Used oil from systems with A3 or A2L refrigerants

Fire hazard!

Fire hazard!

The used oil contains a relatively large amount of dissolved refrigerant.

Pack used oil safely. Dispose of in an environmentally friendly manner.

  1. Hydrocarbons, for example propane, R290 or propene, R1270 and low-fluorinated flammable refrigerants, for example R1234yf, dissolve very well in refrigeration compressor oil at room temperature. This also applies to blends containing these substances.
  2. Used oil from such systems may still contain relatively high percentages of dissolved flammable gases even at atmospheric pressure. These components gas out.
  3. Observe during storage and transport:
  1. Fill used oil into pressure resistant vessels.
  2. Fill vessels with nitrogen as a protective gas and close them.
  3. Mark them, e. g. with the warning sign "flammable substance" W021 from ISO7010.
