CompressorsCompressor Arrangement, Sizes & Notes

Compressor Sizes Used in Each Unit

Note that there are two versions of Compressors used in ALS "B" vintage units. The first design is Liquid Cooled (cooled by refrigerant). The second version is cooled by oil.Oil Cooled Compressor equipped units (as shown in the picture to the left) include an Oil Separator, external Oil Filter, Oil Switch, Oil Pressure Control, and Valving not used in the Liquid Cooled design.Since the piping layout differs between Liquid and Oil cooled Compressors, it is very important to visually confirm which type of compressor is in the unit BEFORE ordering a replacement.

Unit PipingBasic Information

Each unit has three separate lines on each circuit: Suction, Discharge and Liquid. As an option, a unit may also have Hot Gas Bypass on just Circuit One, or on Circuits One and Two (never just on Circuit Two, and never on Circuit Three). The charts on the following pages list only the primary replace-ment components. Because of the many possible piping arrangements we have not listed all of the individual tubes in these tables. To identify a part not listed, contact Daikin Applied with the unit GO and Serial Numbers.
