Practical Hints - Tescoma PRESTO Serie Instrucciones De Uso

The pressure indicator will slip down automatically after the steam has been entirely released and the
pressure has dropped; it will release the lock against accidental opening and the pressure cooker can now
be opened.
If the pressure indicator remains in the upper position after releasing steam and the pressure cooker cannot
be opened, this means that there is still pressure in the vessel. Repeatedly push on the pressure regulator
using an oven mitten and wait until all steam escapes from the pressure cooker.
If the pressure indicator does not slip in automatically even after the steam has been released and the
pressure cooker still cannot be opened, place the pressure cooker into the sink and cool the lid with a small
amount of slowly running cold water until the pressure indicator slips in.
Then open the pressure cooker and thoroughly inspect and clean the operating valve and the safety valve
before further use.
NEVER COOL THE PRESSURE COOKER ABRUPTLY UNDER RUNNING WATER, DO NOT LET WATER RUN ONTO
PLASTIC PARTS AND DO NOT IMMERSE THE ENTIRE PRESSURE COOKER IN WATER.
SAFETY CUT-OUTS
Operating valve
The operating valve controls the high and low pressure, continuously releases excess steam and releases all
steam from the pressure cooker at the end of cooking.
Safety valve
The safety valve operates as a cut-out activated when the operating valve becomes clogged. Immediately
remove the pressure cooker from the heat source if steam ceases to escape from the operating valve and
starts to escape intensely from the safety valve during the cooking process. After the pressure cooker cools
down, open it and clean the operating valve.
Aperture in the rim of the lid
If the operating valve and the safety valve become clogged at once, the pressure in the pressure cooker
pushes the silicone seal through the aperture in the rim of the lid, which causes an immediate drop in
pressure and steam release.
Warning! When cooking with the pressure cooker, make sure that the aperture in the rim of
the lid is not directed towards individuals coming near the pressure cooker.
IF THE SILICONE SEAL IS PUSHED THROUGH THE APERTURE IN THE RIM OF THE LID, DO NOT REPAIR THE
PRESSURE COOKER YOURSELF; INSTEAD BRING IT IN FOR PROFESSIONAL SERVICING.
Lock against accidental opening
Prevents accidental opening of the pressure cooker until all steam has escaped from the vessel and pressure
drops entirely.

PRACTICAL HINTS

ALWAYS USE AN APPROPRIATE SIZE OF COOKING RANGE OR FLAME FOR COOKING.
The diameter of the cooking range must be identical or smaller than the diameter of the bottom of the
pressure cooker! Flame must never expand beyond the bottom of the pressure cooker. Use the dispenser
net or cooking range when cooking on gas.
Make use of the heat retaining properties of the three-layer sandwich bottom. Switch the heat off in
advance before the end of cooking. Thanks to the three-layer sandwich bottom, the accumulated heat
energy is transferred into the pressure cooker even after the heat has been switched off.
