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 1). 

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 2, 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.

After unpacking the “WSC” SLEEVE from the carton, remove the corrugated FRONT PANEL.  
For immediate installation of sleeve and chassis (skip if installing chassis into sleeve at a later date):

Remove the rear WEATHER PANEL. Reverse grille and place lower edge into sleeve tab (Friedrich logo facing

out). Align slots with screw holes. Secure grille with screws. 

Place “WSC” SLEEVE in the wall opening following the instructions given in the INSTALLATION REQUIRE-

MENTS section. Attach the SLEEVE to the INSIDE WALL by driving two #12A x 2” screws in each side of the 

SLEEVE (see Figure 1.). 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). 

Sharp edges and corners. Be careful with 

the sharp edges and corner. Wear protective 

clothing and gloves, etc.

Failure to do so could result in serious injury.

Once the SLEEVE has been installed, check the LEVEL again to be sure the 1/2 bubble downward tilt is main-

tained. Apply shims, if required, to maintain the proper slope. 

Caulk the perimeter of the entire opening on the inside and the outside between the SLEEVE and the WALL. 

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 “WSC” CHASSIS is to be installed at a later date. 

Be careful with the sharp edges and corners. 

Wear protective clothing and gloves, etc.

Failure to do so could result in serious injury.
