Compressor holding
charge
Each compressor is shipped with a nominal dry
nitrogen holding charge between 0.3 and 0.7 bar
and is sealed with elastomer plugs.
Before the suction and discharge plugs are re-
moved, the nitrogen holding charge must be
released via the suction schrader valve to avoid
an oil mist blowout. Remove the suction plug
fi rst and the discharge plug afterwards. The plugs
shall be removed only just before connecting the
compressor to the installation in order to avoid
moisture from entering the compressor. When
the plugs are removed, it is essential to keep the
compressor in an upright position so as to avoid
oil spillage.
INSTALLATION
Mounting of SH180-240-300
and 380
Compressors SH180-240-300-380 come deliv-
ered with rigid mounting spacers for parallel
mounting.
If used in single applications, the compressor
must be mounted with the fl exible grommets
as available in accessory conversion kit 8156138.
The grommets must be compressed until contact
between the fl at washer and the steel mounting
sleeve is established. The grommets attenuate to
a great extent the transmission of compressor vi-
brations to the base frame.
The required bolt size for the SH180 – 240 - 300
- 380 compressors is HM8-55. This bolt must be
tightened to a torque of 21 Nm.
