17. When using pump with pressurized systems, make sure the pressure of the system does not exceed the
maximum pressure rating on the pump nameplate. Be sure to de-pressurize system prior to hook up or
disconnecting the metering pump.
18. Electronic power modules are equipped with automatic reset thermal overload devices and may reset
unexpectedly.
19. The pump is designed to operate using a backpressure/injection valve. If the discharge point is below the liquid
level of the source or if the discharge pressure is less than the suction pressure, siphoning may occur. To
correct this condition, install an anti-siphon valve or other anti-siphon device. Check local regulations which may
apply. (Ref. Figure G1).
20. If the power cord is unplugged or in the event of electrical power interruption while the pump is operating, the
pump will remember its last operating state for years and will resume operation as before, whenever power is
restored.
