___ 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).
