2. TECHNICAL CHARACTERISTICS

The double tank used in this electric water heater has passed quality controls via the co-
rresponding pressure tests. The material used for these tanks is anti-corrosive stainless
steel.
If excessive pressure is detected in the tanks, the safety relief valve, installed on the cold
water inlet, will be activated to ensure the safety of the appliance.
This model has the following power settings:
SILVER FLAT 30, 50, 80 and 100 litres:
- Single power function: 1300 W
- Double power function: 2000 W
The user can choose the most appropriate setting for their needs.

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
