ENGLISH
For installations in areas subject to explosion hazards, special
regulations apply!
APPLICATION
DANGER!
The pump must never be used when a person is in the water.
Submersible pumps from the MultiDrain range are suitable for
pumping slightly soiled water without stones.
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
Motor at the surface: continuous operation S1
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
WARNING!
The pump must only be connected to sockets that have been
installed properly in accordance with the regulations and are
protected with at least 10 A (slow) and RCD-safety switches
(30mA).
NOTICE! Only qualified electricians may carry out electrical
work on the pump, plug or the control unit.
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.
Some types are supplied with an open cable end. To connect to
the power supply, a control unit or a nationally approved plug
with a protective earth contact must be used.
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.

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 from the
mains supply or remove the pre-fuses of the pump controls!
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 a vertical discharge branch.
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.
Dimensions of sump
Single installation: 40 x 50 cm
Duplex installation: 40 x 70 cm
NOTICE! The floats of the level control and alarm system are
installed so that they are freely movable but not under the in-
let. Please observe the minimum distances. The controls must
only be installed in a dry and well ventilated room!
MAINTENANCE
Maintenance and inspection of this product must be carried
out in accordance with EN 12056-4.
To ensure continued reliability of service, we recommend that
you take out a service contract.
DANGER!
Before carrying out any work: Disconnect the pump and the
control unit from the mains power supply and take action to en-
sure that no one else can reconnect them to the power supply.
