38YCC (60 Hz) 10 SEER Heat Pump Export Model Sizes 18 --- 60 (1---1/2 to5 Nominal Tons) Product Data The 38YCC Outdoor Section of Split--System Heat Pumps is designed for quiet, reliable heating during the winter and cooling during the summer. With EER ratings up to 9.5, this heat pump system provides economy of operation through energy conservation when used with components designated by the manufacturer. The 38YCC recovers heat for indoor comfort from outdoor air during the heating season and, by automatically reversing the refrigerant system, removes indoor heat and excess humidity during the cooling season. All models are listed with UL (U.S. and Canada). FEATURES AND BENEFITS Electrical Range All units are offered in 208/230v single phase. Three--phase units are available from 036 through 060 sizes in 208/230v. Wide Range of Sizes All sizes of the 38YCC are offered in single phase 208--230v. The 38YCC 030 through 060 models are offered in 208/230v 3 phase. Unit Design All units are equipped with totally enclosed fan motors for greater reliability under adverse weather conditions. The large, wrap--around coil uses copper tube epoxy coated enhanced aluminum fin and is designed for optimum heat transfer and corrosion protection during heating and cooling. The vertical air discharge carries the sound and air up and away from adjacent patio areas and foliage. Coil can be cleaned with a common garden hose. WeatherArmort Cabinet A weather protective cabinet of pre--painted steel is protected underneath by a zinc galvanized coating for a finish that will last for many years. All screws on cabinet exterior are coated for a long--lasting, rust--resistant, quality appearance. 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; compressors are also externally mounted on rubber isolators for quiet operation. For improved serviceability, all models are equipped with a compressor terminal plug. 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 (unless equipped for low--ambient operation). Compressor Protection Each compressor is protected with internal temperature-- and current--sensitive overloads. Reliable standard components Includes a suction--tube accumulator that reduces the amount of liquid refrigerant that reaches the compressor; a lowpressure switch to stop the compressor if refrigerant charge is lost; a crankcase heater on all 3--phase units (except 030 size) to keep compressor oil warm and free of refrigerant for maximum lubricity; an internal compressor relief valve for high--pressure protection. 3--phase monitor board (scroll compressor models) Control board that monitors the electrical phase and prevents compressor operation if wired incorrectly.
