USER MANUAL IB 108 L2P Kärcher

quality To ensure trouble-free operation, the car- bon dioxide used must at least comply with the following specifications: ● Carbon dioxide technical, class 2.5 or better ● Purity ≥ 99.5% ● Water content (H

O) ≤ 250 ppm ● NVOC (oil and fat) ≤ 2 ppm Function Carbon dioxide snow is created via decom- pression of liquid carbon dioxide. The gas- eous carbon dioxide that also arises is carried away from the workplace via the ex- haust 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 con- trolled 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 addi- tionally 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 di- oxide when it hits the surface, thus taking up 700 times its volume. Dirt penetrated by the dry ice is blown away as a result.

ATTENTION ● Indication of a potentially dangerous situ- ation that may lead to damage to proper- ty. Symbols on the unit Danger from flying dry ice pellets. Do not point the jet gun at people. Remove third par- ties from the operating loca- tion and keep them away (e.g. via barriers) during operation. Do not touch the nozzle or the dry ice jet during operation. Risk of suffocation from carbon dioxide. During operation, the car- bon dioxide content of the air at the workplace increas- es. Make sure there is sufficient air exchange at the workplace. Lay the exhaust hose outdoors, for exam- ple, so that nobody is endangered by car- bon dioxide. Note: Carbon dioxide is heavier than air. Make sure that carbon dioxide does sink to lower-lying areas, for example by flowing from the outside into a basement below the workshop (flows). For longer jet work (longer than 10 minutes per day) and especially in small rooms (less than 300 m³), we recommend wearing a carbon dioxide warning device. Signs of high levels of carbon dioxide: 3 p. 5
• %: Headache, high breathing rate. 7 %: Headache, nausea, possibly un- consciousness. If these symptoms occur, switch off the de- vice immediately and get some fresh air. Before continuing work, improve ventilation or use a breathing apparatus. Carbon dioxide is heavier than air and col- lects in confined spaces, lower-lying spac- es or in closed containers. Ensure adequate ventilation at the workplace. Observe the safety data sheet from the car- bon dioxide supplier. Risk of injury, risk of damage from electrostatic charging. The cleaning object can be- come electrostatically charged during the cleaning process. Ground the object to be cleaned and keep it grounded it until the cleaning process is complete. Risk of injury from electric shock. Do not open the device. Work on the device may only be performed by KÄRCHER Cus- tomer Service. Risk of injury from cold burns. Dry ice has a temperature of - 79 °C. Do not touch the dry ice or cold parts of the unit. Risk of injury from carbon di- oxide bottle falling over, Dan- ger of suffocation due to carbon dioxide Attach the carbon dioxide bottle securely. Risk of injury from flying dry ice pellets and dirt particles. Wear safety goggles. Danger of hearing damage. Wear hearing protection. Risk of injury from flying dry ice pellets and dirt particles. Wear protective gloves accord- ing to EN 511. Risk of injury from flying dry ice pellets and dirt particles. Wear long-sleeved protective clothing. Caution! Permanent malfunc- tions possible. Traces of fat or oil interfere with the formation of dry ice snow in the device. Do not use grease, oil or other lubricants on the connection nozzle or on the thread of the carbon dioxide bottle or the carbon di- oxide hose. General safety instructions DANGER Risk of injury The device may start up unexpectedly. Unplug the mains plug from the power socket before working on the device. Risk of injury Dry ice and cold device parts can cause cold burns on contact with the skin. Wear cold protection clothing or allow the device to warm up before working on the device. Never put dry ice in your mouth. Risk of injury The dry ice jet can be dangerous if used im- properly. Do not direct the dry ice jet at persons, live electrical equipment or at the device itself. Do not aim the dry ice jet at yourself or oth- ers, e.g. to clean clothes or shoes. Risk of injury Light objects can be blasted away by the dry ice jet. Fix light objects in place before starting cleaning. Risk of asphyxiation Increased concentration of carbon dioxide in the air you breathe can lead to death from suffocation. Make sure that no exhaust gases are emit- ted close to air vents. Provide adequate ventilation in the work- place and ensure that the exhaust gases are properly discharged. 몇 WARNING Risk of injury The recoil force of the jet gun can throw you off balance. Find a safe place to stand and hold the jet gun firmly before you pull the trigger. Risk of injury Dry ice pellets and dirt particles can hit and injure people. Do not use the device when other people are within range unless they are wearing protective clothing. Do not use the device if a power cable or important parts of the device are damaged, e.g. safety devices, abrasive hose, jet gun. Safety instructions for gas bottles DANGER Risk of bursting, risk of suffocation Gas bottles can burst if they become too hot or if they are mechanically damaged. Leaking carbon dioxide can cause death by suffocation. Protect gas bottles from excessive heat, fire, dangerous corrosion, mechanical damage and unauthorized access. Store gas bottles so that no escape routes are restricted. Do not store gas bottles in underground rooms, on and at stairs, in hallways, corri- dors and garages. Do not store gas bottles together with flam- mable materials. Store gas bottles upright. Secure gas bottles against tipping over or falling. Close the bottle valve before transporting gas bottles. Transport gas bottles with a gas bottle cart or a vehicle and secure the bottles against falling. Pull on the protective cover before lifting the gas bottle to check that the protective cover is securely in place. Secure the gas bottle at the point of use against falling over. Do not open the bottle valve to check the pressure. Open and close the bottle valve only by hand without the aid of tools. Check the bottle valve/device connection for leaks. Close the bottle valve during work breaks and at the end of work to prevent uncon- trolled gas escaping. Only empty gas bottles so far that a small residual pressure remains in the bottle in order to prevent foreign matter from enter- ing. When the gas bottle has been emptied to the residual pressure, first close the bottleEnglish 13 valve before unscrewing the extraction de- vice. The gas bottle still has considerable residual pressure. Before returning it, screw the locking nut and the protective cover onto the gas bottle. If the gas escapes uncontrolled, close the bottle valve. If the gas emission cannot be stopped, take the bottle outside or leave the room, lock the access and only enter and ventilate the room if a concentration meas- urement rules out a danger.

2. Connect a compressed air hose to the

compressed air connection on the de- vice.

3. Slowly open the on-site compressed air

stop valve. Connecting the carbon dioxide bottle Requirements for the CO

bottle with dip tube for withdrawing liquid CO

bottles with a dip tube (also called a riser) are usually marked with a large "T" on the bottle or the back of the bottle. In some cases, the dip tube is additionally symbolised by a vertical colour line on the bottle. ● The CO

quality must correspond to the specifications in the chapter "Intended use". ATTENTION Malfunctions A residual pressure valve or check valve connected to the CO

bottle prevents ex- traction of the required CO

amount. If a CO2 bottle with residual pressure valve is used, the ABS residual pressure valve (order number 2.574-006.0), available as an accessory, must be installed between the bottle and the unit. Illustration E 1 CO

bottle without residual pressure valve 2 CO

bottle with residual pressure valve 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 sur-

2. Apply the parking brakes on both steer-

3. Open both straps for the carbon dioxide

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 di-

oxide 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 di- oxide hose and, if necessary, clean them before connecting to the device. Make sure that an undamaged seal is in- serted 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.

8. Connect the bottle connection to the car-

bon dioxide filter on the carbon dioxide bottle. Make sure that a sealing ring bottle con- nection in perfect condition is inserted between the screw flange and the car- bon dioxide bottle.

9. Lightly tighten the narrow union nut of

the screw flange with an open-end 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 di- oxide hose, otherwise it may be damaged. Establishing the voltage supply DANGER Risk of injury from electric shock The power socket used must be installed by an electrician and comply with IEC 60364-1. The device may only be connected to a voltage supply with protective earth. The power socket used must be easily ac- cessible and at a height of between 0.6 m and 1.9 m above the floor. The power socket used must be within sight of the operator. The device must be protected by an error current circuit breaker, 30 mA. Check the mains connection of the device for damage before each use. Do not oper- ate the device with a damaged power ca- ble. Have a damaged cable replaced by a qualified electrician. The extension cable must ensure IPX4 pro- tection and the cable design must at least comply with H 07 RN-F 3G1.5. Unsuitable extension cables can be dan- gerous. If an extension cable is used, it must be suitable for outdoor use and the connection must be dry and above the ground. It is recommended to use a cable drum that holds the socket at least 60 mm above the floor.

1. Plug the mains plug into the socket.

When working on the carbon dioxide filter, be careful not to get any dirt into the device. ATTENTION Malfunctions Malfunctions due to contamination. After each loosening or unscrewing of the screw plug, the carbon dioxide filter and the copper seal must be replaced. If this is not done, particles can become detached from the carbon dioxide filter and lead to mal- functions. Note The carbon dioxide filter is backwashed and cleaned as soon as the pressurised cylinder connection is disconnected from the carbon dioxide cylinder. Regular re- placement of the carbon dioxide filter is therefore not necessary.

1. Close the stop valve on the carbon diox-

2. Operate the unit at the highest level for

about 1 minute to depressurise the car- bon dioxide hose.

3. Unscrew the screw flange on the carbon

4. Carefully unscrew the screw plug from

the screw flange. Let the hose flange hang down to prevent dirt from entering the carbon dioxide hose. Illustration P 1 Screw flange 2 Carbon dioxide filter 3 Copper sealing ring 4 Screw plug

Technical data The pellet production fault in- dicator lights up Allow the device to thaw out. Check the carbon dioxide filter and change it if necessary. Then per- form a reset. If the malfunction occurs repeatedly, replace the carbon dioxide bottle. The pellet metering fault indi- cator lights up Switch the device off and back on again. If the fault indicator remains lit, contact the customer service. The pellet metering fault indi- cator flashes Allow the metering motor to cool down. Position the device so that air can flow into the device from below. Contact Customer Service if necessary. The voltage supply indicator light does not light up Plug the mains plug into the socket. Check the on-site voltage supply. The compressed air indicator light does not light up Connect a compressed air hose to the device. Open the stop valve in the on-site compressed air supply. The device does not work Check the indicator lights and fault indicators. Perform a reset. Poor cleaning performance Turn the program switch to a higher level. Increase the jet pressure. Check the filling level of the carbon dioxide bottle. Do not use a heated carbon dioxide bottle. Protect the carbon dioxide bottle from heat radiation. The effectiveness of the pellet production drops sharply if the temperature of the carbon dioxide is above 31 °C. Allow the abrasive hose and the jet gun to thaw to clear any blockages. Then increase the jet pres- sure. Pellet dosage too low Turn the program switch to a higher level. Replace the carbon dioxide filter between the carbon dioxide bottle and the device. Recurring interruptions in the dry ice stream Turn the programme switch to a lower level or increase the jet pressure. If the jet nozzle is clogged: a Immediately close the carbon dioxide bottle. b Allow the unit to thaw for 30 minutes. c Increase the jet pressure. d Start the appliance with the carbon dioxide bottle closed to remove pellet residues.
