Before starting installation, you need to ensure that:

1. no dents, bumps or buckling exist;
2. no wet areas or other signs exist that may lead to the conclusion that the packaging has been exposed to bad weather conditions;
3. no tampering signs exist.

Once you have ensured that transport has been carried out correctly, proceed with installation.

Check that the machine is installed on a flat surface to a minimum height of 90~cm fitted to support the weight, leaving a clear area of at least 30~cm around the coffee machine.

Hence proceed with installation operations, in compliance with the following steps.

5.1-WATER SYSTEM

Caution! The machine must be supplied with water having a hardness above 8^ degrees.

Caution! It is not possible to use pipes and gaskets already used.

It is advisable to install a water softener for the machine water system.
Ensure that you will be connecting the machine to drinkable water mains.
The connection to the water supply of the machine must be in accordance with the country of destination.
The pressure of water entering the machine must not exceed 0,65Mpa Connect the softener (E) to the water system (A).

N.B. Before connecting the softener to the machine, carry out a washing cycle until the water is absolutely clear, after which you may connect the softener to the machine.

• Connect the drain tray (G) to the drain conduit (B).
• As far as the mains pressure is concerned, if this exceeds 0.5Mpa (5bar), it is advisable to install a balanced pressure reducer for high pressure (a device whereby any mains increase does not affect the output pressure).

Caution! Before proceeding with electric connection, you need to ensure that voltage meets the specifications shown in the EC plate.

Ensure that the electric supply line can bear the machine load (see chapter 4 - Technical Specifications Table).

Provide for an earth connection in compliance with the regulations in force.

In this regard, ensure that the supply cable is efficient, and that it meets the national and European safety standards.

The user is to arrange for machine power supply and protect the line by means of a safety switch (cut-out box) meeting the regulations in force in the country in question.

Connect the supply cable (I) to the electric line by a multipolar switch (D) will have to be arranged for network separation, with a distance between contacts of at least 3 mm.

For voltage change, please refer to the diagram shown on the main switch box.

The yellow/green coloured cable should be COMPULSORILY connected to the premises earthing system.

The machine is equipped with a terminal block under the drain pan

G20

(methane)

G30

(liquefied gas)

G110

(town gas)

The machine is designed to be supplied by methane gas (G20), which means that the gas injector (O) and the gas regulator (N) are set for methane gas.

For GPL gas (G30 liquefied gas) or town gas operation, the gas injector (O) needs to be replaced with the corresponding one attached to the machine (see gas injector table).

Gas burner ignition must be carried out by holding the gas detection valve button pressed (5), to allow inflow of gas into the burner, and by then operating the piezoelectric ignition button (6).

N.B. The detection valve button must remain pressed for a few seconds in order for the thermocouple to start.

Adjust the airflow by means of the specially provided air regulation nut (P); by turning it clockwise the flow decreases, by turning it anticlockwise the flow increases, so as to achieve a blue-coloured flame (avoid high or too oxidising flames, which may damage the boiler).

Wait for the boiler to reach a 1.1 ÷ 1.3 bar operating pressure and for the flame to be reduced to a minimum.

Should you need to set the gas regulator (N), proceed as follows: turn the minimum regulation screw (Q) clockwise to lower the flame and turn it anticlockwise to increase the flame.

When water temperature drops below the minimum set values with the machine running, the flame automatically switches back to the maximum value.

To increase or decrease maximum boiler pressure, operate the pressure regulation screw (R) clockwise to decrease the pressure and anticlockwise to increase it.

The machine is provided with a gas supply tap complying with the safety standards that, in the event of accidental flame extinction, resulting from whatever reason, produces the automatic interruption of gas outflow. In this case, you need to repeat the ignition operation as described above.

The machine may provide both for electrical and gas heating, or else it can be independently heated either electrically or by gas.

When the machine is exclusively gas operated, act on the switches (2-3) to stop the heating element.

6-STARTINGUP

Once the hydraulic, electrical and gas connections have been completed, the machine can be started up.

Open the water system tap (A).

Close the protection switch (D).

Place the main switch (3) on the position: the live machine warning light will switch on (2).

The automatic level indicator will start filling the boiler with water until it automatically reaches an intermediate position between the MIN and the MAX level of the level indicator (23).

Once the automatic water filling operation has been completed, place the main switch (3) on the position for normal power operation, and on the position for maximum power operation, thus supplying voltage to the water-heating element.

Then wait for the machine to reach the 1.1 ÷ 1.3 bar operating pressure, by checking the boiler pressure on the manometer [7].

Should the machine not settle on the indicated values, you will need to set the pressure switch as explained in section 6.1.

When the machine is provided with a gas heating system, after operating the main switch (3), you will need to switch on the gas, by operating the gas valve (5) and pressing the piezoelectric igniter (6) until the gas remains on.

Now check the pressure on the pump manometer (12), by starting a unit with inserted filter-holder, filled with properly ground, dosed and pressed coffee, so as to obtain the actual 8/9 bar operating pressure.

Should you need to reset the pump pressure, you will need to follow the directions listed under section 6.2.

The machine is now ready for use.

If the machine is not provided with an automatic level indicator, after having placed the main switch (3) on the position, press the manual boiler water filling button (9) to fill the boiler with water, and keep it pressed until the water level will have reached an intermediate position between the MIN and the MAX level of the level indicator (23).

Once the water filling operation has been completed, place the main switch (3) on the position for normal power operation or on the position for maximum power operation, thus conveying voltage to the water heating element.

Caution! Absence of water in the boiler while the machine is running causes interruption of the resistance, which will have to be restored by an authorised Assistance Centre.

During start up:

When the boiler pressure control manometer (7) displays a pressure of approximately 0.5 bar, slowly open the steam tap (14-20), by turning it anticlockwise, to discharge the air contained in the boiler, and wait for the steam supply nozzle (11) to start producing steam, before you close it again. Wait for the machine to reach the operating pressure and the correct thermal balance, within 35-45 minutes.

Important! Do not press the hot water supply switch or turn the tap before reaching the correct 1.1 bar operating pressure, indicated by the boiler pressure control manometer (12).

6.1 - PRESSURE SWITCH REGULATION

The pressure switch shown in the picture is designed to maintain the boiler pressure constant, by connecting or disconnecting the electric heating element.

This pressure switch is adjusted during the final testing of the machine on a 1.1÷ 1.3 bar value; however, should the specific case require a different operating pressure, the pressure switch operating range can be changed by operating the regulation screw

(U): by reducing the pressure, you obtain a temperature reduction, whereas by increasing the pressure, the water temperature also increases. The regulation sense is shown in the picture and also on the pressure switch itself.

Pressure varies by approximately 0.1 atm for each complete turn of the screw.

Caution! Disconnect power supply before carrying out this operation.

6.2 - PUMP PRESSURE SETTING

Insert in the brewing unit the filter-holder filled with properly ground, dosed and pressed coffee. Activate the switch or the unit control keyboard (17) and read the pressure on the pump manometer (12).

N.B. The correct pressure is 8/9 bar.

If the pressure displayed by the manometer should not prove correct, operate the pump pressure regulation screw (Z), by turning it clockwise to increase pump pressure or anticlockwise to reduce pressure.

Once regulation is complete, check the pump setting by delivering one or more coffee servings.

Z = Pump pressure regulation screw

Caution! When the machine is new, the filter-holder may not prove aligned (perpendicular to the machine itself) as shown in the picture; this however does not affect proper operation of the machine itself.

After a brief period of use the filter-holder will gradually settle on the correct position

A. Position of the closed filter-holder when the machine is new.
B. Position of the closed filter-holder after the machine has been in use for a brief period.

7-COFFEE PREPARATION

In order to obtain an excellent Espresso coffee, it is important to use a top quality coffee blend, properly roasted and ground; grinding is correct when the coffee delivery time is of 15-18 seconds for one serving and of 30-35 seconds for two servings. Grinding must take place at time of use, in that, once ground, coffee loses its fragrance within a short time; if grinding is too coarse you will obtain light-coloured and week coffee, without froth; if grinding its too fine you will obtain dark coloured and strong coffee, with little froth.

Warm cups contribute to maintaining freshly delivered coffee at the right temperature; it is therefore advisable to place the cups on the spacious cup-holder grid before use (19), which will make it possible to take advantage of the heat emanating from the boiler.

On machines provided with an electric cup-warmer, cups are preheated by pressing the yellow button (1): the button warning light will switch on to signal that the cup-warmer is on. To switch off the cup-warmer, pressed the yellow button (1) again.

Caution! Do not place cloths, felt covers or the like on the cup holder. Once you have placed the filter into the filter-holder (22), fill the filter with the amount of coffee required for 1 or 2 cups (7 gr. - 14 gr.), level off, and press the coffee down with the presser, manually clean the filter edge from any coffee residues and fit the filter-holder into the brewing unit (21) moving it rightward until it is tightly in place.

Place the cups under the spouts and start the brewing by means of the unit control (17).

Once you have obtained the desired amount of coffee, stop delivery by means of the unit control (17), whilst leaving the filter-holder in place.

To prepare additional cups of coffee, remove the filter-holder (22) from the unit, by moving it leftward, empty the coffee grounds into the drawer provided and once again follow the steps listed above.

Caution! We recommend that you do not touch the brewing units or the steam and hot-water nozzles when the machine is running, and that you pay the utmost attention not to place your hands under the units or nozzles during delivery, to avoid possible scalds.

It is advisable to leave the filter-holders, with their own filters and coffee grounds, fitted into the unit throughout your days' work, to ensure the filter-holder always preserves an optimal temperature.

8-BREWING UNIT CONTROL

8.1 - DIAMANTE L MODEL

Machine with lever-operated brewing units.

Coffee is brewed by manually operating the unit lever (10) downwards, up to the point in which it stays in place; as soon as coffee starts pouring out of the filter-holder spouts (22), manually move the lever upwards until it is half-way up, and then release it. The machine does not employ a motor-driven pump and is not equipped with an automatic level indicator for automatic boiler control; this can however be provided for on request.

8.2 - DIAMANTE S MODEL

This is a microswitch-operated model equipped with semiautomatic, continuous delivery brewing units.

Coffee delivery is obtained by operating the brewing unit control handle (17) placed on the panel (4); by moving the handle downwards, the connected microswitch activates the motor-driven pump, which conveys water under pressure to the unit, which, thanks to its internal devices, will allow pre-infusion first and subsequently coffee brewing in a number of different modalities.

Once the desired amount of coffee has been obtained, move the handle (17) upwards, until it reaches its stop position, and press the luminous switch again to stop delivery.

8.3-DIAMANTE SV MODEL

These models are equipped with automatic, continuous delivery.
brewing units with solenoid valve and programmable coffee dosing,
microprocessor-aided sealed digital brewing control, control board
with 4 different coffee-dose selection positions, a stop button for each
brewing unit and a timer-aided hot-water delivery system.

9-COFFEE DOSE PROGRAMMING DIRECTIONS FOR THE DIAMANTE SV MODEL

17. UNIT CONTROL:

Key function:

A. 1 normal cup of coffee.
B. 2 normal cups of coffee.
C. 1 "large" cup of coffee.
D. 2 "large" cups of coffee.
E. Brewing unit stop/continuous delivery.

The ** (E) button is designed for continuous delivery and delivery stop. The machine therefore has a double function:

By pressing the ** (E) button, the equipment is run as a semi-automatic machine.

By pressing the 4 selection buttons, the machine is operated through electronic dosing.

By holding the (E) button pressed for over 10 seconds, the machine will enter the programming phase, as signalled by the low frequency flashing of the LED belonging to the unit on which programming is being carried out.

Release the programming button (the LED will continue to flash) and press the button relating to the unit on which you wish to programme coffee dosing; at this stage delivery will start; once the desired dose has been reached, press any button of the unit concerned to interrupt delivery; the dose will be stored in the memory and the machine will exit the programming phase (the LED will stop flashing and switch off).

1. This operation should be repeated on the remaining selection buttons for the various groups.
2. The same operation needs to be repeated if you wish to increase or decrease the set dose.
3. By programming the first unit to the left, the programming operation will be also accomplished on the various groups.

N.B. The programming phase is signalled by the flashing LED of the unit on which programming is being carried out.

10-COFFEE DELIVERY

To obtain coffee delivery, press the selected button on the brewing unit (17); the LED in the "P" (E) button will switch on, after which coffee delivery will start and will be automatically interrupted once the previously set amount has been reached. Delivery stop will be signalled by the related LED switching off.

Delivery or selection deletion may be interrupted by pressing any key on the brewing unit (17).

The "P" (E) button, besides interrupting supply or aborting selection, is also designed for continuous delivery, which means that the dose is not previously set, but the unit will continue to deliver coffee until the button is pressed again to interrupt delivery from that unit.

If the coffee is too finely ground or too much coffee is placed in the filter, when you press one of the 4 control selectors (A, B, C, D) coffee delivery will not start; after 45 seconds the machine will be automatically blocked and the LED will switch from a fixed to a flashing light state.

To restart the machine, remove the filter-holder and replace the coffee contained in the filter, tpress the ON/OFF switch (1), in order to turn off the machine and subsequently restart it.

N.B. We recommend a maximum delivery of 60 seconds.

N.B. To avoid the automatic block of the machine, if within 10 seconds coffee delivery has not yet started, press one of the selector buttons to cancel the command, replace the coffee contained in the filter and repeat the delivery operation.

10.1 - PRE-INFUSION

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

Our software permits measure configuration so that the relative delivery of the COFFEE measures through volumetric control is preceded by preinfusion.

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.

ENGAGEMENT

Start the machine by pressing the main switch keeping key (A) of unit 1 pressed and wait for the led relative to key (E) to begin flashing. Turn off the machine and then switch it on.

The pre-infusions has been started up.

DEACTIVATION: Start the machine by pressing the main switch keeping key (C) of unit 1 pressed and wait for the led relative to key (E) to begin flashing. Turn off the machine and then switch it on. The pre-infusions has been deactivated.

11 - HOT WATER WITHDRAWAL

Place a container under the hot water delivery nozzle (13), press the jointed handle (16) downwards to allow water delivery; once the desired amount of water has been obtained, the handle will resume the stop position thus interrupting delivery.

N.B. We recommend a maximum delivery of 60 seconds.

12 - PREPARATION OF OTHER DRINKS

12.1 - MILK, CAPPUCCINO AND OTHER HOT DRINKS

Before you heat any drink, carefully let a small amount of steam out of the steam tube (11), by operating the steam tap knob (20) anticlockwise, to eliminate any condensation that may have formed inside the boiler.

Pour the liquid to be prepared into a container, immerse the steam delivery nozzle (11) into the liquid and slowly turn the steam tap knob (14-20) anticlockwise; subsequently open the tap completely, so as to produce a great outflow of steam and bring the liquid to the boil. To obtain a thick milk froth for cappuccino, we recommend you use a high and narrow container, only half-filled with milk.

Immerse the steam delivery nozzle (11) until you touch the bottom of the container and then bring the milk almost to the boil.

Alternatively lift and lower the container with the tap open, until you touch the surface of the milk for a few seconds, until the froth has formed. To make a cappuccino, add the hot whipped milk to hot coffee in the specially designed cup.

12.2-TEA, CAMOMILE

Place a container under the hot water delivery tap (13), press the jointed handle (16) downwards to allow water delivery; once the desired amount of water has been obtained, the handle will resume the stop position thus interrupting delivery. Now add the tea bag or drink sachet required for preparation.

For hygiene purposes, we recommend that in any case you use water from the water system, heated by means of the steam delivery nozzle (11).

13 - MAINTENANCE AND CLEANING OPERATIONS

13.1 - STEAM DELIVERY NOZZLE CLEANING

To avoid altering the taste of the drinks to be heated and to prevent the holes of the end part of the steam delivery nozzles getting clogged, carefully clean the nozzles after each use.

13.2 - DAILY CLEANING OPERATIONS

Rinse the filters and filter-holders in boiling water to avoid scale formation or coffee deposits, and clean the jets of the delivery units.

14 - WEEKLY CLEANING OPERATIONS

14.1-BREWING UNIT AND JET CLEANING

Remove the filter-holder from the brewing unit.

Position the provided seal inside the filter, pour a spoonful of coffee-machine detergent powder and fit the filter holder (22) into the brewing unit to be cleaned (21).

Operate the brewing unit by means of the unit control (17) and interrupt delivery after approximately 4-5 seconds.

Alternatively operate and interrupt delivery for approximately one minute, so as to allow removal of coffee and scale deposits.

Remove the seal and operate the delivery system several times to rinse the unit. Deliver a few servings of coffee so as to eliminate any unpleasant taste from the jets and from the brewing unit.

After a long period of hot water stagnation within the conduits, let water briefly flow vertically so as to remove any deposits.

14.2 - FILTER AND FILTER-HOLDER CLEANING

Frequently check the filter holes to remove any coffee deposits. Prepare about a litre of boiling water with four teaspoons of coffeemachine detergent in a suitable container, and immerse in this solution the filters and filter-holders for 20-30 minutes; then rinse thoroughly under running water.

14.3 - DRAIN TRAY CLEANING

Remove the drain try grid (25) and pull out the drain tray (24) in order to clean it from coffee powder residues.

14.4-CASING CLEANING

Use a damp, non abrasive cloth, without alcohol or solvents, to avoid damaging the sides, the base and any painted parts.

Important! The machine can not be immerse in water and can not be cleaned with jets' water.

If, during delivery, the coffee drips out of the edges of the filter-holder (G), this may be caused by the obstruction of the filter-holder delivery hole, in which case the hole needs to be cleaned; if the problem persists or, if when fitting the filter-holder into the brewing unit it significantly moves beyond the unit centre, the group gasket needs replacing (D).

15.1 - DIAMANTE S - SV MODEL

For the replacement, it is necessary to lever with a screwdriver for the removal of the seal (B) and the shower (A). After removing the seal and hand shower, properly clean the seat before reassembling the new parts.

15.2-CREMA L MODEL

For the replacement, it is necessary to lever with a screwdriver for the removal of the seal (B) and the shower (A). After removing the seal and hand shower, properly clean the seat before reassembling the new parts.

16 - BOILER WATER REPLACEMENT

It is essential to replace the water contained in the boiler every 15-20 days, in order to eliminate the iron bacteria and the build-up of various residues due to water stagnation.

Turn off the main switch (1), remove the drain basin grid (25) and pull out the lower drain basin (24).

Open the drain tap placed under the level glass (with the boiler under pressure) and let the water flow out of the boiler comple

tely. Close the tap again and repeat the start-up procedures by following the steps outlined in the related section of this manual.

17 - USE OF THE SOFTENER

Calcium and magnesium contained in the water circulating inside the boiler and brewing unit circuits damage the machine. The softener dissolves the calcium and magnesium, which settle on the resins therein contained.

To prevent the build-up of deposits from saturating the resins, thus limiting their functions, these need to be regenerated at regular intervals according to the following criteria:

• 8 litre softener for 40 French degree HARDness water

• up to 400 cups of coffee/day, every 10 days

• up to 800 cups of coffee/day, every 5 days

• up to 1000 cups of coffee/day, every 3 days

• 12 litre softener, for 40 French degree HARDness water

• up to 500 cups of coffee/day, every 15 days

• up to 1000 cups of coffee/day, every 7 days
  up to 1500 cups of coffee/day, every 5 days
• up to 2000 cups of coffee/day, every 3 days.

Failure to comply with the above regeneration timings will prejudice the thermal and mechanical functions of the machine and the taste of the coffee, owing to the formation of scale.

For regeneration, proceed as follows:

Place an empty container, having a capacity of at least two litres, under pipe (e), turn the (c) and (d) handles to the right, unscrew the (g) lid and wait for the water to fully flow out of pipe (e). Introduce 1.5 Kg. of cooking salt for the 8 litre model or 2 Kg. of salt for the 12 litre model, place the lid back in place and move the (c) handle from right to left; let the salted water flow out of the (f) pipe and wait until the water has become fresh again (the cycle takes approximately 90 minutes).

a - Water inlet.
b - Water outlet.
c - Inlet tap.
d- Outlet tap.
e -Vacuum pipe.
f - Regeneration pipe.
g-Lidknob.

Now move the (d) handle from right to left.

During regeneration, do not use the machine; for machines equipped with automatic level indicator it is advisable to cut off the pump power supply, to prevent no-load operation.

Before connecting the softener to the machine, wash the resins, by establishing a connection to the water mains and letting water run for five minutes.

N.B. The above mentioned directions relate to the softener shown in the pictures; if your equipment differs, follows the directions attached to softener in question.

18 - MACHINE DEMOLITION

Should you decide to no longer employ the machine, owing to wear or to other reasons, we recommend that, once you have removed the plug from the socket, you deactivate it by cutting off the supply cable. As regards the demolition procedure, we recommend you separate the various parts of the machine, depending on their nature (pla-stic, metal, etc.). Hence employ specialised firms for the disposal of the various parts.
