Condensing Unit Rigging and Mounting
Rigging holes are provided on all units. Caution should be exercised when
moving these units. To prevent damage to the unit housing during rigging,
cables or chains used must be held apart by spacer bars. The mounting
platform or base should be level and located so as to permit free access of
supply air.
Ground Mounting
Concrete slab raised six inches above ground level provides a suitable base.
Raising the base above ground level provides some protection from ground
water and wind blown matter. Before tightening mounting bolts, recheck
level of unit. The unit should in all cases be located with a clear space in all
directions that is at a minimum, equal to the height of the unit above the
mounting surface. A condensing unit mounted in a corner formed by two
walls, may result in discharge air recirculation with resulting loss of capacity.
Roof Mounting
Due to the weight of the units, a structural analysis by a qualied engineer
may be required before mounting. Roof mounted units should be installed
level on steel channels or an I-beam frame capable of supporting the weight
of the unit. Vibration absorbing pads or springs should be installed between
the condensing unit legs or frame and the roof mounting assembly.
Access
Provide adequate space at the compressor end of the unit for servicing.
Provide adequate space on the connection side to permit service of components.
Spring Mounted Compressor
Compressors are secured rigidly to make sure there is no transit damage.
Before operating the unit, it is necessary to follow these steps:
Remove the upper nuts and washers.
Discard the shipping spacers.
Install the neoprene spacers. (Spacers located in the electrical
panel or tied to compressor.)
Replace the upper mounting nuts and washers.
Allow 1/16 inch space between the mounting nut/washer and
rubber spacer. Mounting spring must not be fully compressed
when mounting nut is properly installed. See Figures 3 and 5.
Rigid Mounted Compressor
Some products use rigid mounted compressors. Check the compressor
mounting bolts to insure they have not vibrated loose during shipment. See
Figure 4.
