Quincy Compressor 244

Drain liquid from the air receiver and moisture trap

Turn on cooling water (watercooled units)

Jog the starter button and check compressor rotation

Start compressor per factory instructions

Ensure the compressor is disconnected from the power supply

Verify that all safety precautions from SECTION 5, Stopping For Maintenance, are followed

Remove the pressure switch cover

Record the current air pressure reading

Adjust the spring loaded adjustment screw

Record the new air pressure reading

Ensure the compressor is installed in a clean, well-lighted, and adequately ventilated area.

Ensure sufficient space is provided around the compressor for safe inspection, cleaning, and maintenance.

Record the oil level on the bayonet gauge.

Is the oil level between the high and low marks?

Is the oil discolored or contaminated?

Drain and replace oil if contaminated.

Measure the span length of the drive (in inches)

Calculate the required deflection (in inches)

Lay a straightedge across the top outer surface of the drive belt from pulley to sheave

Apply pressure with a belt tension gauge and record the deflection force reading

Is the deflection force reading within the minimum and maximum values?

Adjust the belt(s) if necessary

Measure the span length of the drive

Calculate the required deflection in inches by multiplying the span length by 1/64 (.016)

Lay a straightedge across the top outer surface of the drive belt from pulley to sheave

Apply pressure with a belt tension gauge at the center of the span to the predetermined deflection

Record the reading on the belt tension gauge

Is the deflection force reading within the minimum and maximum values?
