7
• 19¾" high by 25 / " wide (18000 Btu model)

Lower left inside corner of opening must be within 6' of
appropriate electrical outlet.
For proper condensate drainage when installed, back of
case should be 3 / " lower than front of case. Inside edge

of case must extend ¾" beyond inside wall to properly
seat air conditioner front cover. After installation, caulk
completely around outside of unit to ensure proper seal.
Depending upon wall construction and opening location,
a lintel (not provided) may be required.
!
CAUTION
To reinstall chassis and reattach front cover, outer
case must be square and level from side to side.
Use wood shims between sides of case and
finished opening—especially where case is secured
to opening—to prevent warping or distorting case.
Check installation with carpenters' square.
To improve appearance, framing inside opening with
decorative molding (not provided) may be desired. If
molding is used, mount case in opening so inside edge
of case extends ¾" beyond molding.
When installing unit through thick walls (12000 Btu unit
in walls thicker than 9"; 18000 Btu unit in walls thicker
than 14½"), be sure air flows freely through side louvers
on outer case. See Installation in Walls Exceeding Outer
Case Dimensions.
