amount of gas intake to the vacuum unit in
response to the operation of the Sullicon Control
(Par. 2.6).
The check valve prevents discharge gas and fluid
being drawn into the system and reverse running of
the vacuum unit during shutdown.
2.8 INSTRUMENTATION, FUNCTIONAL DESCRIP-
TION
Refer to Figure 2-5. The instrumentation of the
Vacuum System consists of a panel group which
will continually monitor the operating condition of
the machine.The gauges installed in the machine
are a fluid pressure gauge, discharge temperature
gauge, hourmeter, vacuum unit inlet vacuum
gauge, system vacuum gauge, separator mainte-
nance gauge and a fluid filter maintenance gauge.
• The system vacuum gauge continually
monitors the vacuum at various load and
unload conditions.
• The vacuum unit inlet vacuum gauge con-
tinually monitors the vacuum at various load
conditions and the condition of the inlet filter.
• The discharge temperature gauge moni-
tors the temperature of the vacuum unit dis-
charge gas/fluid. The normal reading should
be approximately 180ºF (82ºC) with 80ºF
(27ºC) ambient temperature.
• The hourmeter records cumulative hours of
operation for the vacuum unit and is useful
for planning logging service operations.
• The fluid pressure gauge continually mon-
itors the pressure at the vacuum unit bear-
