INSTALLATION

• The pump must be protected from direct sunlight,
heat, dust, and frost.
• The impellers must be turned at regular intervals.
This prevents the bearings from jamming and
renews the film of lubricant on the mechanical
shaft seal.
BEWARE of sharp edges!
Sharp edges can form on impellers and hy-
draulic ports. There is a risk of injuries! Wear
the necessary protective clothing, e.g. safety
gloves.
• If the pump has been stored for a long period
of time, it should be cleaned of impurities such
as dust and oil deposits prior to commissioning.
Impellers should be checked for smooth opera-
tion. The housing coatings should be checked for
damage.
Prior to commissioning, the fill level in the
sealing chamber should be checked and topped
up, if necessary!
Damaged coatings should be repaired immedi-
ately. Only a coating that is completely intact
fulfills the criteria for intended use!
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. 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.
• 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 wastewa-
ter systems, observe the pertinent local regula-
tions and directives for wastewater technology
(such as those of the German Association for
Water, Wastewater and Waste).
Note that pressure surges can occur, in partic-
ular with stationary installations where water is
pumped with longer discharge pipes (especially
Installation and operating instructions Wilo-EMU FA+T-Motor
with steady ascents or steep terrain). This can
result in the destruction of the pump/system.
If you are using level control, make sure that the
minimum water coverage is present. Air pockets
in the hydraulic housing or pipeline system must
be avoided at all costs and must be removed
using a suitable ventilation system. Protect the
pump from frost.

5.2. Types of installation

If the output of the motor is reduced, dry well
installation may sometimes be possible.
Always refer to the information on the rating
plate regarding immersed and non-immersed
operation!
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 shaft. Carelessness 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 area must be clean, free of coarse
solids, dry, frost-free and, if necessary, decon-
taminated. It must also be suitable for the partic-
ular pump.
• 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 countermeasures must be taken!
• The system designer is to determine the shaft
size and cooling time for the motor as a function
of the ambient conditions that are prevalent
during operation.
