1. MACHINE INSTALLATION
1.1 Receiving the product
After unpacking, make sure the appliance has not been damaged due to transport.
Otherwise, report the anomaly to the dealer. For disposal of the packing, see chap. 17.
1.2 Water connection
Connect the machine water supply to an on/off valve that can rapidly and completely
shut off the water inflow.
Make sure the water supply pressure is within the values given in table 1.
Ifitisbelow 200 kPadynamicpressure,for optimalmachineoperationa pressure increase
pump must be installed (the machine can be supplied with such a pump by request).
If the supply pressure is higher than 4 bar (400 KPa), installation of a pressure reducer
is recommended.
A water softener must be installed for waters with average hardness above 10 °f.
Toensure optimum performance,the water supply temperature range must come within
the values given in table 1.
Thiswillensure cleaner dishes/articlesandlonger machinelife.Every machine issupplied
with a rubber hose for water filling with 3/4"F threaded connection.
It is advisable to connect the hose to a water supply not above 55° C, if connected to the
hot water.
Connect the drain hose, supplied with the machine, to the drain union in such a way that
waterflowsfreely (therefore ensuringaminimum slope). Ifthewater cannot bedischarged
to a level below the machine drain, it is advisable to install a drain pump suppliable on
request.
The drain hose must always be connected to a trap to prevent the return of odours from
the system.
1.3 Electrical connection
Electrical connection must be carried out in compliance with current standards.
Make sure the line voltage matches that given on the machine dataplate. An omnipolar
thermal magnetic switch with contact breaking distance of at least 3 mm and adequate
for the absorption must be installed (the machine must be turned off with this switch).
The switch must be used only and exclusively for this use and installed in the
immediate vicinity.
Ensure that the system has an efficient earth.
On the back of the machine there is also a terminal marked by a symbol (see fig.1) used
for the equipotential connection between different appliances. The special dataplate
gives the max. power value in watts (W) and amperes (A), for dimensioning of the line,
cable and switches.

N.B.: for machines with 400Vac3N, H05RN-F or H07RN-F type cables
must be used, or replace them with others conforming to the standards
in the country where the dishwasher is installed. The dealer/importer/
installer must adapt the power cable insulation class according to the
work environment, in conformity with current Technical Standards.
In machines with three-phase pump, pay attention to correct pump rotation.
Start up the dishwasher and carry out any calibration of the detersive dispenser in the
following way:
1) Turn the wall switch on and open the water cock.
2) Switch the dishwasher on, pressing the key (B) (see chap. 2). The reletive green LED
lights up.
3) The machine starts to fill with water (important: do not open the door).
4) At the end of boiler filling, rinsing starts, to complete the tank filling. After filling, the
dishwasher starts heating the boiler and tank.
5) The machine is ready for washing.
N.B.: If the cock is closed or the filling time is too long, the dishwasher may go on tank
filling time-out (programming parameter (B)) indicating fault code (3).
1.4 Rinse aid dispenser operation
Operation:it utilizes thecombined difference inpressure resultingfrom the start/stopof
the wash pump and the rinse pressure.
Water connection:
1) connect the dispenser by its hose holder fitting (A) to the pump, by means of the
rubber hose installed in the machine (pump pressure).
2) Connect the black rubber tube by its delivery connection (B) to the union located near
the boiler (injector).
3) Ensure insertion of the green product-suction tube in the special connection (C) and
the filter and ballast in the rinse aid tank.
Priming: to carry out priming, start the machine and do a few complete wash cycles or
press the adjustment screw D during the wash cycle and open and close the door
combined with the pressure of pin D. This system speeds up reinstatement.
Adjustment: with every rinse the dispenser draws a quantity of rinse aid adjustable
from 0 to 4 cm3equivalent to a length of 0 to 30 cm drawn in the tube.
Min. delivery is obtained by screwing the adjustment screw D (clockwise) all the way,
whereasmax. delivery is obtained by unscrewing the adjustmentscrew approx. 20 turns
(anticlockwise).
For the right amount of product see the paragraph “Rinse aid use” (chap. 15.2).
N.B.: for every turn of the screw the amount of rinse aid drawn in the tube varies by 1.6
cm, equal to 0.2 cm³/turn (approx. 0.21g/turn with rinse aid density of 1.05 g/cm³).
The rinse aid dispenser cannot work correctly if the difference in level between the
bottom of the machine and the tank is more than 80 cm.

1.5 Detersive dispenser installation
Electrical connection:
See the wiring diagram attached to the dishwasher and follow the instructions on the
diagram.
Water connection:
a) A Ø 12 hole must be made in the back of the dishwasher. In some dishwashers the
hole is already available, and closed with a plastic plug. Remove the plug from the hole
and fit the delivery connection.
b) Otherwise, make a hole of the same diameter as your injector in
therear part ofthe tank (see fig. 4); this operation must be carried out
by Technical Assistance.
The hole must be made above the water level.
Important: make the hole in a place away from the overflow, in order
to avoid the immediate spilling of detersive, and fix the dispenser
upright with the hose holders turned downwards, taking care not to
position the injector over live parts or where it interferes with filters.
c) Correctly install the injector (C), using the appropriate seals.
d) Connect the suction tube to the dispenser suction connection (see
fig. 4 - point A).
e) Connect the delivery tube to the other connection of the dispenser
and the delivery union (see fig. 4 - point B).
f) Insert the tube with filter in the detersive tank.
g) Prime the detersive and proceed with the dosage phase.
Dosage:
Thedetersive dispenser deliverycan beadjusted bydirectly operating
with a screwdriver as shown in fig. 5.

5. TEMPERATURE ADJUSTMENT
Boilertemperature adjustment alwayshas priority overthat of the tank, and the tank and
boiler cannot be switched on at the same time.
Toreducethe electrical stressofthe loadsandoutput relay contacts,delaysand minimum
activation times are entered.
The temperature adjustment outputs are kept off in the following cases:
• if the temperatures measured are below 5°C;
• if there is a fault;
• if there is no water.
During wash pump operation the tank heating element does not work.
6. ENERGY-SAVING FUNCTION
This function is activated by a jumper (see fig. 8).
The energy-saving function only acts on the boiler temperature adjustment and when
the machine is not in operating cycle.
If activated, the temperature setting is decreased, with respect to that entered, by the
programmed amount.
During operation the temperature setting returns to that entered.
7. THERMO-STOP FUNCTION
This function is activated by a jumper (see fig. 9).
During the cycle, at the end of wash time, the next phases are carried out after the boiler
has reached the set temperature.
If this function is deactivated the machine goes to the subsequent wash cycle phases,
whatever the boiler te
8. WATER FILLING
Water filling is controlled by a pressure switch.
Filling occurs by means of the solenoid valve used for the rinse and when the pressure
switch contact is open.
Thereis a maximumwater filling time, settable in programming, after which the machine
stops if the level is not reached, displaying the message (Er) followed by the relevant
fault code.
8.1 Conditions preventing water filling
Water filling is not carried out if the Atmospheric pressure boiler version is being used
and boiler filling is under way.
9. BOILER FILLING (Atmospheric pressure boiler version only)
Boiler water filling is controlled by a pressure switch.
There is a maximum boiler water filling time, settable in programming, after which the
machine stops if the level is not reached, displaying the message (All) followed by the
relative fault code.
9.1 Conditions that zero-set boiler filling.
The boiler filling cycle is cancelled in the following cases:
• if the card is switched off.
• during the hot rinse; boiler filling will resume at the end of the hot rinse.
10. WATER HARDNESS SETTING ON DISHWASHERS WITH
OPTIONAL REGENERATION
See table 2 - parameter (C).

be ahead of a trap.
11.1 Manual draining
Press the key (D) after removing the overflow and the pump operates for the time set in
programming.
The drain pump is activated in the following way:
• activation of a 5sec delay at start;
• activation of the drain pump for the time set in programming, up to the level indicated
by the pressure switch.
Note: afterthe set timeand if thelevel of thepressure switch isat minimum the machine
goes on Stand-By, otherwise after about 3min. it goes on water drain alarm (alarms 8 -
table 3 - chap. 19.2).
The card must not be activate during manual draining in standard version and clean
water.
11.2 Automatic draining
Draining is activated automatically in the following situations:
• at the end of the wash cycle (only if in clean water function mode);
• after 5sec from activation of hot rinse;
• when a cooling cycle in boiler temperature alarm is activated.
Activation of the drain pump always occurs in the following way:
For function mode with standard version:
• activation of a 5sec delay at start;
If the cold rinse is enabled:
• output switch-off after 10sec from the end of cold rinse.
If the cold rinse is not enabled:
• output switch-off after 10sec from the end of hot rinse.
For the function mode with (CLEAN WATER):
• drain pump activation
• wait for reaching of min. level (level pressure switch opening);
• pump activation for a time equal to:
(“min. level reaching time” + “programmed drain time”).
Drain pump operation occurs even if the door is opened or an alarm is present.

With the machine activated (green LED on), press the (Start) button for less than 1
second and release it to activate wash cycle start.
Keep the button pressed for more than 5sec to select the required wash cycle.
After the type of cycle has been selected, the relevant LED stays on.
14.1 Clean water function cycle
This working cycle is only for machines clean water version.
The cycle sequence is as follows:
• lighting of selected cycle LED;
• activation of wash pump for the time set in programming;
Note: the wash time can increased if the thermostop function is activated, which waits
for the boiler temperature to reach the set temperature before the cycle goes to the next
phases.
• at the end of wash time the pump is switched off and tank emptying is activated;
• after emptying the tank it is filled (rinse);

14.2 Standard function cycle
The cycle sequence is as follows:
• lighting of selected cycle LED;
• activation of wash pump for the time set in programming;
Note: the wash time can be increased if the thermostop function is activated, which
waits for the boiler temperature to reach the set temperature before the cycle goes to
the next phases.
• at the end of wash the cycle the pump is switched off and a 3sec. pause is
activated.
If the parameter (Flowswitch) is enabled:
• at the end of the pause the hot rinse for the quantity of water delivered useful for the
rinse set in programming, is activated.
If the parameter (Flowswitch) is not enabled:
• at the end of the pause the hot rinse is activated for 15sec.
If the cold rinse is enabled:
• at the end of hot rinse the cold rinse is activated for 10sec.
• after5sec from the start of hot rinsethe drain pumpis activated and then deactivated
10sec after the end of cold rinse, even if the door is opened (only if the parameter (Drain
Pump) is enabled).
If the cold rinse is not enabled:
• after5sec from the start of hot rinsethe drain pumpis activated and then deactivated
10sec after the end of hot rinse, even if the door is opened (only if the programming
parameter (Drain Pump) is enabled).
• atthe end of hot or cold rinse(if enabled)the cycle finishes, signalled bythe message
(End).
N.B: Another cycle cannot be restarted:
• if the door is not opened.
• if the (Stop) button is not pressed.
• if the (Off) button is not pressed.
14.3 Conditions that zero-set the wash
The cycle is cancelled, going to stop conditions, in the following cases:
• in case of a fault.
• if the (Stop) button is pressed for more than 2sec.
• if the (Off) button is pressed.
14.4 Conditions preventing the start of washing
The cycle is inhibited in the following cases:
• if the door is open; in this situation the message (Door) is displayed for 4sec:
• if there is no water; in this situation the message (H2O) will be displayed for 4sec (in
version with flowswitch):
• on alarm;
• during tank filling.
14.5 Conditions that block the wash cycle
The cycle times are blocked in the following cases:
• if the door is opened;
• if there is no water (in version with flowswitch).

15.OPERATION
• Insert the overflow pipe in the special seat inside the tank (standard version only).
Make sure all the filters are properly fitted in their seats. The filters must be cleaned
every 30-40 wash cycles and whenever necessary.
•Do not operate the machine without filters and in particular the pump suction
filters).
• Close the door.
Openthe water cock, turn the main wall switch on and start the machinepressing the
key (B) (see fig. 6). The green LED lights up. After a few seconds the tank filling phase
starts.
• After filling, the machine automatically starts the heating phase.
• The machine will be ready for washing only when the boiler and tank thermometers
indicatethat the required temperatures havebeen reached, whichare 80-85°C for boiler
and 50-55°C for the tank.
• Insert the special green rinse aid dispenser tube in the liquid rinse aid container (the
transparent tube must only be inserted in the detergent container) and check that the
quantity is sufficient for the daily requirement.
• Insert the basket with dishes or various articles to be washed and close the door.
• For cycle choice, select the wash cycle (1, 2, 3, ∞)∞)
∞)∞)
∞) with the key (A) (see fig. 6)
keeping it pressed for more than 5 seconds and release when the LED of the required
cycle lights up. The green LED of the selected cycle lights up (1, 2, 3, ∞∞
∞∞
∞).
• Start the cycle by pressing the key (A) for not more than 1sec (see fig. 6). Starting of
the cycle is signalled by the indicator of the selected cycle flashing. At the end of the
cycle the indicator stops flashing and the message (END) appears on the display.
• The machine is ready for a new wash.
It is advisable to change the tank water, by means of another filling, at least every 40-50
washes or twice a day.
N.B.: the machine does not accept other cycles until the door is opened or the key (A) is
pressed twice (see fig. 6).
The cycles (1, 2, 3, ∞∞
∞∞
∞) are factory-set with times of 60 - 120 - 180 - 300 seconds and can
be changed with programming by the installer.
Clean the machine at the end of the day (see chap. 16 Maintenance).
Switch the machine off and close the water cock.
15.1 Detersive use
It must be of the NON-FOAMING type and suitable for industrial dishwashers.
The use of liquid detergents is recommended.
The detersive must be introduced in the tank.
Theamount is recommendedby the manufacturersaccording to the water hardness. By
request the dishwasher can be equipped with an electric detersive dispenser (always
recommended).
1cm of product drawn in the transparent tube corresponds to approx. 0.15g. A correct
amount of detergent is very important for efficient washing.
15.2 Rinse aid use
Themachine comesstandard witha rinseaid dispenser.The machinedraws theproduct
on its own. The amount can be varied by operating the dispenser micrometrical screw.
Turn clockwise to increase the amount and anticlockwise to decrease it.
An amount of 2-5cm of product measurable on the suction tube is recommended. 1cm
of product drawn in the green tube corresponds to approx. 0.13g. A correct amount of
rinse aid is very important for quick drying and sparkling dishes.
N.B.: too much product, or foam, reduces the efficiency of the wash pump.
