INSTALLATION
Step 1 — Complete Pre-Installation Checks —
Examine for damage incurred during shipment. File claim
immediately with transit company if damage is found. Verify
that the nameplate electrical requirements match the available
power supply. Check the shipment for completeness.
Step 2 — Locate and Rig Unit, Remove Ship-
ping Skid
LOCATION — If roof installation is specified, make certain
that roof structure can support the condenser weight. Refer to
Table 1.
Locate condenser where an adequate supply of inlet outdoor
air is available. Do not locate where the possibility of air recir-
culation exists, such as under a roof overhang.
Locate condenser in an area free from airborne dirt or other
foreign material which could clog condenser coils.
RIGGING — Preferred method is with spreader bars from
above the unit. Use 2-in. (50 mm) OD pipe or hooks in lifting
holes. Rig with 4 cables and spreader bars. All panels must be
in place when rigging. See rigging label on unit for details con-
cerning shipping weights, distance between lifting holes, cen-
ter of gravity, and spreader bar dimensions. Also see Fig. 2.

If overhead rigging is not possible, place unit on skid or pad
for rolling or dragging. When rolling, use minimum of 3 roll-
ers. When dragging, pull the pad. Do not apply force to the
unit. When in final position, raise from above to lift unit off
pad.
All panels must be in place when rigging. Do not forklift
unit if no skid is supplied. If unit has skid, use forklift truck
from sides only.
PLACING UNIT — There must be 4 ft (1.22 m) for service
and for unrestricted airflow on all sides of unit, and a minimum
of 8 ft (2.44 m) clean air space above units. See Fig. 3, 4, and
5. For multiple units, allow 8 ft (2.44 m) separation between
units for airflow and service.
MOUNTING UNIT — When unit is in proper location, use
mounting holes in base rails for securing unit to supporting
structure. Fasteners for mounting unit must be field supplied. If
unit is to be mounted on vibration isolators, drill mounting
holes in bottom of base rail at support points 1-4 (shown in
Fig. 3, 4, and 5) and locate isolators at those points.
