2-4. OPERATING UNDER USUAL CONDITIONS (Continued).
TO START
Unusually high reading on
pressure gauges may indicate
improper startup procedures.
A.
Place auto controls selector
switch in ON position.
B.
Place supply pump selector
switch in the ON position.
The system is now operating
in automatic mode.
Oil ex-
tracted from the water will
be automatically discharged
from the first (prefilter)
and second stage separators
when sufficient oil has
accumulated in the top of
each vessel to cover the
mini-probe.
If oil is
observed in the sight glass
of the third stage vessel,
it is removed manually by
opening the oil discharge
valve.
The presence of
oil in the third stage
vessel, as observed in
the sight glass could be
an indication of a ruptured
filter coalescer element
in the second stage or
leakage around seals at
either end of the element.
