notification is displayed.
▪ If the dirt becomes impossible to clean, change the air filter.

:
1
Remove the screws on the filter cover using screwdriver.
2
Slowly pull out the air filter (composed of 3 equal parts).

Clean the air filter. Use a vacuum cleaner or wash with water. If
the air filter is very dirty, use a soft brush and neutral detergent.

Dry the air filter in the shadow.
5
Re-attach the air filter. Partially re-insert the first part of the air
filter, align the middle part of the air filter with first part and push
the 2 clips in place to lock the filter parts together. Repeat the
procedure for the last part of the filter.

Maintenance before a long stop
period
E.g., at the end of the season.

power, even if it is not operating.
▪ Clean the air filter and the casing of the indoor unit (see

). Make
sure to install cleaned air filters back in the same position.
