SAFETY CONSIDERATIONS

Installing, starting up, and servicing air-conditioning equip-

ment can be hazardous due to system pressures, electrical com-

ponents, and equipment location (roofs, elevated structures,

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 per-

formed 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

equipment.

• See Tables 1A and 1B for Physical Data.

INSTALLATION

Step 1 — Rig and Place the Unit

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, center

of gravity, and spreader bar dimensions. See Fig. 2.

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 4 ft (1.2 m) for

service and for unrestricted airflow on all sides of unit, and a

minimum of 8 ft (2.4 m) clear air space above unit. Provide

ample room for servicing cooler. For cooler removal see clear-

ance requirements in Fig. 3-5. For multiple units, allow 8 ft

(2.4 m) separation between units for airflow and service.

If unit is to be used in an area with high solar radiation,

mounted position should be such that control box is not ex-

posed to direct solar radiation. Exposure to direct solar radia-

tion could affect the temperature switch controlling cooler

heaters. See Table 2.

ELECTRIC SHOCK HAZARD

Open all remote disconnects before servicing

this equipment.

All panels must be in place when rigging.
