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.
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
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.

(1) 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.
(4) Fault code function

[E2] Indicates a fault in the temperature sensor
[E4] Protection against overheating
ECO SELECTOR Technology
All WESEN water heaters allow precise and instant adjustment of water temperature,
thereby ensuring significant savings in terms of electrical consumption.
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.
Always:
- Disconnect the device from the electrical supply
- Close the cold water inlet stopcock
- Turn on a hot water tap
We recommend that you install a thermostatic valve set to a temperature of 39-41 ºC and
a flow rate of 6-8 litres per minute to obtain the best results from the appliance. This de-
vice will protect against burns as the water from the heater can reach 70 ºC or more. The
user should be aware of the risks involved in exposing parts of the body to excessively high
temperatures and take the necessary precautions to avoid them.
5. MAINTENANCE, CLEANING AND REPAIR
The water heater does not require any special maintenance and can be cleaned with a soft
damp cloth or sponge. Do not use abrasives or detergents.
Anode replacement
This appliance comes equipped with a magnesium anode for each electrical resistance. We
recommend that you check the condition of this every two years and replace it when ne-
cessary. Remember that this anode serves to protect the appliance against corrosion.
