Operation
Charging and Startup
For optimum performance, surge suppressors should be charged to a pressure 2 to 10 psi (0.01 to 0.07 MPa, 0.1 to 0.7 bar) lower than system pressure.

CAUTION
Automatic surge suppressors must have the air supply connected before you start pumping. Failure to do so could result in the internal air valve puncturing or rupturing the bladder.
The air pressure gauge (1) (See Parts Drawings on pages 14 and 15) on automatic surge suppressors remains at zero pressure even after the air line is connected, because the surge suppressor only allows air into the air chamber when it is required to dampen pulsation. After the air supply line is attached to the
NOTE: Automatic surge suppressors are not recom- mended for use as suction stabilizers at the pump inlet or as a surge suppressor at a
CAUTION
Manual surge suppressors must be charged before you start pumping. Failure to do so could result in the internal air valve puncturing or rupturing the bladder.
Before you start the pump, charge the surge suppres- sor with air line pressure.
1.Start the pump to generate system pressure.
2.As pressure increases to approach working pres- sure, gradually decrease the regulated air supply pressure into the surge suppressor by adjusting the regulator (4) (See Parts Drawings on pages 14 and 15).
3.Wait for up to one minute to allow the system to respond to the adjustment before you make any further adjustments. Generally, pulsation is most effectively minimized when the air supply to the surge suppressor is regulated to 2 to 10 psi (0.01 to 0.07 MPa, 0.1 to 0.7 bar) lower than system pressure.
