. 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 z
