Installation Requirements; Sleeve Installation - Friedrich WS08 Installation & Operation Instructions

Installation requirements

STEP 1 The "WSC" SLEEVE should be positioned so that the DRAIN EXTENSION extends a
minimum of 9/16" beyond the OUTSIDE WALL (See Figure 8).
STEP 2 The "WSC" SLEEVE must extend a minimum of 7/8" beyond the INSIDE WALL.
STEP 3 The "WSC" SLEEVE must be installed level side to side.
STEP 4 The "WSC" 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 9, a properly installed unit provides a 1/2 bubble slope to the outside of the building.
CAUTION: SLEEVE projections and leveling precautions must be observed to prevent the
entry of water into the room.

Sleeve installation

STEP 1 After unpacking the "WSC" SLEEVE from the carton, remove the unpainted FRONT PANEL.
Locate the "WSC" 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 8). Shim at the top of the SLEEVE,
midway between the sides. Drive one #12A x 2" screw in the top of the sleeve, close to the shim.
Install screws from inside 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 1/2 bubble downward
tilt is maintained. Apply shims, if required, to maintain the proper slope.
STEP 3 Caulk the perimeter of the entire opening on the inside and the outside between the SLEEVE and
the WALL.
STEP 4 The unpainted front 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.
