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

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.
