should be stored in a safe place for reuse if the
product is frequently used at different locations.
4.3. Storage
Newly supplied pumps are prepared so that they
can be stored for at least 1 year. The pump should
be cleaned thoroughly before it is put into tem-
porary storage.
The following should be taken into consideration
for storage:
• Place the pump on a firm bearing surface and se-
cure it against slipping and falling over. Submers-
ible sewage pumps are stored horizontally.
DANGER due to falling over!
Never set the pump down if unsecured. If the
pump falls over, this may lead to injuries!
• The pumps can be stored at temperatures down
to -15 °C. The store room must be dry. We recom-
mend a frost-protected room for storage with a
temperature between 5 °C and 25 °C.
• Suction and pressure connections must be sealed
securely to prevent contamination getting in.
• All power supply cables must be protected
against kinking, damage and moisture ingress.
ELECTRICAL hazard!
Damaged power supply cables can cause fatal
injury! Defective cables must be replaced by a
qualified electrician immediately.
BEWARE of moisture!
Moisture penetrating the cable will damage
both the pump and the cable. Never immerse
the cable end in fluid and always protect it
from moisture.
• The pump must be protected from direct sunlight,
heat, dust, and frost.
• The impellers should be checked at regular inter-
vals. This presents jamming of the bearings and it
renews the film of lubrication on the mechanical
seal.
BEWARE of sharp edges!
Sharp edges can form on the impellers and
hydraulic openings. There is a risk of injury!
Wear the necessary protective clothing, such
as protective gloves.
• If the pump has been stored for a long period of
time, it should be cleaned of impurities such as
dust and oil residue before commissioning. Check
that the impellers move freely and check the
housing coatings for damage.
Prior to commissioning, the fill level in the seal-
ing chamber should be checked and topped up,
if necessary!
Damaged coatings must be repaired immedi-
ately. Only an intact coating fulfils its intended
purpose.

Please note that elastomer parts and coatings
become brittle over time. If the product is to be
stored for longer than 6 months, we recommend
checking these parts and replacing them as nec-
essary. Consult the manufacturer for details.
4.4. Return delivery
Pumps that are returned to the factory must be
properly packaged. This means that impurities
have been removed from the pump and that it has
been decontaminated if used with fluids that are
hazardous to health.
For shipping, the parts must be packed in tear-
proof plastic bags of sufficient size in such a
manner that they are tightly sealed and leak-
proof. Furthermore, the packaging must protect
the pump from damage during transportation.
If you have any questions, please contact the
manufacturer!
5. Installation
In order to prevent damage to the product or seri-
ous injury during installation, the following points
must be observed:
• Installation work – assembly and installation of
the pump – may only be carried out by qualified
persons. The safety instructions must be followed
at all times.
• The pump must be inspected for transport dam-
age before any installation work is carried out.
5.1. General
For design and operation of technical sewage sys-
tems, observe the pertinent local regulations and
directives for sewage technology (such as those
of the German Association for Water, Wastewater
and Waste).
Note that pressure surges can occur, in particu-
lar with stationary installations where water is
pumped with longer discharge pipes (especially
with steady ascents or steep terrain). This can
result in the destruction of the pump/system.
If you are using level control, make sure that the
minimum water coverage is present. Air pockets
in the hydraulic housing or piping system must be
avoided at all costs and must be removed using
a suitable ventilation system. Protect the pump
from frost.
5.2. Installation methods
• Vertical stationary wet well installation with
suspension unit
• Vertical portable wet well installation with pump
support foot
• Vertical stationary dry well installation
