Technical Training GENERAL PRINCIPLE 1.1. - General principle An extractable water tank holding one litre is placed in a position on the right hand side of the appliance. The water it contains is propelled intermittently into the cavity by a hydraulic pump. It comes through a duct and changes into steam on reaching the heat produced by the generator.
Technical Training STUDY OF COOKING 1.2. - Study of cooking A cooking includes four different stages: Ø Air saturation with steam - rise in temperature (step 0 and step 1) This first phase lasts ten minutes. The thermoelectric activator is on and closes the flap valve. The generator heats up for two minutes before the pump is activated.
Technical Training STUDY OF COOKING 1.2.1. - The regulation generator The N.T.C sensor keeps the microprocessor inform of the generator temperature. The microprocessor controls the power supply to generator. Generator sensor N.T.C STEP T°C max T°C min STEP 0 121°C 119°C STEP 1 119°C...

Technical Training STUDY OF COOKING 1.2.4. - Opening the door during the cooking When the door is opened during the cooking, there is a reduction in temperature and a loss of steam. For the best cooking quality, it is essential to make up for these deficiencies. As soon as the door is opened, a micro contact opens, inform the electronic board of the door opening.
Technical Training DIFFERENT COMPONENTS The different components Designation Function Characteristics Tank The tank must 1 liter of water • Be filled up to maximum level with water before every cooking session. The noise that can be heard if you • shake the tank when is empty comes Be emptied after every cooking from the water level detector.
