consequences are reduced performance and a higher
discharge gas temperature.

9 Decommissioning

9.1 Standstill

Leave the oil heater switched on until disassembly.
This prevents increased refrigerant concentration in the
oil.
WARNING
Risk of refrigerant evaporation from the oil.
Increased risk of flammability, depending on the
refrigerant!
Shut-down compressors or used oil may still
contain rather high amounts of dissolved refri-
gerant.
Close the shut-off valves on the compressor
and extract the refrigerant!

9.2 Dismantling the compressor

WARNING
The compressor is under pressure!
Serious injuries are possible.
Depressurize the compressor!
Wear safety goggles!
Close the shut-off valves on the compressor. Extract
the refrigerant. Do not deflate the refrigerant, but dis-
pose of it properly!
Loosen screwed joints or flanges on the compressor
valves. Remove the compressor from the system; use
hoisting equipment if necessary.
9.2.1

Disposing of the compressor

Drain the oil from the compressor. Dispose of waste oil
properly! Have the compressor repaired or dispose of it
properly!
When returning compressors that have been operated
with flammable refrigerant, mark the compressor with
the symbol "Caution flammable gas", as the oil may still
contain refrigerant.
