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.
