● Dust can be cleaned from the air fi lter either with a vacuum cleaner,
or by washing the fi lter in a solution of mild detergent and warm water.
If you wash the fi lter, be sure to allow it to dry thoroughly in a shady
place before reinstalling.
● If dirt is allowed to accumulate on the air fi lter, airfl ow will be reduced,
lowering operating effi ciency and increasing 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 shutting down the unit for one month or more, fi rst allow the
fan mode to operate continuously for about one-half day to allow
internal parts to dry thoroughly.
