WALLMASTER CHASSIS INSTALLATION INSTRUCTIONS FOR WS, WE AND WY MODELS
CAUTION
Excessive Weight Hazard
Use two or more people when installing your air conditioner.
Failure to so can resut in back or other injury.
CAUTION
Cut/Sever
Although great care has been taken to minimize sharp edges in the construction of your unit, use gloves or other hand protection when handling unit.
Failure to do so can result in minor to moderate personal injury.
STEP 1 Check the sleeve to be certain it has been correctly installed in the wall. Remove the front panel on the WSD SLEEVE. Remove the rear WEATHER PANEL. Reverse grille. Place lower edge into sleeve tab (Friedrich logo facing out). Aligns slots with screw holes. Secure grille with screws.
A.Check the anchor screws. There should be four
(4) in the WSD SLEEVE (two in each side).
B.Determine if the sleeve has a downward slope, to the outside, of ½ bubble on a level. See page 10 for further details.
C.Check to be sure the sleeve has been sealed around all edges with an industrial type caulking on both the outside and inside to prevent rain entry.
D.A sleeve sealing gasket has been provided in the chassis shipping carton. Remove it from the carton, peel the protective coating from the adhesive, and install it in the sleeve (adhesive down).
STEP 2 Check the electrical receptacle to see that it conforms to the requirements for the chassis model to be installed. See page 3, for the receptacle requirements.
STEP 3 The decorative front is packaged in a separate box inside the chassis shipping carton, between the chassis and the carton. Remove this box and set the box aside until later.
STEP 4 With the help of an assistant, remove the chassis from the shipping carton. Be careful not to allow anything to impact against the hairpins as this may result in damage to them. With the help of an assistant, lift the chassis by the basepan and slide it into the sleeve until it contacts the rear grille. With the chassis in proper position, the front edge of the basepan must extend out 4 ¾ inches from the front (side) edge of sleeve.
STEP 5 CHASSIS SEAL GASKET INSTALL ATION: After installing the shell, slide the chassis into the shell stopping approximately 3" from full insertion. Stuff the chassis seal gasket one inch deep between the chassis and the shell
(see Figure 9, Page 12). Make sure the gasket is installed beginning from the lower right side corner and extend- ing over the top and down to the lower left side corner. Then push the chassis all the way into the shell for the remaining distance so that the plastic front meets the front edge of the shell.
If foam chassis seal gasket is not installed, the operation of the unit will be negatively affected. Also, the operation noise and outside noise will be amplified.
STEP 6 Remove the intake grille from the decorative front frame by grasping it at the upper right and left side corners. Pull out until the grille is released from the upper retaining snaps. Tilt it down toward you, lift up and out of the bottom retaining snaps. Install the decorative front frame in place over the sleeve opening and attach it to the chassis with four sheet metal screws as shown in Figure 9, Page 12. Replace the intake grille by positioning the bottom of the grille into the bottom retaining snaps. Tilt the front up and away from you. Press in lightly on top, and the grille will position retaining snaps. itself into upper
NOTE: Attach the frame to the chassis by installing four (4)
