Installation or removal
Detailed information about the different ways of installing or re-
moving the radiator heating element are available from the manu-
facturer or importer (see footnotes at the end of the manual). Be-
low we list some basic requirements and principles which must be
followed to ensure long term reliable operation.
To ensure the long term reliability of the device, the correct power
output must be selected. The power output of heating element
must be lower than the power of the radiator for the parameters of
75/65/20° C. Operating the heating element with a power output
that is too high can cause rapid wear of the temperature regula-
tor and, consequently, the failure of the heating element, which is
not covered by the warranty. We recommend selecting a heating
element wattage of between 70% and 100% of the radiator power
output for 75/65/20° C parameter.
Before installation or first use:
1. Read the chapter Safety requirements — installation.
2. Fit the heating element using the correct spanner (size 22).
3. The heating element must be installed at the bottom of the
radiator, perpendicular to the radiator pipes, preserving space
for proper circulation of the heating medium.
4. Use a suitable heating medium for filling the electric radiator
(water, special products based on water and glycol for use in
central heating, oil complying with the requirements of the
manufacturer of radiator and heating element).
5. Do not switch the heating element on if it is not fully im-
mersed in radiator heating medium .
6. Make sure an adequate air cushion is present to protect
against excessive pressure build up in the heater (always leave
one of the radiator valves open).
7. When filling the radiator with hot liquid make sure its tem-
perature does not exceed 65° C.
8. Follow the subsequent guidelines when connecting the electri-
cal installation:
a. Brown wire — live connection to the circuit (L).
b. Blue wire — connect to neutral (N)
c. Yellow & green wire — earth connection (PE).
9. Before filling the radiator with heating medium, make sure
that heating element is fitted properly to guarantee that it is
water tight.
