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 possible
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 220-240 V single phase design. Before connecting it to the electri-
city supply, make sure that the mains supply and unit input features coincide.
Electrical installation must always be carried out in compliance with the applicable
Low-
Voltage Electronic Regulations
.
The following volumes and instructions must be taken into consideration when installing
water heaters in bathrooms or washrooms:
PROHIBITED AREA
This is the area delineated by the vertical planes that are tangent to the outer edges of bath-
tub, toilet pan or shower enclosure and by a horizontal plane situated 2.25 m above these
or the floor, should the units be embedded in it.
No switches, power sockets or lighting equipment should be installed within the PROHI-
BITED AREA. The heater must be installed outside this area.
PROTECTED AREA
This is the area delineated by the horizontal planes previously stated for the prohibited
area plus two vertical ones 1 m from these.
Switches must not be installed within the PROTECTED AREA. This does not apply, however,
to safety power sockets.
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.
– 7 –
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.
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 Tech-
nician.
4. OPERATION
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.

On-off switch
(2)
Power selection
By pressing the button (2), one or two power settings can be selected to obtain the
performance described in the technical characteristics section. The selected setting
will be indicated via the corresponding indicator light on the right-hand side.
(3)
Temperature selection
Water temperature can be adjusted by pressing the button (3). The default setting is
35 ºC. Holding down the button will increase the temperature in 5 ºC intervals until
75 ºC is reached. In the case of going past the desired temperature, continue to 75 ºC
and then press the button again to return to the default setting of 35 ºC.
The temperature will be set automatically when the button is released at the desired tem-
perature.
The thermostat will automatically disconnect the electrical connection when the pre-
determined temperature is reached. Once some water has been used and the tempe-
rature falls below the predetermined value, the thermostat will automatically reconnect
the electrical supply.
