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 shown on the
technical data plate on the machine.
Make sure that the water supply flow rate is no less than 20 l/min
If the water hardness is greater than 14 °f (8 °dH), we recommend using an internal water softener.
If the water hardness is greater than 35 °f (19.5 °dH), install an external water softener upline of
the solenoid valve
For machines without water softener: if the water hardness is greater than 14 °f (8 °dH), install an
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.
Machines intended for use with desalinated water or in any case with high sodium chloride
concentration must be ordered specifically, as they require specific construction materials
Do not supply fully demineralised water to machines with a heat recovery unit with batteries with
copper pipes. In this case, request the version with batteries with stainless steel pipes.
Free drain
3.5
Connection to the drain line
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.
Max.
1 m
With pump (available on request)
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.
3.6
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.
