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
intervals. 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 Start-Up
5.1. General
In order to prevent damage to the pump or serious injury
during installation the following points must be observed:
• Installation work may only be carried out by qualified
persons. The safety instructions must be followed at
all times.
• The pump must be inspected for damages before any
installation work is carried out.
• If you are using level control, make sure that the min-
imum water coverage is present.
• Air pockets may not be allowed to enter the pump
housing or the pipes and they must be removed with
a suitable ventilation system or a small inclination of
the pump.
• Protect the pump from frost.
• The operating area must be laid out for each machine.
You must ensure that lifting gear can be fitted without
any trouble, since this is required for assembly and
removal of the machine.
• The maximum bearing capacity must be greater than
the weight of the machine, add-on units and cable.
• The power lines of the pump must be laid in such
a way that safe operation and easy assembly/disas-
sembly are ensured.
• The power lines must be properly fastened in the
operating room to prevent the cables from hanging
down loosely. Depending on the cable length and
weight, a cable holder must be attached every 2-3m.
• The structural components and foundations must be
of sufficient stability to ensure safe and functional op-
eration. The operator or supplier is responsible for the
provision.
• Never let the unit run dry. Therefore, we recommend
installing a level control unit.
• Use defector plates for the inlet. This prevents air
from entering the pumped medium, which leads to
unfavorable operating conditions and increased wear.
