5 Installation

In order to prevent damage to the product or serious
injury during installation, the following points must be
observed:
• Installation work – assembly and installation of the
machine – may only be carried out by qualified per-
sons. 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 regu-
lations and directives for waste water technology (such
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).
Installation and operating instructions Wilo-EMU KS.../KS...Ex
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 clo-
sure 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
• 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!
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/disman-
tling are possible at all times. The product must never
be carried or dragged by the power supply cable. When
using switching devices, the corresponding 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 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!
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 con-
ditions for the unit. As a result of cavitation, the prod-
uct does not run smoothly and is subjected to
increased wear.
