Introduction YORK Air-Cooled Scroll Condensing Units are the perfect refrigeration com- ponents for all air conditioning applications that use DX central station air handling. They are designed for outdoor (roof or ground level) installation. Each unit includes hermetic scroll compressors, an air cooled condenser, and a weather resistant microprocessor control center, all mounted on a formed steel base.
REFRIGERANT CIRCUIT One (YCUL0016-0040) or two (YCUL0046-0130) inde- pendent refrigerant circuits will be finished on each unit. All unit piping will be copper, with brazed joints. The liquid line will include a field connection shutoff valve with charging port located on each condenser circuit.
