COOLING SYSTEM Scroll Compressor Operation

• Two involute spiral scrolls matched together generate a
R-410A Refrigerant series of crescent-shaped gas pockets between them
• Non-chlorine based
• During compression, one scroll remains stationary while
• Ozone-friendly the other scroll orbits around it
• Factory pre-charged • Gas is drawn into the outer pocket, the pocket is sealed
Evaporator and Condenser Coils as the scroll rotates
• Copper tube with aluminum fin coils • As the spiral movement continues, gas pockets are
• Factory leak tested pushed to the center of the scrolls. Volume between the
pockets is simultaneously reduced
Anti-Microbial Condensate Drain Pan • When the pocket reaches the center, gas is now at high
• Anti-Microbial additive resists growth of mold and pressure and is forced out of a port located in the center
mildew on drain pan which improves indoor air quality of the fixed scrolls
and reduces drain line blockage
• During compression, several pockets are compressed
• Insulated to reduce condensation simultaneously resulting in a smooth continuous
• Side drain connection compression cycle
Drain Pan Overflow Switch • Continuous flank contact, maintained by centrifugal
force, minimizes gas leakage and maximizes efficiency
• Monitors condensate level in drain pan
• Compressor is tolerant to the effects of slugging and
• Shuts down unit if drain becomes clogged

Outdoor Coil Fan Motor liquid or contaminants to be worked toward the center
• Weather protected heavy duty condenser fan motor and discharged
• Coated steel fan blades for long life • Muffler in discharge line reduces operating sound levels
• Corrosion-resistant coated steel fan guard Optional Accessories
• Internally mounted Field Installed
• Totally enclosed fan motor Compressor Crankcase Heater
High Pressure Switch • Protects against refrigerant migration that can occur
• Protects the system from high pressure conditions during low ambient operation
• Automatic reset. Compressor Timed-Off Control
• Prevents compressor short-cycling
Loss of Charge Switch
• Shuts off unit if suction pressure falls below setting • Allows time for suction and discharge pressure to
equalize
• Loss of charge and freeze-up protection
• Permits compressor start-up in an unloaded condition
Service Valves • Automatic reset
• Fully serviceable brass valves installed in discharge &
liquid lines • Five minute delay between compressor shut-off and
