Safety

Safety procedures while servicing the compressor are important to both the service personnel and to those who may be around the compressor and the system it serves. Listed below are some, but not all, procedures that should be followed:

•Always check power supply disconnect. The Power- on light may be inoperable.

•Wait for the unit to cool before starting service. Temperatures may exceed at 350°F when the compressor is working.

•Clean up fluid spills immediately to prevent slipping.

•Loosen, but do not remove, flange or component bolting. Then, carefully pry apart same 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.

!CAUTION

Unusual noise or vibration indicates a problem. Do not operate the compressor until the source has been identified and corrected.

Fluid Specifications

Each QSD™ unit comes equipped with a fluid level sight gauge, fluid fill opening, and a fluid drain located on the gearbox.

QSD™ compressors are factory filled with Quinsyn GL or Quinsyn GLF (food grade) synthetic fluid. The use of other brands or types of fluid may reduce the design life of the compressor or cause problems with filtration or bearing performance. Consult Quincy Compressor before changing brands or types of fluid.

Quinsyn GL or GLF synthetic fluid is available from any authorized Quincy Distributor and is recommended for use in all Quincy QSD™ oil-free compressors. Failure to follow this recommendation will adversely affect your warranty.

!CAUTION

Do not mix different grades or types of fluid. Do not use inferior grades of fluids. Failure to follow these recommendations may cause severe fluid breakdown, resulting in the information of varnish and sludge throughout the system. This will result in clogging of the cooler and internal fluid passages. Warranty will be voided.
