●Dust can be cleaned from the air filter either with a vacuum cleaner, or by washing the filter in a solution of mild de- tergent and warm water. If you wash the filter, be sure to allow it to dry thoroughly in a shady place before rein- stalling.

●If dirt is allowed to accumulate on the air filter, air flow will be reduced, lowering operating efficiency and increas- ing noise.

●During periods of normal use, the Air Filters should be cleaned every two weeks.

●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 104 °F, harsh abrasive cleansers, or volatile agents like benzene or thinner.

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

●When shutting down the unit for one month or more, first allow the fan mode to operate continuously for about one-half day to allow internal parts to dry thoroughly.
