7 Installation and electrical connection
Installation and electrical connection should be
carried out in accordance with local regulations
and only by qualified personnel!
WARNING! Risk of personal injury!
The relevant accident precaution regulations
must be observed.
WARNING! Risk of electric shock!
Potential dangers caused by electrical energy
must be excluded.
Local or general regulations [e.g. NEC, IEC, VDE,
etc.] and directives from local energy supply
companies are to be followed.
7.1 Installation
The pump is designed for the following installa-
tion types: stationary and transportable wet-well
installation.
CAUTION! Risk of damage to the pump!
The pump must only be suspended by a chain
from the handle provided. Never suspend or
carry using the cable!
• The pump must be installed in a frost-free place.
• The shaft must be free from coarse solids (e.g.
building rubble) prior to installation and commis-
sioning.
• The pipes must be assembled stress-free. The
pipes must be attached in such a way that the
pump does not bear the weight of the pipes.
• In order to protect against possible reflux from the
public sewage system, the pressure pipeline
should be formed as a "pipe loop". It must be
placed over the locally set reflux level (usually
street level).
• When assembling the pump for stationary use, a
non-return valve and a shut-off valve with full
flow cross-section should be built into the pres-
sure piping. In the case of double pumps these fit-
tings should be installed for each pump.
NOTE: Optimally, the valves should be installed
outside of the pump, in a separate shaft (valves
shaft). Where this is not feasible, the valves should
not be connected directly to the discharge side or
the pipe bend. A device for venting the pump
should be provided, otherwise the insulating air
cushion may not open the non-return valve.
• "Original Wilo accessories" are recommended to
ensure the fault-free operation of the pump /
installation.

tomer.
Pos. 2: Backflow preventer with unrestricted
passage, cleaning opening, ventilating
device and assembly accessories
Pos. 3: Shut-off valve with fitting accessories
Pos. 4: Pipe bend with fitting accessories
Pos. 6: Chain
See catalogue for details.
• The fixed pipe connections on the pressure side
are to be provided by the customer.
• Fit and align the foot bend on the base of the shaft
with the base fastening accessories.
• Connect the pressure piping to the foot bend with
the required fittings (accessories).
• Attach the pump mounting and profiled gasket to
the pump pressure pipe connection.
"
• Attach the ¾ guide pipe (to be provided by the
customer) to the foot bend.
• Hang the pump from the guide pipe and carefully
lower it on the chain. The pump will lock into the
right operating position automatically and seal the
delivery connection on the foot bend by its own
weight.
• Fasten the chain to the guide pipe mounting with
a shackle (provided by the customer).
7.1.2 Transportable wet-well installation
CAUTION! Risk of damage to the pump!
The pump should be prevented from falling over
