Installation
Lifting Recommendations
Before preparing the unit for lifting,
estimate the approximate center of
gravity for lifting safety. Because of
placement of internal components,
the unit weight may be unevenly
distributed. Approximate unit
weights are given in Table 1.

Warning:
On-sight lifting equipment
must be capable of lifting the unit
weight with an adequate safety factor.
The use of under-capacity lifting
devices may result in severe personal
injury or death and can seriously
damage the unit.
The crated unit can be moved using a
forklift of suitable capacity. For lifting
the unit, attach lifting straps or slings
securely to the lifting holes at each
corner. Use spreader bars to protect
the unit casing from damage. Test lift
the unit to determine proper balance
and stability.

Caution:
Use spreader bars to
prevent lifting straps from damaging
the unit. Install bars between lifting
straps. This will prevent the straps
from crushing the unit cabinet or
damaging the unit finish.
Clearances
Provide enough space around the
unit to allow unrestricted access
to all service points. Refer to unit
dimensional data for minimum
required service and free air
clearances. Observe the following
points to insure proper unit operation.
A. Do not install the unit under a low
overhang. Condenser discharge
clearance is not less than 2.5 mm.
Important:
Do not obstruct condenser
discharge air. This can result in warm
air recirculation through the coil.
B. Do not locate the unit in a position
where runoff water can fall into the
fan discharge openings.
C. Condenser intake air is supplied
from three sides of the unit. Adhere
to the minimum required clearances
given in dimensional data.
Unit 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 dimensional data.
