If applicable. See the installation manual or installer reference guide of your
application for more information.
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.
WARNING
During tests, NEVER pressurise the product with a pressure higher than the
maximum allowable pressure (as indicated on the nameplate of the unit).
