Restarting after power shut-off
In case of accidental stopping, make sure that the non-return valve has prevented backflow
and check that the motor cooling fan has stopped. Start the pump again following the
instructions of chapter 2.1.1 ”Starting the pump”.
2.2.
Stopping the pump
It is advisable to close the discharge shut-off / regulation valve gradually and stop the motor
immediately after. The reverse sequence is not recommended, especially with larger pumps
or longer delivery piping. That is to avoid any problems due to water hammering. If a suction
shutoff valve has been installed, it is advisable to close it completely.
