SECTION XIV: INDOOR UNIT
INSTALLATION
1.
Shape the refrigerant line set so that it can be guided either out the
back of the indoor unit or through either side of the indoor unit
frame, then through the wall sleeve to the outside unit.
2.
Pass the drain hose and refrigerant pipes through the wall hole then
set the indoor unit on the mounting bracket hooks by using the
markings at the top of the indoor unit as a guide.
3.
Try moving the indoor unit to right and left to confirm that it is firmly
hooked on the installation plate.
4.
While pressing the indoor unit onto the wall, hook it at the lower part
on the installation plate.
5.
Carefully bend the bundle (line set, condensate line and cable) to
run along the outside wall toward the outdoor unit. Downward slope
of wall sleeve will ensure proper condensate drainage.
Pull the indoor unit toward you to confirm that it is firmly hooked
on the mounting bracket.
For detaching the indoor unit from the installation plate, pull the indoor
unit toward you while pushing the bottom up at the specified places.
6.
Use the provided foam insulation to wrap the factory installed con-
densate line.
7.
Connect indoor unit factory installed condensate line to field-pro-
vided condensate drain pipe.
8.
Use tape approved for waterproofing line connections to secure the
field-provided pipe to the factory-installed condensate line.
9.
Put water in the drain pan and make sure that the water is being
drained outside.
SECTION XV: OUTDOOR UNIT
INSTALLATION
Refer to page 4 instructions when considering unit positioning and page
4 for condensate drainage requirements (heat pump).
SLAB OR ROOF MOUNTING
• Install the unit a minimum of 4 inches (102 mm) above the roof or
ground surface to avoid ice build-up around the unit.
• Locate the unit above a load bearing wall or area of the roof that
can adequately support the unit.
• Consult local codes for rooftop applications.
