Water Removal
Water vapor may condense in the reservoir
and must be removed. The frequency
with which water must be removed is
determined by the ambient air conditions.
During hot and humid conditions, water
should be drained off the bottom of the
reservoir daily. In cold and dry conditions,
water may only need to be drained weekly.
To drain water from the reservoir, turn
the compressor off and let sit for at least
5 minutes. Then open the drain valve.
Water is heavier than the compressor
fluid and will collect at the bottom of the
reservoir. When the drain is first opened
some compressor fluid may come out
before the water starts to flow. Close
the valve when the water flow changes
to compressor fluid. Make certain that
there is no pressure in the reservoir before
opening the drain valve. Water content in
the compressor fluid in excess of 200 PPM
could cause bearing damage and airend
failure.
Air/Fluid Separator Elements
The air fluid separator element should be
replaced as indicated in the maintenance
schedule or as follows:
If excessive fluid carryover is observed.
Every 4000 running hours.
Once a year.
Continuity Testing of Separator Elements
notiCe!
Electrical continuity between all
separator element metal surfaces
must be checked prior to replacing
any separator element. Do not install
if continuity is not present. Return
the separator element to your Quincy
Distributor for replacement.
Prior to installation, test the separator
element as follows:
) Locate a continuity test light or a
volt-ohm-meter (v-o-m) capable of
reading 20 ohms.
2) Assure that battery has proper
charge. Touch the probe leads
together to assure the light works or
♦
♦
♦
to zero calibrate the meter.
3) Contact the grounding spring clip
on the separator element gasket
with the ground probe of the test
indicator.
4) Touch the top cap of the separator
element with the other probe. The
indicator light should illuminate on
the test or the v-o-m test must read
no more than 20 ohms.
5) Touch the bottom cap of the
separator element. The indicator
light should illuminate on the test or
the v-o-m test must read no more
than 20 ohms.
6) Touch the outside wire mesh. The
indicator light should illuminate on
the test or the v-o-m test must read
no more than 20 ohms.
7) Touch the inside wire mesh ( do not
puncture the element media). The
indicator light should illuminate on
the test or the v-o-m test must read
no more than 20 ohms.
8) If the separator element fails any
of the above test , return it to your
Quincy Distributor for replacement.
9) Make sure the compressor is bonded
(wired) to an earth ground to
dissipate static electricity.
