C. INSTALLATION OF THE UNIT
C.5 Thru-the Wall Installation (Cont.)
WARNING
Falling Object Hazard
Not following Installation Instructions
for mounting your air conditioner can
result in property damage, injury, or
death.
The following instructions apply to wood, masonry, brick, concrete or cinder
block wall construction.
STEP 3. CABINET PREPARATION – Remove the sill plate from the cabinet
by removing two (2) nuts and screws (Figure C.5.4). Note that the
chassis retainer is secured by a right side nut and screw (Figure
C.5.4 Detail 1). Bend the tabs of the sill plate down into its channel
at both ends of the plate or cut them off (Figure C.5.4 Detail 2).
Rotate the sill plate 180° (end-to-end, Figure C.5.4 Detail 2) and
reinstall. Reverse the orientation of the nuts and screws, so that the
head of the screws are on the underside of cabinet facing up and
the nuts are on top (Figure C.5.4 Detail 3). Ensure that the chassis
retainer is reinstalled as shown in the detail.
NOTICE
The outside cabinet condenser air intake louvers
MUST NOT BE BLOCKED by extra thick walls.
STEP 4. WALL PREPARATION – The maximum wall thickness permissible without
special construction is determined by the model size to be installed. Observe
the maximum wall thickness shown in Figure C.5.6 Walls exceeding the
maximum thickness shown in the chart should be altered as shown in Figure
C.5.6
STEP 5. CHECKING WIRING AND PLUMBING – Check for wiring and
plumbing inside and outside of the wall to be sure none will be damaged
when the cabinet framework is being constructed.
STEP 6. OPENING CONSTRUCTION – Depending upon size of unit to be
installed, lay out the hole dimensions per Table 3. Cut and frame-
in the opening to finished dimensions. If the wall construction is a
typical frame, or 2" x 4" studding with brick or stone veneers, locate
the opening next to one of the studs. For masonry, concrete, or cinder
block walls, locate an opening for your convenience (see Figures C.5.7,
C.5.8, C.5.9).
