Direct Unit Mounting

In cases where the dual intake grille cannot be mounted directly to the sleeve it is desirable to attach the

grille to the back of the through-the-wall air conditioner to the holes predrilled in the unit.

1. Attach the 2 seals (1” x 3/8” x 14”) as shown in Fig. 1.

2. Position the grille over the rear of the unit making sure that:

a. The double set of screw holes are at the bottom

b. The intake fins on either side are pointed away from the unit.

3. Align the top of the grille with the top of the unit. The overhang on each side is equal.

4. If the unit has not been predrilled (some models), carefully drill 4 – 1/8” holes through the grille and

into the side flange of the unit approximately 1 ½” to 2 “ from the top and bottom as in Fig. 2 & Fig. 3.

(Be careful not to drill into the copper heat exchanger coil)

5. Install 4 - #8 self-tapping screws to affix the grille to the unit.

6. Insert the unit into the sleeve.
