It is indispensable to have the electric and hydraulic connections made by skilled personnel, in
possession of the technical qualifications indicated by the safety standards concerning the
design, installation and maintenance of technical plants, in force in the country where the
product is to be installed.
Failure to comply with the safety regulations not only causes risk to personal safety and
damage to the equipment, but invalidates every right to assistance under guarantee.

1.2

The term skilled personnel means persons whose training, experience and instruction, as
well as their knowledge of the respective standards and requirements for accident prevention
and working conditions, have been approved by the person in charge of plant safety,
authorizing them to perform all the necessary activities, during which they are able to

5. TANK INSTALLATION

The lifting stations of the Fekabox – Fekafos series have various inlet and outlet possibilities for the pipes.
Depending on the type of installation and on the local standards in force it may be necessary to provide a
siphon, a non-return valve on the pipe connecting to the public/private sewer network or to other ducts.
Always refer to the local and/or national regulations, laws and standards in force. Anyway it is recommended
to install check valves and interception valves upstream and downstream from the station. An example of
installation is shown in chapter 4.

All the ducts must be installed in such a way that they are not stressed. The ducts must not
exert stress on the station. Check that the electropump is securely fixed to the pipes and that

all the hydraulic connections are tightened and watertight.
Where necessary provide suitable means for avoiding the transmission of vibrations and for protecting the
pipes against the formation of ice.

5.1 Placing the tank inside the building

The tank may be laid on the floor, under the ground or housed in a masonry pit. Fig.2, Fig.3

In any case the surface on which it is laid must be perfectly horizontal and it must be ensured that
the whole bottom of the tank is in contact with the surface.

For Fekabox 200 l, Fekabox 280 and Fekabox 550 Double l the cover of the tank is trafficable

(max. weight 100 Kg, see fig. 1).

In indoor installations (garage, basement, technical room), the tank must be fixed to the

ground using the slots provided to prevent rotations, as indicated in figure 4.

Leave a free space of at least 60 cm around and above the station for installation and

maintenance.

5.2 Placing the tank outside the building

If the tank would not buried, to prevent damage to itself and to the seals, you should not expose it to heat
sources such as direct sunlight can be at certain times of the year.

Do not position the lifting station directly on the ground. The site chosen must not have ground

water and must not be subject to flooding. Suitable anchor the station so as to avoid rotation

and floating. For this you can use the slots on the base of the tank.

There must be a horizontal base suitable to bear the weight of the station during its operation.

Depending on the characteristics of the terrain it may be necessary to create walls with bricks,

prefabricated components or concrete. Fill the space between the ditch and the station with

sand and compact it suitably. Protect the station suitably against frost.

Fig. 4

FIX THE TANK TO THE GROUND
BEFORE USE

Use screws TE M8 with respective
fixture, use specific washers for soft
materials ISO 7093

ENGLISH

42

Do not drive vehicles over the cover (see fig. 3). Fekabox / Fekafos: the cover can bear

passing loads of 100 kg if installed underground.

You can close the ditch with a cover (manhole) or other means for facilitating subsequent maintenance. Put
up suitable signals indicating the presence of the station so as to avoid possible damage caused
unintentionally. Ensure that there is sufficient space for installation and maintenance around and above the
lifting station.

Position any capacitor holder and/or electric control panel in a place sheltered from the

elements.

After having completed the hydraulic and electric connection, it is recommended to place clean sand around
the container to reduce any movements caused by the system and/or by the surrounding terrain.

5.3 Making holes for the collection and ventilation pipes

Choose the inlet duct already prepared for the inlet pipe so that the arrival of the liquid does not disturb the
operation of the floats (of both the pump and the tank, if provided).
The Fekabox-Fekafos tanks have multiple inlets, all marked with the symbol:

Make a hole in the tank in the determined areas, indicated by the symbols shown above.
To make the hole use a hollow cutter as shown in figure 5 (indicative figure) with the correct diameter to suit
the diameter of the input pipe.

5.4 Gluing the collection and ventilation pipes

Before gluing the PVC pipe must be deburred and cleaned with a suitable solvent on the whole surface
where the glue will be applied.
To ensure that it sticks firmly, the glue must be applied on the whole newly deburred surface, at least for a
complete round.

Attention: Use glue suitable for sticking PVC materials with PE (for example: Simson ISR 70-03)

Also check the drying times indicated in the specific instructions for the glue used.
For the discharge pipe 2”PP (Fekabox 200) use the multifibre nylon sealant Loctite 55, the polymerising GEI
sealant Loctite 5331 or Teflon. For the steel pipe znb 2” (Fekabox 200, Fekafos 280, Fekafos 280 Double,
Fekafos 550 Double) and the other inlet connections use the most suitable glue in accordance with the
standards of the local market.

5.5 Connecting the delivery pipe to the sewer network

Fekabox 200, Fekafos 280 and Fekafos 550 tanks have a 2” GAS outlet connection.
To guarantee a perfect seal it is recommended to use Teflon or suitable glues depending on whether the
material being glued is plastic (PP or PVC) or metal.

5.6 Connecting the ventilation pipe

Remember to provide a ventilation pipe to avoid the formation of inflammable, explosive or toxic mixtures.

On the station identify the seat for the ventilation duct, marked with the symbol

. Open the duct as
indicated in point 5.3 and connect the ventilation pipe so that it can evacuate any condensate from the
station. Check that the coupling is watertight.
The various national regulations may require different ratios between the diameter of the outlet pipe and
that of the ventilation pipe. Ensure that the pipe outlet is in the open (for example, above the ridge of the
roof if the station is installed inside a building) and that the exhaust gases cannot get into other places such
as buildings, rooms and similar. Avoid horizontal stretches in the ventilation duct.

5.7 Closing the cover

Check that the gasket of the cover is lying in the bottom of its seat and is not twisted before screwing the
cover onto the tank. The tank is shipped with the gasket already fitted under the cover.
Check that the gasket does not slip in the thread during screwing. In case of installation inside buildings, the
cover must be screwed right down until the threaded seat appears in the slot shown in the figure, to
guarantee that the station is hermetically sealed against liquids and gas.
Before tightening the cover of the tank, lubricate the thread and O-ring using soapy liquids or lubricants for
plastic pipes/couplings.

To prevent unauthorised opening of the cover, it is recommended to fix it to the station with

the screw and the metal bracket provided. (see fig. 6B).

The screw must be passed through the slot on the outer edge of the cover, and screwed into the seat in the tank.
There are two cylindrical seats on the cover which can be used to facilitate closing of the cover by levering
with suitable tools (see fig. 6A).

5.8 Provision for emergency drainage

On the rear, at the base of the station, is a connection for an emergency drainage system, marked by the

symbol

. You can use the connection to attach a secondary pump (for example a manual diaphragm
pump), the discharge pipe of which must be independent from that of the internal electropump in the station.
Identify the seat for the duct on the bottom of the station, open the duct and connect the emergency drainage
pipe. Check that the coupling is watertight.

5.9 Non-return valve

Install a non-return valve in the pipe connecting to the public/private sewer network. This will avoid the reflux
of liquid. Place the valve at a distance of at least 1 metre from the lifting station to allow the flow of liquid,
moved by the pump, to open the shutter of the valve (unless indicated otherwise by the manufacturer).
Always refer to the local and/or national regulations, laws and standards in force.
The non-return valves are available as accessory kits.

5.10 Interception gate valve

Install an interception valve in both the inlet pipe and the delivery pipe (connection to the public/private sewer
network). In this way maintenance work can be carried out without having to drain the whole system. Gate
valves or ball valves may be used.
The interception valves are available as accessory kits.

See example of installation in chapter 4.

7. ELECTRICAL CONNECTIONS AND ADJUSTMENT OF FLOATS

7.1 Choice of the electric control panel

Below are the indications for the choice of a control panel only for Fekafos 280 and 280 Double and Fekafos
550 Double models because for Fekabox models the pump is automatic.
The station must be adequately protected against overload and short-circuit.

Check the correct combination of electrical data between the control panel and the electropump.
An improper combination can cause problems and not guarantee the protection of the electric
motor.

Always refer to the electropump manual and to the instructions supplied with the electric panel.

The electrical connection must be made in accordance with the local safety regulations in force,
and exclusively by qualified personnel.

Commissioning

Before commissioning, read this instructions manual, that of the electropump and that of the
electric panel. Keep the manuals with care.

The commissioning operations must be performed exclusively by expert and qualified personnel,
in compliance with the regulations in force.

Always refer to the local and/or national regulations, laws and standards in force.
It is recommended to contact the Dab Assistance Service for the commissioning of the system.

For connecting the system it is recommended to use exclusively the panels ED, E-BOX indicated by the
manufacturer, supplied complete with detailed instructions for electrical connection and use.

7.2 Electrical connections

The pumps are provided with an earthed cable; ensure that the earth system is efficient. Before connecting the
system to the mains, ensure that the mains voltage is the same as the value indicated on the pump data plate and
that the earth connection can be made efficiently.
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 fitted on the tank, recognisable by the symbol

, tighten
the ring nut and connect the cable to the panel as indicated in the respective manual.
For Dab pumps and for any pump fitted with a cable having a section of 4G1.5 mm2 or larger, to ensure that the
passage and seal are guaranteed by the cable clamps, it is advisable to replace the grommet already fitted in the
clamps with the grommet supplied in the tank kit. For references to the details, figure 10 shows an example of the
replacement of the grommet on the Fekafos 280 tank.

Every single cable of the floats is composed of three leads: BLACK-BROWN-BLUE. The BLUE lead is
not used and must be insulated by the user.

8. PREPARATION OF THE ALARM SYSTEM FOR FEKAFOS 280 AND 280 DOUBLE (SUPPLIED
ONLY ON REQUEST FOR FEKABOX 200)

The preparation consists of having a float support composed of a PP
pipe, fig. 11. For Fekabox 200 the length must be shortened to 184 mm.

Strictly respect the lengths shown in the figure.
Pass the float cable out of the tank, through the preassembled grommet

, tighten the ring nut and connect it to the control unit. For
Fekabox 200, in the kit supplied, along with the alarm floating support
there will be an extra cable clamp, necessary for the float cable to come
out.

Before filling the tank, activate the float manually to check the operation
of the alarm system.

Make a test of the complete system with clean water, checking that the
alarm system intervenes only in the case of a pump malfunction or lack of
power in the mains.
To do this, proceed as follows:

1. Fill the tank up to pump intervention level and interrupt the power supply to the pump. In this situation the

alarm system must not intervene.

2. Continue filling the tank until the alarm system intervenes. Check that in this condition the water level is a

few centimetres below the MAX emergency level 510 mm for Fekabox 200 and 680 mm for Fekafos 280

– 280 D.
If this condition does not occur, shorten the length of the cable between the cable grommet and the safety float.
The maximum level alarm float system can be managed by panels of the ED, E2D, E-BOX family and by the
Control AS1. The latter is an electronic control unit with charge reserve already equipped with a float.

9. 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).

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.
