PUMP INSTALLATION (FIG.8)

Not applicable for models Fekabox 110 which have the pump already fitted inside.
Ensure that the difference in level between the pump and the sewage network is compatible with the pump
performance.
Fekabox 110 l:
The Fekabox 110 is delivered with an installation kit containing respectively the parts in figure 8 for installation of both the vertical
and the horizontal outlet.
For the assembly of the kit, see figure 8
1. Adapter 2"F – 1"1/4M (not necessary for Feka VS-VX)
2. Curved hosetail, thread 2"x50 PP
3. Pipe tightening clamp in AISI304 DIN 3017
4. Short length of pipe in rubberized fabric 57x50 l=350
5. Curved hosetail 2"PP
6. Coupling for tank 2"PP

ELECTRICAL CONNECTIONS

Before connecting the system to the mains, ensure that the mains voltage is the same as the value indicated on the pump data plate.
It is recommended to apply the pump data plate (supplied in the package in addition to the one already applied on the pump by the
manufacturer) on the tank, in a clearly visible position, or on the control box.
The connection must be made as follows:
Pump:
Pass the pump cable through the cable gland supplied in the kit.
Assemble the cable gland on the tank, next to the symbol
cable gland on the inside of the

FIRST START-UP

Before starting up the electropump check that in the tank system there is no residue or other material that could
harm the correct operation of the system.
In this phase you can leave the interception valve in the inlet pipe closed and fill the lifting station with clean water. Open the
interception valve in the delivery pipe and check that the pipes are tightened and perfectly sealed and that the electropump is
working correctly. Check also that the electropump is primed. Open the interception valve in the inlet pipe and check that the station
is working correctly.
The flow of liquid coming from the various utilities must not prevent the correct operation of the floats present in the
container.
In the case of a three-phase electropump, check that the impeller is turning in the correct direction. Check also the electropump
manual. Check that the levels of float intervention are correct, and if necessary adjust them to suit the actual needs of the system.
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. Check that the electropump cannot become
unprimed during operation. Check that the number of starts per hour is compatible with the characteristics of the system
components. Check that the system is working correctly and put it into service. Close the cover or covers of the station, screwing
them into place. If necessary, fix the cover in its seat in such a way as to prevent unauthorised opening of the cover (see chapter
5.7).

8.1 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.

8.2 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.
