ENGLISH
For installations in areas subject to explosion hazards, special
regulations apply!
APPLICATION
Submersible pumps from the US series are suitable for pump-
ing domestic waste water without stones.
When using the pumps, the relevant national 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: bath-
rooms and shower rooms; part 702: swimming pools and foun-
tains and part 737: outdoor use).
Where no explosion protection is stipulated for the pumping of
foul wastewater at the installation location, US 75, US 105, US
155 may also be used.
Modes of operation
with the pumped medium at a temperature of 104°F (40°C) or
194°F (90°C) in the case of HE and HES hot water pumps:
Motor submersed: continuous operation S1
Motor at the surface: short duration operation S2; see “Tech-
nical Data”
Motor at the surface; intermittent operation S3; see “Techni-
cal Data”
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.
ELECTRICAL CONNECTION
NOTICE!
NOTICE!
Only qualified electricians may carry out electrical
works to the pump or the controls.
WARNING!
The pump must only be connected to outlets that are installed
according to specifications and are protected with at least 10 A
(slow) and FI-safety switches (30mA).
WARNING!
Before carrying out any works: disconnect the pump and the
controls from the mains and take steps to ensure that it cannot
be emergized again.
The relevant standards (such as EN standards), country-spe-
cific regulations (such as VDE in Germany), and the regulations
of the local power supply companies must be observed.
NOTICE!
NOTICE!
Never put the mains plug or a free lead end in water!
If water gets into the plug, this can cause malfunctions and da-
mage.
Observe the operating voltage (see the type plate)!
The pump is provided with a winding thermostat. In case of
unacceptably high temperatures it switches off the pump to
protect it against possible damage. Unacceptably high tem-
peratures may result e.g. from dry running or mechanical or
electrical overload.
CAUTION!
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 con-
nect the pump to sockets that have been installed properly in
accordance with the regulations and are fitted with a 16 A (de
-
lay) fuse.
Pumps without built-in level control can also be operated au-
tomatically through the use of our level controls. Our ready to
connect level controls can be installed without specific elec
-
trotechnical skills.
US 151 to US 253
Observe the operating voltage (see the type plate)! Only con-
nect the pump to sockets that have been installed properly in
accordance with the regulations and are fitted with a 16 A (de
-
lay) fuse.
The pump must only be operated with the standard motor pro-
tection plug. Models without motor protection plug must only
be operated using the level controls with integrated motor
protection that are approved by JUNG PUMPEN. These pumps
must be connected by a qualified electrician.
The overload protection (only for D and DS) must be set to the
nominal current of the pump (see type plate) + 10%. If the mo-
tor protection plug or the level control require to be opened in
order to reset or set the overload protection, this must only be
done by a qualified electrician!
If there is a blockage in the pump, the overload protection may
be triggered. After rectifying the fault the "reset" button on the
motor protection plug must be pressed to switch the pump on
again. Pumps which are operated with a separate level control
have the overload protection in the level control.
Rotational direction
The rotational direction must be checked before installation! If
the rotational direction is correct, the start-up jolt should be in
the opposite direction to the rotational direction arrow on the
motor housing. The wrong rotational direction is also indicated
if the pump performs inadequately when installed, or if loud
noises can be heard during operation. If the rotational direc-
tion is wrong, 2 phases of the supply cable must be swapped
over.
CAUTION!
The start-up jolt can be very forceful.
