• The wall opening must be the correct size. See
Figure 1 for wall sleeve dimensions and Figure 2
for minimum wall opening size.
• The wall sleeve will need to be installed with
minimum clearances to the floor and adjacent
walls. Minimum projections of the sleeve into and
out of the room will also have to be met. See
Figures 3 and 4 as well as Table 1 for details.
• If installed in a concrete or masonry wall, a lintel
must be provided in the wall opening for support.
Do not use the wall sleeve as a lintel. See
Figure 5 for a typical lintel construction.
• When installed in the opening, the wall sleeve
must be horizontally level from side to side and
pitched (one quarter bubble in the sight glass) to
the outside. DO NOT SLOPE THE WALL SLEEVE
TOWARD THE ROOM. (Figure 5)
• The installer must determine and supply the
mounting bolts and/or screws to attach the wall
sleeve to the sides of the wall opening. Make sure
the wall opening is adequate for strong support.
• The installer must provide adequate sealing and
insulation around the sleeve after it is installed.
See Figure 6 for one of many types of construc-
tions.
• If used, a 208/230-volt wall receptacle must be
located within 58 inches of the lower right sleeve
corner. Extension cords must not be used with the
unit. See the note on Figure 1.
• For installations in walls deeper than 13-7/8
inches, special care is necessary to prevent
problems with rain water, condensate drainage
and intake/discharge air. Under these circum-
stances, careful job site analysis and precautions
are required. You must consult with your Sales
Representative and receive approval before
attempting such installations.
OUTDOOR ENCLOSURE PANEL REMOVAL
The sleeve stiffener must be taken out before the
enclosure panel can be removed from the sleeve.
1. Remove the zig-zag folded cardboard sleeve stiffener
(Figure 7).
2. Remove the rear closure panel by folding the four
flaps as indicated in Figure 8.
3. Grasping the top and bottom flanges of the rear clo-
sure panel as shown in Figure 9, the entire panel is
pulled out diagonally from one side.
Install the wall sleeve condenser air grille by using the
screws and holes provided. (See the Installation Instruc-
tions provided for the grille kits.)
