ENGLISH
The pump must only be connected
to outlets that are installed accord-
ing to specifications and are protected with at
least 10 A (slow) and FI-safety switches
(30mA).
APPLICATION
Submersible pumps from the US se-
ries are suitable for pumping domestic
waste water without stones.
When using the pumps, the relevant na-
tional laws, regulations and stipulations
must be adhered 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 utilisation conditions,
further regulations must be observed
(e.g. VDE 0100 in Germany, part 701:
bathrooms and shower rooms; part
702: swimming pools and fountains and
part 737: outdoor use).
Where no explosion protection is stipu-
lated for the pumping of foul wastewa-
ter at the installation location, US 75,
US 105, US 155 may also be used.
Modes of operation
with the pumped medium at a tempera-
ture of 104°F (40°C) or 194°F (90°C)
in the case of HE and HES hot water
pumps:
Motor submersed: continuous opera-
tion S1
Motor at the surface: short duration
operation S2; see “Technical Data”
Motor at the surface; intermittent op-
eration S3; see “Technical Data”
The submersible pump is frost-resistant
down to -20°C when stored in dry condi-
tions. When installed, however, it must
not be allowed to freeze in the water.
Transport
The pump must always be lift-
ed by the handle and never by
the power supply cable! The
pump should only be lowered into deep-
er chambers or pits using a rope or
chain.

ELECTRICAL
CONNECTION
Only qualified electricians may
carry out electrical works to
the pump or the controls.
The relevant standards (such as EN
standards), country-specific regula-
tions (such as VDE in Germany), and the
regulations of the local power supply
companies must be observed.
Attention !
Never put the mains plug or
a free lead end in water! If water gets
into the plug, this can cause malfunc-
tions and damage.
Observe the operating voltage (see the
type plate)!
The pump is provided with a wind-
ing thermostat. In case of unaccept-
ably high temperatures it switches off
the pump to protect it against possible
damage. Unacceptably high tempera-
tures may result e.g. from dry running
or mechanical or electrical overload.
The pump is switched on again
automatically after cooling
down - risk of injury! For this
reason, always disconnect the device
from the mains before remedying the
fault! In order to do this, unplug the
pump from the mains supply or remove
the pre-fuses of the pump controls!
US 62 to US 105
Observe the operating voltage (see the
type plate)! Only connect the pump to
sockets that have been installed prop-
erly in accordance with the regulations
and are fitted with a 16 A (delay) fuse.
Pumps without built-in level control can
also be operated automatically through
the use of our level controls. Our ready
to connect level controls can be in-
stalled without specific electrotechnical
skills.
US 151 to US 253
Observe the operating voltage (see the
type plate)! Only connect the pump to
sockets that have been installed prop-
erly in accordance with the regulations
and are fitted with a 16 A (delay) fuse.
The pump must only be operated with
the standard motor protection plug.
Models without motor protection plug
must only be operated using the level
controls with integrated motor pro-
tection that are approved by JUNG
PUMPEN. These pumps must be con-
nected by a qualified electrician.
