Allowing the pump to run dry will damage the unit!
Protection against Running Dry
Check the pump is always fully filled with water. Running the pump dry
can destroy the mechanical seals and plastic parts within seconds.
Never let the pump run dry not even when checking for the direction
of rotation.
Ventilate the pump and the suction line before starting up.
