4.3 Connecting the pipelines

WARNING
The compressor is subject to excess pressure
through holding charge.
Risk of injury to skin and eyes.
Wear safety goggles when working on the com-
pressor! Do not open the connections before ex-
cess pressure has been relieved. Pull out the
rubber plugs of the connections, thus relieving
the compressor of pressure.
NOTICE

Potential chemical reactions due to air penetra-
tion!
Avoid prolonged air penetration into the com-
