SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning equip-
ment can be hazardous due to system pressures, electrical
components, and equipment location (roofs, elevated struc-
tures, etc.).
Only trained, qualified installers and service mechanics
should install, start up, and service this equipment (Fig. 1).
Untrained personnel can perform basic maintenance func-
tions such as cleaning coils. All other operations should be
performed by trained service personnel.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.
Follow all safety codes.
Wear safety glasses and work gloves.
Keep quenching cloth and fire extinguisher nearby when
brazing.
Use care in handling, rigging, and setting bulky

INSTALLATION
Step 1 — Rig and Place the Unit
RIGGING Preferred method for rigging is with spreader
bars from above the unit. Use hooks in lifting holes. Rig at a
single point with 4 cables or use spreader bars. All panels must
be in place when rigging. See rigging label on unit for details
concerning shipping weights, distance between lifting holes,
center of gravity, and lifting ring dimensions. See Tables 1A
and 1B for physical data. Refer to Fig. 2 for unit weights.
See Fig. 3 for rigging label.
If overhead rigging is not possible, place chiller on skid or
pad for rolling or dragging. When rolling, use a minimum of
3 rollers. When dragging, pull the pad. Do not apply force to
the unit. When in final position, raise from above to lift unit
off pad.
PLACING UNIT There must be at least 3 ft (0.9 m) for
service and for unrestricted airflow on all non-coil sides of unit,
and a minimum of 3.5 ft (1.1 m) clear air space on coil sides.
For multiple units, allow 8 ft (2.48 m) separation between units
for airflow and service.
MOUNTING UNIT When unit is in proper location, use
of mounting holes in base rails is recommended for securing
unit to supporting structure, or for mounting unit on vibration
isolators if required. See Fig. 3. Fasteners for mounting unit are
field supplied. Be sure unit is level to within
