Place the properly closed cooker on a heat source commensurate with the
size of the pressure cooker base. See outside of cooker base for correct size.
(See section 13) Next turn the heat source up to full power.
As food begins to boil, firstly any atmospheric oxygen present in the
pressure cooker escapes through the valve. The valve cap will then pop up.
Now, the rising pressure indicator stem indicates the increasing pressure
inside the pressure cooker. Please observe: after a short while the first red
ring will become visible indicating that cooking level 1 has been reached.
The cooking time begins (see the cooking time table in section 15)
once the desired cooking level has been reached.
Meaning of the cooking levels:
To maintain the desired cooking level, the amount of heat applied to the
pressure cooker needs to be reduced accordingly.
A hissing sound accompanied by the escape of steam means that the
maximum operating pressure of 1.2 bar has been reached. Reduce the heat
and/or remove the pressure cooker from hob for a short time until the second
red ring on the pressure indicator is just visible.
Cooking level 1
Gentle cooking at a low cooking pressure (0.4 bar).
Cooking level 1 is reached as soon as the first red
ring on the pressure indicator is visible.
The first red ring is the only one that should always
remain visible during the entire cooking time.
Cooking level 2 is reached when both red rings on
the pressure indicator stem are visible. Both red
rings should always be visible during the entire
cooking time.
To maintain the desired cooking level, the amount
of heat applied to the pressure cooker needs to
be reduced accordingly.
