SAFETY CONSIDERATIONS

Installing and servicing air-conditioning equipment can be hazardous due to system pressure and electrical compo- nents. Only trained and qualified service personnel should install or service air-conditioning equipment.

Untrained personnel may perform basic maintenance such as cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe safety precautions in literature, and on tags and labels attached to unit.

Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for brazing operations. Have a fire extin- guisher available. Read these instructions thoroughly. Con- sult local building codes and National Electrical Code (NEC, U.S.A. Standard) for special installation requirements.

INSTALLATION

WARNING: Before installing or servicing system, always turn off main power to system. There may be more than one disconnect switch. Turn off accessory heater power if applicable. Electrical shock can cause personal injury.

I. COMPLETE PRE-INSTALLATION CHECKS

A. Unpack Unit

Move unit to final location. Remove unit packaging being careful not to damage service valves or grilles.

B. Inspect Shipment

File claim with shipping company if shipment is damaged or incomplete. Check unit nameplate to ensure unit matches job requirements.

C. Consider System Requirements

Consult local building codes and NEC for special installation requirements.

Allow sufficient space for airflow clearance, wiring, refriger- ant piping, and servicing unit. See Fig. 1 and 2. Unit can be mounted on a level pad directly on base legs or mounted on raised pads at support points. See Fig. 2 for center of gravity.
