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 wall-
sleeve 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.
