2. Directions for use

2.1 Important fundamental information

To achieve satisfactory results with a steam

cleaner, it is most important that the initial cleaning

stage is performed thoroughly. This means that

where detergents and other cleaning products

have been used for many years, the immediate

objective must be to strip away the layer that will

have built up. By using a steam cleaner, dirt is lifted

off, as described previously, and picked up by the

cloth. Depending upon the amount to be cleaned

off, the dirt will have been completely removed after

the cleaner has been applied 1 - 2 times. The result

is a floor surface that is free of streaks. The same

applies when cleaning windows. The steam

cleaner cannot remove large amounts of limescale

directly. A description of the procedure for

successfully removing these types of deposits is

contained in the section concerning the cleaning

of bathroom fittings.

2.2 Special notes on cleaning

Fabrics

Before steam-cleaning fabrics or textiles, we

recommend that first of all you carry out a test on

an inconspicuous part of the material. Apply plenty

of steam to the test area, and then allow the

material to dry out so that you can determine

whether any changes in colour or shape occur.

Coated or painted surfaces

When steam-cleaning kitchen cabinets or other

items of furniture, doors, parquet flooring, painted

or plastic-coated surfaces, please take into account

that waxes, furniture polish, plastic coatings or

paint may be dissolved or lifted off if they are

subjected to prolonged exposure to the steam jet.

Apply only small amounts of steam directly to these

types of surface, or clean them with a cloth to which

the steam has been applied first.

Glass surfaces / window panes

Glass surfaces may break if they are subjected to

uneven heating. Especially in the case of low

exterior temperatures, you should first of all spray

steam lightly over the whole glass surface in order

to even out any differences in temperature and to

avoid the build-up of tension on the surface of the

glass. Do not apply the steam jet directly to the

sealed parts of the window.

2.3 Steam volume control with rotary knob

• If you are working with the standard accessories

or the iron, you can control the volume of steam

by adjusting the rotary knob on the main unit.

2.4 VAPOHYDRO rotary control knob

• In washrooms or tiled areas, for example, you

can also flush the dirt away instead of wiping it

off with the cloth. This is achieved by varying the

moisture content of the steam by adjusting rotary

knob on the main unit. The greater the amount of

moisture in the steam, i.e. the more water there

is in the steam jet, the better the washing results

will be.

If you turn the rotary knob all the way round to

“+”, a jet of hot water is discharged from the

nozzle giving the greatest flushing effect.

• Use the VAPOHYDRO feature together with the

spot nozzle, for example, for cleaning the

bathroom.

• If you are working with cloths (floor nozzle, hand

nozzle), set the VAPOHYDRO rotary control

knob to “–”, so that the steam jet contains as little

moisture as possible. This improves the ability of

the steam to loosen and dissolve the dirt.

Note:

If you turn the VAPOHYDRO rotary control knob

to “+”, the boiler will empty more quickly.

2.5 Temperature indicator

• This indicator shows you whether you are

working within the proper temperature range

(green area).

2.6 Steam gun

• The steam can be used without accessories for

the following cleaning jobs:

– Deodorising clothing and removing creases

from garments;

– Dusting houseplants (maintain a distance of

approx. 30 cm);

– Damp dusting: apply small amount of steam to

surface and then wipe dry with a clean cloth.
