CARE AND MAINTENANCE
CAUTION!
Installing the Air Filter
Be sure the filter is always installed in the inlet air grille of the indoor unit.
Filters can be purchased through your local dealer.
Cleaning the Air Filter
If dirt is allowed to collect in the air filter, the airflow will be reduced, leading to reduced performance, and increased
operation noise. Be sure to clean the filters regularly.
How to Cleaning
Use a vacuum cleaner to remove dust and dirt from the air filter, or wash in a synthetic detergent. After washing, dry in a
shaded place, then reinstall.
G When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that the
unit be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized service
personnel.
G When cleaning the unit's body, do not use water hotter than 40°C, harsh abrasive cleansers, or volatile agents like ben-
zene or thinner.
G Do not expose the unit body to liquid insecticides or hairsprays.
G If the unit will not be operated for a period of one month or more, be sure to allow the inner parts of the unit to dry
thoroughly, in advance, by operating the unit in fan mode for half a day.
