General notes

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.

Intended use

• The device is used to remove dirt with dry ice pellets that are accelerated by an air jet.
• The dry ice pellets are produced in the device. This requires liquid carbon dioxide from a dip tube bottle.
• The device may not be operated in a potentially explosive atmosphere.
• The minimum air exchange specified in the “Technical data” section must be observed at the operating location.
• The casing of the device may only be removed by KÄRCHER Customer Service for maintenance purposes.

CO2 quality

To ensure troublefree operation, the carbon dioxide used must at least comply with the following specifications:

• ● Carbon dioxide technical, class 2.5 or better
  ● Purity ≥ 99.5%
  ● Water content (H2O) ≤ 250 ppm
  ● NVOC (oil and fat) ≤ 2 ppm

Function

• Carbon dioxide snow is created via decompression of liquid carbon dioxide. The gaseous carbon dioxide that also arises is carried away from the workplace via the exhaust hose.
  The carbon dioxide snow is pressed into dry ice pellets in the device.
  Compressed air reaches the jet gun via a solenoid valve. The air pressure is controlled by an on-site pressure reducer. When the trigger of the jet gun is activated, the valve opens and the air jet emerges from the jet gun. Dry ice pellets are additionally dosed into the air jet via a dosing device.
  The dry ice pellets hit the surface to be cleaned and remove the dirt. The -79 °C cold dry ice pellets also create thermal stresses between the dirt and the object to be cleaned, which also contribute to the loosening of the dirt. In addition, the dry ice immediately turns into gaseous carbon dioxide when it hits the surface, thus taking up 700 times its volume. Dirt penetrated by the dry ice is blown away as a result.

Environmental protection

• The packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.
  Electrical and electronic devices contain valuable, recyclable materials and often components such as batteries, rechargeable batteries or oil, which – if handled or disposed of incorrectly

• can pose a potential danger to human health and the environment. However, these components are required for the correct operation of the device. Devices marked by this symbol are not allowed to be disposed of together with the household rubbish.

As the temperature rises, the effectiveness of pellet production decreases and a larger proportion of carbon dioxide is released in gaseous form via the exhaust hose. Store carbon dioxide bottles as cool as possible (below 31 °C) and protect them from heat, solar radiation and heat during operation.

1.  Push the device onto a level, stable surface.

2. Apply the parking brakes on both steering rollers.

3. Open both straps for the carbon dioxide bottle.

4. Place the carbon dioxide bottle on the storage space on the device.
   Note: If the carbon dioxide bottle is transported on a bottle cart, the front edge of the floor area on the transport cart can be placed on the surface of the  device. The bottle can then be moved from the trolley to the base by rotating it.

5. Place both straps around the carbon dioxide bottle, lock and tighten.

6.  Unscrew the protective cover from the carbon dioxide bottle.

   • ATTENTION
   • Malfunctions possible
   • Traces of fat interfere with the formation of dry ice snow in the device.
   • Check the connection nozzle and thread of the carbon dioxide bottle and the carbon dioxide hose and, if necessary, clean them before connecting to the device. Make sure that an undamaged seal is inserted between the bottle and the bottle connection.

7. For bottles with residual pressure valve, attach the ABS residual pressure valve (order number 2.574-006.0), available as an accessory, to the carbon dioxide bottle. Follow the separate instructions enclosed with the adapter.
   Open the CO2 bottle valve briefly (approx. 1 second) to remove any contamination.

8. Connect the bottle connection to the carbon dioxide filter on the carbon dioxide bottle.
   Make sure that a sealing ring bottle connection in perfect condition is inserted between the screw flange and the carbon dioxide bottle.
   Lightly tighten the narrow union nut of the screw flange with an opened wrench or ring spanner (e.g. 6.574-337.0). Hold the wide union nut with an open-end wrench to prevent the carbon dioxide hose from twisting.

ATTENTION
Do not put torsion (twist) on the carbon dioxide hose, otherwise it may be damaged.
