Grille screw locations Completing Installation 1/8" Hole, Grille, and Flange #8 Screw Direct Unit Mounting The previous directions are the preferable way to mount the new rear grill. The unit's 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. 1. Attach the (2) seal pieces (1" x ⅜" x 14") as shown below. 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 fins of the grill 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 pre-drilled (some models), carefully drill four ⅛" holes through the grille and into the side flange of the unit approximately 1 ½" to 2" from the top and bottom as the images below. (Be careful not to drill into the copper heat exchanger coils.) 5. Install (4) #8 self- tapping screws to affix the grille to the unit. 6. Insert the unit into the sleeve. Completing Installation 1. Install the 1" x1 ½" x 84" long stuffer-seal between the wallsleeve and the unit. A flat-bladed screwdriver or putty knife is recommended. 2. Assemble the trim frame by inserting top and bottom pieces into side pieces and snapping into place. 3. Pull cord through trim frame then slide over unit until flush with wall.
