SAFETY CONSIDERATIONS

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

Untrained personnel can 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 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 fire extinguisher available. Read these instructions thoroughly. Consult local building codes and National Electrical Code (NEC) for special installation requirements.

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.

INSTALLATION

Installation instructions for fan coil units (Fig. 1) are con- tained in this manual. Refer to this manual for proper instal- lation of the complete system. Note that the outdoor units are shipped with installation and service instructions for basic installation of the outdoor section. Be sure to make the con- nections in Cooling Only Systems and Heat Pump Systems sections on page 15 of this literature so that the unit will operate properly.

Refer to Table 1 for proper system matches.
