3.6 Filling the water heater

a
ATTENTION
Do not connect the water heater
to a power supply before it is full
as this could damage the heating
element.
– Open the shut-off valve to allow water to
enter the water heater.
– Open a hot water tap (bath, sink, etc.)
to allow the air within the water heater
and the system to be released. The water
heater will be full when the hot water tap
opened stops releasing air and starts re-
leasing water.
– Check that there are no water leaks from
any of the system's connections.
m
WARNING
Only after these steps may it be
connected to a power supply.

WARNING
In case of water with hardness >
20º TH (where 1ºTH = French de-
gree = 10 mg CaCo3 / l), a water
softener must be installed to re-
duce fouling inside the water heat-
er and preserve the efficiency of
the electric heating element and
the water safety unit.

3.7 Connecting to a power supply

Make sure that the mains' power matches
that indicated on the appliance and that the
system is compatible with the wattage of
the electric water heater's heating element.
A double-pole switch must be used in ac-
cordance with EN standards (contact open
at least 3 mm and preferably with fuses) to
disconnect the appliance from the power
supply. The connection must be made by
removing the electrical protection cap and
inserting the brown and blue cables in the
terminals of the thermostat L (L1 and L2).
The water heater must also be earthed us-
ing the yellow/green cable as shown in the
following electrical wiring diagram ("Fig.
21").
