Initial Start-Up

ATTENTION
Device damage due to calcification
Always work with a decalcification cartridge.

1. Insert the decalcification cartridge into the water reservoir and press it firmly into place.
   Illustration D
   

Installation information
When steaming for the first time after removing and reinserting the decalcification cartridge, the steam jet may be weak or irregular, and individual drops of water may be expelled. The device requires a short running-in period in which the decalcification cartridge fills with water. The steam volume that is expelled increases constantly until the maximum steam volume has been reached after approx. 50 seconds.

Note
Please note that here it is set to steam stage 2 (tiles/ stone), since the running-in period will otherwise be extended.

Operation

Unwinding the power cable

Risk of electric shock
If the power cable is not completely unwound, the danger exists of you straining and damaging the power cable by overestimating the range of the cable.
Always completely unwind the power cable.

Important application instructions

Cleaning the floor areas

We recommend sweeping the floor or vacuum cleaning it before using the appliance. In this way the floor will be cleared of dirt and loose particles before the wet cleaning.

Cleaning coated or painted surfaces

ATTENTION
Damaged surfaces
Steam can loosen wax, furniture polish, plastic coatings or paint and edge band from edges.
Do not direct the steam at glued laminated edges as the edge band may loosen.
Do not use the device for cleaning unsealed wood or parquet floors.
Do not use the device for cleaning painted or plastic coated surfaces such as kitchen or living room furniture, doors or parquet.

How to use the Accessories

Floor nozzle

The floor nozzle is suitable for cleaning washable floor coverings, e.g. stone floors, tiles and PVC floors, as well as sealed wooden floors such as parquet and laminate.

ATTENTION
Damage due to steam effect
Heat and the effects of steam can lead to damage.
Check the heat resistance and steam effect on an inconspicuous area using a minimal volume of steam prior to use.
Steam clean sealed wooden floors using the correct, preset steam level, and do not remain in the same position on the floor for too long.

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

Beware of burns to your feet
The floor nozzle/floor cleaning cloth heats up during steaming.
Hot water may drip out when pulling off the floor cloth. Only operate or remove the floor nozzle/floor cleaning cloth with suitable footwear.
For fastening the floor cleaning cloth to the floor nozzle, please refer to chapter Installing the floor cleaning cloth

Microfibre floor cloth

The microfibre floor cloth is suitable for cleaning stone floors, tiles and PVC floors, and also sealed wooden floors such as parquet and laminate.

Abrasive floor cloth

The abrasive floor cloth is suitable for cleaning insensitive surfaces such as tiles or stone.

ATTENTION
Damage to floor coverings
The abrasive floor cloth can damage sensitive floor coverings and surfaces.
Do not use the abrasive floor cloth for cleaning wooden surfaces.
Do not use the abrasive cloth with the carpet glider.

Removing the floor cleaning cloth

1. Place one foot on the bottom corner of the floor cleaning cloth and lift the floor nozzle up.
   Illustration C

Note
Initially, the floor cleaning cloth's hook and loop fastener strip is very strong and cannot be removed from the floor nozzle easily. After the floor cleaning cloth has been used several times and washed, it is easier to remove from the floor nozzle and it has reached the optimum adhesion.

Removing the floor nozzle from the basic unit

ATTENTION
Material damage due to an unstable device

Replacing the decalcification cartridge

ATTENTION
Device damage and shortened service life
If the replacement intervals (indicator light) for the decalcification cartridge are not observed, there is a risk of device damage and the service life of the device may be shortened.
Observe the replacement intervals (indicator light).

Note
The anti-calcification effect of the decalcification cartridge is activated as soon as the reservoir is filled with water, and the device is put into operation. Lime in the water is absorbed by the granulate in the decalcification cartridge. Additional descaling is not required.

Note
The granulate in the decalcification cartridge may change colour after it comes into contact with water. This depends on the mineral content in the water.
This discolouration is harmless and does not have a negative effect on the device, the cleaning work or the functionality of the decalcification cartridge.

Indicator light at end of the run time

The indicator light shows you when the decalcification cartridge needs to be replaced.

• The indicator light flashes red 1 hour before the run time expires.
  Illustration R
  
• When the run time of the decalcification cartridge is exhausted, the indicator light flashes quickly. The pump switches off automatically (no water steam) to prevent damage to the device.

Inserting the decalcification cartridge

ATTENTION
Device damage
There is a risk of damage to the device if the used decalcification cartridge is re-used.
Work carefully in order to prevent mixing up the cartridges.

Installation information
When steaming for the first time after removing and reinserting the decalcification cartridge, the steam jet may be weak or irregular, and individual drops of water may be expelled. The device requires a short running-in period in which the decalcification cartridge fills with water. The steam volume that is expelled increases constantly until the maximum steam volume has been reached after approx. 50 seconds.

Note
Removing the water reservoir makes it easier to remove and install the decalcification cartridge.
