Unit Installation - Outdoor Unit
Installation Clearances
Provide enough space around the unit
to allow unrestricted access to all
service points. Refer to unit space
clearance data for minimum required
service and free air clearances.
Observe the following points to insure
proper unit operation.
Refer to table 2 for reccomended
spacing.
a. Don't install the unit under low shield.
Keep discharge air freely.
Ground Level Mounting
The unit base should be adequately
supported and hold the unit near level.
Any ground level location must comply
with the required clearances. Place the
unit on a 102 mm cement support plate.
The support should extend 51mm
beyond the unit base channel at all
points. The unit and support should be
Isolated from any adjacent structure to
prevent possible noise or vibration
problem.
Important: Don't block discharge air.
This can result in warm air recirculation
through the coil.
b. Don't locate the unit in a position
where runoff water can drop into the fan
discharge openings.
c. Intake air can be supplied from 2
sides of unit.
Rooftop Mounting
If the unit is roof mounted, be sure the
structure is strong enough to support
the overall weight of the unit and all
accessories. Refer to Table 1 for unit
weight details.
Warning: Ensure the structure is strong
enough to support the gross weight of
unit and its accessories. Failure to do
will result in severe injury or death and
can seriously damage the unit and
building.
The unit should be elevated on a
horizontal, field-fabricated 102 mm steel
frame or 100 X 100 mm wooden
mounting frame. Complete the frame
and fix it firmly on the roof. The frame
must support a minimum of three of the
unit' s four sides and can span the roof
supports to distribute the load on the
roof.
