COMPRESSOR

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 the pocket reaches the center, gas is now at high
pressure and is forced out of a port located in the center
RIWKH¿[HGVFUROOV
During compression, several pockets are compressed
simultaneously resulting in a smooth continuous
compression cycle.
&RQWLQXRXVÀDQNFRQWDFWPDLQWDLQHGE\FHQWULIXJDO
IRUFHPLQLPL]HVJDVOHDNDJHDQGPD[LPL]HVHI¿FLHQF\
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.
Low gas pulses during compression reduces
operational sound levels.
Compressor motor is internally protected from
excessive current and temperature.
Compressor is installed in the unit on specially
formulated, resilient rubber base for improved sound
dampening and vibration-free operation resulting in
quieter operating sound levels. See Outdoor Sound
Data table for details.
Compressor Crankcase Heater (060 Models)
Protects against refrigerant migration that can occur
during low ambient operation.
Factory Installed.
Compressor Sound Dampening System

Optional Accessories
Compressor Crankcase Heater (018 thru 048
models)
Protects against refrigerant migration that can occur
during low ambient operation.
Compressor Hard Start Kit
Single-phase units are equipped with a PSC
compressor motor. This type of motor normally doesn’t
need a potential relay and start capacitor.
In conditions such as low voltage, this kit may be
required to increase the compressor starting torque.
Compressor Low Ambient Cut-Off Switch
Non-adjustable switch (low ambient cut-out) prevents
compressor operation when outdoor temperature is
below 35°F.
CONTROLS
Optional Accessories
Indoor Blower Off Delay Relay
Delays the indoor blower-off time during the cooling
cycle.
See AHRI System Matches for usage.
Low Ambient Kit
Air conditioners operate satisfactorily down to 45°F
outdoor air temperature without any additional controls.
/RZ$PELHQW&RQWURO.LWFDQEH¿HOGLQVWDOOHGDOORZLQJ
unit operation down to 30°F.
Crankcase heater and freezestat should be installed on
compressors equipped with a Low Ambient Kit.
A compressor lock-out thermostat should be added to
terminate compressor operation below recommended
operation conditions
Thermostat
Thermostat not furnished with unit. See Thermostat
bulletins in Controls Section and Lennox Price Book.
Compressor Timed-Off Control
Kit prevents compressor short-cycling and allows time
for suction and discharge pressure to equalize.
Permits compressor start-up in an unloaded condition.
Automatic reset with 5 minute delay between
compressor shut-off and start-up.
