^ SAFETY CONSIDERATIONS
Installation, start-up and servicing of this equip­
ment can be hazardous due to system pressures,
electrical components and equipment location
(roofs, elevated structures, etc.).
Only trained, qualified installers and service
mechanics should install, start-up and service this
equipment.
Untrained personnel can perfonn basic main­
tenance functions of cleaning coils, cleaning and
replacing filters. All other operations should be
performed by trained service personnel.
When working on the equipment, observe pre­
cautions in the literature, tags, stickers and labels
attached to the equipment and to any other
safety precautions that apply.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Use care in handling, rigging and setting bulky
equipment.
WARNING; Be sure power to equipment is shut
off before performing maintenance or service.
INSTALLATION
Rigging — Preferred method is with spreader bars
from above the unit, utilizing the 4 eyebolts and
washers provided in fastener package (Table 3,
items 4, 5). Otherwise, rig with chains or cables
from above, using the eyebolts. Adjust cable or
chain length so that suspension angle with top of
unit is 45° or greater. If movement with rollers is
required, do not remove the unit from the skid
until it is in final position.
Placing Unit — Locate so condenser airflow is un­
restricted on all sides and on top (see Fig. 1 ).
Provide ample room for servicing cooler For re­
moval from compressor end, the 4-ft clearance
shown is sufficient for all units. For removal from
opposite end, see clearance dimension on Fig. 1.

bers are shipped in a cloth bag tied to one of the
compressor feet. Tighten all 4 bolts. Then loosen
each until the flanged washer can be moved side­
ways with finger pressure.
