TION INSTRUCTIONS
Installation Instructions
Direct Unit Mounting:
The previous directions are the preferable way to mount the new rear grille. The units performance is slightly
better and the possibility of drafts 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 3/8” x 14”) as shown in the illustration.
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 grille are pointed away from the unit.
3. Align the top of the grille with the top of the unit. The overhang on each side should be equal.
4. 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 1-1/2” to 2” from the top and bottom as shown.
5. Install 4 #8 self-tapping screws to affix the grille to the unit.
6. Insert the unit into the sleeve.
