Operator responsibilities

▪ Observe the locally applicable accident prevention and
safety regulations of trade associations.
▪ Observe all regulations for working with heavy loads and
under suspended loads.
▪ Provide protective equipment and ensure that the pro-
tective equipment is worn by personnel.
▪ Observe local regulations on the latest technology for
wastewater and sewage disposal (without faeces).
▪ Avoid pressure surges!
Pressure surges can occur in long pressure pipes with
steep terrain. These pressure surges can lead to the de-
struction of the pump!
▪ Ensure the cooling time of the motor depending on the
operating conditions and the size of the pump chamber.
▪ Structural components and foundations must be of suf-
ficient stability in order to allow the device to be fixed in
a secure and functional manner. The operator is respons-
ible for the provision and suitability of the building/
foundation!
▪ Check that the available consulting documents (installa-
tion plans, design of the operating space, inflow condi-
tions) are complete and correct.

Installation

DANGER
Risk of fatal injury due to dangerous lone
working practices!
Work in chambers and narrow rooms as well as work
involving risk of falling are dangerous work. Such
work may not be carried out autonomously! A second
person must be present for safety reasons.
WARNING
Hand and foot injuries due to lack of protect-
ive equipment!
Danger of (serious) injuries during work. Wear the fol-
lowing protective equipment:
• Safety gloves for protection against cuts
• Safety shoes
• Safety helmet must be worn if lifting equipment
are used!
Installation and operating instructions Wilo-Padus UNI
Installation and electrical connection
NOTICE
Use only properly functioning lifting equip-
ment!
Use only properly functioning lifting equipment to lift
and lower the pump. Ensure that the pump does not
become jammed during lifting and lowering. Do not
exceed the maximum bearing capacity of the lifting
equipment! Check that lifting equipment is function-
ing properly before use!
NOTICE
Emerging of the motor during operation
If the motor emerges during operation, observe the
instructions for "non-immersed operating mode"! To
ensure the necessary cooling of the motor for con-
tinuous duty, the motor must be completely im-
mersed before re-activation!
▪ Prepare operating space/installation location as follows:
– Clean, free of coarse solids
– Dry well
– Frost-free
– Decontaminated
▪ Take immediate countermeasures if there is a build-up
of toxic or suffocating gases!
▪ Use the handle for lifting, lowering and transporting the
pump. Never carry or drag the pump by the power supply
cable!
▪ It must be possible to attach lifting equipment safely.
The storage place and the operating space/installation
site must be accessible with the lifting equipment. The
set-down location must have a solid bearing surface.
▪ Attach the lifting gear to the handle using a shackle. Only
use lifting gear which has been technically approved.
▪ The routed power supply cables must allow safe opera-
tion. Check whether the cable cross-section and the
cable length are sufficient for the selected installation
type.
▪ The corresponding IP class must be observed when using
switchgear. Install the switchgear overflow-proof and
outside potentially explosive areas!
▪ Avoid air intake into the fluid, use baffles or deflector
plates for the inlet. Air which has entered the system can
collect in the pipe system and lead to impermissible op-
erating conditions. Air pockets must be removed via
ventilation systems!
▪ A dry run of the pump is prohibited! Avoid air pockets in
the hydraulics housing or in the pipe system. Ensure the
