Sparks can ignite fumes from solvents and the fluid being pumped, dust particles, and other flammable substances, whether you are pumping indoors or outdoors, and can cause a fire or explosion and serious bodily injury and property damage. If you experience any static sparking or even a slight shock while using this equipment, stop pumping immediately. Do not use the system again until the problem has been identified and corrected. To reduce the risk of static sparking, ground the pump, surge su

CAUTION In systems using pumps with a ratio greater than 1:1, fluid may escape into the surge suppressor air line and contaminate the air supply if the diaphragm fails. Installation of a check valve in the air line will prevent fluid contamination of the air line. Flushing the System Flush the system regularly, using a compatible solvent. Do not allow fluid to dry in the pump or surge suppressor. Always flush the pump and surge suppressor before storing them for any length of time. Place the pum

. 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
