Installation Guidelines
Installation Diagram
Installation of Outdoor Unit
Install the outdoor unit in a manner to prevent mixing hot
discharged air with return air flow. Also, the unit should be a
suitable distance from obstructions (See Figure 1
)
for instal-
lation clearances. Double the dimensions shown if surround-
ings are more than 72" tall, or if there is an obstruction on
top. Select the coolest possible place where intake air tem-
perature is not greater than the outside air temperature (maxi-
mum 113°F).
Figure 1. Outdoor Unit Minimum Clearances
Installation of the Indoor Unit
Electrical wiring and installation must conform to all national
and local codes.
Voltage supply fluctuation must not exceed 10% of rated
voltage.
Ensure that the location is convenient for wiring, piping and
drainage.
The indoor unit must be installed near the center of the room
with no obstacles in path of the discharge or return air. See
Figure 2 for minimum clearances.
The suspending structure must be stronge enough to avoid
amplifying noise and vibration.
The height above the finished ceiling must be 13 3/4" mini-
mum (See Figure 4).
Avoid excessive heat. Do not install close to steam or hot
water pipes.
Figure 2. Indoor Unit Minimum Clearances
Locate and install four (4) 3/8" threaded hanging rods per
dimensions shown in Figure 3. Each rod must be able to sup-
port 50 lbs. minumum.
The dimensions of the cardboard template match Figure 3.
