or connectors. Water temperature can exceed 75 ºC; therefore materials which are not able
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.
In order to reduce water leakages from the relief valve as far as possible, and/or eliminate
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:
1- Disconnect the water heater from the electrical supply
2- Close the stop-cock to shut off the water supply
3- Open the safety relief valve drainage lever
4- Turn on any hot water tap
To reconnect the device, these steps should be followed in reverse order, ending with the
hot water tap being turned off.
Electrical connection
The water heater is of 220 V~ single phase design. Before connecting it to the electricity
supply, make sure that the mains supply and unit input features coincide.
The appliance needs a circuit of at least 10 amps to operate.
The power cord and plug must always be kept dry in order to avoid electrical leakage.
All electrical installations must incorporate an "EARTH" connection. The earthing con-
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 use of adaptors and multiple power sockets 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.
NOTE: The manipulation and/or substitution of any parts (including the electrical power
supply cable) is strictly prohibited unless carried out by an Official Technical Support
Technician.

4. OPERATION

Safety precautions
Before connecting the water heater to the electricity supply, it must be filled with water.
To do so, once the water heater has been installed, open the stopcock and turn on the hot
water taps. When water starts to come out, close the outlet taps, making sure that there
are no leakages. Do not connect the water heater to the electricity supply until you are
sure that the tank is completely full of water.
If the water heater is not going to be used for a long period of time and/or if there is a risk
of freezing, the device must be emptied via the safety relief valve.
