Removing and cleaning the filter / fresh air and exhaust feature
To remove, wash and replace filter and return air grille
Open the return air (RA) grille by grasping it at the top
outside edges and pulling towards you (See Figure 4). The
RA grille will stay open until it is detached or closed (it is
easier to completely detatch the grille before closing it).
To remove the RA grille, grasp it at the bottom and pull
towards you.
The fi lter is held in place by two spring clips (See Figure 5).
Push down on the clips, grasp the fi lter and pull towards you
to remove it for cleaning. Clean with warm water and a mild
detergent, rinse, dry completely and replace. Use caution
when removing the fi lter. The internal metal components
are sharp.
If the RA grille has been removed, pick up the grille by
supporting it from both sides near the bottom (See Figure 5,
Note 1). Lift return air grille and insert the grille's tabs into
the bottom slots of the discharge air plenum (See Figure 5,
Note 2). Snap the grille into place by pushing the grille up
and onto the unit's latches at the bottom (See Figure 5, Notes
3 and 4).
Fresh air and exhaust control
Your air con di tion er has the ability to bring fresh air into the
room and ex haust stale air out of the room. The con trol le ver
is found on the upper part of the unit (See Fig ure 6).
TO BRING IN FRESH AIR - Move the lever to the FRESH
AIR position which allows outside air to enter the room.
This is useful in fall and spring as a means of bringing in
fresh outside air when using FAN ONLY. It can also be
used in the summer with the com pres sor in the Cool ing
Mode if you wish. Normally, for most effi cient operation,
cooling is ac com plished with this control in the middle or
closed position.
TO EXHAUST INDOOR AIR - Move the lever to the
EXHAUST position. This will allow stale air to be expelled
to the outside of the dwelling. This is es pe cial ly handy in
the winter when indoor air tends to get stale, or after a
social gathering involving smokers, or to re move odors
after cooking.
