Putting into Operation
4. Putting into operation
4.1 Checking
4.1.1 Check the door and adjust if necessary
The door may have been twisted during transport. You should therefore check whether the
door closes properly and the seals are in the correct position. Adjust door if necessary (descrip-
tion on page 57 ).
4.1.2 Checking the temperature sensor
Due to strong vibrations during transport,
the temperature sensors could have moved
out of position in their holders in the
ceiling of the working chamber.
Before operating for the first time, check
the temperature sensor for its correct posi-
tioning and if necessary adjust its position
in the holder ( Fig. 9 ). Open the door to do
this (see page 22 )
4.2 Fill up and connect the water tank
Fill the water tank supplied with water and connect it with the
enclosed tube to the "H2O" connection on the rear of the
chamber ( Fig. 10 ).
Water specification
To generate steam, only either
► steam-distilled water (aqua dest) may be used
or
► demineralised/desalinated water (aqua dem) in accord-
ance with VDE 0510/DIN EN 50272, provided the regula-
tions are strictly maintained (conductivityof production
≤ 10 μS/cm). Battery water inaccorance with VDE 0510
can be obtained in all large chemist's, supermarkets, DIY
stores and wholesalers. VDE 0510/DIN EN 50272 must
be explicitly marked on the label.
Otherwise, limescale in the steam generators, steam piping
and tube pumps may impair the the functionality of the
appliance.
The water used must have a pH value of > 5 and < 7.
