2. DESCRIPTION

The machines have been designed to prepare espresso coffee and hot beverages.

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, according to needs.

Model CLUB PU/S has an incorporated water-tank and does not, therefore, need to be connected to the waterworks. A water-softener inside the tank softens the water, filtering the calcium salts in it.

The machine consists of a steel supporting structure on which the mechanical and electrical components are fitted. These are completely covered with panels in varnished steel and stainless steel.

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 machine.

6. INSTALLATION

The appliance is only to be installed in locations where use and maintenance is led to trained personnel.

The machines are fitted with height adjustable feet.

The support surface shall be levelled, dry, smooth, steady and stable and at such a height that the cup-warming surface is at over 150 cm from ground. Do not use water jets or install where water jets are used.

In order to guarantee normal operation, the machine must be installed in areas that the environmental temperature is between +5^ ÷ +32^ end humidity of not over 70% .

It does not need to be anchored to the surface and it does not require any technical operations to dampen vibrations in order to operate properly.

It is recommended to leave the area around the machine free to facilitate its use and the performance of any maintenance operations.

If the machine is wet or very damp, wait until it is completely dry before installing or using it. It is always necessary to request an accurate control to qualified service people in order to find any possible damage to the electric components.

Reserve an area near the machine for the installation of the coffee grinding and dosage machine (see relevant documentation).

The machine is usually equipped with a water softener, type DP2 or DP4, which must be connected by the user in compliance with the laws in force. Should a different softener be installed, refer to the documentation of the relevant product.

A dreg drawer should be fitted by the installer.

6.1. Connections to be made by the user.

Connections must be carried out by qualified personnel in full accordance with federal, state and local regulations.

6.1.1. Water and gas supply (Fig.5)

This equipment is to be installed to comply with the applicable federal, state or local plumbing codes.

Connections must be installed close to the machine.

1) Water drainage pipe 1, having a minimum internal diameter of 30 mm, equipped with a water-trap accessible for inspection.
2) Water supply pipe 2, with a 3/8"G cut-off tap.
3) Gas supply pipe 3, with a cutoff tap.

4) Main switch
5) Volumetric pump (if external to the machine)
6) Softener

Make sure that the maximum supply pressure does not exceed 6.5 Mpa; otherwise, install a pressure reducer.

The machine with gas heating must be installed in compliance with current local laws.

6.1.2. Electricity supply

The machine is supplied ready for connection according to the required electrical specifi - cations.

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 efficient and in compliance with current legal requirements.

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 4 (Fig. 5) at the start of the power cable, complete with magnetic release elements in accordance with the identification plate details (Fig. 1). The contact opening must be equivalent or over 3 mm.

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 qualification, in order to prevent any risks.

6.2. Preliminary operations (Fig.6)

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. Antisuction valve installation (Fig.7)

On the top of the boiler there is the antisuction valve.

When installing the machine be sure to remove the plastic fork "A" and check that the pin "B" is not blocked.

This operation is very important for the correct working of the machine.

Should the flame not light up, avoid insisting and close the gas tap by turning it 90^ in a clockwise direction.

● Wait for the machine to reach its working pressure, gauge needle 13 Fig.8 on green area, and to reach the correct heat level.

8. USE

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

It is dangerous to dispense coffee without a filter-holder in the unit.

● Unclamp the filter-holder from the dispensing unit and knock any grouts out into the drawer especially provided for this purpose, taking care not to damage the rim of the filter.
● Use the filter for 1 or 2 coffees, as required.
- Fill the filter 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 filter while pressing.

If ground coffee is left on the rim of the filter, a leaktight seal is not ensured, with consequent leaking of water and coffee grounds.

• Lock the filter-holder into the dispensing unit firmly to obtain a leaktight seal;
• Place the cups under the spouts and start pouring.

Model PU (Fig.8)

- Press switch 3 to begin dispensing. Once the desired quantity has been obtained, turn the switch back to its initial position to stop dispensing.

Model ME (Fig.8)

● Press the button according to the desired coffee:
A = 1 small coffee;
B = 2 small coffees;
C = 1 long coffee;
D = 2 long coffees.

Dispensing is automatic according to the dose selected.

To deliver a different dose, press key E (led on) to begin continuous delivery.

Press key E again to stop delivery.

To interrupt delivery effected with keys A-B-C-D, press the same key that was used.

- When the coffee has been poured, leave the filter-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 flavour, with only a very small amount of white cream, and if the grounds are too fine, 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.

8.2. Preparing cappuccino (Fig.10)

● Use a high and narrow jug, half-filled with milk;
- Place the jug under the spount 1 so that the nozzle touches the bottom;
● Turn on the steam tap 2 and lower the jug so that the nozzle is almost at the surface of the milk;
● Continuously move the jug up and down so that the nozzle moves in and out of the milk, causing it to froth;
● Turn off the steam tap 2, pour the milk into a cup and add the express coffee.

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 the spout is hot and may burn your hand. Delivery time must not exceed 5 minutes.

8.3. Heating a beverage

●Immerse the steam spout into the liquid to be heated;
● Gradually turn on the steam tap 7 (Fig.8); the steam that bursts in the liquid heats it to the desired temperature.
● Turn off the steam tap when the desired temperature 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 4, Fig.3 and use the delivery control according to the model Fig. 8. When the desired quantity has been obtained, close the tap (dispensing is automatically halted according to the quantity set for models GREEN ME).

During the delivery of hot water electronically dosed, delivery can be interrupted by pressing button 6 Fig. 8.

To adjust the doses, see Paragraph 9.

- Add the desired product.

When purified 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 8.2.

9. ADJUSTING AND SETTING THE DOSE

9.1. Models ME

The doses of coffee and hot water dispensed can be adjusted on the electronically controlled models.

• Place the filter-holder with the ground coffee under the unit to be programmed and the cup (or cups) under the corresponding spouts;
• Keep the E key Fig. 8 of the keyboard located onto the first group on the left hand side pressed for 5 seconds. The flashing leds of the E keys indicate the enabling of the programming phase.
• Within 5 seconds press the appropriate key (A-B-C-D) and visually check the delivery; when the quantity delivered corresponds to the desired amount, press the same key again; delivery ceases and the volume of the dose is automatically memorized.
• Carry out any other adjustment with the same procedure which will also apply for hot water dispensing buttons (2 different doses) Fig.8.

Do not make adjustments to units that do not have a filter-holder with coffee and corresponding cups.

The adjustment made to the first unit on the left also applies to the other units. If you wish to obtain different doses from the other units, the unit on the left must first be adjusted, followed step-by-step by the others.

At the end of the programming phase wait at least 5 seconds before beginning the selections.

The data memorised is permanently stored within the memory even in the case of complete absence of electric power.

9.2.1 Reading of consumed drinks and reading of calculated litres

There is the possibility of reading the consumed drinks (coffee and tea) according to the procedure described hereafter.

To access READING OF CONSUMED DRINKS and LITRES, just press button E (exclusively from push button panel of group 1) and keep it pressed more than 10 seconds.

To exit from the environment of READING OF CON SUMED DRINKS and LITRES, press again the same button at any time.

In this case, buttons A and B perform the special function of incrementing/decrementing the displayed values concerning the reading of consumed drinks.

“Cumulative Total” means the total coffee dispensings made, i.e. the sum of all dispensings made by pressing buttons A-B-C-D-E of each group.

Tea dispensings ARE NOT INCLUDED in the Cumulative Total.

Dosing also offers the possibility of analyzing the details of the total dispensings made by every single "button" of each group.

From the "Cumulative total", by pressing button A the total related to button A of group 1 will be displayed.

Now whenever button A of group 1 is pressed, all totals concerning the single buttons of every group will be displayed in sequential modes ( 1^ , 2^ , 3^ , 4^ and 5^ button for 1^ , 2^ and 3^ group).

If button B of group 1 is pressed, this will enable to go back to the previous total reading.

At the end of the readings concerning the coffee doses of every single group (button 5, group 3), the pressure of button A will enable the user to read the total TEA dispensings made; in this case it will be a total as no reading division between tea1 and tea2 is provided.

If button A is pressed again, this will enable to read the litres calculated up to that moment.

CLOSED: dosing is provided with a NORMAL level sensitivity and safety (approx. 400K)

NOTE: the status relevant to the mobile jumper (open/closed) is detected by 3d5 dosing upon switching on. Do not carry out any variation with board in ON (power supplied) as the modification is detected only after a further Power OFF/ON.

9.2.5 Alarm signalling

Level time out (filling) in the boiler

Whenever the level probe detects lack of water (probe uncovered) the filling phase is enabled (EVCAR + PUMP) while the microcontroller activates an internal timer for the duration of this phase.

If EVCAR+ PUMP remain excited continuously for a time longer than time-out (x seconds) set by means of WIZARD of through the TECHNICAL PROGRAM MING, dosing is inhibited in all its main functions. Keyboards are disabled and all actuators inhibited in every operation

All leds installed on the push button panels start flashing ( 12 ON, 12 OFF) to visually signal the alarm phase to users.

The display will show:

ALARM: TIME-OUT FILLING-UP BOILER

To exit from alarm signalling, perform a Power OFF/ON of the machine (switching off/on).

9.2.6 Absence of pulses of volumetric counter (5 seconds)

After starting a coffee cycle with volumetric control (EVx + PUMP in both dispensing and programming phase), dosing will check the proper running of the volumetric counter by measuring the pulses sent by the microcontroller.

If no pulse is measured for a period longer than 5 consecutive seconds, the led related to the selected dose will start flashing ( 12 ON, 12 OFF).

After 1 minute (volumetric counter Time-out) of absence of pulses of the volumetric counter, the dose under way will be automatically stopped.

12. PROBLEMS AND REMEDIES

Check operations to be carried out by the user with the plug disconnected.

For any type of problem or inconvenience not specifically 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 qualified personnel.

B) There is water under the machine:

• check that the drainage tray is not obstructed.
  C) Slow dispensing:
• check that the filters and delivery heads are clean;
• check that the coffee is not too finely ground.
  D) Irregular steam delivery:
• check that the nozzles are not obstructed.

11. MACHINES WITH ALTERNATIVE GAS HEATER VERSION (Fig.15)

N.B. Installation of the machine and any adjustment or adaptation to the type of gas should be done by a technically qualified person.

The machine leaves the factory all set for use with liquid gas (GPL).

The gas regulator (1) is therefore fitted with the appropriate injector shown in the table below:

Model	Nominal thermic capacity	GPL G30 - 29 mbar	Natural gas G20 - 20 mbar
2 Gr.	2,5 KW (2150 Kcal/h.)	75 102
3-4 Gr	3,3 KW (2850 Kcal/h.)	90 135

The primary air intake regulator (2) is set with the reference notch showing “GPL” corresponding to the fixture screw (3).

The flame is regulated (minimum and maximum) to suit this type of gas.

If the machine is to be used with a different type of gas, it will be necessary to replace the injector in accordance with the above table and to rotate the primary air regulator (2), which, in the case of natural gas, will have to be set with the reference notch showing "N" corresponding to the securing screw (3).

To do this, it will of course be necessary to loosen the securing screw (3) and to tighten it again after rotating the primary air intake regulator (2).

Connections to mains gas, from the gas tap available in the room to the valve fitted on the machine, must be carried out in accordance with the regulations in force, using a flexible pipe or a rigid pipe of soft copper. In the latter case, the special rubber-pipe fitting in connected tightly to the valve by means of the biconical nozzle and securing nut supplied.

The flexible pipe is fitted over the end of the mains outlet and secured with the metal strip supplied.

Alternatively, the soft copper pipe can be connected up, again using the special biconical nozzle and the appropriate nuts, directly to the valve.

Once the machine has been connected up to the gas main, and after filling the boiler up with water in accordance with the instructions in the booklet ("INSTRUCTIONS FOR USE AND MAINTENANCE"), the burner can be lit in the following manner:

- Open the gas exclusion tap.

- Press on the gas valve knob, on the machine rotate it 90° anti-clockwise, and keep it pressed in. At the same time, press the piezoelectric lighter one or more times – the lighter knob bears a symbol resembling a spark – until the burner lights up.

- Wait about 20 seconds, then release the valve knob and the burner should stay lit – the flame is visible through the special hole in the panel behind the dispenser units.

N.B.

Should the burner not light up, do not persist, but release the valve knob, and then check that lighter spark on the burner is in order and about 5 mm long.

Should the flame go out when the valve knob is released, check the position of thermocouple and the circuit connected to it.

The flame should be bright blue; if not, slightly regulate the primary air intake (2) until the desired effect is achieved.

Wait until the machine reaches the correct pressure, according to instructions. Otherwise, adjust the gas pressure regulator, which has two regulating screws.

The one that protrudes more (4) serves to regulate the boiler's operating pressure, while the other (5) serves to set the flame at the minimum.

When the machine is pressurized, check to see that the minimum flame is correct by adjusting the screw (4) if necessary; after loosening the locking-nut, unscrew the screw until it feels loose (the main gas-pipe is closed), and check whether, under these conditions, the low flame remains lit, thus acting as a pilot.

If the flame is too high, it will be necessary to regulate screw (5), turning it slightly clockwise, of course after having loosened the locking-nut. If, on the contrary, the flame tends to go out, then regulate screw (5) by turning it anti-clockwise, until a very low, but constant flame is obtained. Having achieved this correct adjustment of the minimum flame, hold the screw still and lock it with the locking-nut.

Then rotate the screw (4) clockwise until there is a there is a high flame, and wait for the boiler to reach the desired operating pressure: if the flame dies down before reaching the required pressure, tighten screw (4) further; if the flame dies down at a higher pressure, then unscrew the screw.

Check once or twice by opening the steam tap to release the pressure in the boiler, then hold screw (4) still and lock it with the locking-nut.
