Read the original instructions before using the unit for the first time and act in accordance with it. Keep the original instructions for future reference or for future owners.

• Only drinking water from a public water supply can be used to guarantee the water quality of the emerging water. The quality must at least correspond to the guidelines of the World Health Organization (WHO).

• If intervention in the drinking water network is necessary in order to install the unit, this must be done by a trained specialist who is authorised to do this according to the laws and regulations valid for the location. When installing the device, the applicable national regulations for interventions in the drinking water network must be observed. The work must be commissioned by the customer if required.

• For protection against water damage caused by a burst water hose, we recommend installing a shut-off device and an aqua stop (optionally available) in the water supply line.

• Maintenance work in the interior of the unit may only be carried out by the operator of the unit who has read these operating instructions.

• When using a CO₂ bottle, the locally applicable rules for marking the installation room must be observed.

• Do not clean the unit with a water jet.

• Plastic surfaces must not be cleaned with alcohol-based, aggressive or abrasive detergents. The surface cleaner CA 30 R (6.295-686.0) is recommended.

• After initial start-up, filter changes and long downtime periods, dispensed unchilled water may temporarily be milky in appearance. This is due to small air bubbles in the water and does not affect water quality.

• The unit is used to dispense both tempered and untempered water, with or without the addition of food-grade carbonic acid (CO₂), in self-service mode.

• Depending on the unit variant, the unit is equipped with different filters (Active-Pure filter or Hy-Protect filter).

• This unit is intended for use in domestic and similar applications, such as in staff kitchen areas in shops, offices and other work areas, in agriculture and by guests in hotels, motels and other accommodation, in catering and similar wholesale use.

• Do not set up or operate the unit in commercial kitchens.

• The unit must be set up in a frost-free room.

• Do not use or place the unit outdoors.

• Do not place, store or transport the unit horizontally.

Any type of improper use is prohibited.

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

From the water inlet, the water flows first through the filter (for a description of the filters, see Consumables). Depending on the button pressed, the water then flows through the cooling module, the CO₂-mixer (optional) or directly onward to the water dispenser.

If carbonated water is required (optional), carbon dioxide is also added to the water.

To ensure perfect hygiene, the entire water system must be chemically cleaned at regular intervals.

When replacing CO₂ bottles, the safety instructions of the gas supplier and any legal requirements must be observed.

• The CO₂ bottle must be equipped with the pressure reducer approved by KÄRCHER so that the carbonic acid content of the water can be adjusted.

• The carbon dioxide E 290 must comply with the purity requirements of Directive 96/77/EC (food quality) and be labelled in accordance with Article 7 of Directive 89/107/EEC.

• Before using a gas bottle, make sure that the correct type of gas has been provided. Reliable information about the type of gas is provided solely by the hazardous goods label that must be present on every gas bottle. The colour of the gas bottle does not always give clear information about the type of gas. A gas bottle of which there is any doubt about the contents or which is conspicuous in any other way (damage, exposure to fire, traces of mechanical processing) must not be used.

• The country-specific regulations must be observed.
