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.
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.
Dimensions of sump
Single installation with pump base: 40 x 50 cm
Single installation with guide rail system: 40 x 70 cm
Duplex installation: 70 x 70 cm
Example of single installation with guide rail system
Installation: Fix the coupling base firmly to the floor of the col-
lection chamber using wall plugs and then mount the guide rail. Next, install
the pressure pipe including the necessary fittings, such as the non-return
valve and shut-off valves.
Finally, fit the pump with the screwed-on coupling catch onto the guide rail
and lower it into place using a chain fixed to the handle.
Example of duplex installation
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.
WARNING!
Check the plug and the mains cable for signs of mechanical and chemical
damage. Damaged or kinked cables must be re-placed by the manufacturer.
NOTICE! When using a chain to lift the pump, please observe the relevant
national regulations regarding accident preventi-on. Lifting gear must be
checked regularly by an expert in ac-cordance with the legal regulations.
Cleaning
The inlet strainer prevents coarse dirt from entering the pump. Regular
cleaning of the float and the foot strainer ensures opti-mum performance and
operation.
If the impeller needs to be cleaned due to blocking or clogging, remove the
screws on the underside of the pump and then re-move the foot strainer.
Check and clean the ventilation hole in the sealing plug that is fitted in the
unused discharge branch.

QUICK TIPS FOR REMEDYING FAULTS
-
Pump does not work
- • Check mains current (do not use a pin gauge)
• Fuse faulty = may be too weak (please refer to Electrical Connection)
• Mains supply cable damaged = repair to be carried out by manufacturer only
- • Check mains current (do not use a pin gauge)
-
Pump runs but does not pump
Empty the pressure pipe or hose to al-low the non-return valve to open and the air to escape from the pump hous-ing. -
Impeller blocked
Solids and fibrous matter have be-come lodged in the pump housing = clean -
Decreased pumping performance
- Pump housing obstructed = clean
- Impeller worn = replace
- Wrong direction of rotation (for a three-phase current) = ask a qualified electrician to change 2 phases of the supply line
