2 Safety
2.1 Safety measures
●Only use genuine spare parts for maintenance or repair.
●Risk of burns due to hot surfaces on lines and components
as well as due to escaping heating water. Let the product
cool down to at least 30 °C before carrying out any repair
and maintenance work. Risk of scalding due to escaping
hot heating water.
●Do not make any changes, alterations, extensions or pro-
gram changes on your product.
●Risk of slipping due to escaping heating water.
●Risk of tripping due to hoses on the floor as well as the
connection line. Lay the hoses and the connection line
away from traffic routes.
●Keep the premises locked against unauthorised access to
protect imperilled or untrained persons from residual risks.
2.1.1 Mechanical hazards
●You must never remove, bridge, or otherwise tamper with
safety equipment.
●Make sure that the product is set up or fastened in a way
that it cannot tip or fall over, and that the stability of the
product is guaranteed at all times.
●Potential risk of pinching and cuts on threaded connec-
tions. Use protective gloves when connecting the device.

Safety

2.1.2 Pressure-related hazards
●Components can be under pressure. There is a risk of inju-
ries and damage to property due to escaping water and un-
expected movement of components.
●Before starting repair and maintenance work, make sure
that all affected components are depressurised.
2.1.3 Electrical hazards
There is an immediate danger of fatal injury from electric shock
when touching live parts. Damage to the insulation or individual
components can be life-threatening.
●Check the mains cable for damage before each use.
●Only have qualified electricians carry out electrical work on
the device. If the device is used commercially, have it sub-
jected to an electrical safety inspection every year.
●In case of damage to live components, switch off the volt-
age supply immediately and arrange for repair.
●Switch off the supply voltage before working on electrical
system parts. Discharge residual voltage.
●Never bridge electrical fuses. Do not disable fuses. Use the
correct current ratings when replacing fuses.
●Keep moisture away from live parts. Moisture can cause
short-circuits.

2.2 Product-specific safety instructions
WARNING
Contaminated drinking water due to missing
system separation according to DIN EN 1717
●Infectious diseases due to bacterial growth in the
drinking water
►Make sure that the connection is secured by a system
separator during filling and make-up water feed of the
heating circuit with drinking water.
NOTE
Breakage of components in case of fixed instal-
lation
●If installed with mechanical stress, e.g. in case of fixed
piping, connections may break.
►Connect the device with flexible connection hoses only
(refer to chapter 3.4).
►Before start-up, check that the device is connected with-
out any mechanical stress.
Before the treatment, check the heating water for quality and
possible substances contained such as inhibitors.

Safety
13 | 80
BA_100093670000_en_065_desaliQ Inline-Regelmodul.docx
NOTE
Inhibitors contained in the heating circuit
●If inhibitors were added to the heating water, these will be
removed by the resin of the softening or mixed bed car-
tridge.
►Carry out the filter operation only.
►Check the concentration of the inhibitor during softening
and demineralisation operation.
►Re-establish the required inhibitor concentration, if nec-
essary.
Labels on the product
Hot surfaces/media
The affixed information and pictograms must be clearly legible.
They must not be removed, soiled or painted over.
►Obey all warnings and safety instructions.
►Immediately replace illegible or damaged symbols and
pictograms.
2.3 Conduct in emergencies
2.3.1 In case of escaping water
1. De-energise the device –pull the mains plug.
2. Close the shut-off valves at the inlet and outlet of the de-
vice.
3. Locate the leak.
4. Eliminate the cause of the water leak.

3 Product description
3.1 Intended use
●The desaliQ inline control module is designed for mobile as
well as temporary stationary use in heating circuits.
●The desaliQ inline control module is intended for the treat-
ment and filling of heating water during ongoing operation.
●For the duration of the treatment, the desaliQ inline control
module is integrated into the heating circuit in a bypass.
●The desaliQ inline control module is used in combination
with a mixed bed cartridge desaliQ:MB9 and the desaliQ in-
line filter module.
3.1.1 Foreseeable misuse
●The desaliQ inline control module must not be used for the
treatment of raw water that is to be used as drinking water.

3.3 Functional description
The function of the desaliQ inline control module is based on the
well-proven processes of filtration and softening or demineralisa-
tion.
The desaliQ inline control module is integrated into the filled heat-
ing or cooling circuit in the partial flow. Part of the circulation wa-
ter permanently flows through the desaliQ inline control module.
Prior draining or flushing of the heating circuit is not required.
The desaliQ inline control module measures the conductivity (LF),
the temperature and the flow rate. The remaining capacity of the
cartridge is calculated during softening.
The control unit integrated in the desaliQ inline control module
controls the water quality based on the parameters set and moni-
tors the treatment process.
The desaliQ inline control module works with the following auto-
matically monitored operating modes:
●Treatment
•Filtration
•Demineralisation
•Softening
●Filling
•Demineralisation
•Softening

Product description
18 | 80
BA_100093670000_en_065_desaliQ Inline-Regelmodul.docx
Filtration
In combination with the desaliQ inline filter module, undissolved
impurities such as rust and dirt particles are filtered from the heat-
ing water.
Demineralisation
In combination with the desaliQ resin bags, the heating water is
fully demineralised.
Softening
In combination with the softening cartridge decaliQ, the heating
water is softened according to the ion exchange principle.
Filling and make-up water feed of the heating circuit with
drinking water
When filling new systems, the circuit can be filled with drinking
water. The treatment of the circulation water by means of the de-
saliQ inline control module only takes place shortly before the
start-up of the heating circuit. Thus, optimum water quality is
achieved.
Make-up feed with drinking water when treating the heating water
is required due to a possible loss of water.
Monitoring mode
Upon reaching the programmed target values, the desaliQ inline
control module automatically switches to the monitoring mode.
Here, the desaliQ inline control module checks at regular intervals
whether the set target value for the conductivity in the system is
still maintained or whether it has changed.
