9.6 Additional information when using flammable refrigerants
WARNING
• During maintenance and repair, it must be noted that hydrocarbon
and synthetic HFO refrigerants residues may dissolve in the
oil. Therefore, electrical tests must not be conducted while oil
remains in the compressor.
• If the compressor is to be removed from the system for
maintenance or repair, the remaining refrigerant must be
suctioned out and the compressor evacuated. The compressor
must then be filled with nitrogen (max. 0.5 bar) and sealed
gas-tight.
