Beware of electrical current!
Damaged power supply cables can cause fatal inju-
ry! Defective cables must be replaced by a qualified
electrician immediately.
Beware of damp!
Moisture penetrating cables can damage them and
render them useless. Therefore, never immerse ca-
ble ends in the pumped fluid or other liquids.
• The machine must be protected from direct sunlight,
heat, dust, and frost. Heat and frost can cause con-
siderable damage to propellers, rotors and coatings.
• The rotors or propellers must be turned at regular in-
tervals. This prevents the bearing from locking and
the film of lubricant on the mechanical shaft seal is re-
newed. This also prevents the gear pinions (if present
on the product) from becoming fixed as they turn and
also renews the lubricating film on the gear pinions
(preventing rust film deposits).
Beware of sharp edges!
Sharp edges can form on rotors and propellers.
There is a risk of injuries. Wear protective gloves.
• If the product has been stored for a long period of
time it should be cleaned of impurities such as dust
and oil deposits before start-up. Rotors and propellers
should be checked for smooth running, housing coat-
ing and damage.
• After storage longer than one year the oil of motor
and, if necessary the gear have to be changed. This
is also necessary if the product never had run (natural
deterioration of mineral oil).
Before start-up, the filling levels (oil, cooling fluid
etc.) of the individual products should be checked and
topped up if required. Please refer to the machine data
sheet for specifications on filling. Damaged coatings
should be repaired immediately. Only a coating that
is completely intact fulfills the criteria for intended
usage!
If these rules are observed, your product can be stored
for a longer period. Please remember that elastomer parts
and coatings become brittle naturally. If the product is
to be stored for longer than 6 months, we recommend
checking these parts and replacing them as necessary.
Please consult the manufacturer.

4.4. Returning to the supplier

Products which are delivered to the plant must be clean
and correctly packaged. In this context, clean means
that impurities have been removed and decontaminat-
ed if it has been used with materials which are hazard-
ous to health. The packaging must protect the product
against damage. Please contact the manufacturer before
returning!

5. Installation and initial commissioning

5.1. General

To avoid damage to the lifting unit during installation and
operation, the following points must be observed:
• The installation work must be performed by qualified
personnel, in compliance with safety regulations.
• The pump must be inspected for damage prior to in-
stallation.
• For level controls, pay attention to the minimum wa-
ter coverage.
• Air bubbles in the pump housing and pipework must
be avoided (by suitable ventilation devices or a slight
incline of the pump).
• Protect the pump from frost.
• The operating room must be designed for the partic-
ular machine. This also means that a lifting device for
assembly/disassembly can be mounted, from which
the installation space of the pump can be reached
without risk.
• The lifting device must have a maximum load capaci-
ty which is greater than the weight of the pump with
attachments and cable.
• The power lines of the pump must be laid in such a
way, that a safe operation and easy assembly/disas-
sembly is ensured.
• The power lines must be fixed properly in the operat-
ing room to prevent the cable from hanging loosely.
Depending on the cable length and weight, a cable
holder must be attached every 2-3 m.
• The foundation/structure
strength for secure and functionally correct fastening
of the pump. The operator is responsible for this.
• A dry run is strictly prohibited. We recommend a level
control for that.
• Use baffles for the inlet. This prevents air entry into
the pumping medium, which can lead to unfavorable
operating conditions and result in increased wear.
