C. INSTALLATION OF THE UNIT
C.4 WSE Sleeve Installation
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 C.4.1).
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 C.4.2, a properly installed unit
provides a
3
/8″ slope to the outside of the building.
NOTICE
Sleeve projections and leveling precautions must be
observed to prevent the entry of water into the room.

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 C.4.1). 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.
