It is recommended to carry out maintenance works at
least once a year, in case of multi-family houses every
six months.
Proceed as follows to service the device:
a) Remove the cover on each side (fig. 1).
b) Should regeneration take place at this very
moment, wait until completed.
c) The operating piston rotates the driver (
1) (fig. 2),
which controls the small gear wheel. The position
indicator (
2) allows to read the driver's position.
The "Influx of salt" position (pos. 2) is reached
after two lifts. Afterwards, the operating piston
initiates another lift. The waste water quantity
used up to then amounts to approximately 4.5
litres.
d) The "backwash" position is reached after this lift
(pos. 3). The resin is flushed upwards. Waste
water roughly 3 - 4.5 litres
e) Two further lifts are carried out until the position
"Primary filtrate" (pos. 5) is reached. At this
stage, the resin is flushed downwards (waste
water 2.5 - 4 litres).
f) After two further lifts, the regeneration of the first
tank is completed. The driver now turns with two
lifts the right gear wheel to the position "Influx of
salt" (pos. 2) to regenerate the second tank
Afterwards, the system initiates another lift
(waste water quantity roughly 4.5 l).
g) The "backwash" position (pos. 3) is reached
after this lift. The resin is flushed upwards (waste
water approx. 3 - 4.5 l).
h) Two further lifts are carried out afterwards until
reaching the position "Primary filtrate" (pos. 5). At
this stage, the resin is flushed downwards (waste
water approx. 2.5 - 4 litres).
i)
After two further lifts, the regeneration of the
second tank is completed and the operating
position (pos. 1) is reached again.
j)
Should the measured values distinctly deviate
from the target values (refer to chapter "Main-
tenance report"), inform the after-sales service.
Please, always indicate the serial number, which
you will find on the upper side of the device's
connection flange (
3) (fig.2).
