5 INSTAL L AT ION
In order to prevent damage to the product or serious injury dur-
ing installation, the following points must be observed:
- Installation work – assembly and installation of the machine –
may only be carried out by qualified persons. The safety
instructions must be followed at all times.
- The machine must be inspected for transport damage before
carrying out any installation work.
5.1 General
For planning and operation of technical waste water systems,
attention is drawn to the pertinent local regulations and direc-
tives for waste water technology (such as the German Associa-
tion for Water, Wastewater and Waste).
Attention is drawn to pressure surges, in particular with station-
ary installations in cases where water is pumped with longer
in kW

discharge pipes (especially with steady ascents or cross coun-
try terrain).
Pressure surges can lead to destruction of the unit/system and
noisy operation resulting from valve knocking. This can be
avoided by taking appropriate measures (e.g. non-return valves
with adjustable closure time or laying the discharge pipe in a
special way).
After pumping water containing lime, clay or cement, flush out
the product with clean water in order to prevent encrustation
and subsequent breakdowns.
If you are using level control, make sure that the minimum water
coverage is present. Air pockets must not be allowed to enter
the hydraulic housing or the pipeline system, and they must be
removed with suitable bleeding equipment and/or by inclining
the machine slightly (with a portable installation). Protect the
product from frost.
5.2 Types of installation
- Vertical stationary wet installation with suspension unit (SCA/
SVO... only)
- Vertical portable wet installation
5.3 The operating area
The operating area must be clean, free of coarse solids, dry,
frost-free and, if necessary, decontaminated. It must also be
suitable for the respective product. When working in shafts, a
second person must be present for safety reasons. If there is
danger of poisonous or asphyxiating gases forming, the neces-
sary countermeasures must be taken!
When installing in shafts, the size of the shaft and the cool-
down time of the motor must be determined by the system
planner, depending on the ambient conditions prevailing during
operation.
In order to achieve adequate cooling, units without
active cooling must be flooded completely before
being switched back on!
It must be ensured that hoisting gear can be fitted without any
trouble, since this is required for assembly and removal of the
product. It must be possible to reach the product safely in its
operating and storage locations using the hoisting gear. The
machine must be positioned on a firm foundation. For trans-
porting the product, the load-carrying equipment must be
secured to the provided lifting eyelets.
Electric power cables must be laid out in such a way that safe
operation and trouble-free assembly/dismantling are possible at
all times. The product must never be carried or dragged by the
power supply cable. When using switching devices, the corre-
sponding protection class must be observed. Switching devices
must always be mounted in such a way that they are protected
from flooding.
When used in an explosive atmosphere, it must be ensured that
the product as well as all accessories are approved for this pur-
pose of use.
The structural components and foundations must be of suffi-
cient stability in order to allow the product to be anchored
securely and functionally. The operator or the supplier is
responsible for the provision of the foundations and their suit-
ability in terms of dimensions, stability and strength!
Never let the machine run dry. The water level must never fall
below the minimum. Therefore, we recommend installing a level
control system or a dry-run protection system where there are
great variations in the level.
