SAFETY
Security instructions to be followed by
the operator / user
Current national regulations and local safety
and hygiene requirements must be complied
with. All danger of electrocution must be
avoided (for more detailed information,
please consult the regulations drawn up by
the local electricity supplier).
Modifications to the pumping station and
use of spare parts.
No modifications to equipment and its instal-
lation may be carried out without prior con-
sultation with the ITT Lowara company. In
order to guarantee the performance of the
equipment it is essential to use original spare
parts or accessories authorised by the man-
ufacturer. Use of other spare parts may in-
validate any claims on the basis of the
guarantee or requests for compensation.
Disassembly and reassembly
During maintenance of the pumping station
(for example, draining), it is crucial to avoid
endangering persons and/or the environ-
ment.
All refuse and waste (e.g. grey cooling liquid)
must be handled in an appropriate manner in
order to avoid harm to the environment.
The lifting equipment must be constantly
kept clean and in normal working order.
All applicable regulations must be adhered to.
Because of the nature and
level of performance
required for the equipment,
noise levels may reach
70 dB.
This manual contains essential information
on installation, operation and maintenance.
These instructions must be meticulously fol-
lowed. Installation and maintenance person-
nel must read these instructions carefully
before installation and commencing opera-
tion of the pumping station. This installation
and maintenance manual must be available
at the pumping station site at all times.
Safety and warning pictograms used in
this manual.
Danger of death
This pictogram is a reminder
that any failure to respect
the safety instructions set
out in this manual may have
fatal consequences.
High voltage
This pictogram indicates that
there is a risk of electrocution.
WARNING! Failure to heed this warning
may cause damage to
equipment or affect its
operation.
Personnel qualifications
Work must be carried out exclusively by
qualified personnel.

5
DANGER (Gas, dust, fumes, smoke)
Before any work on the
equipment, authorisation
must be obtained.
Gases may form within the
pumping station and
compliance with specific
rules for installation in an
explosive environment is
imperative.
Welding, cutting by means of a blowtorch,
or grinding present real risks of fire and/or
explosion.
For these operations, carefully remove in-
flammable dust or materials present in the
work area and the surrounding space. Be
careful to ensure sufficient ventilation (risk
of explosion).
SAFETY
Safety instructions
The rules set out below must be scrupu-
lously adhered to in order to reduce accident
risks during servicing, installation and main-
tenance.
- Ensure that electrical equipment is discon
nected from the power supply and cannot
be reconnected inadvertently.
- Never work alone. During any work on the
interior of the pumping station, beware of
harmful gases and make systematic use
of a safety harness and rope as well as
breathing apparatus. Do not under-esti
mate the risks of drowning!
- Compy with local regulations for working
in confined spaces.
- Monitor the absence of toxic gases within
the work area.
- Do not under-estimate health risks.
Meticulously ensure that equipment is
clean.
- Beware of electrocution risks.
- Ensure that lifting equipment is in perfect
condition.
- Install appropriate barriers around the
work area, for example a security rail.
- Ensure that there is a safe exit route in
case of emergency.
- Wear a safety helmet, goggles and shoes.
- All persons working within sewage
facilities must be vaccinated against any
diseases which may develop there.
- A First Aid kit must be permanently
available near the facility.
- Comply with local safety instructions.
- Systematically re-close and lock the cover
before leaving the pumping station.

Checks:
Before installation or storage, check that the
Polyethylene tank and internal pipework are
in proper working order.
principle
Use both lifting handles to raise the pumping
station and place it in the pit.
Storage
Outdoor storage periods must not exceed
four months and the tank must be covered
(for example by a tarpaulin).
TRANSPORT, UNLOADING AND STORAGE
Transport:
1. Ensure the tank never comes into contact
with sharp edges.
2. Protect the tank from impacts.
Loading and unloading:
1. Carry out loading and unloading
operations with the greatest care.
2. Ensure that the pumpstation is unloaded
from the lorry by means of appropriate
lifting equipment.
3. Always use lifting slings with the correct
dimensions (reminder: maximum weight of
tank is 180 kg).

10
Filling:
Important: during filling, ensure that the tank
is vertical.
Fill material must have a granulosity of be-
tween 2 and 36 mm. Filling must be carried
out before the water table surface reaches
the top of the fill material.
1) Spread a layer of fill material 300 mm
thick (B) Compact and level the surface, then
place the Micro 10 tank on top.
2) Add a layer of fill up to a minimum height
of 700 mm.
Compact in successive layers with a maxi-
mum thickness of 50 mm.
Fill of the upper part (C) must not contain
stones more than 50 mm. in calibre.
Water table: Figure 2B
In the case of difficult surfaces (impermeable
or clayey) or of ground water, the bottom of
the pit must consist of a concrete base 0.20
metres thick.
Concrete ballasting must be poured around
the pumping station
INSTALLATION
Installation of the pumping station is always
under the entire responsibility of the firm in
charge of the installation. General informa-
tion and instructions in accordance with EN
976-2:1997
Warning:
Never install pumps before covering the tank
with earth.
Installation in the ground
The pumpstation is designed to resist
stresses linked to the presence of a water
table flush with ground level.
The pumping station must not be installed in
soil composed of peat. When the pumpsta-
tion is installed in soil which is argillaceous
(clayey) , granular, or silty, a geotextile fabric
must be laid over all excavation surfaces.
The geotextile fabric prevents the fill material
from becoming mixed with the soil (A).
Excavation dimensions:
1) Depth: 300 mm greater than the level in-
tended for installation.
2) Width: two metres greater than the pump-
station.

INSTALLATION
Connection of inlet pipe (fig 2)
• Fix the self-adhesive drill former on the drill
area (flat piece shown)
• Drill the tank with a jigsaw or similar
• Fit gasket Ø160
• Chamfer exterior of tube Ø160
• Pass the tube through the gasket
Connection of discharge pipe
Connect the pump discharge pipe to the net-
work pipe with the PVC threaded/smooth fix-it
coupling (fig. 3)
Use of a flexible pipe fitting between the pump-
station and the network pipe is recommended in
order to avoid stresses or breakage of piping
due to any ground compaction.
Passing cabling through (fig. 4)
In the upper part of the flat delivery input drilling
area is the assembly location for the two pump
glands.
Pass the cables through these pump glands.
Ensure that sufficient length of cable is left for
any subsequent work on the pump.
Note:
Separate the earth cable from the live cable on
the pump.
Above the hooks for the regulators, in the flat
area, is the assembly area for the pump glands
for the level regulators.
Pass the cables through the pump glands.
Ensure that sufficient length of cable is avail-
able. Adjust the length and hook the cables
over their hook.
Hooks for supporting chains (pumps) (fig. 5)
The hooks are located on the stainless steel
cross-beam.
There are 2 small folded lugs on the cross
beam which enable the chains to be hookedup
(fig. 5).
