Installation Mechanical
Location Requirements
Isolation
To minimize unit sound and vibration transmission,
one of the following installation methods should be
used:
• Install the unit directly on an isolated (detached)
concrete pad or on isolated concrete footings
located at each unit load point. OR
• Install the optional neoprene or spring isolators at
each mounting location. See Unit Isolation section.
Foundation
Ground Level Installation
• If the unit is installed at ground level, elevate it
above the snow line.
• Provide concrete footings at each support location
or a slab foundation for support.
• See Weights table in Dimensions and Weights
chapter for the unit operating weights.
• See Unit Mounting section for mounting locations
and point loading weights when constructing the
footing foundation.
• Anchor the unit to the footings or slab using hold
down bolts or isolators.
• Isolators should be installed to minimize the
transmission of vibrations into the building. See
Unit Isolation section.
Rooftop Applications
For rooftop applications, ensure the roof is strong
enough to support the unit. See Weights table in
Dimensions and Weights chapter for the unit operating
weights.
Anchor the unit to the roof with hold-down bolts or
isolators. Follow the instructions in Unit Isolation
section for proper isolator placement and installation.
Check with a roofing contractor for proper
waterproofing procedures.
Leveling the Unit
Before tightening the mounting bolts, level the unit
carefully. Use the unit base rail as a reference. Level the
unit to within 1/4 inch over its entire length. Use shims
if non-adjustable isolators (neoprene) are used.
If adjustable isolators (spring) are used, ensure that the
proper isolator housing clearance is maintained while
leveling the unit. Isolators are identified by color and/or
an isolator part number. Shims under the isolators may
be required if the unit cannot be leveled using the
isolator leveling bolt.

See Weights table in Dimensions and Weights chapter
for unit weights. See
Table 4, p. 28 for center-of-gravity
information.
1. Rig condensing unit as shown in Figure 18, p. 27
and Figure 19, p. 27 . Attach adequate strength lifting
slings to all four lifting brackets. Do not use cables,
chains, or slings except as shown.
2. Install spreader bars as shown in Figure 18, p. 27 to
protect the unit and to facilitate a uniform lift.
Minimum distance between lifting hook and top of
unit is 7 feet.
3. Test-lift the unit to ensure it is properly rigged and
balanced. Make any necessary rigging adjustments.
4. Lift the unit and position into place.
