4 INSTALLER INSTRUCTIONS

The installation must be made by a qualified person, carefully observing all the manufacturer's
indications. After having unpacked the dishwasher, inspect it to see if it has been damaged during
shipment. If there is any suspect evidence, consult a service representative. All the packing materials

(bags - Styrofoam - nails - etc.) must not be left where they can cause harm to persons, especially
children. When installing, made certain the unit is perfectly level - adjusting the feet as required as this wi ll
ensure correct operation.

When locating the machine, allow plenty of free space around it to permit easy access and operation by
maintenance personnel. Remove the rear panel to permit making the water connections. Mount any shelves,
benches or roller units that are to be mounted to the machine inlets and outlets, and then make the end-travel
micro switch electrical connections at the terminals located inside the machine. The machine must be fitted
with detergent and brightening dosing equipment, which will be furnished and installed by the firm that supplies
the cleaning products. The electrical terminal strip for making connections to the dosing units is located inside
the electrical box.

The terminals (B) and (D) on the terminal strip are for the dosing connections: (B) for the brightener and (D) for
the detergent. Do not pour detergent directly into the tubs; this will cause dark marks to appear on their
surfaces. Only use antifoaming detergent. The brightening equipment (B) operates on 24V, and the detergent
equipment (D) operates on the mains voltage. The machine equipped with a IPX1 degree of protection and
should therefore not be washed using direct jets of water.

4.1 WATER CONNECTIONS:

The machine has a filter whose inlet, install a maintenance and safety valve in an easily accessible position
upstream. The water temperature should be between 50°and 55°C; the pressure should be between 200/400
kPa and the water hardness should be between 7° and 12° French.
Hold down the button located next to the thermostat and fill the boiler with water. When the boiler is
completely full, water will issue from the rinsing nozzles. Now set the thermostat to 90°C.
Be careful here, because if you let it get to high you could burn out the electrical.
With machines that have a steam-condenser and heat energy-recovery capability, cold water must be feeding at
a temperature of between 10° and 15°C.

4.2 DRAIN WATER:

Install a floor-level discharging siphon connected to the discharge drain. If no siphon is provided, install one soas
to avoid fumes. Make sure that the discharge tube can resist a temperature of 70°C and no kinks in it.

4.3 STEAM FEEDING:

Connect to the machine fittings as shown in the installation drawing. Install quick-closing and shit-off valves to
make the equipment independent from the main line. The steam should be supplied , saturated and dry, at
pressures ranging between a minimum of 0.5 bar (50Kpa-110.8°C) and a maximum of 0.8 bar (80Kpa-110.8°C)

4.4 STEAM DRAIN:

The condensed steam discharge line to the recovery system has to have an adequate slope to provide positive
evacuation. Install a recycling pump if required. This is only for steam heated machine. A maintenance quick
closing valve should be installed in parallel with the condensate discharge, so as to be able to deviate the
condensate to the sewer.

Caution: make sure that the supply and drain tubes are not bent, restricted or crushed after
installation.

4.5 Electrical connection

The dishwasher’s electrical connection, and that of eventual supplementary apparatus, is to be
entrusted to authorized and qualified personnel, with respect to the norms in vigor; the technical
regulations for the connections are also to be observed. The total power installed is given upon the
apparatus’ technical data label.Other apparatus must not be protected together with the dishwasher.
The user must provide for the installation, according to the norms in vigor, of a main electrical power
switch and of a differential switch compatible with the machine’s characteristics.
These switches must be installed near the dishwasher, be easily accessible after installation and
guarantee complete disconnection from the electrical supply in category III over voltage conditions.

7 MAINTENANCE AND CLEANING

Although special, programmed maintenance is not required, we recommend having the dishwasher checked by a
specialized technician twice a year.
Note: intentional damage or that derived from carelessness, negligence, lack of respect for the regulations,
instructions and norms or erred connections are not to be considered the responsibility of the manufacturer.

7.1 Daily cleaning

The dishwasher has an IPX1 protection rating, but the use of direct streams of water for its cleaning is
forbidden.

CLEANING OF THE FILTER DURING THE DAY

In case of particularly heavy usage it is recommended to perform a cleaning of the filter every 30-40 wash cycles
in order to maintain the machine in operative condition; Use “partia l tank draini ng” in order t o perform th ese
cleanings.

Open the door and remove the "overflow" tube to drain the tube. When the tube
is empty, clean it thoroughly.
Remove and clean the filters. With the steam condensate machines, remove and
clean the filter. In order to avoid burns and skin irritation, do not put naked
hands in hot cleaning water with detergent. If you happen to do so, rinse your
hands
off immediately under lots of running water. When you have completed these
operations, put all the components back in their original locations and leave the
door open in order to avoid unpleasant odours forming. Do not use corrosive
substances,
such as calcium hypochlorite (chlorox,etc.), acids (such as hypochloric acid) or
steel wool or steel brushes to clean the inside and outside parts of the machine.

In order to keep the machine in good running order, any hard-water deposits

(calcium and magnesium carbonates, etc.) should be periodically

removed by qualified professionals.
In order to avoid drops or vapors damaging the steel surfaces, do not even use the above-indicated products for
the cleaning of the flooring beneath or around the dishwasher.

7.2 Periodic checks

Disassemble the wash and rinse arms (lower and up per).
Clean the holes and the nozzles under a stream of clean water. Do not use utensils which could cause damage.
Carefully reassemble the wash/rinse arms.

Clean the outside of the machine with neutral soap and a damp cloth. Rinse and dry with care.

7.3 Prolonged disuse

If the use of the dishwasher is not foreseen for a relatively long period of time, it is necessary to drain the
detergent and rinse-aid dispenser in order to avoid crystallization and pump damage: Remove the suction

tubes from the detergent and rinse-aid containers and emerge them in a container filled with clean water.
Perform a few wash cycles and drain the machine completely.

11

Finally, turn off the main switch and close the water supply faucet. The detergent and rinse-aid suction tubes
will be placed back in the containers when the machine is ready to be put back in use, taking care so as not to

invert the tubes
Do not leave the device on, inactive and unutilized for long periods of time.
