is a leak in the refrigerant circuit:
▪ Do NOT use the unit's automatic pump down function, with which you can collect
all refrigerant from the system into the outdoor unit. Possible consequence: Selfcombustion and explosion of the compressor because of air going into the
operating compressor.
▪ Use a separate recovery system so that the unit's compressor does NOT have to
operate.
WARNING
ALWAYS recover the refrigerant. Do NOT release them directly into the environment.
Use a vacuum pump to evacuate the installation.
NOTICE
After all the piping has been connected, make sure there is no gas leak. Use nitrogen
to perform a gas leak detection.
NOTICE
▪ To avoid compressor breakdown, do NOT charge more than the specified amount
of refrigerant.
▪ When the refrigerant system is to be opened, refrigerant MUST be treated
according to the applicable legislation.
WARNING
Make sure there is no oxygen in the system. Refrigerant may only be charged after
