2.0STANDARD FEATURES—5 TON SYSTEMS

2.1Evaporator Section—Split System

The evaporator section is designed for ceiling installation. The cabinet and chassis are constructed of heavy gauge galvanized steel. The unit can be serviced using only one side increasing its versatility in mounting locations. Mounting brackets are factory-attached to the cabinet. Internal cabinet insulation meets ASHRAE 62.1 requirements for Mold Growth, Humidity & Erosion, tested per UL 181 & ASTM 1338 standards. The evaporator section includes the evaporator coil, R-407C unit charge, filter-drier, factory-mounted disconnect switch, adjustable belt-drive blower assembly and microprocessor control with wall-mounted control box. The unit is provided with supply and return air openings for field-supplied ducting. Evaporators can be configured with canister humidifier and/or reheat. An indoor or outdoor condensing unit must be selected for each evaporator.

2.2Condensing Unit Section—Split System
