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
DANGER!
The pump must never be used when a person is in the water.
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.
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

NOTICE! Only qualified electricians may carry out electrical
work on the pump, plug or the control unit.
The pump must only be connected to circuits that have been
installed properly in accordance with the regulations and are
protected with at least 10 A (slow) and RCD-safety switches
(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.
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.
