Automatic float switch
If the water level rises to a certain maximum level (switch-
on point), the float will automatically switch the pump on.
If the water level drops down to a certain minimum level
during pumping (switch-off point), the float switches off
the pump.
Accessories float switch for use with a shower or bath-
tub

5.3. Electrics
Risk of electrocution!
Improper use of electricity can be fatal! All pumps
with free cable ends must be connected by a qual-
ified electrician.
A professional inspection prior to initial operation
must ensure that the required electrical protection
measures are in place.
The voltage specified in the technical data must cor-
respond with the local power supply.
Make sure that the electrical connections are locat-
ed in a flood-proof area and are protected from mois-
ture. The power cord and plug must be checked for
damage before use.
The electrical connection must be made in accordance
with the local regulations of the NEC or NFPA 70 The sup-
ply voltage and frequency are indicated on the nameplate
of the pump and the switching device.
The voltage tolerance must be between +6% to -10% of
the supply voltage.
It is important to ensure that the data provided on the
nameplate corresponds with the existing power supply.
The lifting systems require no further motor protection.
5.4. Initial operation
Never allow the pump to run dry for a prolonged time
(risk of overheating).
Before the initial operation of the plant, the provided
sleeve valves or gate valves are to be opened.
Plug the power cord into a grounded outlet, the lifting
system is now ready for use. The pump starts working as
soon as the water level has reached the starting level in
the collection container.
Once the water level reaches the stop level, the pump
switches off.
