25.4.2 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.
