Clearances
Provide enough space around the
unit to allow unrestricted access to
all service points. Refer to Figure 2
for unit dimensions and minimum
required service and free air
clearances. Observe the following
points to ensure proper unit
operation.
1.
Do not install the unit under a
low overhang. Condenser
discharge must not be restricted.
See Figure 2.
Note: Important! Do not
obstruct condenser
discharge air. This can
result in warm air
recirculation through the
coil.
2.
Do not locate the unit in a
position where runoff water can
fall into the fan discharge
openings.
3.
Condenser intake air is supplied
from three sides of the unit.
Adhere to the minimum
required clearances given in
Figure 2.
Unit Mounting
Rooftop Mounting
If the unit will be roof mounted,
determine for certain that the
structure is strong enough to
support the unit and any required
accessories. Unit weights are given
in Table 1. The unit should be
elevated on a level, field fabricated
four-inch steel or wood 4" x 4"
mounting frame. Complete the
frame and secure it into position
before lifting the unit to the roof. The
mounting frame must support a
minimum of three of the unit's four
sides and should span roof supports
to distribute the load on the roof.

Roof Mounted Unit
WARNING
Mounting Integrity!
Ensure that the roof structure
supports are strong enough to
support the weight of the unit and
any accessories. Failure to do so
could result in death or serious
injury or possible equipment or
property-only damage.
Ensure that the roof structure
supports are strong enough to
support the weight of the unit and
any accessories. Failure to do so
could result in death or serious
injury or possible equipment or
property-only damage.
The following warning complies with
State of California law, Proposition
65.
WARNING
Fiberglass Wool!
Product contains fiberglass wool.
Disturbing the insulation in this
product during installation,
maintenance or repair will expose
you to airborne particles of glass
wool fibers and ceramic fibers
known to the state of California to
cause cancer through inhalation.
Glass wool fibers may also cause
respiratory, skin or eye irritation.
Ground Level Mounting
For ground level installation, the unit
base should be adequately
supported and hold the unit near
level. The installation must meet the
guidelines set forth in local codes.
The support should extend two
inches beyond the unit base
channels at all points. The unit and
support must be isolated from any
adjacent structure to prevent
possible noise or vibration
problems. Any ground level location
must comply with required
clearances given in Figure 2.
Refrigerant Piping
Structural Preparation
Holes must be made in the structure
to run refrigerant lines. For the
majority of ground-level
installations, the holes can be made
in the header that rests on top of the
foundation. Alternatively, these
holes may also be made in the
foundation itself. On roof-mounted
units, refrigerant lines should enter
the building as close to the unit as
possible; preferably within three to
four inches of the refrigerant
connection on the unit, plus a 6-inch
(long radius) 90° ell entering the
building, Figure 1.
