CAUTION!
Before cleaning the unit, be sure to stop the unit and power supply. (Turn off the electrical breaker)
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.
●
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.
●
When cleaning the unit’s body, do not use water hotter than 40 °C, harsh abrasive cleansers, or volatile agents like benzene
or thinner.
●
Do not expose the unit body to liquid insecticides or hairspray.
●
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.
When the error indication “E:EE” is displayed, inspection of the air conditioning system is necessary. Please consult author-
ized service personnel.
