Safety devices

Safety devices protect the user and may not be disabled or functionally circumvented.

Pressure regulator
The pressure regulator keeps the boiler pressure as constant as possible during operation. The heating is switched off when the maximum operating pressure in the boiler has been reached and switched on again when the pressure in the boiler drops due to steam removal.

Water shortage thermostat
The heating temperature rises when the water in the boiler runs out. The water shortage thermostat switches the heating off and the “Steam boiler water shortage” indicator light lights up red. The heating cannot be switched on again until the boiler has cooled down or is refilled.

Safety thermostat

• If the water shortage thermostat fails and the device overheats, the safety thermostat switches the device off.
• Before resetting of the safety thermostat, contact the responsible KÄRCHER Customer Service.

Safety lock

• The safety lock seals the steam boiler against the steam pressure present. If the pressure regulator is defective and overpressure occurs in the steam boiler, an pressure relief valve opens in the safety lock and steam escapes through the lock.
• Before re-commissioning the device, contact the responsible KÄRCHER Customer Service.

Cleaning methods

Freshening textiles
Always check the compatibility of the textiles at a concealed point before using the device on textiles: First steam the textile, allow it to dry and then check it for any change in colour or shape.

Cleaning of coated or painted surfaces
Wax, furniture polish, plastic coatings or paint can come off or stains may occur when cleaning painted or plastic coated surfaces such as e.g. kitchen and living room furniture, doors, parquet or linoleum. To clean these surfaces, steam a cloth briefly and wipe it over the surfaces.

Glass cleaner
Preheat the window pane in seasons with particularly low temperatures. To do this, lightly steam the entire glass surface at a distance of approx. 50 cm. This avoids tension on the surface that can lead to glass breakage

Initial startup

Installing accessories

1. Open the cover of the device socket and plug the steam connector tightly into the device. The lugs of the plug must latch on the cover of the device socket.
2. Connect the accessory (floor nozzle, manual nozzle or spotlight nozzle) to the steam gun. Push the parts together until the locking button on the steam gun engages.
3. Use extension tubes if necessary. Push the parts together until the respective locking button engages.
4. Press the locking button to separate the accessories.

Filling water
Note
Distilled water (no limescale formation) can be used but this leads to faster wear of the boiler and is thus not recommended.

1. Check that the safety lock is seated tightly.

2. Unscrew the reservoir cap from the fresh water tank.

3. Insert the filler funnel into the fresh water tank and turn it to latch it in place.

4. Pour approximately 2 litres of tap water into the fresh water tank.
   Do not use detergents!

5. Unlock and remove the filler funnel.

6. Screw the reservoir cap onto the fresh water tank.

Operation

Temperature indicator
The temperature indicator shows if the correct temperature range is being used (working temperature range).

Switching on the device

• The heating switches on periodically during use (indicator light lights up yellow) to maintain the pressure in the boiler.
• If the device is switched on without water, the “Heating” indicator light lights up yellow until the water shortage thermostat switches the heating off. The “Steam boiler water shortage” indicator light then lights up red.

1. Plug the mains plug into a mains socket.

2. Switch on the unit with the fresh water tank pump switch and the heating switch. The indicator lights light up.
   Note
   The full heating capacity is only available if the steam connector is connected to the device when it is heating up. The system is ready for operation when the “Heating” indicator light goes out.
   Note
   Do not stand the device upright when it is switched on. Otherwise the heating switches off automatically after a short time and the “Steam boiler water shortage” indicator light lights up red.

3. Switch off the heating at the switch when transporting the device.

4. Press the steam switch, steam comes out. Always point the steam gun at a cloth first until the steam flows out evenly.

Steam quantity regulation
Note
If the steam quantity regulation is set to a small quantity, steam may still escape briefly after releasing the steam switch until the pressure in the steam hose is released. This pressure can also be released more quickly by setting the steam quantity regulation to large quantity for a short time.

1. Adjust the steam quantity using the rotary knob on the device when working with standard accessories.

VAPOHYDRO regulation with rotary knob

• In wet areas, the dirt can also be washed away instead of being picked up with the cloth. For this, adjust the moisture content of the steam using the VAPOHYDRO regulation rotary knob. The higher the moisture content of the steam, i.e. the steam jet contains more water, the greater the flushing effect. The rinsing effect is greatest when the rotary knob is turned anticlockwise to the largest amount (+) so that a hot water jet is emitted.
• We recommend using the VAPOHYDRO in conjunction with the spotlight nozzle for e.g. cleaning in the bathroom.
• Turn the rotary knob of the VAPOHYDRO regulation clockwise to the smallest quantity (-) when working with cloths (floor nozzle, manual nozzle) to provide as little moisture as possible in the steam jet. This improves the dirt-dissolving power of the steam.

Note
The boiler empties more quickly when the rotary knob of the VAPOHYDRO regulation is turned anticlockwise to the largest quantity (+).

Refilling water
Note
An acoustic signal sounds and the “fresh water tank water shortage” indicator light lights up red when the water in the fresh water tank is used up.
Note
If the pump does not deliver water despite a full fresh water tank, the boiler must be descaled.

1. Fill a maximum off 2 litres of tap water into the fresh water tank using the filler funnel. The “Fresh water tank water shortage” indicator light goes out. The system is ready for operation when the “Heating” indicator light goes out.

Disconnecting accessories
DANGER
Danger from hot water
Risk of scalding Never disconnect accessories while steam is being released as hot water may drip out. Allow the device to cool down first.

Switching off the device
Note
The residual water can remain in the device.

1. Switch off the device at the switch.
2. Fold down the cover of the device socket and pull the steam connector out of the device.
3. Pull the mains plug out of the socket.

Storing the device
Note
Always let the brushes cool down to prevent deformation of the bristles.

1. Place the manual nozzle, spotlight nozzles and small parts in the accessory compartment.
2. Wrap the mains cable around the cable hooks when the unit is stationary.
3. Insert the extension tubes individually into the recesses on the base of the unit.

Using accessories

Note
Detergent residues or care emulsions on the surface to be cleaned can cause streaks during steam cleaning, but these disappear after repeated use.

Steam gun
Application examples for the steam gun without accessories:

• Eliminate odours and creases from hanging clothes by steaming them at a distance of 10-20 cm.
• Removing dust from plants. Maintain a distance of 20-40 cm.
• Damp dusting by briefly steaming a cloth and wiping it over furniture.

Spotlight nozzle

• The cleaning effect increases the closer the nozzle is held to the dirty area, since the temperature and pressure of the steam are greatest at the emission point.
• The spotlight nozzle with the various attachments is suitable for cleaning hard-to-reach areas, such as e.g. corners, joints, etc., blinds, central heating, toilets, stainless steel, windows, mirrors, fittings, coated and enamelled surfaces and for loosening stains.
• The power nozzle increases the speed of the emitted steam. It is therefore well suited for cleaning particularly stubborn dirt, blowing out corners, joints, etc.

Note
The round brush is not suitable for cleaning sensitive surfaces.

Floor nozzle
Floor nozzle with bristles

• For abrasive cleaning of stubborn dirt.
• Suitable for all washable wall and floor coverings, e.g. stone floors, tiles and PVC floors. Work slowly on surfaces that are heavily soiled so that the steam has longer to take effect.

Floor nozzle with slats

• For hygienic cleaning of smooth surfaces, as the surface temperature is higher.
• For a hygienic cleaning result, steam directly over the hard surface at a working speed of max. 30 cm / second. In addition, set the VAPOHYDRO to the minimum level and steam pressure to the maximum level.

Using the floor cleaning cloth
Turn and change the floor cleaning cloth regularly to improve dirt absorption.

1. Fasten the floor cleaning cloth to the floor nozzle. To do this, fold the floor cleaning cloth lengthways and place the floor nozzle on it, open the retaining clips, place the ends of the cloth in the openings and stretch tightly, close the retaining clips.

CAUTION
Danger from retaining clips
Risk of crushing
Do not put your fingers between the retaining clips

Manual nozzle
Suitable for small washable surfaces, shower cubicles, mirrors or furniture fabrics.

1. Pull the terry cloth cover over the manual nozzle.

Window nozzle (special accessory)
Order number 4.130-115.0

1. Steam the glass surface evenly at a distance of approx. 20 cm.
2. Switch off the steam supply.
3. Pull off the glass surface in strips from top to bottom with the squeegee.
4. Wipe the squeegee and the lower edge of the window dry after each run.

Wallpaper remover (special accessory)
Order number 2.863-076.0 The wallpaper remover can be used for removing wallpaper with the steam cleaner.
Note
In the case of multiple-painted wood-chip wallpaper, the steam may not be able to penetrate the wallpaper. In this case, preliminary work with a pin roller is recommended.

1. Apply the wallpaper remover to the edge of a wallpaper strip over the entire surface and allow steam to act until the wallpaper is soaked through (approx. 10 seconds).
2. Move the wallpaper remover without switching it off. Lift the dissolved piece of wallpaper with a spatula and peel it off the wall.
