RIGGING AND HANDLING
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 with hooks to
the round lifting holes provided in the base rails.
Units may also be moved or lifted with a forklift from the front,
rear or the compressor end only through the slotted openings
provided in the base rails.
Remove the nesting brackets from the four corners on top of
the unit. All screws that are removed to take these brackets
off must be replaced on the unit.
CLEARANCES
All units require certain minimum clearances for proper oper-
ation and service. Refer to Table 5 for these clearances.
Additional height may be required for snow clearance if win-
ter operation is expected.
POWER AND CONTROL WIRING
Install electrical wiring in accordance with the latest National
Electrical Code (NFPA Standard No. 70) and/or local regula-
tions. The unit should be grounded in accordance with these
codes.
POWER WIRING
Check the voltage of the power supply against the data on
the unit nameplate. Check the size of the power wire, the dis-
connect switch and the fuses against the data on Table 3.
NOTE:
Copper conductors must be installed between the
disconnect switch and the unit.
Refer to Figure 4 for the location of the power wire access
opening through the front of the unit. This opening will require
a field-supplied conduit fitting.
The field-supplied disconnect switch must be suitable for an
outdoor location. Although it should be installed near the unit,
do NOT secure it to the unit cabinet.
Spreaders, longer than the largest dimension
across the unit, MUST be used across the top of
the unit.
FIGURE 2 - TYPICAL RIGGING
Before lifting a unit, make sure that its weight is
distributed equally on the cables so that it will lift
evenly.
