Maintenance

2.5.1

Filter unit

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 button 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 remains fully open.
Subsequently the discharge valve 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 clog-
ging 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

wise. You can read the chosen adjustment at
the indicator scale. After the required pressu-

resets automatically.
The input side blocking device can be opened
again and the filter can be put into operati-
on. To maintain the drinking water hygiene
in the filter element, Kemper recommends
backwashing latest every 60 days.
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!
