CARE AND MAINTENANCE

How to cleaning

•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 100 °F, harsh abrasive cleansers, or volatile agents like benzene or thinner.

•Do not expose the unit body to liquid insecticides or hairsprays.

•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.
