2.2 Positioning
•
•
•
•
•
•
Check that there are no objects or materials in the installation area which may
be damaged by the steam emitted by the appliance during operation, or if there
are, make sure they are properly protected.
Before positioning the appliance, set up the electrical power supply, water
supply and drain connections
The floor or build-in unit must be rated to support the weight of the appliance
To ensure that it is stable, level the appliance with its four feet.
The appliance is intended for fixed installation only; any other approaches must
be agreed with and approved by the manufacturer.
Remove the protective film from its body panels before operating the
dishwasher.
2.3 Electrical connection
•
•
•
•
•
•
•
•
•
The power supply must be fitted with a omnipolar circuit breaker (master power
switch) to break all contacts including neutral, with a contact gap of at least 3
mm and thermal cutout or fuses, which must be set or rated to the power
indicated on the machine's nameplate.
The master power switch must be fitted to the power line in the vicinity of the
installation and may be connected to only one machine at a time.
The mains voltage and frequency must match the nameplate ratings.
The installation must include a grounding system conforming with established
electrical safety legislation, to protect the operator and the appliance itself
The power line, which must be H07RN-F unit, must not be stretched or crushed during normal
operation or maintenance.
The appliance must also be connected to an equipotential system with the screw marked with the
symbol.
The equipotential cable must have a cross section of 10 mm².
Respect the polarities indicated in the wiring diagram.
For further information, refer to the wiring diagram.
Do not use multi-sockets, adapters, cables of an inadequate cross section or type or
with extensions not conforming to established electrical installation regulations.

INSTRUCTION MANUAL FOR DISHWASHERS
UK
2.4 Water circuit hookup
The appliance must be connected to its water supply with a flexible hose. A
shut off valve (cock) must be installed between the water supply line and
the appliance's solenoid valve. The cock must be close to the appliance.
•
•
•
The water supply, temperature and pressure must be compatible with the ratings on the
machine's nameplate.
If the hardness of the water is greater than 14 F (8 dH), we recommend using an internal water
softener (available on request). If the hardness of the water is greater than 35 F (19.5 dH), install
and external water softener upline of the solenoid valve.
If the water has a very high residual concentration of high conductivity minerals, we recommend
installing a demineralisation system.
2.5 Connection to the drain line
•
•
Free drain
•
Max.
1m
•
•
•
The drain line must consist of a free drain sump with siphon suited to
the flow capacity of the drain hose supplied with the appliance. The
hose must be able to reach the sump without stretching, restriction,
folding, crushing, pressing or forcing in any way.
The tub drains under gravity, so the drain sump must be lower than the
machine's base.
if the drain is not lower than the base of the appliance, you can use the
version with drain pump (available on request).
In this case, the drain connection may be no higher than 1 m.
Always check that the drain works properly and is not blocked.
Any other solution must be approved by the manufacturer in advance.
With pump (available on request)
2.6 Rinse aid and detergent
•
•
•
•
•
The rinse aid and detergent are dispensed by the machine's integral dispenser (depending on
model).
The dose is set by the installer in relation to the hardness of the water, and he also calibrates the
dispensers themselves.
Before calibrating them, fill the dispenser supply tubes with their respective product.
The units are calibrated with the adjuster screws, or directly with the control panel (as applicable).
The level of fluid in the container must be sufficient for priming; do not allow it to drain completely
or top it up with corrosive or impure product.
NEVER use CHLORINE or HYPOCHLORITE based detergents.
We recommend installing an automatic detergent dispenser.
