Damage prevention in case of failure
Like any other electrical device, this product may fail due to a
lack of mains voltage or a technical defect.
If damage (including consequential damage) can occur as a re-
sult of product failure, the following precautions can be taken
at your discretion:
Installation of a water level dependent (under circumstances,
mains-independent) alarm system, so that the alarm can be
heard before damage occurs.
Inspection of the collecting tank/chamber for tightness up to
the top edge before – or at the latest, during – installation or
operation of the product.
Installation of backflow protection for drainage units that can
be damaged by wastewater leakage upon product failure.
Installation of a further product that can compensate in case
of failure of the other product (e.g. duplex unit).
Installation of an emergency power generator.
As these precautions serve to prevent or minimise consequen-
tial damage upon product failure, they are to be strictly obser-
ved as the manufacturer' s guideline – in line with the standard
DIN EN specifications as state of the art – when using the pro-
duct.

SAFETY INSTRUCTIONS

This instruction manual contains essential information that
must be observed during installation, operation and servic-
ing. It is therefore important that the installer and the respon-
sible 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.
In this instruction manual, safety information is distinctly la-
belled with particular symbols. Disregarding this information
can be dangerous.

Qualification and training of personnel
All personnel involved with the operation, servicing, inspection
and installation of the equipment 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 responsi-
bility of the personnel must be precisely regulated by the ope-

Safety-conscious working
The safety instructions in this instruction manual, 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 energy must be pre-
vented.
Leakages of dangerous (e.g. explosive, toxic, hot) substances
must be discharged such that no danger to people or the envi-
ronment occurs. Legal regulations must be observed.
Safety instructions for installation, inspection and mainte-
nance works
As a basic principle, works may only be carried out to the equip-
ment when it is shut down. Pumps or plant that convey harmful
substances must be decontaminated.
All safety and protection components must be re-fitted and/or
made operational immediately after the works have been com-
pleted. Their effectiveness 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 altered in agreement
with the manufacturer. The use of original spare parts and
accessories approved by the manufacturer is important for
safety reasons. The use of other parts can result in liability for
consequential damage being rescinded.
Unauthorised operating methods
The operational safety of the supplied equipment is only guar-
anteed if the equipment is used for its intended purpose. The
limiting values given in the "Technical Data" section may not be
exceeded under any circumstances.
Instructions regarding accident prevention
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, safety 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 regulations and make
sure that a first-aid kit is to hand.
In some cases, the pump and the pumping medium may be hot
and could cause burns.
For installations in areas subject to explosion hazards, special
regulations apply!
