Note!
According to DIN EN 806-5 back flushing has
to be carried out at the filter with intervals
of 6 months at the latest, every 2 months an
inspection and twice a year a maintenance.
Warning!
For the drinking water hygiene reasons it
is not recommended to shorten the back-
flush procedure. The outflow volume at the
discharge valve should not be reduced so
that the full output can be used to back-
flush all particles being present in the filter
elements!
Maintenance
The back-flush indicator (A) with interval
indicator on the pressure difference display
should remind you of the next due main-
tenance in 6 months, if the month of the last
carried out back-flushing is set. The water
arisen at back-flushing can be drained away
by means of a catch container or through a
fixed waste water connection.
To carry out back-flushing press the red
indicating pin (the ball-point-pen principle)
so that the operating button (B) comes out.
If this knob is the sprung-up position, the
discharge valve can be opened by rotating
the operating button (B) 90° to the right.
Subsequently the water flows with the maxi
-
mum back-flushing volume from the outflow.
To carry out the back-flushing completely
the filter lower part (C) has to be rotated
additionally with two to three revolutions of
360° to the right or to the left. The discharge
valve (D) remains fully open.
Subsequently the discharge valve (D) has
to be closed again by turning the operating
button (B) 90° to the left, and the filter has
to be switched pressure-free to reset the red
clogging indicator. To do it block the filter
at the input (closing valve in flow direction
before the filter) and open at the discharge
valve (D) for a short time.
In this way the red indicator resets automati-
cally. The input side blocking device can be
opened again and the filter can be put into
operation.
To maintain the drinking water hygiene in
the filter element, Kemper recommends back
-
washing latest every 60 days.
