Evaporator Section - Split Systems

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 and ASTM 1338 standards.
The evaporator section includes the evaporator coil, R-407C unit charge, filter-drier, factory-mounted
disconnect switch, two-speed direct-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 or supply/return plenum. Evaporators can be configured with canister humidifier and/or
reheat. An indoor or outdoor condensing unit must be selected for each evaporator.
2.2 Condensing Unit Section—Split Systems
2.2.1

Indoor Centrifugal Fan Condensing Units

Indoor Air-Cooled Centrifugal Fan Condensing Units include scroll compressor, factory-mounted
disconnect switch, condenser coil, R-407C unit charge, belt-driven centrifugal blower assembly,
high-pressure switch, Liebert Lee-Temp
line solenoid valve. Unit must be mounted indoors. Condensing unit is designed to use outdoor air
with temperatures ranging from -30°F to 95°F (-34°C to 35°C).
2.2.2

Outdoor Prop Fan Condensing Units

Outdoor Prop Fan Condensing Units include scroll compressor, condenser coil, R-407C unit charge,
prop fan, liquid-line solenoid valve, high pressure switch, Liebert Lee-Temp head pressure control
and hot gas bypass. Condensing unit is designed for outdoor locations with operating ambients
ranging from -30°F to 95°F (-34°C to 35°C).
2.2.3

Indoor Water/Glycol Condensing Units

Indoor Water/Glycol Condensing Units includes scroll compressor, R-407C unit charge,
factory-mounted disconnect, coaxial condenser, hot gas bypass, high head pressure switch and
two-way water regulating valve designed for 150psi (1034.3kPa). Condensing units can be used on
either a water or glycol cooling loop.
2.3

Chilled Water Units

Chilled Water Units are 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 and ASTM 1338 standards. Chilled water models are self-contained and include a chilled
water coil, two-speed, direct-drive centrifugal blower, factory-mounted disconnect switch and two-
way, slow-close motorized valve. Design pressure is 300psi (2068kPa), 60psi (414kPa) close-off
differential.
