3 START-UP

• Pump discharge air supply pressure should be regulated between 20 psig

(.14 MPa) minimum and 80-psig (.55 MPa) maximum.

• Pump Vacuum Air Supply should be regulated at 80 psig (.55 MPa). (Note:

Not required for booster pump installations.)

• Open the fluid suction (IN) line valve, if necessary.
• Open the fluid discharge (OUT) line valve, if necessary.
• Start with pump air supply regulator at low (≈ 20 psi) pressure setting.
• Tune Optics per Section 3.1.i
• Table 33: Consumption / Efficiency in Section 3.2 can be used to determine

approximate air consumption. Air consumption in booster pump applications
will be much less, see Section 3.3.

• Refer to Troubleshooting, Section 5, if pump fails to start.

NOTE: When operating pump as a booster pump, vacuum air supply may be
turned off, conserving air.

CAUTION: When handling potentially dangerous fluids under pressure,

the pump and its fittings should be placed in an enclosure. NOTE: When
operating pump as a booster pump, vacuum air supply may be turned off,
conserving air.
