— 1 4 — 3.2 INST ALLA TION • Pick a location which will allow the conditioned air to blow into the area you want. Good installation with special attention to the proper position of the unit will lessen the chance that service will be needed. ITEMS IN INSTALLATION HARDWARE You may not need all parts in the kit.
P R OCEDURE If you are using the new sleeve (optionally A s u pplie d w it h y o u r unit),sk i p t o ste p 3 . Otherwise, install the plastic grille from the kit. Cut the plastic grille to 25-1/2" wide and 15-1/4" high. Place the plastic grille to the inside of the wall sleeve at the rear flange.
— 16 — PR OCEDURE B Redirect the louvers at the back of the wall sleeve to 60 ° angle as shown in the FIG 8 . The use of pliers is recommended. If the wall sleeve already has a rear grille, skip to step 4. If the wall sleeve does not have a rear grille or louvered panel, install the plastic grille from the kit.
— 1 7 — PR OCEDURE B CONTINUED Remove the backing from the support blocks and attach them to the inside of the wall sleeve as shown FIG 29 . Slide the baffle into slots of the support blocks. Install the new unit into the wall sleeve. Assemble trim as described in Step 6, Procedure A.
