If the pump is to be stored for more than a year, consult Wilo and ask what action
should be taken to conserve the pump.

Installation and electrical con-
nection
6.1
Personnel qualifications
ƒ
Electrical work: A qualified electrician must carry out the electrical work.
6.2
Operator responsibilities
ƒ
Observe locally applicable accident prevention and safety regulations of professional
and trade associations.
ƒ
Observe all regulations for working with heavy loads and under suspended loads.
ƒ
Provide protective equipment and ensure that the protective equipment is worn by
personnel.
ƒ
Avoid pressure surges!
Pressure surges can occur in long pressure pipes. These pressure surges can lead to
the destruction of the pump!
ƒ
Structural components and foundations must be of sufficient stability in order to al-
low the device to be fixed in a secure and functional manner. The operator is re-
sponsible for the provision and suitability of the building/foundation!
ƒ
Check that the available consulting documents (installation plans, design of the op-
erating space, inflow conditions) are complete and correct.
6.3
Preparing the installation
WARNING
Improper handling involves risk of personal injury and material damage!
• Never set up the pump unit on unpaved surfaces or surfaces that cannot bear
loads.
• Flush the pipe system if required. Dirt can cause the pump to fail.
• Install only after all welding and soldering work has been completed and the
pipe system has been flushed, if required.
• Observe the minimum axial distance between a wall and the fan cover of the
motor: 200 mm + diameter of the fan cover
• Ensure air can flow freely to the heat sink of the electronic module.
ƒ
The pumps (in the standard version) must be protected from the weather and in-
stalled in a frost/dust-free, well-ventilated environment that is not potentially ex-
plosive.
ƒ
Mount the pump in a readily accessible place. This makes it easier to carry out in-
spections, maintenance (e.g. mechanical seal change) or replacement in the future.
ƒ
A travelling crane or device for attaching hoisting gear should be installed above the
set-up location of large pumps.
6.4
Installing the pump unit on a base
CAUTION
Danger of property and material damage!
A missing foundation or incorrect installation of the unit on the base can lead to a
malfunction of the pump. Incorrect installation is not covered by the warranty.
• Only have the pump unit installed by qualified personnel.
• A professional from the concrete sector must be hired for all base work.
