Electrical Connection - Pentair Jung Pumpen MULTIDRAIN UV 620-1 Instructions De Service

sure that a first-aid kit is to hand.
In some cases, the pump and the pumping medium may be hot
and could cause burns.
For installations in areas subject to explosion hazards, special
regulations apply!
APPLICATION
Submersible pumps from the MultiDrain range are suitable for
pumping slightly soiled water without stones.
Continuous operation is possible if the yellow ring remains im-
mersed.
NOTICE! The pump must not run dry! Otherwise engine dama-
ge may occur.
Use of the pumps is subject to relevant national laws, regula-
tions and local requirements such as:
• Domestic contaminated water 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; part 704: Construction sites and part 737: outdoor use).
Temperatures
The pumped medium must have a temperature of max 40°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 chain.

ELECTRICAL CONNECTION

NOTICE! Only qualified electricians may carry out electrical
work on the pump, plug or the control unit.
WARNING!
The pump must only be connected to outlets that are installed
according to specifications and are protected with at least 16 A
(slow) and RCCB circuit breakers (30mA).
Current applicable standards (such as EN standards), national
regulations (such as VDE in Germany), and the regulations of
the local power supply companies must be complied with.
The pumps are supplied with an open cable end (not UV 620-
1S). To connect to the power supply, a control unit or a nation-
ally approved motor protection plug with a protective earth
contact must be used.
NOTICE! In order to protect the motor, 3-phase pumps must
be operated via a thermally delayed motor overload protection
switch (or motor protection plug).
NOTICE! Never put the mains plug or a free lead end in water!
If water gets into it, this can cause malfunctions and damage.
Observe the operating voltage (see 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.
WARNING!
The pump is switched on again automatically after cooling
down - risk of injury! Therefore, always disconnect the pump
from the power supply before removing the cause of the mal-
function! In order to do this remove the pre-fuses!
Pumps without built-in level control can also be operated auto-
matically through the use of our level controls.
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.
INSTALLATION
The pump must be installed as shown in the examples. For in-
stallations in accordance with EN 12056-4, the pressure pipe
must be laid in a loop above the local backflow level and pro-
tected with a non-return valve in accordance with EN 12050-4.
A correspondingly larger diameter pipe should be used for
longer pressure pipelines to avoid pipe friction losses.
The MultiDrain pumps have both a horizontal and a vertical
discharge branch. The branch that is not used must be sealed
with the plug. During operation, the pump is automatically ven-
tilated via this plug.
In contrast to pumps with built-in level control, the ON and OFF
switching heights of pumps without built-in level control are
variable by the use of a separate level control.
NOTICE! If the pump is malfunctioning, part of the contents of
the oil reservoir could escape into the pumping medium.
