2 Safety
2.1 Safety measures
●Only operate your product if all components are installed properly.
●Obey the local regulations on drinking water protection, accident prevention and
occupational safety.
●Do not make any changes, alterations, extensions or program changes on your
product.
●Only use genuine spare parts for maintenance or repair.
●Keep the premises locked against unauthorised access to protect imperilled or
untrained persons from residual risks.
●Comply with the maintenance intervals (refer to chapter 8.2). Failure to comply can
result in the microbiological contamination of your drinking water system.
2.1.1 Mechanical hazards
●You must never remove, bridge, or otherwise tamper with safety equipment.
●For all work on the system that cannot be carried out from the ground, use stable,
safe and self-standing access aids (e.g. stepladders).
●Make sure that the system is set up in a way that it cannot tip over and that the
stability of the system is guaranteed at all times.
2.1.2 Pressure-related hazards
●Components can be under pressure. There is a risk of injuries and damage to
property due to escaping water and unexpected movement of components. Check
the system’s pressure lines for leaks at regular intervals.
●Before starting any 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.
●Only have qualified electricians carry out electrical work on the system.
●In case of damage to live components, switch off the voltage supply immediately
and arrange for repair.
●Switch off the supply voltage before working on electrical system parts. Discharge
residual voltage.

Safety

3.1.3 Application limits
Observe the country-specific stipulations for soft water hardness in the drinking water
sector.
●The water to be softened must be free of iron and manganese.

3.4 Functional description
3.4.1 Process
The water softeners GENO-mat duo WE-X/WEW-X work according to the ion exchange
principle. The exchange of calcium and magnesium ions for sodium ions causes the water to
become soft.
3.4.2 Function
The water softeners feature a control valve for both exchangers and are volume-controlled.
The regeneration is triggered when the pre-set water volume in an exchanger has been
softened. The water softeners regenerate with soft water.
3.5 Permissible regenerant
The water softeners must only be operated with salt tablets according to DIN EN 973 type A
as regenerant.
►Obey the requirements regarding storage and handling of the regenerant
(refer to chapter 4.3).

3.6 Application in the drinking water sector
Country-specific requirements
●Czech Republic:
According to the czech decree no. 252/2004 softened drinking water should not
fall below a soft water hardness of 2 mmol/l (approx. 11°dH)
●Austria:
In Austria, softened drinking water must have a soft water hardness of at least
8.4 °dH.
3.6.2 Blending unit
●In case of GENO-mat duo WE-X systems 50/130/230 with economy salting, the
connection block with blending valve is supplied as standard.
●For GENO-mat duo WE-X systems 65/150/300 with full salting, this blending unit is
available as an accessory.
When softening drinking water, the specifications of the German Drinking Water Ordinance
must be adhered to.
●Residual hardness 3 °dH –8 °dH
●Max. sodium content 200 mg/l
To achieve this, a blending valve to add inlet water is required (refer to chapter 6.3.1).
