The return air filter needs periodic maintenance.
Check and clean the filters each week when in use to pre-
X
vent the filters from being blocked by dirt.
The filters should be washed frequently to ensure effective
X
cooling and heating.
Pull out the filter from the air distributor before washing
X
them in warm water with a touch of detergent.
NOTE
■ Replacement filters can be ordered separately.
■ Never operate the air conditioner without a fil-
ter. This can cause fouling of the heat exchang-
er and lead to a loss of power.
Change the remote control batteries (2xAAA type) when the
display of the remote control becomes unreadable and/or
blurry.
Do not dispose of any batteries with general
household waste. Return defective or used bat-
teries to your retailer or dispose of them at a col-
lection point.
NOTE
Remove the batteries from the remote control if
the remote control is not used for a long time to
prevent damage to the remote control from
leaking batteries.
