Wallmaster Chassis Installation Instructions "Ws", "We" And "Wy" Models - Friedrich WS08 Installation & Operation Instructions

WallMaster chassis installation instructions
"WS", "WE" and "WY" models
These instructions are provided for installation of WallMaster air conditioner chassis models into thru-the-wall sleeves. This
chassis has been UL approved with the sleeve listed on the serial nameplate of this chassis. Important warranty information is
provided on pages 14 and 15. Keep these instructions in a convenient location for any warranty service that may be required.
STEP 1. Check the sleeve to be certain it has been correctly installed in the wall. Remove the unpainted front
panel on the "WSC" sleeve. Remove the rear WEATHER PANEL. Leave the rear grille in place.
Discard the other items taken out.
A. Check the anchor screws. There should be fi ve (5) in the "WSC" SLEEVE (two in each side and one in
the top center).
B. Determine if the sleeve has a downward slope, to the outside, of 1/2 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 caulk ing on both the
outside and in side to prevent rain entry.
STEP 2. Check the electrical receptacle to see that it conforms to the requirements for the chassis model to be in stalled. See
pages 2 and 5, for the re cep ta cle requirements.
STEP 3. The decorative front is packaged in a separate box inside the chassis shipping carton, be tween 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. Remove the cardboard which is placed
against the hair pins and is taped to the condenser shroud (see Figure 10). Be careful not to allow anything to im-
pact against the hairpins as this may result in dam age to them. IMPORTANT: Before installing the unit in the wall
sleeve, remove the two yellow shipping blocks. One shipping block is fi xed directly below the control panel on the
front, left side of the unit. A second shipping block is located directly below the left side of the control panel. (see
Figure 11). 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 4-3/4 inches from
the front (side) edge of sleeve.
