Compressor Oil Charge

Caution: This procedure is to be done by APC-trained personnel only.

You may need to add oil to air-cooled equipment, depending on the condenser size and the lengths of tube running between the equipment and the condenser.

Caution: Do not charge the compressor with too much oil, or compressor damage could result. The only way to drain oil from the compressor is to remove the compressor from the equipment, which cannot be done when the equipment is in the row.

Oil charging procedure

1.Calculate the approximate amount of additional oil needed using the following formula:

0.7x {(R x 0.022 x 16) – (C x 0.10)} = A

R — Refrigerant in the system (this amount should have been recorded during installation)

C — Compressor oil charge (in fluid ounces)

A — Amount of additional oil (in fluid ounces).

Note: The compressor used in this equipment comes with an internal oil charge of 1064 ml (36 fl oz).

In the following example, there are 20 pounds of refrigerant in the system.

(20 x 0.022 x 16)–(36x 0.10)

0.7{(20 X 0.022 X 16) - ( 36 x 0.1)} = 2.3 fluid ounces of additional oil.
