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.
1. Attach the 2 seal pieces (1 X3/8 X14 ) 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 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 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.)
5. Install 4 - #8 self tapping screws to affix the grille to the unit.
6. Insert the unit into the sleeve.
