The radiator is 1. Check and confirm that the heating element's output
not warming up is not too low for the size of radiator.
quickly 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.
Low water level 1. May happen once or twice after switching on - this is
(work in dry con- not a malfunction;
ditions) 2. If lasts longer - check the lever of heating agent level
Overheating 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.
