as the German Association for Water, Wastewater and
Waste).
Attention is drawn to pressure surges, in particular with
stationary installations in cases where water is pumped
with longer discharge pipes (especially with steady
ascents or cross country terrain).
Pressure surges can lead to destruction of the unit/sys-
tem 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 pre-
vent encrustation and subsequent breakdowns.
If you are using level control, make sure that the mini-
mum water coverage is present. Air pockets must not
be allowed to enter the hydraulic housing or the pipe-
line system, and they must be removed with suitable
bleeding equipment and/or by inclining the machine
slightly (with a portable installation). Protect the prod-
uct from frost.

5.2 Types of installation

• Vertical stationary wet installation with suspension unit
(TP... 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 necessary counter-
measures 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 condi-
tions prevailing during operation.
To keep dry motors sufficiently cooled when they
are not submerged, they must be flooded com-
pletely 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 transporting 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/dis-
mantling are possible at all times. The product must
never be carried or dragged by the power supply cable.
When using switching devices, the corresponding pro-
tection 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 purpose of use.
The structural components and foundations must be
of sufficient 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 founda-
tions and their suitability in terms of dimensions, sta-
bility and strength!
Never let the machine run dry. The water level must
never fall below the minimum. Therefore, we recom-
mend installing a level control system or a dry-run pro-
tection system where there are great variations in the
level.
Use guide and deflector plates for the pumped liquid
intake. If the water jet reaches the surface of the water,
air will be introduced into the pumped liquid. This will
lead to unfavorable current and pumping conditions for
the unit. As a result of cavitation, the product does not
run smoothly and is subjected to increased wear.
5.4 Installation
Danger of falling!
When installing the product and its accessories,
work is sometimes performed directly at the
edge of the basin or shaft. Carelessness and/or
wearing inappropriate clothing could result in a
fall. There is a risk of fatal injury! Take all neces-
sary safety precautions to prevent this.
The following information must be observed when
installing the product:
• This work must be carried out by a qualified person and
electrical work must be carried out by an electrician.
• Lift the unit by the handle or lifting eyelets, never by
the power supply cable. When using chains, they must
be connected with a shackle to the lifting eyelets or
the carrying handle. Fastening devices must be techni-
cally approved.
• Check that the available planning documentation
(installation plans, layout of the operating area, intake
ratios) is complete and correct.
If the motor housing is to be taken out of the
pumped liquid during operation, the operating
mode for emerged operation should be followed.
If this operating mode is not specified, operation
with an emerged motor housing is strictly forbid-
den.
Never let the machine run dry. We recommend
that dry-run protection be installed. If fluid levels
deviate dramatically, a dry-run protection must
be installed.
Check whether the cross section of the cable
used is sufficient for the required cable length
(see the catalog and planning documents or con-
sult Wilo customer service for more information).
• Please observe all regulations, rules and legal require-
ments for working with and underneath heavy sus-
pended loads.
• Wear appropriate protective clothing/equipment.
