disposal centre. The plastic components suitable for recycling are marked as follows: PE polyethylene:
external packaging film, bag containing the instructions, protective bags. PP polypropylene: straps. PS
expanded polystyrene: corner guards, top of packaging. Wooden and cardboard components can be
disposed of in accordance with the relevant regulations. When the product is decommissioned it must
not be dumped in the environment; it must be disposed of in accordance with the relevant regulations.
All metal parts are in stainless steel and can be removed. The plastic parts are marked with the symbol
identifying the material used and must be disposed of in accordance with the relevant regulations When
the product is decommissioned it must not be dumped in the environment; it must be disposed of in
accordance with the relevant regulations.
POSITIONING:
Caution: the indoor system and premises in which equipment for institutions is installed

4 INSTRUCTIONS FOR TECHNICAL STAFF
4.1 Plumbing hookup
Water supply and drain connection
The water pipelines and electricity supply cable lead out of the bottom
right-hand corner of the appliance. Connect the water intake hose to a
connector with ¾” gas threaded fitting, fitting the filter A provided (in
models with aquastop, the filter and ring-nut form a single unit).
The connection to the water mains must only be made with new hoses;
the use of old or worn hoses is not permitted.
FOR MODELS WITH A WATER SOFTENER
AN ‘APPROVED’ DOUBLE CHECK VALVE OR SOME OTHER NO LESS EFFECTIVE DEVICE PROVIDING
BACKFLOW PREVENTION PROTECTION TO AT LEAST FLUID CATEGORY TWO SHALL BE FITTED AT THE
POINT OF CONNECTION BETWEEN THE WATER SUPPLY AND THE FITTING OR APPLIANCE.
FOR MODELS WITHOUT A WATER SOFTENER
AN ‘APPROVED’ SINGLE CHECK VALVE OR SOME OTHER NO LESS EFFECTIVE DEVICE PROVIDING
BACKFLOW PREVENTION PROTECTION TO AT LEAST FLUID CATEGORY TWO SHALL BE FITTED AT THE
POINT OF CONNECTION BETWEEN THE WATER SUPPLY AND THE FITTING OR APPLIANCE.
The dynamic water supply pressure must be between 1 and 6 bar; if it is higher, installation of a
pressure reducer is necessary.
It is essential to fit a main stop tap on the water intake deliver pipeline; the tap must be accessible
after installation of the appliance, so do not install it behind the dishwasher. The stated cycle duration
applies to appliances supplied with hot water >50°C<60°C. If the dishwasher is supplied with cold
water, the cycle duration might increase depending on the intake water temperature. The dishwasher
is fitted with a drain pump and can operate with drain connections on the floor or wall.
Drainage:
The dishwasher is fitted with a drain pump and can operate
with drain connections on the floor or wall.
Warning! Maximum height of drain hose!
Caution: make sure that the intake and drain hoses
are not bent, constricted or crushed after
installation.
7
If the appliance is fitted with a water softener, the drain must not be connected to a siphon
with valve ! water softener will be out of use
Refer to the connection diagram for the maximum permitted height of wall drains – (see TECHNICAL
DATA)
Caution: make sure that the intake and drain hoses are not bent, constricted or crushed
after installation.
4.2 Electrical connection
The dishwasher and any additional equipment must be connected to the electrical
system by authorised, skilled staff, in accordance with the relevant regulations; also
comply with the technical instructions for the connection.
The total rated power is stated on the appliance’s technical data plate.
The electrical protection devices fitted for the dishwasher must serve this appliance only.
The user must have a master switch and a differential safety breaker, with rating
suitable for the appliance’s characteristics, installed on the electricity supply line in
accordance with the relevant regulations.
These switches must be installed close to the dishwasher, be easily accessible after
installation, and provide complete disconnection from the electrical mains in overvoltage
class III conditions.
Warning !!!
The dishwasher is always powered up unless the master switch is turned off.
Connect the appliance to the user’s earth system. The terminal for the connection is in
the bottom right-hand corner of the appliance.
The earth wire (PE) is yellow-green in colour, the neutral wire (N) is blue and the live wires
(L1, L2, L3) are black, grey and brown.
In the event of single-phase connection (230V-1N~), the connection to the electrical
mains must be made using a cable with plug compliant with the relevant regulations.
THE POWER SUPPLY CABLE, AS PROVIDED, MUST BE REPLACED BY THE
MANUFACTURER OR AN AUTHORIZED SERVICE CENTER IN COMPLIANCE WITH THE
SPECIFICATIONS PROVIDED ON ELECTRICAL DIAGRAM SUPPLIED IN THE MACHINE IN
ORDER TO PREVENT ALL RISKS.

5 FIRST START-UP
First start-up
The electrical protection system must undergo a functional test before the appliance is put into
operation.
The appliance must be installed and/or inspected by qualified staff, who will start it up for the first
time and provide the relevant operating instructions.
Preparing for use (important)
The rinse aid dispenser is fitted on all models, the detergent dispenser only on some.
If both dispensers are present put the external detergent and rinse aid containers in place and insert
the respective intake hoses on the rear of the appliance into them.
Red hose: detergent
blue hose: rinse aid
note: It takes about 10-15 wash cycles before they arrive in detergent and rinse tank and boiler.
Before inserting the hoses into the containers, fit the weights
(needed to ensure that they always draw in liquid from the bottoms
of the containers) and the filters onto their ends as shown.
If the detergent dispenser is not factory-fitted, it can be retrofitted
after ordering the relative kit.
As an alternative an external dispenser can be fitted, making the electrical connection by means of an
H05 RN-F 2x0.5 mm electrical cable, which can be laid along the route shown in the TECHNICAL DATA
diagram. The electrical connection must be made in accordance with the electrical system diagram
supplied with the dishwasher, disconnecting the internal dispenser, if any, and making the connection
to the external unit.
The dispenser must operate on 230V/50 Hz with maximum power absorption of 15 W.
Connect to the detergent dispenser outside the dishwasher using the red hose mentioned above.
As an alternative an external dispenser can be fitted, making the electrical connection by means of an
H05 RN-F 2x0.5 mm electrical cable, which can be laid along the route shown in the TECHNICAL DATA
diagram and connected as shown in the wiring diagram supplied with the dishwasher.
The dispenser must operate on 230V/50 Hz with maximum power absorption of 15 W.
Connect to the detergent dispenser outside the dishwasher using the red hose mentioned above.
IMPORTANT:
Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out
the peristaltic pumps by placing the external intake pipes in water for a few cycles.
Always use only products specifically recommended for use in a dishwasher.
Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on
the appliance’s water system.
The internal pipes of the detergent and rinse aid pumps should be replaced by the After-Sales
Service every 12 months or 15,000 wash cycles and operation of the diaphragm rinse aid pump
should be checked.
