4. Functionality and device composition
4.1 Principle of operation
The HygroMatik softener device makes use of the ion exchange
method for replacing magnesium and calcium as well as stron-
tium and barium by natrium, thus producing so called soft water.
The device works using the concurrent process and was
designed for normal salting.
The raw water fed to the softener must be iron- and maganine-
free. For use with raw water not complying to this prerequisite,
the WaterLine double softener device family WL-DP featuring a
special compatible resin filling may be used .
After the production of a set volume of soft water, regeneration
occurs on a regular base. For that purpose brine water is sucked
from the brine tank into the exchanger (pressure tank). Because
of the extremely high concentration of natrium in the brine the
hardness components bound are exchanged again with natrium.
The regeneration waste water is drained to a canal. On finishing
the regeneration cycle, the brine tank is filled-up again with
water to allow for the production of new brine.
Besides the volume based regeneration, forced regeneration is
carried out on a regular base to ensure proper hygienic condi-
tions. Otherwise, the softener may be prone to microbial con-
tamination if no water flow exists due to longer periods of non-
usage (e.g. during holiday periods) Pre-setting for forced regen-
eration is 3 days. This setting may be changed by the operator.
Since the WaterLine WL-S softener device features only one
pressure tank, the device is not available for soft water produc-
tion during regeneration. In contrast to this, the WaterLine sof-
tener devices WL-D and WL-DP are equipped with two pressure
tanks each, allowing for soft water production in the one tank
while - in parallel - the resin in the other tank is regenerated.
Because of this mechanism, these devices are designated as
„pendulum systems“. When the resin in the active pressure tank
is dead, the control valve switches to the other pressure tank
holding freshly regenerated resin of full capacity.
4.2 WL-S and WL-D/DP device composition
The systems are composed of a brine tank and one or two
exchangers. The resin-filled exchangers are pressure tanks
made from GRP. On top of the pressure tank (or one of the pres-
sure tanks in case of the WaterLine WL-D/DP systems) sits the
control valve. The control valve holds a displaceable piston for
supporting all of the steps of the ion exchanger and regeneration
processes and the microprocessor-based control logic.

Arranged in the brine tank is a stand pipe holding a riser pipe for
brine sucking. The bottom end of the riser pipe features a ball
valve that blocks sucking when the brine level has sunk accord-
ingly. The riser pipe top end is connected to the control valve
through a brine tube.
The control valve is connected to the house water installation
either directly or via a (optionally available) mounting block
through hoses for water inlet and water outlet (optionally avail-
able water connection set including titration kit may be used).
Hose connections make use of the provided BSPT adaptors
(BSPT = British Standard Pipe Thread).
Pendulum systems feature a single control valve with the

control valve on the other pressure tank via tubings for raw and
soft water.
The waste water hose is connected to a 3/4 inch elbow on the
control valve. Draining must feature an open outlet in order to
prevent microbiological contamination.
The control logic comprises a display for time-of-the-day presen-
tation as well as the preset and programmable parameters of the
ion changer process. Operating and programming is accom-
plished by use of the 5 keys designated „SET CLOCK“, „NEXT“,
„REGEN“as well as „Δ“ und „∇“ (up/down-arrows for increasing/
decreasing settings).

4.3 Use of optional chlorine cell
Periodical chlorination of the raw water feed to a softener device
is meaningful in order to fight microbiological contamination in
the exchangers and pipes by chemical means. For this purpose,
a chlorine cell may be inserted in the brine tube by use of a t-
piece connector that produces active chlorine. Any excessive
chlorin is washed out with the regeneration waste water. How to
use the chlorine cell is described in a chapter of its own.
4.4 Operating cycles
Normal operation mode of the WaterLine softener devices is
„softening“ . Alternating to this (in case of single systems) or in
parallel (with double systems), then in the currently not active
exchanger, „regenerating“ is carried out. The following operating
cycles can be distinguished in detail:
Normal operation
• Softening
Regeneration
• Backwash
• Brine and Slow wash
•Rinse
• Fill (brine tank)
4.4.1 Softening
This is the normal operation mode of the WaterLine softener
device. The control valve guides raw water into the pressure
tank filled with exchanger resin. Raw water flows top down
through the resin while the resin absorbes magnesium and cal-
cium ions, exchanging them with sodium ions. By this mecha-
nism, softened water is generated. The product water enters the
rise pipe in the pressure tank through the bottom nozzle and is
subsequently propagated to the control valve and, finally, to the
consumer through the product water pipe.
4.4.2 Regenerate
Since the exchange capacity of the resin is exhausted after a
certain volume of soft water produced, regeneration is required
on a regular time frame. For this purpose, NaCl brine is used
that is produced by dissolving salt tablets in the brine tank.
Regeneration point of time is determined by the control valve. To
enable this, „soft water capacity“ with respect to the Waterline
device capacity and local raw water hardness must be pro-
grammed into the the control valve logic. On reaching the
threshold set, automatic regeneration will result. The number of
regeneration occurences is only restricted by resin life time.

Page 15
Please note: The dimensioning of the WaterLine softener
device must be such that soft water demand does not exceed
the soft water capacity between any two regenerations.
The regeneration process is separated in the partial steps „back-
wash“, „brine/slow wash“, „rinse “ and „fill“.
4.4.2.1 Backwash
Under control valve regime raw water is fed bottom up through
the exchanger resin in the pressure tank, thus causing disaggre-
gation of the resin.
4.4.2.2 Brine and slow wash
In the brine tank, a 25 percent brine is prepared from raw water
and NaCl.
Please note: Building up the required brine concentration takes
6 hours of time minimum. Such, any two regenerations should
be separated by at least this time interval.
Brine is sucked up by the control valve injector and blended with
raw water to a 10 to 12 percent concentration, which is the opti-
mum concentration for the regeneration process. The diluted
brine is fed through the resin top down. Now ion exchange takes
place in the inverted direction as compared to softening, setting
free and draining calcium- and magnesium ions bonded by the
resin. Following brining, slow wash is carried out in the follow-
ing way: When no more brine is sucked by the injector, only raw
water flows through the resin bed in the pressure tank. Any brine
left in the pressure tank is swamped out by and by.
4.4.2.3 Rinse
Following slow wash, rinse is carried out with raw water guided
through the pressure tank top down at a rate of approx. 8 - 12 m/
h. After a flushed water volume corresponding to 3 to 4 times the
resin filling volume, proper soft water may again be produced.
4.4.2.4 Fill
The brine tank is filled-up automatically with a defined volume of
watert. After filling the regeneration prozess is terminated and
the control valve sets the WaterLine softener device back to nor-
mal operation.

4.4.2.5 Duration of the regeneration steps
Duration of the individual regeneration steps may be pro-
grammed by the operator (s. chapter 7 for details). Typical rec-
ommended settings are as such:
Backwash: 3 - 5 mins.
Brine/Slow wash: total time 45 mins. (brine is fully sucked-up in
approx. half of the time)
Rinse: 5 - 8 mins.
Fill: this „time“ is not set in minutes but is expressed by the salt
volume (in kg) needed per regeneration event. The individual
WaterLine softener models require the following settings:
*) Factory settings
In practise filling times lie betwwen1:30 mins. und 4:30 mins.
(depending on device capacity).

4.5 Brine
The capacity of a WaterLine softener device is not a constant but
is determined by the following factors:
• Raw water quality (drinking water quality required)
• Raw water hardness
• Raw water hardness variations (require regular checks)
• Raw water flow pressure
• Resin quality
• Resin volume
• Method of brining
These influencing variables must be considered when program-
ming the control valven. Below, particular attention is directed on
the method of brining.
Depending on the amount of NaCl consumed during regenera-
tion, full or partial brining is refered to. For a residual hardness of
soft water below 0.1 °dH, only full brining is adequate. Full brin-
ing requires the use of 220g of salt per liter of resin.
Please note: When working with zero hardness water, zinc-
coated pipes must not be used. Only pipes made from plastic or
stainless steel are adequate.
In case of a lower requirement concerning the residual hard-
ness, partial brining (i.e. 160g of salt per liter of resin) is allow-
able.
Please note: When using partial brining, a certain „slip of hard-
ness“ may occur, i.e. following a regeneration soft water hard-
ness may be increased by 2°dH (with respect to the set value)
for a certain amount of time.

damaging hazard to the brine tank.
• If required set-up a fundament
• A sewer junction must be in close proximity
• For safety reasons the installation location should feature
a floor gully. If no gully exists, a water stop may alterna-
tively be used.
5.4 Set-up of the WaterLine pendulum devices
WL-D/DP
The HygroMatik softener devices WL-D and W-DP are only par-
tially preconfigured when delivered. For transportation safety
reasons the second pressure tank is separatly packed. Before
operating the system, the tubing between the corresponding
connections on the control valve on top of the one pressure tank
and the connecting head on the other pressure tank must be put
in place. The connecting tube coupling nuts must only be
secured hand-tight.
5.5 Attaching the tubing for raw water and soft
water
5.5.1 Prerequisites for the correct connection of the
tubing on the softener device
• Raw water flow pressure must be 2.5 bar minimum. If not
the case, proper functioning of the WaterLine softener
device may be impaired by air cushions that may built up.
For monitoring flow pressure, it makes sense to integrate a
manometer into to the raw water pipe, if not already pre-
sent.
• Any installations (such as elbows etc.) upstream of the sof-
tener device that may reduce flow pressure are not allo-
wable
• Max. flow pressure must never exceed 7.0 bar. If a pres-
sure situation, pressure peaks or hydraulic shocks beyond
7.0 bar may be encountered, a pressure reducer must be
implemented upstream of the softener device.

• Raw water supply must always be secured by use of a
system separator according to EN DIN 1717
• A filter in the raw water pipe is indispensable in order to
prevent foreign matter to be washed into the control valve
possibly causing misfunctioning
• A rinsing valve just shortly upstream of the softener is
recommended. Rinsing the pipe after installing armatures
prevents debris such as pieces of kindling or impermeable
material to enter der WaterLine softener device
• On-site tubings must be supported by adequate means in
order to avoid tensions in the tubing system
• We recommend the use of pipes made from plastic or
stainles steel.. Zinc-plated pipes are not suitable for use
with zero hardness water.
5.5.2 Connecting the control valve to the house water
installation
» Use adequate hoses incl. flat gaskets to connect water
inlet and water outlet of the control valve to the house
water installation. Make sure to pay attention to the flow
direction arrows on the control valve indicating water
inlet and water outlet
» Check all connections for leakiness
For connecting, the optionally available „Water connection set
comprising 2 hoses and titration kit, art. no. B-5000103“ may be
used.
