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.

Before installing or servicing system, always turn off main power to system. There may be more than one dis- connect switch. Turn off accessory heater power if appli- cable. 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 installa- tion of the complete system. Note that the outdoor units are shipped with installation and service instructions for basic in- stallation of the outdoor section. Be sure to make the connec- tions in Cooling Only Systems and Heat Pump Systems sec- tions on page 15 of this literature so that the unit will operate properly.

Refer to Table 1 for proper system matches.
