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.

ELECTRIC SHOCK HAZARD
Separate power sources (main and control
power circuits) are used for these units. Be
sure both main and control power circuits are
disconnected before servicing.

INSTALLATION

Step 1 — Complete Pre-Installation Checks

UNCRATE UNIT — Remove unit packaging except for the
top skid assembly, which should be left in place until after
the unit is rigged into its final location.

INSPECT SHIPMENT — File claim with shipping com-
pany if shipment is damaged or incomplete.

CONSIDER SYSTEM REQUIREMENTS
• Consult local building codes and National Electrical Code

(NEC, U.S.A.) for special installation requirements.

• Allow sufficient space for airflow clearance, wiring, re-

frigerant piping, and servicing unit. See Fig. 1. See
Fig. 2 for unit component locations.

• Locate unit so that outdoor coil (condenser) airflow is un-

restricted on all sides and above.

• Unit may be mounted on a level pad directly on the base

channels or mounted on raised pads at support points. See
Table 1A-1D for unit operating weights. See Table 2 for
weight distribution based on recommended support points.
NOTE: If vibration isolators are required for a particular
installation, use the data in Table 2 to make the proper
selection.
