unauthorised opening of the cover (see chapter 5.7).

9.1 Operating flow rate

It must be guaranteed that the speed of the liquid in the delivery pipe is at least 0.7 m/s and lower than 2.3
m/s.

9.2 Operation

When the liquid in the tank reaches the level corresponding to the closure of the float contact that commands
the electropump, the pump starts and gradually empties the container. The electropump stops when the
liquid reaches the minimum level corresponding to the opening of the float contact. When there are two
electropumps, the floats must be adjusted so that the second pump starts after the first and only if the first is
not able to send to the sewer duct as much liquid as arrives from the various utilities. There may be a float
placed higher than the others in the pumping station, its function is to indicated the presence of an
abnormally high level of the liquid in the tank.

10. MAINTENANCE

After starting up the plant, it is advisable to inspect and clean it, especially the no return valve, about every
three months. This interval may be increased after the first inspections have given a favourable outcome.
Clean the pump accurately, removing any foreign bodies stuck in the intake grille and check that the float
moves freely. If necessary, remove the pump from the tank.
It is recommended to clean the system at least once a year with running water, operating the pump
repeatedly.
