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 equipment.

These instructions cover installation of 30RAP010-060 air-cooled liquid chillers. Refer to Fig. 2 for model number to determine factory- installed options.

WARNING

Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation. There may be more than one disconnect switch. Tag all discon- nect locations to alert others not to restore power until work is completed.

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. 3 for unit weights. See Fig. 4 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.

CAUTION

All panels must be in place when rigging. Damage to unit could result.

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.
