Operation
If the pressure loss in the Softener system is
larger than approx. 0.8 bar, the overflow
valve integrated in the control head opens.
The open overflow valve reduces the pres-
sure loss by diverting the hard water around
the Softener system.
The pressure loss provision increases the
mixed water hardness downstream of the
hardness system for a short time die. During
regeneration the water drawn from the tap
flows through the overflow valve.
5.3
Salt fill
As the Softener functions automatically, you
only have to refill it with regeneration salt
from time to time.
At the latest when the “Top up salt” sticker
becomes visible in the salt container.
The salt stocks should not be allowed to re-
duce so much that the liquid level is above
the regenerating salt, otherwise it rises ex-
cessively when the salt is refilled. The liquid
level should be 10 - 12 cm above the floor of
the container.
If the container is not refilled in good time the
solid regenerating salt displaces the brine.
An unnecessarily large amount of brine is
drawn up during the next regeneration, the
intake procedure takes a correspondingly
longer time.
Our recommendation:
Broxo or Solvay
salt, either as a block, tablets or coarse
grains 7 - 15 mm.
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
If there is no more regenerating salt in the
container or if it is not refilled in good time,
the Softener switches to economy opera-
tion:
The brine stocks still available are primarily
used for disinfecting the ion exchange resin
and the softening effect is reduced.
In this way, the Softener remains in a hygi-
enically safe condition for weeks after the re-
generating salt shortage occurs.
5.4
Modifications / changes /
spare parts
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
Only original spare parts are to be used!
Independent modifications and changes are
prohibited for safety reasons! These can im-
pair the function of the Softener. The test
marks imprinted on the unit are only valid if
original spare parts are used.
5.4.1 Servicing/Repair
The unit must be serviced at least once a
year in accordance with the requirements of
DIN 1988. A half-yearly service is required
for jointly used systems.
We recommend you conclude a servicing
agreement.
Check the functions:
–
Remove the cover (
2
).
–
As long as regeneration is taking place
either the control lamp (
15
) is lit. As soon
as the regeneration is completed trigger
regeneration by
pressing on the regen-
eration trigger button (
18
).
–
The driving piston turns the driving
wheel (
23
), which in turn controls the
small gear wheel. Each stroke of the
driving piston is accompanied by the
lighting up of the LED (
14
). The position
of the driving wheel can be read off at the
position display (
11
). After two strokes
the salting position (Pos 2) is reached.
After approx. 3 minutes the drive exe-
cutes a stroke again. Wastewater quan-
tity up until then approx. 3.5 litres.
–
After this stroke the "Backwash" position
