Installation and electrical
connection
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
allow the device to be fixed in a secure and functional manner. The operator is
responsible for the provision and suitability of the building/foundation!
ƒ
Check that the available consulting documents (installation plans, design of the
operating space, inflow conditions) are complete and correct.
6.3
Preparing the installation
警告
Risk of personal injury and property damage due to improper handling!
• Never set up the pump unit on unfortified surfaces or surfaces that cannot bear
loads.
• The pump should only be installed after completion of all welding and soldering
work.
• Flush the pipe system if required. Dirt can cause the pump to fail.
ƒ
The pumps (in the standard version) must be protected from the weather and
installed in a frost/dust-free, well-ventilated environment that is not potentially
explosive.
ƒ
Mount the pump in a readily accessible place. This makes it easier to complete
inspections, maintenance (e.g. mechanical seal change) or replacement in the future.
ƒ
A travelling crane or a device for attaching hoisting gear should be installed above
the set-up site of large pumps.
6.4
Setting up the pump by itself
(variant B, Wilo variant key)
When installing a pump by itself, the required coupling guard and base frame of the
pump manufacturer should be used. In any case, all components must meet the
CE regulations. The coupling guard must be compatible with EN 953.
