The IX series can be used in all countries thanks to the universal power voltage (100-240VAC).

A diaphragm rupture detection ensures user safety and a pressure overload detection protects the pump and

charge pressure than the maximum level or when the hole IC which monitors the motor rotation has failed. If the
pump is suspended (by the over-current protection) in either condition, the pump resumes operation 30 seconds
later. If the suspended operation has recurred 5 times consecutively, the pump will not resume operation any
more and will keep still. These error conditions can be released when the start/stop key is pushed once.
NOTE
The discharge pressure can rise 1.2-1.5 times higher than the maximum allowable level of the pump depend-
ing on operating conditions and piping layouts. If the pressure rises too sharp (with the closed discharge), it
may not be even detected or curbed by the over-current protection. Set up a relief valve to protect the related
devices on the discharge line from the possible pressure rise if necessary.
