22.2.2 To recover refrigerant
This should be done with a refrigerant recovery unit. Follow the same procedure as
for vacuuming method.
DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump down the system, and there
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: Self-
combustion 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.
NOTICE
Make sure to NOT recover any oil while recovering refrigerant. Example: By using an
oil separator.
