Ensure that the switch from shut down to start-up
occurs only and exclusively if the floats find themselves in the position shown in Fig 11A, 11B, 11C, 11D.
Ensure that the switch from start-up to shut down
occurs only and exclusively if the floats find themselves in the position shown in
Fig 12A, 12B, 12C, 12D.
The electric connection of the floats must be carried out in such a way that ensures the shutdown of the pump in cases of a malfunctioning float.
Make sure that effective volume of the tank does not become so low that the number of starts per hour exceeds the maximum
admitted.
