Sleeve installation
STEP 1 After unpacking the WSC SLEEVE from the carton, remove the corrugated FRONT PANEL. Place 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 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 corrugated 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.
