Dual-Compressor Module Maintenance

4.3Checking the Oil Level

The proper oil level varies according to the Compressor Module’s operating speed. To check the oil level on the first-stage oil separator level gauge, use the following guidelines based on operating speed.

NOTE

The oil level indicated on the first-stage oil separator sight tube varies with inlet and discharge pressures as well as operating speed. Check the oil level when the compressor is running.

4.3.1Oil Level Guidelines - Minimum Speed

When operating the Compressor Module at minimum speed—2400 rpm, 40 Hz— check the oil level in the oil level sight tube, shown at right, then refer to the following suggested maintenance actions.

If the oil level is:	Take this action:
• 1"– 3" from the bottom	No action is required.
of the oil level gauge

•Lower than 1” from the bottom Add factory-supplied PAO oil to this level (see 4.5.1 - Topping Off the Oil Level on page 20).

• Higher than 3” from the bottom Remove excess oil

(see 4.5.2 - Changing the Oil on page 21).

4.3.2Oil Level Guidelines - Maximum Speed

When operating the Compressor Module at maximum speed—4800 rpm, 80 Hz— check the oil level in the oil level sight tube, shown at right, then refer to the following suggested maintenance actions.

4.4Oil Capacity and Type

The factory oil charge of the SZO Compressor Module is 380 fluid ounces (11.25 liters).

Use the special Poly-Alpha-Olefin (PAO) blend available from the Packager. Refer to Appendix A - Material Data Safety Sheet on page 30 for details.

CAUTION

The Compressor Module REQUIRES a special PAO blend available from your Packager.

Do NOT substitute other types of oil. Using other types of oil will damage the equipment and void the warranty.
