A reduction in the power of the motor may permit
dry well installation under certain circumstances.
In this regard, always observed the operating
mode specifications for immersed and non-im-
mersed operation, as shown on the rating plate.

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. Careless-
ness or wearing inappropriate clothing could
result in a fall. There is a risk of fatal injury!
Take all necessary safety precautions to pre-
vent 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 opera-
tion, the unit consultant 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
and storage locations using the lifting equip-
ment. The machine must be positioned on a firm
bearing surface. For transporting the pump, the
lifting gear must be secured to the lifting eyelets
provided or the handle. When using chains, they
must be connected with a shackle to the lifting
eyelets or the handle. Lifting gear must be tech-
nically approved.
• Power supply cables must be laid out in such a
way that safe operation and trouble-free as-
sembly/dismantling are possible at all times. The
pump must never be carried or dragged by the
power supply cable. Check whether the cable

present is long enough for its cross-section and
its installation type.
• When using switchgear, the corresponding
protection class must be observed. In general,
switchgear must be overflow-proof and is to be
x
installed outside potentially explosive areas.
x
• When used in an explosive atmosphere, it must
x
be ensured that the pump and all accessories are
approved for this purpose.
-
• Structural components and foundations must be
-
of sufficient stability in order to allow the product
to be fixed securely and functionally. The operator
or the supplier is responsible for the provision of
the foundations and their suitability in terms of
dimensions, stability and strength!
• If the motor housing is to be taken out of the fluid
during operation, the operating mode for non-
immersed operation should be followed.
To keep dry motors sufficiently cooled when
they are not immersed, they must be flooded
completely before being switched back on!
• Never let the pump run dry. The water level must
never fall below the minimum. Therefore, we
recommend installing a level control system or a
dry-running protection system where there are
great variations in the level.
• Use guide and deflector plates for the fluid intake.
If the water jet reaches the surface of the water,
air will be introduced into the fluid, which can
accumulate in the pipe system. This can result in
inadmissible operating conditions and to deacti-
vation of the entire system.
• Check that the available design documentation
(installation plans, layout of the operating space,
intake ratios) is complete and correct.
• Please observe all regulations, rules and legal
requirements for working with and underneath
heavy suspended loads. Wear appropriate protec-
tive clothing/equipment.
• Please also observe the applicable national acci-
dent prevention regulations and trade association
safety provisions.
5.3.1. Attach lifting gear to the pump
Fig. 2: Attaching lifting gear correctly

2 Pump with two attachment points
Note the following points when attaching the
lifting gear:
• Only use authorised lifting gear.
• The lifting gear must have a corresponding bear-
ing capacity.
• Use 1 or 2-line lifting gear depending on the at-
tachment points on the pump.
• The lifting gear must be attached to the pump
using shackles.
• Observe the installation and operating instruc-
tions for the lifting gear with regard to permitted
use.
