CAUTION
Excessive Weight Hazard
Use two or more people when installing your
air conditioner.
Failure to do so can result in back or other
injury.
STEP 1. Check the sleeve to be certain it has been correctly installed
in the wall. Remove the front panel on the WSE SLEEVE.
Remove the rear WEATHER PANEL. Reverse grille. Place
lower edge into sleeve tab (Friedrich logo facing out). Align
slots with the screw holes. Secure grille with screws.
A. Check the anchor screw. There should be four (4) in the WSE
SLEEVE (two in each side).
B. Determine if the sleeve has a downward slope of
3
/8″ to the
outside. See Page 26 for further details.
C. Check to be sure the sleeve has been sealed around all
edges with an industrial type caulking on both the outside
and inside to prevent rain entry.
STEP 3. Check the electrical receptacle to see that it conforms to the
requirements for the chassis model to be installed. See Page 5
for the receptacle requirements.
STEP 3. Remove the chassis from the shipping carton. Lift the chassis
by the basepan and slide it into the front of the sleeve. (Obtain
assistance as needed.) Push the chassis all the way into the
sleeve, using the plastic front handles, so that the front panel
meets the front edge of the shell.
NOTE: Chassis comes with pre-installed seal gasket.

CAUTION
Cut/Sever
Although great care has been
taken to minimize sharp edges
in the construction of your unit,
use gloves or other hand
protection when handling unit
Failure to do so can result in minor
to moderate personal injury.

Installation Requirements
STEP 1. The WSE sleeve should be positioned so that the drain
extension extends a minimum of
9
/16″ beyond the outside wall
(see Figure 48).
STEP 2. The WSE sleeve must extend a minimum of
7
/8″ beyond the
inside wall.
STEP 3. The WSE sleeve must be installed level side to side.
STEP 4. The WSE sleeve must also be installed with a downward tilt
toward the outside of the building. If a level is placed so that
it rests on the front and back unit rest as shown in Figure 49, a
properly installed unit provides a
3
/8″ slope to the outside of the
building.
Sleeve Requirements
STEP 1. After unpacking the WSE sleeve from the carton, remove the
indoor weather panel. Place the WSE sleeve in the wall opening
following the instructions given in the Installation Requirements.
Attach the sleeve to the inside wall by driving two #12A x 2″
screws in each side of the sleeve (see Figure 50). Shim at the
top of the sleeve, midway between the sides. Drive one #12A
x 2″ screw in the top of the sleeve. If the wall opening is not
framed with wood, use expansion anchor bolts or molly (toggle)
bolts (not provided).
STEP 2. Once the sleeve has been installed, check the level again to be
sure the
3
/8″ downward slope is maintained.
NOTE: If necessary, apply shims below the chassis and inside
the sleeve front unit rest, to ensure a
3
/8″ downward slope front
to back.
STEP 3. Caulk the perimeter of the entire opening on the inside and the
outside between the sleeve and the wall.
STEP 4. The indoor weather panel removed in Step 1 above must be
remounted back in place if masonry work is to be done and/ or if
the “WallMaster”chassis is to be installed at a later date.
How to cover inner weather panel holes
Two beige plugs are included in the plastic bag taped to the WallMaster
chassis. These plugs may be used to cover the two holes left after removing
the indoor weather panel.
