WATSAN M15 ERU SETA plant centrifugal pump 9 Maximum water level in the sedimentation tank The water level control starts the submergible pump below the maximum water level. The water level control stops the submergible pump above the maximum water level. Minimum water level in the sedimentation tank The water level control stops the centrifugal pump and starts the submergible pump below the minimum water level. The water level control starts the centrifugal pump and stops the submergible pump above the minimum water level but the maximum water level control keeps the submergible pump working. Starting up

WATSAN M15 ERU SETA plant centrifugal pump 10 Stopping The pump includes an electronic protection function which will stop the pump in case of: lack of water over temperature overload engine frequent starts/stops (the “Alarm” light blinks) The pump automatically restarts after 30 minutes (over 24 hours) in case any kind of failure if the automatic restart function is activated.
