FEATURES
•
Copeland Scroll compressors provide both high effi-
ciency and reliability.
•
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.
•
A sight glass and filter-drier is shipped in the unit's con-
trol box for field installation in the liquid line near the
evaporator coil. Two are provided on all 30, 40 and 50
ton models.
•
Copper stub-outs are factory mounted on the suction
and liquid lines to simplify the field piping connections.
•
Multiple controls to provide stable system operation at
ambient temperatures down to 40ºF.
•
Capacity reduction 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.
•
Pumpout on unit startup to prevent allowing liquid refrig-
erant returning to the compressor.
*Rated in accordance with ARI Standard 360 (60 Hz).
EER = Energy Efficiency Ratio at full load - the cooling capacity in Btu’s
per hour (Btuh) divided by the power input in watts, expressed in Btuh per
watt (Btuh/watt).
