De-commissioning
Standstill
Keep the crankcase heater switched on until dismantling the compressor. This prevents
increased refrigerant concentration in the compressor oil.
Dismantling the compressor
For repair work that makes compressor removal necessary, or when decommissioning:
1. Close the shut-off valves at the compressor.
2. Reclaim the refrigerant. Do not release refrigerant into the atmosphere. Follow all
federal regulations.
3. Open the threaded joints or flanges at the compressor valves.
4. Remove the compressor if necessary with a hoisting tool.
Compressor Disposal
Drain the oil out of the compressor. Dispose of waste oil properly. Chlorinated oil is a
pollutant. Have the compressor repaired or disposed of per federal regulations.
