Clearances
The unit must be installed with sufficient clearance for air to 
enter the condenser coils, for air discharge and for servicing 
access. See Table Table 4 for clearances.
NOTE:  Additional clearance is required to remove the 
compressors out the back 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.
The unit 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.

Spreaders, longer than the largest dimension across the

Before lifting a unit, make sure that its weight is 
distributed equally on the cables so that it will lift evenly.
