Safety
NOTE:
Only trained and qualified technicians should perform
maintenance.
Safety procedures performed while servicing the vacuum
pump are important to both the service personnel at the
time of servicing and to those who may be around the
vacuum pump and the system it serves. Listed below are
some, but not all, procedures that should be followed:
•
Wait for the unit to cool before starting service.
Temperatures at 120°F can burn the skin, some surfaces
may exceed 200°F when the vacuum pump is working.
•
Clean up fluid spills immediately to prevent slipping.
•
Loosen, but do not remove, flange or component
bolting, then carefully pry apart to be sure there is no
residual pressure or vacuum before removing bolting.
•
Never use a flammable solvent such as gasoline or
kerosene for cleaning air filters or vacuum pump parts.
•
Safety solvents are available and should be used in
accordance with their instructions.
•
Improper assembly will result in damage to the vacuum
pump 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 vacuum pump until the source
has been identified and corrected.
Lubrication
Each unit comes equipped with a fluid level gauge, a fluid
fill opening located on the side of the air/fluid reservoir
and a fluid drain located on the bottom of the reservoir.
Each unit is factory filled with QuinSyn
® synthetic fluid or
QuinSyn ® F (food grade) synthetic fluid.
! DANGER !
Hot fluid under pressure could cause death or
serious injury. Do not remove the fluid fill plug
and attempt to add fluid to the air/fluid reservoir
while the vacuum pump is in operation. Be sure
that the vacuum pump’s red 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 vacuum pump will
not start automatically or by accident.
QUINSYN ® fluid can be used between 1,000 and 8,000
hours depending upon the application. If the application
has gases or vapors other than dry air, consult the factory
before operation. QUINSYN F
® food grade can be used
between 2,000 and 4,000 hours under good operating
conditions.
Draining of the fluid should be done while the fluid is hot
to carry away more impurities. It is strongly suggested
that Quincy's lubrication analysis be followed to establish
fluid change intervals. Fluid should be completely drained
from the reservoir and fluid cooler using drain petcocks.
Fluid Specifications
We recommend that all Quincy rotary screw vacuum
pumps be filled with QuinSyn
® synthetic fluid. QuinSyn ®
is available from any authorized Quincy distributor. For
applications requiring a food grade fluid, we recommend
QuinSyn F
® . Failure to follow the above could void your
warranty.
Fluid Life
A free service provided with the use of QuinSyn ®
products is a fluid analysis. This analysis provides you
with important information regarding the performance of
the fluid and in detecting any special problems that might
arise. Fluid samples should be taken at the time of fluid
filter changes, at 1,000 hour intervals or as indicated on
the analysis report. Fluid sample bottles, labels and
instructions are provided with the vacuum pump package
at the time of shipment. Additional sample bottles may be
purchased through your distributor.
