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 Regulating volume of steam with
rotary knob on main unit
• 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
Regulating volume of steam with
handwheel on steam gun
•
If you are working with the standard accessories
you can regulate the volume of steam with the
handwheel on the steam gun. In this case the
rotary knob on the main unit is inoperative.
Note: If the handwheel is set for a small volume of
steam, it is quite possible that steam may still be
expelled from the nozzle for a short interval after
the steam switch has been released and until the
pressure in the steam hose has dissipated. You
can release the pressure more quickly by turning
the steam volume control to a higher setting.
2.5 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.
