• 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 separator maintenance gauge moni-
tors the condition of the separator element
(s) and indicates when the element restric-
tion is excessive.
• The system vacuum gauge continually
monitors the vacuum at various load and
unload conditions.
• The unit vacuum inlet gauge continually
monitors the vacuum at various load condi-
tions along with the condition of the inlet fil-
ter (done by comparing the vacuum differ-
ential between the two vacuum gauges).
• The fluid pressure gauge continually mon-
itors the pressure at the vacuum unit injec-
tion.
• The fluid filter maintenance gauge moni-
tors the condition of the fluid filter element
and indicates when the element(s) should
be changed.
