2.6 Safety information for the specific system
WARNING: Risk of contamination of the drinking water in case of incorrect discharge of the
regeneration water
● Health risk due to contamination of the drinking water.
► When installing a discharge line for the regeneration water, do not connect any
devices directly to the drain outlet of the water softener. To install a drain, use
only the supplied black hose to allow the regeneration water to flow to the drain
connection.
WARNING: Danger of contamination of the drinking water due to prolonged periods of
inactivity of the system without automatic regeneration.
● Bacterial growth in the drinking water.
► Automatic regeneration with disinfection counteracts the bacterial growth. Do not
disconnect the water softener from the power and water supply when you are
absent for longer periods of time.
WARNING: Danger of drinking water contamination due to stagnation.
● Bacterial growth in the drinking water.
► According to VDI/DVGW 6023, filling the system with raw water prior to starting
the designated operation is prohibited.
Safety
11 | 74
BA_TD3-BM001en_014_Delta-p.docx
CAUTION: Insoluble impurities in the salt may cause malfunctions at the brine valve and at
the injector of the control valve.
● Dosage of salt according to requirements is not guaranteed.
► A defined salt quality is required for the reliable function of the water softener.
Only use salt tablets as per DIN EN 973 type A.
CAUTION: Blocking of reverse osmosis systems by blended raw water.
● The functionality of reverse osmosis systems is threatened.
► If the water softener is installed before a reverse osmosis system, the feed line to
the reverse osmosis system is not allowed to be configured as soft water with
blending.
CAUTION: Risk of uncontrolled water leakage during regeneration if there is a power
failure.
● Uncontrolled water leakage into the drain or brine tank.
► If there is a power failure, check the water softener and block the raw water
supply if necessary.

3.5 Functional description
3.5.1 Physical
The water softeners Delta-p are equipped with a central control valve for the three
exchangers and are controlled depending on the quantity.
Regeneration is triggered when the next exchanger to be regenerated is exhausted or 50%
of the next but one exchanger to be regenerated is exhausted.
The water softener regenerates with raw water.
3.5.2 Chemical
The exchanger contains ion exchanger resin in the form of small resin beads. Sodium ions
adhere to each resin bead. Hard water with a large proportion of calcium and magnesium
ions flows through the exchanger.
The ion exchanger resin absorbs calcium and magnesium ions from the water in exchange
for sodium ions. This reaction is called ion exchange. The calcium and magnesium ions are
retained in the exchanger. Soft water without calcium and magnesium ions, but containing
sodium ions, leaves the exchanger.
This process continues until no more sodium ions are available. The ion exchanger resin is
exhausted.
The exchange can be reversed if a large amount of sodium ions is added.
The exchanger is rinsed with brine, water containing salt.
By their sheer number, sodium ions displace calcium and magnesium ions on the ion
exchanger resin. This water containing calcium and magnesium ions is discharged to the
drain. The initial condition is restored.

WARNING: Danger of contaminated drinking water if the work is not carried out properly
● Risk of infectious diseases.
► Pay attention to hygiene when working on the installation.
► Store the packs of salt only in dry and clean rooms.

► Clean the packs before opening them.
► Fill the salt directly from the pack into the brine tank.
► Close the brine tank immediately after filling.
Proceed as follows to fill the brine tank:
1. Remove the cover from the brine tank.
2. Carefully fill the brine tank with raw water until the water level is about 30 mm
above the sieve bottom.
CAUTION: Insoluble impurities in the salt may cause malfunctions at the
brine valve and at the injector of the control valve.
● Dosage of salt according to requirements is not guaranteed then.
► A defined salt quality is required for the reliable function of the

1. Perform the 0 °dH (0 °f, 0 mmol/l) test. To do this, take water samples from the
water softener in operation:
a Open one of the customer's withdrawal points downstream of the water
softener. Without this measure, you will receive a mixture of waters from the
exchanger* and exchanger** at the sample valves.
b Take samples from each of the three bottle adapters on its sampling valve.
c In the case of systems with a blending valve, take an additional water sample at
the client's withdrawal point downstream of the system.
d Close the client's withdrawal point downstream of the water softener
2. Measure the hardness of the samples with the water test kit "total hardness".
3. Record your work in the start-up log and countersign it (refer to chapter 14).

service company beforehand.
The water softeners Delta-p are controlled by quantity. The operating parameters are
already stored in the GENO-IONO-matic

12 Other information
12.1 Explanation of terminology
Capacity
Describes the amount of fully softened water that the water
softener can produce in its entirety or in any part of it.
Regeneration water
After the regeneration, this water is saturated with calcium
ions and is flushed out of the system into the drain.
Raw water
Raw water is the untreated water before it passes through
the filter.
Stagnation
Inadequate water flow without pressure to force the water. In
dead-end pipes and in cross-connections, also in pipes that
are not being used such as during holidays.
Period of inactivity
Time in which a system filled with raw water is available
without power supply and without removal of water.
Drinking water
Drinking water is any water that is intended for use in the
domestic environment for drinking and all other food
preparation purposes, for personal hygiene and cleaning as
well as for cleaning objects that do not only temporarily
come into contact with foodstuffs or the human body.
Turbine water meter
A turbine (Woltmann) fitted in the system which transmits
pulses to a sensor by means of a magnet, thereby allowing
the flow rate through the system to be measured.
Fully softened water
Water with a residual hardness of 0 °dH.
Soft water
Soft water is the general term for softened water, and is also
referred to as softened or decalcified water.
12.2 Soft water with blending
CAUTION: Blocking of reverse osmosis systems by blended raw water.
● The functionality of osmosis systems is endangered.
► If the water softener is installed before a reverse osmosis system, the feed line to
the reverse osmosis system is not allowed to be configured as soft water with
blending.
For the soft water hardness, see the example calculation for the sodium content in the water
(refer to chapter 12.3).
Other information
55 | 74
BA_TD3-BM001en_014_Delta-p.docx
12.3 Sodium content in the water
When softening water by 1 °dH (0.18 mmol/l), the sodium content increases by approx.
8.2 mg/l. The German Drinking Water Ordinance specifies that the sodium content of
drinking water must not exceed 200 mg/l. Select a soft water hardness with a sodium content
less than 200 mg/l.
The local water suppliers will inform you about the sodium content of your raw water.
Sample calculation:
Raw water hardness: 28 °dH (50 °f)
Sodium content in the raw water: 10.5 mg/l
Admissible increase of the sodium content by softening:
● 200 mg/l - 10.5 mg/l = 189.5 mg/l
● 189.5 : 8.2 = 23 °dH (41 °f)
The raw water hardness is allowed to be reduced from 28 °dH (50 °f, 5 mmol/l) to 5 °dH (9 °f,
0.9 mmol/l).
