5 | The 5 safety features of your Sicomatic® t-plus
The Sicomatic® t-plus that you have purchased is a
technologically advanced device. It has been designed
based on decades of experience in the manufacture and
development of pressure cookers.
1. Transparent operating valve
If the maximum pressure exceeds the selected cooking
level, the transparent operating valve opens and the
excess steam is released from the lid handle opening
in the front. Any excess pressure is also automatically
reduced. Please note that for functional and safety
reasons, only Sicomatic® H09F transparent operating
valves may be used.
2. Overpressure protection with integrated automatic
cooking feature
a) Automatic cooking function
The valve can be moved when not under pressure.
After parboiling the closed Sicomatic® t-plus, any
excess food-impairing atmospheric oxygen is auto-
matically discharged (automatic venting).
b) Function as an overpressure valve protection
The overpressure relief valve is not used during nor-
mal operation. It is only used when the transparent
operating valve fails and the pressure continues to
build up. Steam is then released from the discharge
opening on the lid shaft handle.
3. Safety slot
The “emergency outlet” on the rim of the lid is only used
as an additional safety mechanism if both the transparent
operating valve and the overpressure valve fail to work.
Once too much pressure builds up, the lid gasket is
pushed outwards as far as possible into the safety slot
so that steam can be released.
4. Residual pressure stop
The residual pressure stop integrated into the pressure
indicator rises even when there is a small amount of
pressure: The pressure indicator is visible. You can unlock
and open the cooker only once the pressure indicator
has completely retracted into the lid shaft handle. This
prevents accidental opening when under pressure.
5. Locking inhibitor
If the handles are not properly aligned, the lid will
not be sealed. Therefore, pressure cannot build up. In
addition, the red safety bolt in the lid handle prevents
pressure forming if the lid is not correctly closed and
releases steam.
