Installation
WARNING
Heavy Objects!
Do not use cables (chains or slings) except as shown. Each of the cables
(chains or slings) used to lift the unit must be capable of supporting the
entire weight of the unit. Lifting cables (chains or slings) may not be of
the same length. Adjust as necessary for even unit lift. Other lifting
arrangements may cause equipment or property-only damage. Failure to
properly lift unit may result in death or serious injury. See details below.
Rigging
A Rigging illustration and Center-of-Gravity dimensional data table is shown
in Figure 5 and Table 1. Refer to the typical unit operating weights table
before proceeding.
1. Rig the condensing unit as shown in Figure 5. Attach adequate strength
lifting slings to all four lifting brackets on the lifting frame. Do not use
cables, chains, or slings except as shown.
2. Install spreader bars, as shown in Figure 5, to protect the unit and to facil-
itate a uniform lift. The minimum distance between the lifting hook and
the top of the unit should be 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 it into place.
Leveling the Unit
Use the unit base rail as a reference. Level the unit to within 1/4 inch over its
entire length. Use shims when required.
Shipping Fasteners
Compressor Shipping Hardware
Figure 6 illustrates the location of each tie down bolt and rubber isolator bolt
for the compressor assembly in each circuit. Refer to the illustration and the
following discussion to locate and remove the fasteners.
Two Manifolded Compressors
Each manifolded compressor assembly is rigidly bolted to a mounting rail
assembly. The rail assembly sets on four (4) rubber isolators. The assembly
is held in place by two shipping braces that secure each compressor
assembly rail to the unit's base rail. To remove the shipping hardware, follow
the procedures below:
1. Remove the four anchor bolts (2 front and 2 rear), used to secure the
shipping brace to the unit's base rail.
2. Remove the three self-tapping screws that secure each shipping brace to
the compressor mounting rails.
3. Remove and discard the two 30-1/2" long shipping braces for each
assembly.
4. Do not remove the shipping plate located on top of the compressors.
