Clearances
The unit must be installed with sufficient clearance for air to
enter the condenser coil, for air discharge and for servicing
access. See Table 4 for clearances.
NOTE:
Additional clearance is required to remove the
compressors out the back of the unit, unless a means is
available to lift the compressor out through the top of
the unit.
Rigging
Exercise care when moving the unit. Do not remove any
packaging until the unit is near the place of installation. Rig the
unit by attaching chain or cable slings to the lifting holes
provided in the base rails. Spreader bars, whose length
exceeds the largest dimension across the unit,
MUST
be used
across the top of the unit.
Units may be moved or lifted with a forklift. Slotted openings in
the base rails are provided for this purpose.
LENGTH OF FORKS MUST BE A MINIMUM OF 60 INCHES
.

Do not permit overhanging structures or shrubs to
obstruct condenser air discharge.
Spreaders, longer than the largest dimension across the
unit must be used across the top of the unit.
Before lifting a unit, make sure that its weight is
distributed equally on the cables so that it will lift evenly.
