The floats act as a break contact. If the top float is
‘dry’, the water level behind the drum is too low
because the mesh is clogged: the pump pumps
away more water than is being supplied through
the bottom drains/skimmer. The electronics will
switch and the filter will rinse.
The top sensor can only be adjusted correctly when
the system is commissioned.
The water level for the drum will then drop. Now,
the top float must not be set lower than 10 cm
below the water level inside the drum. By
preference, this difference level between the inside
and outside of the drum should not be more than 8
cm
during
operation. If the difference in level is
too great, the drum will turn heavily and the load
exerted on the drum filter motor will be high. If the
The pressure side of the pump must be connected
to the pipe to which the nozzles have been
connected. Ensure that the connection on the
pressure side is good and properly sealed because
the pressure of the pump is high (up to 5 bar). Do
not therefore use sewer PVC but high-pressure
PVC that can withstand at least 10 bar.
The waste pump plug must be connected to the
control electronics in the ‘RINSE PUMP’ plug
connection.
difference in level is too little, the rinse frequency
will be too high.

Safety float
The bottom float is for protection. If the water level
continues to drop, the system will be switched off
by the electronics. If the system pump and UV unit
are also connected on the plug connections for this
purpose of the electronics (‘PUMP’ and ‘UV-C’), they
will also be switched off. This will ensure that
neither the pump nor the UV will be without water.
Waste pump connection
7.2.3. Connecting flushing pump
The waste pump is already included with the Drum
and it is positioned outside the filter. There is not
already a connection for the suction side of the, but
you can create a connection at a different place as
long as the supply of the rinse water is installed
after the drum filter so that the waste pump has
clean water and the nozzles cannot be obstructed.
When the water level is again OK, everything will
again be switched on with a small time delay.
You can connect the float plug to the female plug of
the control electronics. Pay attention to the recess
of the plug connection.
