FEATURES SCROLL COMPRESSOR Compressor features high efficiency with uniform suction flow, constant discharge flow and high volumetric efficiency 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 fixed scrolls. During compression, several pockets are compressed simultaneously resulting in a smooth continuous compression cycle. Continuous flank contact, maintained by centrifugal force, minimizes gas leakage and maximizes efficiency. Scroll compressor is tolerant to the effects of slugging and contaminants. If this occurs, scrolls separate, allowing liquid or contaminants to 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 resilient rubber mounts for vibration free operation. Optional Accessories Compressor Crankcase Heater 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 Timed-Off Control 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. CABINET Conditioned areas insulated with foil faced insulation to minimize heat loss and reduce operating sound levels. Powder paint for maximum durability. Easy service access. Steel louvered panels provides complete coil protection. Airflow Choice Units are shipped in horizontal configuration and can be field converted to downflow (vertical) airflow with optional Downflow Conversion Kit. Electrical Inlets and Service Valves Field wiring inlets are located in one central area of the cabinet. See dimension drawing. Gauge ports are located inside the cabinet. Optional Accessories Downflow Conversion Kit Required for field conversion to downflow (vertical) air. Kit consists of duct covers to block off horizontal air openings on side of unit. Kit also includes drain pan overflow switch to monitor condensate level in drain pan, shuts down unit if drain becomes clogged. Lifting Brackets Available to facilitate rigging of the unit. Clip Curb (Full Perimeter) Mates to unit. Roof curb can be assembled using interlocking tabs to fasten corners together. No tools required. Available in 8 and 4 inch heights. Shipped knocked down. Adjustable Pitch Roof Curb (Full Perimeter) Fully adjustable pitch curb provides a level platform for packaged units allowing flexible installations on roofs with sloped or uneven angles. Adjustable from / to 6/ pitch. Unit hold-down brackets secure packaged unit to curb. Constructed of heavy-gauge galvanized steel with fully welded seams and corners. Rounded corners on flange prevent damage to roof shingles. Built-in drip edge. IAPMO/UMC listed. CBC 03 compliant (California). Seismic rating - Ss=3.73 Ip=.5, wind rating - 55mph.
