4.5Adding and Removing Oil

Oil is drained from the system through the Schrader valves on the Compressor suction fittings, first-stage oil separator and oil cooler (see Figure 15 on page 21).

4.5.1Topping Off the Oil Level

See 4.4 - Oil Capacity and Type on page 19 before adding oil. Also refer to 4.2 - Maintenance Tools on page 18 for information about the tools used in this procedure.

Note

Adding oil through the Schrader valve on either compressor suction fitting permits adding the oil with the compressor running.

Adding Oil

1. Turn the knob on the backseating control valve fully

RIGHT SIDE VIEW

counterclockwise.

 

2.Remove the protective cap from the Schrader valve on either compressor suction fitting and connect the backseating control valve.

3.Connect one end of the oil transfer hose to the back- seating control valve.

4.Connect the opposite end of the hose to the oil transfer pump.

5.Pour PAO oil into a clean container and attach the extension hose to the threaded neck of the container.

6.Turn the knob on the backseating control valve clockwise to open the Schrader valve and slowly open the oil transfer hose ball valve.

Caution

When pressure is applied to the oil pump, the handle may extend rapidly.

7.Move the pump handle slowly using long, slow, full strokes on the pump handle to transfer oil into the Compressor until the desired oil level is reached. One full pump stroke dispenses 1.6 oz. (47ml) of oil (see 4.3 - Checking the Oil Level on page 19).

8.Turn the knob on the backseating control valve counterclockwise to close the Schrader valve and remove the control valve.

9.Replace the protective cap on the Schrader valve.

10.Return the Compressor Package to service.

11.Check for leaks at all fittings that have been disturbed.
