Indoor coil
Outdoor coil
Unimpeded Outdoor Airflow
Do not block off the outside air flow to the unit. The
condenser air inlet and outlet must be free of
obstructions and of any external influence that would
cause the hot discharged condenser air to be re-
circulated back into the air intake. Outdoor air is drawn
into the condenser section via the air intake on the right
side of the rear grill. Hot condenser air is rejected at an
angle out of the left portion of the rear grill thereby
minimizing air re-circulation back into the intake.
Paper, leaves, dirt, or other material blocking airflow,
or fouling the condenser coil can impair efficiency and
cause serious damage to the compressor.
Oiling
The motors are permanently lubricated and do not
require re-oiling.
Unimpeded Indoor Airflow
Ensure that drapes, bed, bedspread, and furniture etc.
do not block the indoor air discharge and intake air
openings, causing a restricted air flow condition
through the indoor air handling section of the unit. Do
not place articles on discharge grille – especially
liquids.
Reducing Load
To reduce the cooling load, draw drapes or blinds in
the summer, to reflect direct rays from the sun.
To reduce the cooling and heating load, keep windows
and doors closed when operating the unit.
WALL SLEEVE CABINET INSTALLATION:
Install the wall sleeve cabinet in strict accordance with
the wall sleeve installation instructions, which are
supplied with the wall sleeve.
IMPORTANT:
The wall sleeve must be installed with a
zero to 1/8” per foot slope downward toward the outside
to ensure proper water drainage out the back edge of the
wall sleeve during overflow conditions, without
compromising the ability of the optional indoor drain
system to function properly (if used) . The specified slope
corresponds to a zero (level) to 1/8 bubble on a
carpenter’s level. The wall sleeve must also be level from
side-to-side.
ELECTRICAL WIRING AND RECEPTACLE
WIRE SIZING
A single outlet branch circuit from the main electrical
panel to the receptacle in the wall should be used.
Wire sizing shall be in accordance with the minimum
circuit ampacity as declared on the unit Rating Plate
for the specific chassis. Wire sizing must also take into
