CHECK FOR THESE CONDITIONS UNDER NORMAL OPERATION:

___ 1. Compressor speed should range from 2400 to 4800 rpm during normal operation.

___ 2. Suction pressure should range from 0.75 psig to 25 psig.

___ 3. Discharge pressure should range from 70 psig to 190 psig, depending on the model (see Compressor Module Nomenclature on page iv).

___ 4. Pressure differential between suction and discharge is at least 70 psi.

___ 5. First-stage separator temperature should be between 170°F and 220°F (77-104°C).

___ 6. Oil cooler fans should either run continuously or cycle periodically under normal conditions.

If any of these conditions are not met during normal operation, shut down the unit and refer to 5.0 - Troubleshooting on page 25.
