Brand Wall Sleeve Dimensions (inches)

fig-1

NOTE: All wall sleeves used to mount the new Air Conditioner must be in sound structural condition and have a rear grille that securely attaches to the sleeve or a rear flange that serves as a stop for the Air Conditioner.
CAUTION: When the installation is complete, the replacement unit MUST have a rearward slope as shown.

Remove the old Air Conditioner from the wall sleeve and prepare the wall sleeve as follows:
Clean interior (do not disturb seals).
Wall sleeves must be securely fastened to the wall before installing the Air Conditioner.
Drive more nails or screws through a sleeve, into a wall, if needed.
Repair paint if needed.
If not existing, drill a 1/8 clearance hole for the grounding screw through the left side of the wall sleeve, in a clear area about 3 inches maximum back from the front edge of the sleeve, using the grounding screw and toothed washer. Pull the loose end of the ground wire out front of the sleeve, and temporarily bend it down and around the lower edge of sleeve. This ground wire will later be attached to the frame of the air conditioner once it is installed.

Prepare the wall sleeve for installation of the new unit per the following Brand instructions.

Identify your wall sleeve type and follow the instructions for that type in the following pages.

Direct Unit Mounting

The previous directions are the preferable way to mount the new rear grill. The units performance is slightly better and the possibility of draughts is reduced. As a last resort, direct mounting of the grille to the unit can be considered.
Note: The grille must be installed prior to inserting the unit into the sleeve.

Attach the 2 seal pieces (1 X3/8 X14 ) as shown in Fig. 1.
Position the grille over the rear of the unit making sure that:
- The double set of screw holes are at the bottom.
- The fins of the grill are pointed away from the unit.
Align the top of the grille with the top of the unit. The overhang on each side is equal.
If the unit has not been pre-drilled (some models), carefully drill 4-1/8 holes through the grille and into the side flange of the unit approximately 1 to 2 from the top and bottom as in Fig. 2, 3 .
(Be careful not to drill into the copper heat exchanger coils.)
Install 4 – #8 self tapping screws to affix the grille to the unit.
Insert the unit into the sleeve.
