These heat pump systems provide economy of operation through energy conservation. They recover heat for indoor comfort from outdoor air during the heating season and, by automatically reversing the refrigerant system, remove indoor heat and excess humidity during the cooling season. All models are listed with UL, CSA, CEC and ARI. FEATURES ELECTRICAL RANGE—All single-phase units are offered in 208/230 volts. Three-phase available in both 208/230 and 460 volt. COMPRESSOR—Designed specifically for heat pump duty, with energy efficiency during heating and cooling operation. Each compressor is hermetically sealed against contamination to assure long life and dependable performance, internally sprung and externally mounted on rubber isolators for quiet operation. Continuous compressor operation is approved down to -30°F (-34.4°C) in the heating mode, and down to 55°F (12.8°C) in the cooling mode. (See heating and cooling performance tables.) All models include a discharge-tube muffler to prevent sound transmission of the compressor pulsations to the indoor or outdoor coils. BUILT-IN-RELIABILITY COMPONENTS—Includes a suction-tube accumulator that keeps liquid refrigerant from reaching the compressor; a low-pressure switch that stops the compressor if refrigerant charge is lost; a crankcase heater to keep the compressor oil warm and free of refrigerant for maximum lubricity; an internal compressor relief valve for high-pressure protection; and compressor start capacitor and relay components on single-phase units to assure reliable starting of the units during brownout conditions and low outdoor temperatures. DEFROST CONTROL BOARD—Incorporates a defrost relay, defrost timer, and low-voltage terminal board. The defrost control is a time/temperature initiation/termination control which includes three field-selectable time periods of 30, 50, and 90 minutes. WEATHER-PROTECTIVE CABINET—Steel is protected with a heavy coating commonly called “galvanizing,” then coated with a layer of zinc phosphate to which a coat of modified polyester powder coating is applied and baked-on. This provides each unit with a hard, smooth finish that will last for many years. All screws on cabinet exterior are coated for a long-lasting rust-resistant, quality appearance. UNIT DESIGN—All units are equipped with totally enclosed fan motors for greater reliability under rain and snow conditions. (Ball bearing fan motors standard on 3 phase units.) The large, wraparound coil uses copper tube and enhanced aluminum fin and is designed for optimum heat transfer during heating and cooling. The vertical air discharge carries the sound and air up and away from adjacent patio areas and foliage. Sufficient space is provided between rows of composite coils so they can be cleaned with a common garden hose. EXTERNAL SERVICE VALVES—Both service valves are brass, back seating type with sweat connections. Each valve has a service port for ease of checking operating refrigerant pressures. PDS No. 690A.14.5B AIR DISCHARGE NOTES: 1. ALLOW 2’-6" (762) CLEARANCE TO SERVICE END OF UNIT, 4'-0" (1219) ABOVE UNIT, 6" (152) ON ONE SIDE, 1'-0” (305) ON REMAINING SIDE, AND 2'-0” (610) BETWEEN UNITS FOR PROPER AIRFLOW. 2. MINIMUM OUTDOOR OPERATING AMBIENT IN COOLING MODE IS 55®F (12.8°C), (UNLESS LOW AMBIENT CONTROL IS USED). MAXIMUM 12S°F (51.7#C). 3/8"D. (9.5) KNOCKOUTS (2) PLACES \ v*3 'O'--.
