Unauthorised operating methods
The operational safety of the supplied equipment is only guar-
anteed if the equipment is used for its intended purpose. The
limiting values given in the "Technical Data" section may not be
exceeded under any circumstances.
Instructions regarding accident prevention
Before commencing servicing or maintenance works, cordon
off the working area and check that the lifting gear is in perfect
condition.
Never work alone. Always wear a hard hat, safety glasses and
safety shoes and, if necessary, a suitable safety belt.
Before carrying out welding works or using electrical devices,
check to ensure there is no danger of explosion.
People working in wastewater systems must be vaccinated
against the pathogens that may be found there. For the sake of
your health, be sure to pay meticulous attention to cleanliness
wherever you are working.
Make sure that there are no toxic gases in the working area.
Observe the health and safety at work regulations and make
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 of the MultiDrain series are suitable for
pumping wastewater, rainwater, groundwater, seepage water
or drainage water with admixtures of up to 10 mm grain size.
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 circuits 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.
