Instruction Manual QGV 2

Section V - Servicing

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:

• Wait for the unit to cool before starting service. Temperatures may exceed 180°F when the compressor is operating.

• Clean up fluid spills immediately to prevent slipping.

• Loosen, but do not remove, flange or component bolts. Carefully pry apart to be sure there is no residual pressure before removing bolts.

• 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.

NOTICE!

Maintenance or service should be performed by trained and qualified service technicians only.

CAUTION!

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

Water Removal

Water vapor may condense in the reservoir and must be removed. Water is heavier than the compressor fluid and will collect at the bottom of the reservoir.

The frequency with which the 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.

WARNING!

Water content in the compressor fluid in excess of 200 PPM could cause bearing damage and/or airend failure.

To drain water from the reservoir:

• Turn the compressor off by the main switch and perform proper lockout/ tagout procedure.

• Completely depressurize the compressor circuits (reference

‘Preparing for Maintenance or Service’ on page 70 and ‘Safety’ instructions on page 72).

• Allow compressor to sit idle for at least

5 minutes.

• Open the drain valve.

• Close the valve when the water flow changes to compressor fluid.

(When the drain is first opened some compressor fluid may come out before the water starts to flow.)

• Since this water will contain some compressor fluid, dispose of the water in accordance with Local, State, and

Federal environmental regulations.
