8.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).

9.After adding the same amount of oil that was drained from the Compressor Module, start the Compressors and verify that the operating oil level is correct (see 4.3 - Checking the Oil Level on page 2). If necessary, adjust the oil level (see 4.5.1 - Topping the Oil Level on page 20).

10.Turn the knob on the backseating control valve counterclockwise to close the Schrader valve.

11.Replace the protective cap on the Schrader valve.

12.Return the Compressor Package to service.

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