Removing and cleaning the filter / freshair 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 3). The
RA grille will stay open until it is detached or closed. If
you need to remove the RA grille, grasp it at the bottom
and pull towards you.
The filter is held in place by two spring clips (see figure 4).
Push down on the clips, grasp the filter 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 filter. The internal metal
components are sharp.
If the RA grille has not been completely detached, close it
by grasping it at the top outside edges and pushing it towards
the unit until it snaps shut.
If the RA grille has been removed, reposition it bottom first,
while lining up the control panel opening with the control
panel itself (see figure 3). Once it is lined up, push in at the
bottom of the RA grille until you hear it snap into place.
Now close it by grasping the top outside edges and pushing
it towards the unit until it snaps shut.

Fresh air and exhaustcontrol
Your air conditioner has the ability to bring fresh air into the
room and exhaust stale air out of the room. The control lever
is found on the upper part of the unit (see Figure 5).
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 compressor in the Cooling
Mode if you wish. Normally, for most efficient operation,
cooling is accomplished 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 especially handy in
the winter when indoor air tends to get stale, or after a
social gathering involving smokers, or to remove odors
after cooking.
