COMPRESSOR
Copeland Scroll Ultra Tech™ Two-Stage Compressor
G
Compressor features high
efciency with uniform
suction ow, constant
discharge ow and high
volumetric efciency and
quiet operation.
Compressor consists
of two involute spiral
scrolls matched together
to generate a series of
crescent shaped gas
pockets between them.
During compression, one
scroll remains stationary
while the other scroll
orbits around it.
Gas is drawn into the
outer pocket, the pocket
is sealed as the scroll
rotates.
As the spiral movement continues, gas pockets are
pushed to the center of the scrolls. Volume between the
pockets is simultaneously reduced.
When pocket reaches the center, gas is now at high
pressure and is forced out of a port located in the
center of the xed scrolls. During compression, several
pockets are compressed simultaneously resulting in a
smooth continuous compression cycle.
Continuous ank contact, maintained by centrifugal
force, minimizes gas leakage and maximizes efciency.
Scroll compressor is tolerant to the effects of slugging
and contaminants. If this occurs, scrolls separate,
allowing liquid or contaminants to be worked toward the
center and discharged.
On the xed scroll there
are two bypass ports in
the rst suction pocket. On
the outside of the xed
scroll there is a “slider
ring” that is controlled by
an internal solenoid that
will rotate and cover the
bypass ports. When the
thermostat calls for
rst-stage cooling, the
bypass ports are open and
the compressor operates
at 67% capacity, creating more cost-effective and
efcient compressor operation. The bypassed
refrigerant is returned to the compressor housing
through the bypass ports. When the thermostat calls for
second-stage cooling, the internal solenoid is energized,
the slider ring rotates and covers the bypass ports, and
the compressor operates at full capacity.
Low gas pulses during compression reduces
operational sound levels.

FEATURES
COMPRESSOR (CONTINUED)
Compressor motor is internally protected from
excessive current and temperature.
Compressor is installed in the unit on specially
formulated, resilient rubber mounts for better sound
dampening and vibration free operation.
Crankcase Heater
Crankcase heater prevents migration of liquid
refrigerant into compressor and ensures proper
compressor lubrication.
OPTIONS
Compressor Hard Start Kit
Single-phase units are equipped with a PSC
compressor motor.
This type of motor normally does not need a potential
relay and start capacitor.
In conditions such as low voltage, kit may be required to
increase the compressor starting torque.
Hard start kit is required in applications where the
supply voltage is less than 230V.

Low Ambient Kit
Air conditioner will operate satisfactorily down to 45°F
outdoor air temperature without any additional controls.
Kit can be added in the eld enabling unit to operate
properly down to 30°F.
A Freezestat should be installed on compressors
