Read the original instructions before using the device 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 may be used to guarantee the water quality of the 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 device, this must be done by a trained expert who is authorised to do this according to the locally applicable laws and regulations. The work must be commissioned by the customer if required.

• To protect 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 inside the device may only be carried out by the operator of the device who has read these operating instructions.

• When using a CO₂bottle, the locally applicable rules for labelling the installation room must be observed.

• Do not clean the device using a water jet.

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

• The device is intended for dispensing chilled water with and without the addition of carbon dioxide (CO₂) in foodstuff quality in self-service mode.

• The device can be used in the following areas:

  • In the household and similar applications

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

  • In agriculture

  • In hotels, motels, bed and breakfasts and other accommodation facilities

  • In catering and similar wholesale use

• The device is equipped with a combination filter.

• The device must be installed in a frost-free room.

• The device may not be used or stored outdoors.

• Do not lay, store or transport the device.

Any type of improper use is prohibited.

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

When exchanging CO₂bottles, the safety instructions of the gas supplier and any legal provisions must be observed.

• The CO₂bottle must be equipped with the pressure regulator approved by KÄRCHER so that the carbon dioxide content of the water can be adjusted.

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

• Before using a gas bottle, you must ensure that the correct type of gas is provided. Only the dangerous goods sticker, which must be present on every gas bottle, provides reliable information about the type of gas. The colour of the gas bottle does not always give clear information on the type of gas. A gas cylinder, the content of which is in doubt or which is otherwise conspicuous (damage, exposure to fire, traces of mechanical processing) must not be used.

• Country-specific regulations must be observed.

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

1. Rotary control
2. Pressure reducer
3. Union nut
4. Main tap
5. Control pressure gauge
6. CO₂hose

1. Remove the protective cap from the new gas bottle.

3. Screw the pressure reducer onto the new gas bottle. Ensure that the sealing ring is seated properly.

4. Tighten the union nut hand-tight.

5. Fit the new CO₂bottle and fasten it with a tension belt.

6. Connect the CO₂hose to the pressure reducer.

7. Slowly open the main tap on the gas bottle.

8. Set the pressure reducer to 4 bar using the rotary regulator.

9. Close the main tap on the gas bottle.

10. Read off the displayed value on the control pressure gauge. The displayed value must remain constant for at least 5 minutes.

If there is a noticeable drop in pressure:

11. Eliminate the pressure drop.

    1. Check that the O-ring between the compressed gas tank and the pressure reducer is present and undamaged.

    2. If necessary, replace a defective O-ring.

    3. Check the pressure reducer for correct seating.

    4. Tighten the union nut more firmly.

    5. Check the hose coupling on the pressure reducer and the CO₂hose for visible damage.

If the pressure drop cannot be remedied by the measures mentioned, the pressure reducer is defective and must be replaced.

12. After passing the leak test, open the main tap.

13. Set the operating pressure on the pressure reducer using the rotary control. The default setting is 4 bar and can be readjusted if necessary.

14. After each renewal of the CO₂bottle, dispense one litre of "CO₂carbonated water" so that the CO₂mixer fills again.

When connecting a new or removing an empty CO₂cylinder the following steps are to be carried out.

---

1. Pressure regulator scale
2. Adjustment wheel
3. Pressure regulator
4. Screw connection

1. Pressure regulator scale
2. Adjustment wheel
3. Pressure regulator
4. Screw connection
5. CO₂hose
6. CO₂cylinder

1. Remove the cover from the CO₂cylinder.

4. Fasten the CO₂cylinder in a vertical position again.

5. Preset the pressure regulator to position "4".

6. After each renewal of the CO₂cylinder, dispense one litre of "CO₂carbonated water" so that the CO₂mixer fills again.

The water initially flows from the water inlet through the combination filter (for a filter description, see the Consumables chapter). Depending on the button pressed, the water then flows through the cooling module, or additionally via the CO₂mixer to the water dispenser. The entire water system must be chemically cleaned at regular intervals.
