Installation and Operation Manual

To ensure proper unit operation, the air lter should be cleaned at least
monthly, and more frequently if conditions warrant. The unit must be turned
off before the lter is cleaned.

out of retainer. Remove lter from unit (Figure 3). Clean the lter monthly or
more frequently if needed. Refer to the Accessories section for lter options.
Coils & Chassis
NOTE: Do not use a caustic cleaning agent on coils or base pan. Use a
biodegradable cleaning agent and degreaser. The use of harsh
cleaning materials may lead to deterioration of the aluminum
ns or the coil end plates.
The indoor coil and outdoor coils and base pan should be inspected
periodically (annually or semi-annually) and cleaned of all debris (lint,
dirt, leaves, paper, etc.) as necessary. Under extreme conditions, more
frequent cleaning may be required. Clean the coils and base pan with a
soft brush and compressed air or vacuum. A pressure washer may also be
used; however, you must be careful not to bend the aluminum n pack. Use
a sweeping up and down motion in the direction of the vertical aluminum n
pack when pressure cleaning coils.
NOTE: It is extremely important to insure that none of the electrical
and/ or electronic parts of the unit get wet. Be sure to cover all
electrical components to protect them from water or spray.
Decorative Front
Use a damp (not wet) cloth when cleaning the control area to prevent water
from entering the unit, and possibly damaging the electronic control.
The decorative front and the cabinet can be cleaned with warm water and a
mild liquid detergent. Do NOT use solvents or hydrocarbon based cleaners
such as acetone, naphtha, gasoline, benzene, etc.
The indoor coil can be vacuumed with a dusting attachment if it appears
to be dirty. DO NOT BEND FINS. The outdoor coil can be gently sprayed
with a hose if you can get to it. If not, you might call your dealer for a more
thorough cleaning when needed.
The air lter should be inspected weekly and cleaned if needed by
vacuuming with a dust attachment or by cleaning in the sink using warm
water and a mild dishwashing detergent. Dry the lter thoroughly before
reinstalling. Use caution, the coil surface can be sharp.
Fan Motor & Compressor
The fan motor & compressor are permanently lubricated and require no
additional lubrication.
Wall Sleeve
Inspect the inside of the wall sleeve and drain system periodically (annually
or semi-annually) and clean as required. Under extreme conditions, more
frequent cleaning may be necessary. Clean both of these areas with an
antibacterial and antifungal cleaner. Rinse both items thoroughly with water
and ensure that the drain outlets are operating correctly. Check the sealant
around the sleeve and reseal areas as needed.
