Condensing Unit Features and Benefits
•
Meets or exceeds ASHRAE 90.1 standards.
•
Scroll compressors provide both high efficiency and reli-
ability.
®
•
Simplicity
SE Controls
•
Dual refrigerant circuits.
•
Condenser coils are constructed of copper tubes and
aluminum fins for durability and long lasting efficient
operation.
•
Crankcase heaters that will be de-energized when the
compressor is operating.
•
Both high and low pressure controls. Since these con-
trols are self-contained, there are no capillary lines to be
damaged.
•
Solid state or internal line break compressor motor pro-
tection.
•
Class 2, 24-volt thermostat control circuit.
•
Factory installed service valves are standard.
•
Two filter-driers are shipped in the unit's control box for

•
Pump-out on unit startup to prevent liquid refrigerant
returning to the compressor is standard on all models.
•
Inherently protected condenser fan motors.
•
V-Coil Design with exterior service port connections.
•
Five-minute anti-short cycle timer and minimum com-
pressor run time.
