Service Notes
1. All compressors have interchangeable valve
plate assemblies, unloader valves and oil pump
bearing head assemblies. For replacement items
use Carrier Specified Parts.
2. Before compressor is opened, the refrigerant
must be removed from it by the Pumpdown
method.
Start compressor, close suction shutoff
valve, and reduce crankcase pressure to 2
psig. (Jumper low pressurestat.)
Stop compressor and isolate from system by
closing discharge shutoff valve.
Bleed any residual refrigerant. Drain oil if
necessary.
