Page 10 Installation Fluid Pressure Relief Kit CAUTION Pressure Relief Kit 235409 (V) is available for Aluminum Pumps, to prevent overpressurization and rupture of the pump or hose. See Fig. 7. The kit includes instructions. Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm area (for example, from an underground tank).
Page 11: Operation
Operation Pressure Relief Procedure 5. Close the fluid drain valve (J). WARNING 6. Back out the air regulator (C) knob, and open all bleed-type master air valves (B, E). PRESSURIZED EQUIPMENT HAZARD The equipment stays pressurized until pressure is 7. If the fluid hose has a dispensing device, hold it manually relieved.
