permit the piston to suck and
compressor the which consequentely
dose not circulate in the system.
and then proceed
with refilling.
Noisy
motor-comp
ressor
In case of mechanical failure in the
motor-compressor there in an excessive
noise when the system is functioning in
case a suspension spring is unhooked
banging will be heard and there will be
especially strong vibrations when the
system starts up and stops.
The cause of the excessive noise is
normally to be sought for in a
mechanical break down and only
rarely in the unhooking of one of the
suspension springs.
The
motor-compressor
must be substituted
and then proceed
。
