately after carrying out this operation, clean the spout with a sponge or a clean cloth so that the milk does not dry on it. Be careful as the spout is hot and may burn your hand. 8.3. Heating a beverage Immerse the steam spout into the liquid to be heated. Gradually turn on the steam tap 8 Fig.8; the ste- am that bursts in the liquid heats it to the desired temperature. Turn off the steam tap when the desired tempera- ture has been reached. Immediately after carrying out this operation, clean the spout with a sponge or clean cloth. Be careful as the spout is hot and may burn your hand 8.4. Preparing tea, camomile, etc. Place the jug under the hot water spout and use the delivery control according to the model (Fig.8). When the desired quantity has been obtained, turn off the switch. Add the beverage desired. Models USBFor these models, hot water is dispensed in specic measures (see paragraph 9, adjusting the dose of hot water). To dispense hot water in different quantities, proceed as follows: Hold down the delivery control 7.2 o 7.3 o 7.4 o 7.5 (Fig.8) for at least four seconds then release the button; the machine continuously delivers water. When the desired measure has been obtained, press the button E again to interrupt delivery. When the dose of hot water is being delivered electro- nically, delivery can be interrupted by pressing the button 7.3. When puried water is used, these beverages often assume a darker colour. Should the user prefer a lighter coloured drink, draw fresh water from an ordinary tap and proceed with the heating phase as described in point 8.3. Fill the lter with the measure of coffee, level it off and press it down gently with the presser. Remove any ground coffee that has stuck to the rim of the lter while pressing. If ground coffee is left on the rim of the lter, a leaktight seal is not ensured, with consequent leaking of water and coffee grounds. Lock the lter-holder into the dispensing unit rmly to obtain a leaktight seal. Place the cups under the spouts and start pouring using control 3 - 4 or button panel 5 according to model (Fig.9). When the coffee has been poured, leave the lter- holder attached to the dispensing unit until the next coffee is required. When pouring, beware of the hot parts of the machine, especially the coffee dispensing units, the steam and hot water spouts. Do not put your hands for any reason under the units and the spouts when they are operating. The grinding of the coffee beans is of fundamental importance to the making of good coffee, and the granular texture of the resulting grounds should be such that it takes 25-30 seconds to produce the beverage. If the coffee is ground too coardsely the coffee will be pale in colour and weak in avour, with only a very small amount of white cream, and if the grounds are too ne, the coffee will be dark with no cream. Good coffee can only be made if the beans are freshly and uniformly ground (only possible when the blades of the coffee grinder are sharp) and are then measured out into the correct quantities (roughly 6 grams per measure). The importance of freshly ground coffee beans is due to the fact that once ground, they rapidly lose their aromatic qualities, and fats present in the beans go rancid.75 8.5. Machines with iSteam automatic system (Fig.8) (only Mod. USB)

8.5.1 Heating Milk or a Drink (iStema)

Immerse the wand in the drink Press button 7.7 on the keypad (Fig.8) The display will show the temperature of the drink Press button 7.7 again to stop heating at the de- sired temperature. Wait for dispensing at the programmed temperatu- re to stop automatically, otherwise press key 7.7 in again to stop the drink-heating function manually. Should heating the drink above the set temperature be required, hold key 7.7 pressed in. The steam dispenser nozzle will continue supplying steam until a maximum temperature of approx. 90°C is reached, or until the key is released again.

8.5.2. Preparing Frothed Milk (iSteam)

Immerse the wand in a container containing at least 250 cc of milk (the sensor must be at least 3 cm below the water level). To obtain best results, use refrigerated milk (≤ 5°C) - (≤ 41°F) Press button 7.6 on the keypad (Fig.8) The display shows the temperature of the milk. Press button 7.6 again to stop the machine at the desired temperature and emulsion level. Wait for dispensing at programmed temperature and at programmed cream level to stop automatically, otherwise press key 7.6 in again to stop the drink emulsion function manually

9. ADJUSTMENT AND SETTING OF THE

DOSE 9.1. Models USB It is possible to adjust the dose of coffee and hot water dispensed by electronically controlled models. (If the function is enabled)

9.1.1. Adjusting the dose

The quantity of coffee and hot water dispensed can be adjusted using the button panel or the hot water controls. 1 Press the button E on any button panel and hold it down for 8-10 seconds until water stops owing from the dispensing unit and the led of the conti- nuons button on the rst button panel on the left begins ashing. The following page displaying the services selec- tion keypad and the coffee selection will come up on screen. 2 It is necessary to act as to make 1 or 2 cups in or- der to reach the correct coffee amount adjustment in the cup. 3 Put the lter-holder (with ground coffee) on the left unit and the cup under the spout. 4 Operate the selected button (i.e. button A for one small cup). 5 One the required coffee amount in the cup has been reached, press the stop button A. Coffe will stop pouring and the microprocessor will store the dose. The screen will display the impulses relative to the completed dose and a data box will highlight that it has been stored into the system. 6 Press the continuous button E again; the led will go out and the machine will store the new quantity. 7 Make the coffee and check the cup amount in order to check that programming is correct. If some doses have to be changed (A-B-C-D), once at point 5 repeat the instructions in points 3-4-5 for each dose, remembering to use the lter-holder with relevant lter and freshly ground coffee. Then carry out point 6 and repeat point 7 to check all changed doses. If all units are to be programmed with the same doses, the selection of coffee doses is nished. If the dosage of another unit is to be changed (1-2-3-4 doses), pro- ceed as indicated in the above-mentioned point 1-7, using only the button panel of the selected unit.

9.1.2. Adjusting the quantity of hot water

Proceed as follows: 1 Press the continuous E button on any button panel and hold down for 8-10 seconds until water stops owing from the dispensing unit and the led of the E button on the rst button panel on the left starts ishing. The machine is ready to accept quantity variations. 2 Put a cup or a jug to receive the water under the water spout 17 (Fig.3). 3 Push the delivery button 7.2. 4 Once the required amount is reached, press the button 7.2 again. Water will stop pouring and the microprocessor will store the dose. - To adjust the water dose for the dispensing beak 4 (Fig. 3), carry out the same steps using either key

7.3 or 7.4 or 7.5. Temperature-controlled water is

not dispensed during this phase. 5 Once adjusted, press the stop-continuous button E on any button panel; the led will go out and the machine will store the new quantity. 6 Pour out doses of hot water to check that program- ming is correct.76 9.2.

9.2.7. Procedure for replacing the water inside

the boiler with fresh water Hot water is emptied out from the nozzle spout Fig.3 – item 8, until the boiler is empty. When emptied, fresh water is lled in automatically until the set level is reached. During the nal phase, the boiler is heated up until the set pressure is reached. During the boiler water emptying-out operations, the boiler level control and resistance functions are OFF. For water removal, we recommend the insertion of a tube leading from the nozzle spout directly into the discharge drain. This to avoid water squirts. ESC can be pressed at any time to interrupt the cycle.

WARNING: Water may spill out during the

During the warming up phase, the following message is displayed: “Machine not ready” Until the set pressure is reached. The following messages are also displayed, con- cerning: “Please make the regenerate softener”, if the function is enabled and the set values have been reached (this message will be then repeated every hour until it is reset) “Please make the service time”, if the function is enabled and the set values have been reached (this message will be then repeated every hour until it is reset)

Keep “ENTER” button pressed to start washing until the display shows: Coffee Cleaning Cycle Start cleaning cycle Group? press <ENTER> If you press “enter” within 10 seconds, the following cycle starts (if you do not leave this menu automa- tically): - The display shows: Coffee Cleaning Cycle Insert the blind lters then press <ENTER> - When you press “enter”, the cleaning cycle starts and the display shows: Coffee Cleaning Cycle CLEANING RUNNING The machine carries out n. 10 cycles as follows: - Starts dispensing from the groups for 10 sec. - Pauses for 10 sec. At the end of the 10 cycles, the display reads: Coffee Cleaning Cycle Remove the lterholders press <ENTER> If you press “enter” the display shows: RINSE RUNNING The machine carries out n. 2 cycles as follows: - Starts dispensing from the groups for 30 sec. - Pauses for 30 sec. Keeping ‘’esc’’ pressed for 2 seconds, during the cycle the current washing phase will stop and the next phase will take place. It is advisable to always complete the rinsing cycle to remove any detergent residues. N.B. In the washing and rinsing phases the groups are operated alternatively. In any case the washing of the coffee groups can be enabled whenever necessary according to the previously described procedure. Remove the lters and immerse them with the lter holders in the prepared solution, leaving them for at least 10/20 minutes (all night is better). Remove them from the container and rinse them thoroughly in running water. Remove the cup rack 1 (Fig.12), slide out the drip tray and clean them both. Check and clean the drainage sump 4 (Fig.14), removing any sludge with the help of a spoon.

Maintenance operations have to be carried out when the machine is off and cold and the plug is disconnected. Some particular operations have to be effected when the machine is operating. Do not clean the machine by using metal or abrasive devices, such as steel wool, metal brushes, needles, etc. or general detergents (alcohol, solvents, etc.) When necessary, use special detergents for coffee machines that can be bought in specialized service centres. 11.1. Daily (Fig.10) Use a clean cloth or sponge that does not leave hairs or uff (preferably cotton or linen). Carefully clean the outside surface, following the grain of the satin nish on the parts in stainless steel. Clean the steam and hot water spouts and check that the nozzles are not encrusted (if they become encrusted, be careful not to deform or damage them). Clean the spray units and the seals under the ca- sing of the delivery units using the special brush supplied. Remove the lter-holders and remove the lter and the clamp which secures the lter, use a brush to remove any coffee deposits and rinse with hot water in order to dissolve any grease deposits.83

12. STOPPING THE MACHINE

A - Temporary stop Carry out cleaning and maintenance operations. Wind up the cable and fasten it to the machine with sticky tape. Cover the machine and place it in a dry room. Do not leave it exposed to atmospheric agents and do not allow it to be touched by children or unift persons. To disconnect from the main power supply, consult qualied personnel. B - Denitive stop Besides carrying out the operations necessary for a temporary stop, cut off the cable, pack the ma- chine in cardboard, polystyrene or other packing material and consign it to rms authorized for its disposal or to second-hand goods dealers.

13. TROUBLESHOOTING AND POSSIBLE

REMEDIES Check operations to be carried out by the user with the plug disconnected. For any type of problem or inconvenience not specically indicated, disconnect the plug and contact our service centre without attempting any direct repairs. A) The machine does not start: - check that the plug is connected; - In case of power failure wait for the power to return and check if the earth leakage protection circuit breaker or the main switch is on; - check the condition of the plug and the supply cable; if damaged have them replaced by qualied personnel. B) There is water under the machine: - check that the drainage tray is not obstructed. C) Slow dispensing: - check that the lters and delivery heads are clean; - check that the coffee is not too nely ground. D) Irregular steam delivery: - check that the nozzles are not obstructed.

11.2.2. Cleaning iSteam

Clean the iSteam nozzle frequently with a sponge or damp cloth. Make sure to clean the lower parts. Check to make sure that the sprayer is not clogged or partially clogged with crusts and residues (if a crust removal operation is necessary, be very careful not to deform or damage the sprayer) 11.3. Regular-interval maintenance and repairs During all maintenance / repair operations, the components used must be warranted to maintain all the machine’s hygiene and safety requirements. Using the machine’s original spare parts constitute an effective warranty. After repair or component replacement operations involving parts coming into contact with water and/or food, it is necessary to run the machine washing procedure as specied under the installation and rst-time start-up section herein. Have been tted with economizers which do not draw water from the boiler to make hot water, the water in the boiler need only to be renewed from time to time.

11.3.1. Renewal of water in the boiler

(Fig.12) To be carried out only by qualied personnel. Turn off the machine and wait for the pressure in the boiler to diminish (gauge needl on “0”). Insert a rubber hose into the hose-end tting (3) (Fig.12) Use the wrench (1) to immobilize the tting (2) and loosen the hose-end tting (3). Allow the water to ow out completely; then, close the tting (3) and remove the rubber hose. Rell the boiler (paragraph 7.3.). Whenever descaling operations are necessa- ry, ensure that only specic products suitable for parts contacting water for public, human consumption are used. Make sure that all the relative product instructions are carefully observed and complied with at all times.84
