Please note that certain devices require a relay to function prop-
erly, e.g. PTC thermistor and PT100 sensor. This relay can be
obtained from the manufacturer or an electrical supply dealer.
Personnel must be informed of the installations used
and how they work.
Caution!
Never operate the product if the safety and
monitoring devices have been removed or
damaged, or if they do not work.
2.9
Safety rules during operation
When operating the product, always follow the locally applica-
ble laws and regulations for work safety, accident prevention
and handling electrical machinery. To help to ensure safe work-
ing practice, the responsibilities of employees should be clearly
set out by the owner. All personnel are responsible for ensuring
that regulations are observed.
The product has moving parts. During operation, these parts
turn to pump the fluid. Certain materials in the pumped fluid can
cause very sharp edges to form on the moving parts.
Beware of rotating parts!
The rotating parts can crush and sever limbs.
Never reach into the hydraulics or the mov-
ing parts during operation. Switch off the
product and let the moving parts come to a
stop before maintenance or repair work!
2.10 Operation in an explosive atmosphere
Products marked as explosion-proof are suitable for operation
in an explosive atmosphere. The products must meet certain
guidelines for this type of use. Certain rules of conduct and
guidelines must be followed by the operator as well.
Products that have been approved for use in an explosive
atmosphere are marked as follows:
- An "Ex" symbol must be attached to the type plate!
- The information regarding the explosion-proof classification
and the explosion-proof certification must be indicated on the
type plate.
When using a product in an explosive atmosphere,
observe the information on explosion protection pro-
vided in the other chapters!
Beware of using an accessory not approved
for use in an explosive atmosphere!
If you use explosion-proof certified products
in an explosive atmosphere, the accessories
must also be approved for such use! Check
all accessories before use to verify that they
conform to this directive.
2.11 Pumped liquids
Each pumped liquid differs in respect of composition, corrosive-
ness, abrasiveness, dry matter content and in many other
aspects. Generally, our products can be used for many applica-
tions. Please note that if requirements change (density, viscos-
ity or general composition), this can also affect many
parameters of the product.
When using or replacing the product in a different pumped liq-
uid, observe the following points:
- When used in drinking water applications, all the parts that
come into contact with the fluid must be suitable for use with
drinking water. This must be checked according to local laws
and regulations.
- Products that have been operated in dirty waste water must
be cleaned thoroughly before being used for other pumped
liquids.
- Products that have been operated in sewage water and/or
fluids that are hazardous to health must be decontaminated
before being used with other pumped liquids.
It must be clarified, whether the product can be used
at all with another pumped liquid.
- If a product is operated with a lubricant or cooling fluid (such
as oil), the pumped liquid can be contaminated by these sub-
stances if the mechanical shaft seal is defective.
- It is strictly prohibited to pump explosive or highly flammable
liquids in pure form!
Danger - explosive liquids!
It is strictly prohibited to pump explosive liq-
uids (gasoline, kerosene, etc.). The products
are not designed for these liquids!
2.12 Sound pressure
Depending on the size and capacity (kW), the products pro-
duce a sound pressure of approximately 70 dB (A) to 110 dB
(A).
The actual sound pressure, however, depends on several fac-
tors. These include, for example, the installation depth, configu-
ration, fastening of accessories and pipeline, operating point,
immersion depth, etc.
Once the product has been installed, we recommend that the
operator make an additional measurement under all operating
conditions.
Caution: Wear ear protectors!
In terms of the applicable laws and regula-
tions, ear protection must be worn if the
sound pressure is greater than 85 dB (A)! The
operator is responsible for ensuring compli-
ance with these regulations!

3.1
Delivery
Upon receipt of the delivery, it is immediately checked for dam-
age and completeness. If any parts are damaged or missing,
the transport company or the manufacturer must be informed
on the day of delivery. Claims made after this date cannot be
recognized. Damage to parts must be noted on the delivery or
freight documentation.
3.2
Transport
Only the appropriate and approved fastening devices, transpor-
tation means and lifting gear may be used. These must have
sufficient load-bearing capacity to ensure that the product can
be transported safety. If chains are used they must be secured
against slipping.
The personnel must be qualified for the tasks and must follow
all national safety regulations in effect during the work.
The product is delivered by the manufacturer / shipping agency
in suitable packaging. This normally precludes the possibility of
damage occurring during transport and storage. The packag-
