Cleaning.
WARNING – ALWAYS DISCONNECT FROM THE POWER
SUPPLY BEFORE CLEANING THE HEATER.
We recommend cleaning the following components once
every 2 weeks, particularly in hard water areas:-
Water Tank, Sump and Seal, Sump lid, Tank cap and seal,
Air filter.
For general cleaning use a soft clean duster – never use
abrasive cleaners. To remove any accumulation of dust or
fluff the soft brush attachment of a vacuum cleaner should
occasionally be used to clean the outlet grille of the fan
heater.

and empty water.

of the cap paying particular attention to the rubber ring in
the outer groove and the centre rubber seal.

refit the cap and shake well, rinse out until all traces of
washing up liquid are gone.
