DESCRIPTION
These units are completely assembled, piped and wired at the
factory to provide one-piece shipment and rigging. Each unit is
pressurized with a holding charge of refrigerant-22 for storage
and/or shipping.
The compact design, clean styling, low silhouette, and quiet
operation make these condensing units suitable for almost any
outdoor location. On rooftops . . . because they weigh much less
than a single package unit of similar capacity and are much
easier to rig and support. At ground level . . . because their
ample sub-cooling capacity allows them to be located three or
more stories below the evaporator coil.
Every condenser coil is pressurized with air to 325 psig and
leak tested under water. After assembly, the unit is pressurized
with a combination of refrigerant-22 and nitrogen to 450 psig
for pressure testing and additional leak testing. During this
pressure test, the operation of the high pressure control is
checked. As the unit is being evacuated and dehydrated, the
operation of the low pressure control is checked. Every
compressor, condenser fan motor, crankcase heater, and
electrical control circuit is checked to assure a trouble-free
start-up and years of reliable operation.
The condenser fan guards are vinyl-coated to provide
additional rust protection and to enhance the appearance of
the unit.
Compressors are mounted on spring isolators in an enclosed
compartment to reduce the transmission of vibration and
sound. Vertical discharge condenser fans direct sound upward
and away from any surrounding structures.
All sheet metal parts are constructed of commercial grade
(G90) galvanized steel. After fabrication, each part is
thoroughly cleaned to remove any grease or dirt from its
surfaces. The external parts are coated with a ‘‘desert sand’’
powder paint to assure a quality finish for many years. This UL
approved coating system has passed the 750 hour, 20% salt
spray test per ASTM Standard B117.
All models include a 1-year limited warranty on the complete
unit. An additional 4-year extended compressor warranty is
available as an option on all models.
A matching line of Evaporator Blower units is also offered to
meet your precise capacity and air handling requirements.
Refer to Form 550.13-TG2 for more information on this air side
equipment.
FEATURES
• Copeland “Discus” semi-hermetic compressors provide
both high efficiency 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 controls
are self-contained, there are no capillary lines to be
damaged.
Solid state motor protection. The module also provides both
low voltage and anti-short cycle protection.
Class 2, 24-volt thermostat control circuit.
550.13-TG1Y
• A filter-drier is shipped in the unit’s compressor compartment for
•
•
field installation in the liquid line near the evaporator coil. Two
are provided on all 40 and 50 ton models.
Suction, liquid and discharge line service valves. Each valve
has a back-seating access port for pressure testing the
system. 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 0°F. Refer to page 11 for a
typical condenser fan motor operating sequence. Some
units will have more or fewer condenser fans, but the
sequence of operation will be similar.

•
• Capacity reduction for more economical operation and more
even temperature levels within the conditioned space.
After 10 or 15 short “ON” and “OFF” cycles in succession,
there may be enough refrigerant mixed with the crankcase
oil to cause the oil to foam when the compressor starts up
and to be pumped out of the compressor. If the oil level drops
below the suction intake to the oil pump, the oil pressure will
drop and the oil failure switch will shut down the compressor.
• Part-winding-start on 208/230 volt units. A time delay relay
reduces the inrush current at start-up by preventing both

With pumpdown, a solenoid valve will close the liquid line
when the cooling requirement has been satisfied to prevent
any refrigerant from feeding through the expansion valve
when the system shuts down. Since the compressor will
continue to run until it is shut down by a low pressure cutout,
the evaporator coil should be relatively dry when the liquid
line solenoid valve reopens. Although the expansion valve
will overfeed the evaporator coil when the system starts up,
all of the refrigerant will evaporate before it reaches the
compressor.

same time.
• A 7/8" spud connection on the discharge header of the
•
control during start-up. This prevents nuisance tripping at low
ambient conditions.
A low oil-pressure control with manual reset for additional
compressor protection.
A lockout circuit to prevent the unit from cycling on safety
control.
Non-recycling pumpdown. Without pumpdown, the
expansion valve will overfeed each time the system starts
up and shuts down. This excess refrigerant will accumulate
in the crankcase of the compressor and will mix with the
crankcase oil. If the “ON” cycles are short, the refrigerant will
not have a chance to separate from the oil gradually. If the
“OFF” cycles are short, the operation of the crankcase
heater will be ineffective.

Refer to Form 550.13-N6 for additional information.
A timer in each compressor circuit providing anti-short-cycle
protection and a bypass around the system’s low pressure

During low ambient conditions, one of the fan motors (two motors on the CA480 and CA600) will operate at 450 RPM.
3
These PSC motors are directly connected to the condenser fans and have inherent protection, ball bearings and a 48 frame. Their rotation is clockwise when viewing the shaft end of
the motor.
Based on a 115°F ambient temperature.

TYPICAL CONDENSER FAN MOTOR
The #3 condenser fan motor is controlled
by both ambient temperature and system
capacity. At full compressor, a control relay
will keep it energized at any ambient
temperature. At less than full compressor,
an outdoor thermostat will lock it out below
75°F.
The #4 condenser fan motor is controlled by
compressor discharge pressure. When the
pressure drops below 180 psig, the motor
will be powered through a choke coil and its
