3.2 INSTALLATION
• 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.

HOW TO INSTALL
Before installing the unit, identify the existing wall sleeve
from the list below.
NOTE: All wall sleeves used to mount the new Air
Conditioner must be in sound structural condition and have a
rear grille that securely attaches to sleeve, or rear flange that
serves as a stop for the Air Conditioner.
Remove old air conditioner from existing wall sleeve.
Clean the interior of an existing sleeve.
(Do not disturb seals.)
Wall sleeve must be securely fastened in wall before
installing the air conditioner. Use the nails or screws
through sleeve into wall, if needed. Repaint sleeve if
needed.
Prepare the wall sleeve for installation of the unit. If you
plan to use your existing wall sleeve, and it is not
FRIEDRICH, use procedure B or C below.
Install new unit into wall sleeve.
CAUTION: When installation is completed, replacement unit
MUST have a rearward slope as shown. To achieve 1/4"
slope, remove the backing from the 11-13/16" shim strips and
attach them as shown below in Fig. 19. Place the higher
portion of shim to the front of the rib on base of wall sleeve.

FIG. 19
Installing the FRIEDRICH USC sleeve ensures
optional performances of the unit.
If you decide to keep the existing wall sleeve, you have
to redirect the louvers at the back of the wall sleeve.
Refer to FIG. 23 on p15. The use of pliers is
recommended. If you DO NOT redirect, you run the risk
of poor performance or premature product failure. This
is not covered under the terms of the FRIEDRICH
warranty.
