to withstand these temperatures should not be used.
Furthermore, stop-cocks should be installed on the inlet and outlet pipes to allow the water
heater to be disconnected from the water supply during repair and/or replacement.
Each water heater is equipped with a safety relief and anti-drain valve, which should be
installed on the cold water inlet pipe (blue).
There may be a small amount of dripping from the safety relief valve which is normal du-
ring the heating stage, depending on the pressure of the water supply. In order to allow
this dripping to drain away, an open funnel should be positioned below the valve, connect-
ed to a drainage pipe flowing downwards and in a location where there is no condensation.
It is also recommended that the safety relief valve be manually operated periodically, in
order to clean out any lime and/or mineral deposits that may have built up and thereby
ensure the correct functioning of the water heater.
In cases where water pressure exceeds 5 bar, it is obligatory to install a pressure reducer,
either before the relief valve or where the water supply enters the building - as far as pos-
sible from the water heater, in either case. This should be fitted with a pressure gauge, in
order to regulate the reducer correctly.
them completely, an expansion tank can be installed between the water heater and the
relief valve.
The steps to follow to drain the water heater are as follows:
To reconnect the device, these steps should be followed in reverse order, ending with the
hot water tap being turned off.
Electrical connection
The appliance needs a circuit of at least 10 amps to operate.
nection for the device is obligatory as the manufacturer will not be held responsible for
any damage caused by a device that is not earthed or for anomalies in the electrical
supply. The use of heating, gas and water installation pipes to connect the appliance to
earth is prohibited.
The appliance is not protected against the effects of electrical storms.

It is prohibited to connect the appliance to the electrical supply until it has been filled
with water.
Electrical installation must always be carried out in compliance with the regulations in
force for each country.
The manipulation and/or substitution of any parts (including the electrical power sup-
ply cable) is strictly prohibited unless carried out by an Official Technical Support Technician.
