1. Check and confirm that the heating element's
output is not too low for the size of radiator.
2. (Dual Fuel only) — check the flow of the heated
agent is it flowing back into the central heating
system, if this is the case you will need to close one
of the valves (flow or return). In the case of a 'side
connection' you will need to close the upper valve. If
the problem continues contact Your dealer.
1. May happen once or twice after switching on - this
is not a malfunction;
2. If lasts longer - check the lever of heating agent
level
Check and reduce the water temperature in the
central heating system-must not exceed 82 deg
Check and confirm that the heating element's output
does not exceed the recommended output of your
radiator. Turn the heating element off with the ON/
OFF button and wait for 20 min. If the radiator is still
hot, disconnect it from its electrical supply - contact
the Distributor.
