Air Filter
All indoor return air must be ltered. A washable lter is
furnished with the unit, located in the return air compartment.
If the optional front return opening is used and a duct is
installed, provisions must be made to accommodate lter
servicing. If a lter is installed at a separate central return
location, then the factory furnished lter must be removed
from the unit.
The lter should be cleaned at least three times during
each of the heating and cooling seasons, or more
frequently if unusual conditions are encountered. To clean
the washable lter, shake lter to remove excess dirt and/
or use a vacuum cleaner. Wash lter in soap or detergent
water and replace after lter is dry. It is not necessary to oil
the lter after washing.
The washable lter may be replaced with a disposable
lter. Table 4 lists lter sizes that t the unit.
If an installation is made in which it is more desirable to
mount the lter exterior to the unit, in the return duct work
or elsewhere, the washable lter can be used or replaced
with a disposable lter. If a disposable lter is used, use the
information provided in Table 5 when sizing the disposable
lter.
