Note
Do not place the appliance into an upright
position while it is running. Otherwise, the
heating will turn off automatically after a
brief period and the indicator lamp "water
shortage" will illuminate in red.
 Switch the heating off by means of the
switch while the appliance is being
transported.
 Actuate the steam switch, steam will es-
cape. Always direct the steam gun at a
separate piece of cloth until the steam
is emitted evenly.
The heating of the steam cleaner is
turned on during operation of the appli-
ance (indicator lamp glows yellow) in
order to maintain the pressure in the
boiler at a constant level.
If the device is switched on without wa-
ter, initially, the indicator lamp "heating"
will glow yellow until the water shortage
thermostat switches the heating off. Af-
ter that, the indicator lamp "water short-
age" glows red.
steam quantity controller via rotary
knob on the appliance
 Regulate the steam volume during work
with standard accessories or with the
iron via the rotary knob on the appli-
ance.
Steam quantity controller via
handwheel on the steam gun
 Regulate the steam volume during work
with standard accessories via the hand-
wheel on the steam gun. The rotary
knob on the appliance becomes inac-
tive.
Note
If the handwheel is set to a small quantity of
steam, steam may continue to be emitted
after the steam switch has been released
until the pressure in the steam hose has
been reduced. This pressure can be re-
lieved even faster by briefly setting the
steam value regulation to a large volume.
VAPOHYDRO regulation with rotary
In wet areas, you can also wash away
the dirt instead of absorbing it with the
cloth. For this, set the moisture of the
steam to regulate via VAPOHYDRO
regulation by means of the rotary knob.
The higher the humidity of the steam,
i.e. the more water is contained in the
steam jet, the higher the rinsing effect.
If you turn the rotary knob toward "+"
steam quantity, a hot water jet is
emerged, and the highest rinsing effect
is achieved.
We recommend using the VAPOHY-
DRO in connection with the detail noz-
zle for cleaning the bathroom.
VAPOHYDRO regulation when working
with cloths (floor nozzle, hand nozzle)
with the rotary knob all the way to "–" in
order to have as little moisture in the
steam jet as possible. The dirt loosen-
ing power of the steam is improved this
way.
Note
If you turn the rotary knob for the VAPOHY-
DRO regulation to "+", the boiler is emptied
more quickly.
Refilling Water
Note
Once the water in the additional tank is
used up, there will be a signal emitted and
the indicator lamp for "water shortage in ad-
ditional tank" illuminates red.
 Fill the additional tank with a maximum
of 2 liters of fresh tap water using the fill-
ing funnel.
Once the indicator lamp "heating" has gone
out, the system is ready for use.
Note
If the pump does not produce any water in
spite of the full additional tank, the boiler
must be descaled.
