and reduces efficiency. The air filter should be cleaned once a
month. More frequent cleaning may be necessary depending on
outdoor and indoor air quality.
Air Filter Removal
The air filter is located behind the air intake front grill.
To remove the air filter, open the air inlet grille and take out the air
filter.
To reinstall the air filter, reverse the above procedure.
