NOTICE–Maintenance should only be performed by
trained and qualified technicians.
Safety procedures performed while servicing the
compressor are important to both the semice persomel
at the time of servicing and to those who maybe around
the compressor and the system it serves. Listed below
are some procedures, but not all, that should be
followed:
. Wait for the unit to cool before starting service.
Temperatures may exceed 180° F when the compressor
is operating.
o Cleanup fluid spills immediately to prevent slipping.
oLoosen, but do not remove, flange or component
bolting. Then, carefidly pry apart to be sure there is
no residual pressure before removing the bolting.
. Never use a flammable solvent such as gasoline or
kerosene for cleaning air filters or compressor parts.
Safety solvents are available and should be used in
accordance with their instructions.
oImproper disassembly will result in damage to the
compressor or injure personnel. Use the correct tools,
torque bolts to their correct value and utilize good
shop practices.
! CAUTION!
Unusual noise or vibration indicates a problem.
Do not operate the compressor until the source
has been identified and corrected.
Lubricatin~ and Coolin~ Fluid
Each unit comes equipped with a fluid level sight
gauge, a fluid fill opening located on the side of the
45
airhluid reservoir and a fluid drain located at the
bottom of the reservoir. The fill plug is drilled to
allow some pressure to escape before the plug is
completely removed. Should you hear pressurized
air venting through this hole, immediately screw the
plug back into the reservoir and relieve the pressure
in the reservoir before proceeding. Each unit is
factory filled with QUINSIW synthetic fluid or
QUINSYIW F (food grade) synthetic fluid. Mineral
oil can be requested and used in specific applications.
The use of other brands or types of lubricant may
reduce the design life of the compressor or cause
problems with filtration or carryover. Consult the
Quiney facto~ before changing brands or types of
lubricating, cooling fluid.
!J)ANGER!
Hot fluid under pressure will cause severe injury
or death. Do not remove the fluid fill plug nor
attempt to add fluid to the air/fluid reservoir
while the compressor is in operation or when the
air/fluid reservoir is under pressure. Be sure that
the compressor mushroom “STOP” button is
pushed in and locked, and that the main power
disconnect switch is in the “OFF” position and
locked out to assure that the compressor will not
start automatically or by accident.
QUINS~ compressor fluid can be used up to 8,000
hours depending upon application and
recommendations from the compressor fluid analysis.
QUINS~ F (food grade) can be used up to 4,000
hours under good operating conditions.
QUINS~ IV can be used up to 4000 hours with
clean operating conditions. Mineral oil should be
changed after the first 500 hours of operation to make
sure the initial contaminates are removed. After that,
under good operating conditions, mineral oil can be
used up to 1,000 hours.
Draining the compressor fluid should be done while the
compressor fluid is hot to carry away more impurities.
It is strongly suggested that Quincy’s lubrication
analysis program be followed to establish compressor
fluid change internals. Compressor fluid should be
completely drained from the reservoir and compressor
fluid cooler using drain petcocks.
