3. INSTALLATION OF THE ELECTRIC WATER HEATER

The following items are supplied with the electric water heater:
- 1 safety relief valve
- 2 hook screws (for 30 and 50 l) / 4 hook screws (for 80 and 100 l)
This model is designed to be attached to a wall. In order to attach the water heater to the
wall, first check the wall carefully to ensure that it is strong enough and use the appropriate
screws and rawl plugs. Two hook screws and rawl plugs are supplied with the appliance and
it is recommended that you use them.
The electric water heater should be positioned as close as possible to the place where the
hot water will be used, in order to reduce the distance the hot water has to travel through
the pipes and thereby maintain its temperature.
The device should be positioned with at least 60 cm of clear space below the pipe outlets,
in order to facilitate any maintenance and/or repair which may need to be carried out.
Location recommendations
This device is designed to be installed inside buildings which comply with current regula-
tions. The following warnings must be taken into consideration:
• Do not connect the device directly to electrical circuits that are unprotected from
power surges.
• Do not install the device in particularly aggressive environments with acid vapors and/or
dust, or in gas-saturated environments.
• Do not install the device in a location where the temperature is likely to go so low that
ice could form.
This water heater is designed to be installed vertically, with the pipes positioned toward the
ground.
It may be necessary to install a discharge pipe in order to remove any drops of water which
could be released from the safety relief valve. Under no circumstances will NIELSEN
CLIMA ESPAÑA, S.L. be held responsible for any damage to property caused by these pos-
sible leaks.
Hydraulic connection
Connect the water heater water inlet and outlet to pressure- and temperature-resistant
pipes or connectors. Water temperature can exceed 80 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, connected 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 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 220/230 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.
