6. Electrical connection
The unit is equipped with a mains connection cable and a mains plug. It must only be replaced by qualified staff to
avoid any danger. Please do not use the mains connection cable to carry the pump, and do not use this cable to
pull off the plug from the socket, either. Protect the mains connection cable and mains plug from heat, oil or sharp
edges.
The values stated in the technical details have to correspond to the mains voltage. The person
responsible for the installation has to make sure that the electrical connection is earthed in
compliance with the applicable standards.
The electrical connection has to be equipped with a highly sensitive residual current circuit-
breaker (FI switch): ∆ = 30 mA (DIN VDE 0100
-739).
If extension cables are used, their cross-section must not be smaller than that of rubber-
sheathed cables of the H05RN-F (3 x 1,0 mm²) short code. The mains socket and the plug-
and-socket elements have to be in splashwater-proof design.
7. Putting into operation
Nobody must be in the water while the pump is running.
The pump must only be operated in the performance range indicated on the type plate.
Dry-running - i.e. operating the pump without discharging water - is to be avoided since the
absence of water may cause the pump to run hot. This may cause considerable damage on
the device.
Please make sure that the electrical plug connections are in the flood-proof area.
As long as the device is connected to th
e electrical mains, one must never reach with one’s
hands into the opening of the pump.
Please inspect the pump visually prior to each use. This applies in particular to the mains connection line and the
mains plug. Make sure that all screws are firmly tightened, and verify the perfect condition of all connections. A
damaged pump must not be used. In any case of damage, the pump has to be inspected by qualified service
staff.
Each time the pump is put into operation, please make sure that the pump is set up securely and firmly standing.
The pump can be operated optionally in automatic or manual operation. However, pumping the liquid down to the
minimum intake level as indicated in the technical data is only possible with manual operation. With automatic
operation, the lowest attainable residual water level corresponds to the cut-out level specified in the technical
data.
7.1.
Automatic operation
Especially in automatic operation, pleased take care that the pump is positioned vertically so
as to ensure the free motion of the integrated float switch. Please assure yourself that the
pump will cut out as the water level decreases and reaches the cut-out level.
The pump is equipped with an integrated float switch which will cause the unit to cut in or cut out as a function of
the water level. If the water level reaches or drops below the cut-out level, the pump will cut out. If the water level
reaches or raises above the starting level, the pump will cut in. The cut-in and cut-out levels are indicated in the
technical data and cannot be altered.
For automatic operation, please set the lever on the pump to the “A
uto
” position.
To put the unit into operation, please plug the mains plugs into a 230V AC socket. If the water level has reached
or exceeded the cut-in level, the pump will start to run immediately.
To stop the operation of the pump, please pull the mains plug off the socket.
7.2.
Manual operation
In manual operation, the integrated float switch is deactivated. This means that the pump will run permanently as
long as it is connected to the electrical mains.
