English
• The pump is not allowed to be stored in rooms
in which welding work is carried out, because
the resulting gases or radiation can damage the
elastomer components and coating.
• 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. Heat or frost can cause seri-
ous damage to impellers and coatings!
• 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
the housing coatings for damage.
Prior to commissioning, the fill level in the
sealing 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.
42
• The pump must be inspected for transport dam-
age before any installation work is carried out.

5.1. General

For planning and operation of technical sewage
systems, 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).
Pressure surges can result in destruction of the
pump/system and noise pollution due to flap
knock. Pressure surges can be prevented by ap-
plying suitable measures (e.g. non-return valves
with an adjustable closing time or special routing
of the discharge pipeline).
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 and/or placing the
pump at a slight angle (if installed as a portable
pump). Protect the pump from frost.

5.2. Installation methods

• Vertical stationary wet well installation with
suspension unit
• Vertical portable wet well installation with pump
foot
5.3. Installation
DANGER of falling!
When installing the pump and its accessories,
work is sometimes performed directly at the
edge of the basin or pump chamber. Care-
lessness or wearing inappropriate clothing
could result in a fall. There is a risk of fatal
injury! Take all necessary safety precautions
to prevent this.
The following information should be taken into
consideration when installing the pump:
• This work must be carried out by a qualified
person and electrical work must be carried out by
an electrician.
• The operating space must be clean, free of
coarse solids, dry, frost-free and, if necessary,
decontaminated. It must also be suitable for the
particular pump.
• When working in pump chambers, a second per-
son must be present for safety reasons. If there is
a risk of poisonous or asphyxiating gases forming,
the necessary precautions must be taken.
• Depending on the ambient conditions in oper-
ation, the unit planner must select the chamber
size and motor cooling time accordingly.
• Ensure that lifting equipment can be fitted
without any trouble, since this is required for
assembly and removal of the pump. It must be
possible to reach the pump safely in its operating
