After removing air inlet filter, remove polypropylene net
type filter by detaching it from Unit’s body or from bottom
of inlet plenum.
Clean net type filter by using a vacuum cleaner adjusted
to min. suction capacity, in order to avoid to damage the
filtering net, as it is shown in Fig. 5. Dust must be sucked
up from the filter’s exterior side, that is normally
addressed towards the air inlet panel of Indoor Unit.
If air filter is very dirty, wash it under low pressure
running water (Fig. 6), or immerse it in just tepid water
and neutral soap. In both cases, carry out the cleaning
gently, in order to avoid to damage the filtering net.
Dry the net type filter in a shaded place and far from
heat sources.
Re-install the air filter properly by fixing devices.
Re-install Indoor Unit’s air inlet panel, by the reverse
procedure of that carried out for removal (Fig. 7).
