To maintain warranty and to insure the compressor operates correctly and safely you must use gen-
uine Quincy Compressor parts. Failure to correctly install equipment, use of non-genuine Quincy
Compressor parts, or perform recommended scheduled maintenance, will void warranty and result
in damage to or failure of the equipment. This could also result in a fire and fatalities.
Before performing any maintenance, stop the compressor, close the shut-off valve at the package
discharge, remove all electrical power from the equipment per OSHA requirements for lock-out
and tag-out, and verify the receiver tank on the package is at zero pressure. You can now safely
work on the package.
If the branch circuit protection is provided using a fused disconnect to supply power to the com-
pressor package then verify that all the fuses are of the same type and properly sized. If a circuit
breaker is used to supply power then verify that it is properly sized. Visually inspect and verify
that the connections at the branch circuit protection device are tight and the wire insulation is
not degraded. Visually inspect the wire from the branch circuit protection device to the compres -
sor starter to verify that it is sized correctly and in good order. Verify the power wire and ground
connections at the compressor starter are tight and in good order. Also verify the wire connections
from the compressor starter to the compressor motor are tight and in good order. Document and
correct any issues found.
Inspect all tubing in the compressor package for possible leaks, or normal aging and replace with
genuine Quincy Compressor parts as needed. Verify all tube fittings are tight and tubes are securely
held in the fittings. Also check all nylon tubes for chaffing, cracks, and flexibility. Replace with
genuine Quincy Compressor parts to insure safe operation.
Drain any condensation that may have collected in the receiver tank. Take oil sample for evalua -
tion and be sure to mark sample with customer name, compressor model, compressor serial num-
ber, and running hours on the compressor. Replace oil with genuine Quincy Compressor oil of the
same type when needed. Low oil will result in oil foaming, oil carryover, and higher compressor
temperatures that could result in a fire.
Replace all consumables at recommended service intervals or sooner if operating conditions war-
rant.
Normal service intervals
Air Filter 2000 Hours
Oil/Fluid Filter 1000 Hours
Separator 4000 Hours
Oil/Fluid 8000 Hours * Based on fluid type and sample testing this time can be different.
Or replace all consumables every 12 months.
Poor maintenance or the use of non-genuine Quincy Compressor parts will cause equipment failure
and possibly result in fire.
