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.
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
Pump runs but does not pump
•
Empty the pressure pipe or hose to allow the non-return
valve to open and the air to escape from the pump housing.
Impeller blocked
•
Solids and fibrous matter have become 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
