Installation & Operation Manual

40 41
The following instructions apply to wood, masonry, brick, concrete or cinder
block wall construction.
STEP 1. Follow Steps 1, 2, 3, and 4 of the “STANDARD WINDOW
INSTALLATION” instructions beginning on Page 29.
STEP 2. CABINET PREPARATION – Remove the sill plate from the
cabinet by removing two (2) nuts and screws (Figure 78).
Note that the chassis retainer is secured by a right side
nut and screw (Detail A, Figure 78). Bend the tabs of the
sill plate down into its channel at both ends of the plate or
cut them off (Detail B, Figure 78). Rotate the sill plate 180°
(end-to-end, Detail B, Figure 78) 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 (Detail C, Figure 78). Ensure that the chassis
retainer is reinstalled as shown in the detail.
STEP 3. 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 79.
Walls exceeding the maximum thickness shown in the chart should
be altered as shown in Figure 79.
STEP 4. 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 5. 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 nished 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 80, 81, and 82).
NOTICE
The outside cabinet condenser air intake louvers
MUST NOT BE BLOCKED by extra thick walls.
