Care and Maintenance / Fresh air and exhaust control

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 7). The RA grille will stay open until it is detached or closed (it is easier to completely detach the grille before closing it). To remove the RA grille, grasp it at the bottom and pull towards you.

The ¿lter is held in place by two spring clips (See Figure 7). Push down on the clips, grasp the ¿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 ¿lter. The coil surface can be sharp.

If the RA grille has been removed, pick up the grille by supporting it from both sides near the bottom (See Figure 8, Note 1). Lift return air grille and insert the grille's tabs into the bottom slots of the discharge air plenum (See Figure 8, Note 2). Snap the grille into place by pushing the grille up and onto the unit's latches at the bottom (See Figure 8, Notes 3 and 4).

Fresh air and exhaust control

Your air conditioner has the ability to bring fresh air into the room or exhaust stale air out of the room. The control lever is found on the upper part of the unit (See Figure 9).

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 ef¿cient 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 espe- cially handy in the spring or fall when indoor air tends to get stale, or after a social gathering involving smokers, or to remove odors after cooking.
