CLEANING AND CARE

 CAUTION

3. Re-attach  the  air  filters  to  the  intake 

grille.

The air filters fit onto the inside of the intake grille. 

  Dust  can  be  cleaned  from  the  air  filter  either  with  a 

vacuum cleaner, or by washing the filter in a solution 

of mild detergent and warm water. If you wash the filter, 

be sure to allow it to dry thoroughly in a shady place 

before reinstalling.

  If dirt is allowed to accumulate on the air filter, air flow 

will  be  reduced,  lowering  operating  efficiency  and 

increasing noise.

Cleaning the Air Filter

1. Pull  the  air  filters  upward  to  remove 

them.

  Remove the air filters by raising its handle while pulling it 

out towards you.

2. Clean the air filters.

  Remove the dust from the air filters by vacuuming or wash-

ing them. After washing, allow the air filters to dry thoroughly 

in an area protected from sunlight.

  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.
