Safety instructions

This instruction manual contains essential in-
formation that must be observed during instal-
lation, operation and servicing. It is therefore
important that the installer and the responsi-
ble technician/operator read this instruction
manual before the equipment is installed and
put into operation. The manual must always be
available at the location where the pump or the
plant is installed.
Failure to observe the safety instructions can
lead to the loss of all indemnity.
Labelling of instructions
In this instruction manual, safety information is
distinctly labelled with particular symbols. Dis-
regarding this information can be dangerous.
General danger to people
Warning of electrical voltage
ATTENTION! Danger to equipment and opera-
tion
Qualification and training of personnel
All personnel involved with the operation, serv-
icing, inspection and installation of the equip-
ment must be suitably qualified for this work
and must have studied the instruction manual
in depth to ensure that they are sufficiently
conversant with its contents. The supervision,
competence and areas of responsibility of
the personnel must be precisely regulated by
the operator. If the personnel do not have the
necessary skills, they must be instructed and
trained accordingly.
Safety-conscious working
The safety instructions in this instruction man-
ual, the existing national regulations regarding
accident prevention, and any internal working,
operating and safety regulations must be ad-
hered to.
Safety instructions for the operator/user
All legal regulations, local directives and safety
regulations must be adhered to.
The possibility of danger due to electrical en-
ergy must be prevented.
Leakages of dangerous (e.g. explosive, toxic,
hot) substances must be discharged such that
no danger to people or the environment oc-
curs. Legal regulations must be observed.
Safety instructions for installation, inspec-
tion and maintenance works
As a basic principle, works may only be carried
out to the equipment when it is shut down.
Pumps or plant that convey harmful substanc-
es must be decontaminated.
All safety and protection components must be
re-fitted and/or made operational immediately
after the works have been completed. Their ef-
fectiveness must be checked before restarting,
taking into account the current regulations and
stipulations.
Unauthorised modifications, manufacture
of spare parts
The equipment may only be modified or al-
tered in agreement with the manufacturer. The
use of original spare parts and accessories ap-
proved by the manufacturer is important for
safety reasons. The use of other parts can result
in liability for consequential damage being re-
scinded.
Unauthorised operating methods
The operational safety of the supplied equip-
ment is only guaranteed if the equipment is
used for its intended purpose. The limiting val-
ues given in the "Technical Data" section may
not be exceeded under any circumstances.
Instructions regarding accident preven-
tion
Before commencing servicing or maintenance
works, cordon off the working area and check
that the lifting gear is in perfect condition.
Never work alone. Always wear a hard hat, safe-
ty glasses and safety shoes and, if necessary, a
suitable safety belt.
Before carrying out welding works or using
electrical devices, check to ensure there is no
danger of explosion.
People working in wastewater systems must
be vaccinated against the pathogens that may
be found there. For the sake of your health, be
sure to pay meticulous attention to cleanliness
wherever you are working.
Make sure that there are no toxic gases in the
working area.
Observe the health and safety at work regu-
lations and make sure that a first-aid kit is to
hand.
In some cases, the pump and the pumping me-
dium may be hot and could cause burns.
For installations in areas subject to explosion
hazards, special regulations apply!

Areas of application

Submersible pumps in the MultiFree range are
suitable for pumping wastewater in municipal
and industrial pumping stations, and in rain-
water retention tanks. The smallest models also
perform well in disaster control applications.
MultiFree pumps are favoured for use with:
ū wastewater containing fibres that form
bundles
ū wastewater containing solids (without
stones)
ū abrasive wastewater
ū wastewater containing gas or air pockets
ū mixed wastewater
ū untreated water
ū raw sludge
ū surface water and rainwater
The submersible pumps are supplied as UAK
(without explosion protection) or as UFK (with
explosion protection).
When using the pumps, the relevant national
laws, regulations and stipulations must be
adhered to, for example:
• Installation of low-voltage systems
(e.g., VDE 0100 in Germany)
• Safety and working materials
(e.g., BetrSichV and BGR 500 in Germany)
• Safety in wastewater systems
(e.g., GUV-V C5, GUV-R 104 and GUV-R 126
in Germany)
• Electrical systems and operating resources
(e.g., GUV-V A2 in Germany)
• Explosion protection
EN 60079-0:2006, EN 60079-1:2007,
EN 60079-14:2009, EN 60079-17:2008 and
EN 1127-1:2008
For non-standard utilisation conditions in areas
subject to explosion hazards, please ask the lo-
cal authority responsible.
In Germany, this would be, for example, the
Trade Supervisory Centre (Gewerbeaufsicht),
the Technical Inspection Agency (TÜV), the
building authority (Bauamt) or professional or-
ganisation (Berufsgenossenschaft).
The installation and operation of this equip-
ment is regulated by the ordinance concerning
the protection of health and safety in the pro-
vision of work equipment and its use at work,
concerning safety when operating installations
subject to monitoring, and concerning the
organisation of industrial health and safety at
work, (Betriebssicherheitsverordnung), Article 1.
Modes of operation
with the pumped medium at a temperature
of 40°C:
Motor submersed: continuous operation S1
Motor emerged: short duration operation S2;
see "Technical Data"
Motor emerged: intermittent operation S3;
see "Technical Data"
The submersible pump is frost-resistant down
to -20°C when stored in dry conditions. When
