Installation requirements
STEP 1 The WSD SLEEVE should be positioned so that the DRAIN EXTENSION extends a minimum of 916" beyond the OUTSIDE WALL (See Figure 7).
STEP 2 The WSD SLEEVE must extend a minimum of ⅞" beyond the INSIDE WALL.
STEP 3 The WSD SLEEVE must be installed level side to side.
STEP 4 The WSD 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 8, a properly installed unit provides a ½ bubble slope to the outside of the building.

Sleeve installation
STEP 1 After unpacking the WSD SLEEVE from the carton, remove the FRONT PANEL. Place the WSD SLEEVE in the wall opening following the instructions given in the INSTALLA- TION REQUIREMENTS. Attach the SLEEVE to the INSIDE WALL by driving two #12A x 2" screws in each side of the SLEEVE (see Figure 7). 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).
Please note that there will be an excess of two #12Ax2" screws that will not be used.
STEP 2 Once the SLEEVE has been installed, check the LEVEL again to be sure the ½ 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 front panel removed in Step 1 above must be remoun- ted back in place if masonry work is to be done and/or if the "WallMaster" CHASSIS is to be installed at a later date.
