Pentair U3 K Originalbetriebsanleitung Seite 11

APPLICATION
Submersible pumps from the U3, U5 and
U6 series are suitable for pumping domes-
tic waste water without stones. This includes
also water from household dishwashers and
household washing machines.
The U3 K spezial can also pump aqueous solu-
tions with up to 10% salt content and conden-
sate from gas condensing boilers.
The U6 can also pump ground water, drainage
silage liquor and liquid manure.
In outdoor applications, only pumps
with at least a 10-metre mains cable
must be used.
When using the pumps, the relevant national
laws, regulations and stipulations must be ad-
hered to, for example:
• Domestic contaminated and waste water
(e.g. EN 12056 in Europe)
• Installation of low voltage systems
(e.g., VDE 0100 in Germany)
For non-standard utilization conditions, further
regulations must be observed (e.g. VDE 0100
in Germany, part 701: bathrooms and shower
rooms; part 702: swimming pools and foun-
tains and part 737: outdoor use).
Temperatures
The pumped medium must have a temperature
of max 35°C.
The submersible pump is frost-resistant down
to -20°C when stored in dry conditions. When
installed, however, it must not be allowed to
freeze in the water.
Transport
The pump must always be lifted by
the handle and never by the power
supply cable! The pump should only
be lowered into deeper chambers or pits using
a rope or chain.
