Trademarks

QR-Code^® is a registered trademark of DENSO WAVE INCORPORATED.

• The device is used to dispense filtered drinking water.

• Filtered water is food and must be used within 1 to 2 days.

• The device retains residues from the line, heavy metals, chlorine, hormone and drug residues, microplastics, bacteria and viruses, as well as substances that impair taste and smell. All minerals remain.

• The input water must be drinking water according to WHO standards. The device is therefore not suitable for use with water of unknown origin, sea water or well water. It does not retain salts and minerals.

• The filter material is subjected to a special treatment with silver. A small amount of silver, which is harmless to health, can be released into the water. This corresponds to the WHO recommendations for drinking water.

• In the event of a request to boil tap water from an official body, e.g. the water supplier, the filter system must be taken out of operation. Once the boil order has been lifted, the filter cartridges must be renewed.

• The unit can be used in the following areas:

  • In the household and similar applications

  • In tea kitchens and break rooms

  • In staff kitchen areas of shops, offices and other work areas

  • In hotels, motels, bed and breakfasts and other accommodations

Any type of improper use is prohibited.

The operating personnel are liable for damage resulting from incorrect use.

The packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.

Old devices contain valuable, recyclable materials that should be recycled. Therefore, please dispose of old devices using suitable collection systems.

Current information on content materials can be found at: www.kaercher.de/REACH

When unpacking the device, check the contents of the box for completeness and for damage using the operating instructions. Please contact your dealer if any accessories are missing or in the event of any shipping damage.

• The water temperature and the water inlet pressure must correspond to the specified values, see chapter Technical data.

  ATTENTION

  For higher line pressures, always connect an external pressure reducer upstream!

• Depending on local regulations, an approved backflow preventer must be installed.

• Place the device on a flat, horizontal surface with the base facing downwards.

• The front cover and the stop valve must be freely accessible.

• The distance to heat-radiating appliances such as under-sink boilers or uninsulated hot water pipes must be at least 100 mm.

• Only connect the device with the lines provided.

• Do not use lines that are used.

• Do not bend the lines and do not subject them to tension, torsion or compression.

• Do not place any objects on the lines.

Connection diagram

1. Observe the connection diagram during installation:

   ---

   

1. Check the water inlet pressure at the pressure reducer of the building's drinking water installation. Under no circumstances may it exceed the maximum value specified in the Chapter Technical data. We recommend setting the water inlet pressure to 0.4 MPa (4 bar).

   If there is no pressure reducer in the drinking water installation of the building, a separate pressure reducer must be connected upstream of the device.

   If the value of the water inlet pressure cannot be determined in the drinking water installation of the building, a separate pressure reducer must be connected upstream of the device.

• Select the installation position so that the tap is accessible for installation from below and the opening of the outlet is above the sink.

  Allow sufficient space for connecting the 1/4″ line.

• The material thickness A of the sink / worktop must not exceed 24 mm. If the material thickness is higher, the worktop can be provided with a corresponding countersink from below. If in doubt, have the device installed by a person with professional knowledge.

• The upper and lower support surfaces must be flat and parallel, with a diameter B of at least 50 mm.
