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
field installation in the liquid line near the condensing
unit.
• Copper stub-outs are factory mounted on the suction
and liquid line service valves to simplify the field piping
connections.
• Multiple controls to provide stable system operation at
ambient temperatures down to 40ºF with kits available
for operation to 0ºF.
• Capacity staging for more economical operation and
more even temperature levels within the conditioned
space.
• A lockout circuit to prevent the unit from cycling on safety
control.
• 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.
• Factory installed disconnect and Technicoat coils option.
• Self contained high and low pressure controls.
Condensing Unit Accessories
• Low ambient VFD control to 0° F.
• Phase Monitors - Designed to prevent unit damage. The
phase monitor will shut the unit down and out-of phase
condition.
• Hot Gas Bypass Kit - That will provide a metered flow of
compressor discharge gas to the system’s evaporator
coil during reduced load operation.
• Optional skid for fork truck handling (requires 96” length
forks).
