Minimum and Maximum Operating Temperatures Find the minimum and maximum operating temperatures for your surge suppressor unit in the list below. These temperature limits are stated at zero gauge pressure.

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. Automatic Models 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 one-way check valve (8) and air is available, you can start the pump. No further adjustments are necessary. NOTE: Automatic surge suppressors are not recommended for use as suction stabilizers at the pump inlet or as a surge suppressor at a quick-closing valve. Adjustable surge suppressors should be used for such applications. Manual Models 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 suppressor with air line pressure. 1. Start the pump to generate system pressure. 2. As pressure increases to approach working pressure, 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. . . Troubleshooting WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 7. R...
