Work Completion
Switch off the unit and pull the plug from the wall sock-
et.
Allow the unit and the remaining water to cool.

connection 7 upward in the clockwise direction and
the bayonet connector in the counter clockwise direc-
tion and pull out.
Empty the unit via the hose connection and allow to
dry. Open the tank cap to equalise pressure.
Ventilate the room thoroughly so that
the background can dry out.
Storage
The steam shield, hose and cable can be stored on the
unit in a space saving manner (see folded page).
Store the unit in a frost-free place.
Store the unit and accessories such that they are not
accessible to children.
Malfunctions
General
For malfunctions while working (e.g., no steam emerg-
es as a result of a kinked or pinched hose), always
switch off the unit first, pull the mains plug and allow to
cool. Then open the tank cap (see Filling or Refilling
with Water) and only then open the bayonet connec-
tor.
Never open the bayonet connector first! Danger of
scalding!

The unit switches off and on again at intervals
Cause:
The overheating protector is activated.
Corrective action:
– Switch off the unit and pull the mains plug.
Allow to cool.
– If the tank is empty (see minimum markering on
the level indicator 2), refill with water (see Filling or
Refilling with Water).
– If there is still water in the tank, the switching off
and on can have been caused by calcium depos-
its on the heating plate.
Decalcify the unit (see Maintenance and Clean-
ing).

Maintenance and Cleaning

Before any work on the machine itself, pull the
s
mains plug.
Always keep the machine clean so that it functions
s
properly and accurately.
Decalcifying
Never mix combustible, poisonous, caustic or
other liquids with the filling.
Decalcify the unit as necessary depending on the
hardness of the water and frequency of use.
Use commercially available decalcifying agent prefera-
bly with a citric acid basis. Observe the amount and in-
struction for use of the manufacturer of the decalcify-
ing agent!
Switch off the unit and pull the plug from the wall sock-
et.
Fill with the decalcifying agent. A half litre of solution is
adequate for decalcifying.
Remove the hose and switch on.
Allow the decalcifying solution to boil for approx. five
minutes.
Switch off the unit and pull the plug. Allow the solution
to act for approx. 10 minutes.
Allow the unit and the remaining solution to cool.
Empty the unit, rinse with clear water and allow the unit
to dry out.
In order to avoid accidents
– Never use the machine with a damaged cable.
– Never open the machine yourself.
