2.3.2. Solid substances Solid substances are e.g. sand or residues from the piping; to avoid these materials to deposit: insert a filter. 2.3.3. Dissolved substances Dissolved substances are gases and salts. Gases If the gases are nitrogen, oxygen and carbon dioxide it does not create any problems. If on the contrary the carbon dioxide is dissolved in an aggressive form as carbonic acid, the following measures (filter, degas) are to be foreseen to avoid corrosion.
2.6. General information - Do not block the vapour escape. - Do not block or cover the safety device (steam release safety valve). - The units are designed for unattended operation. 2.7. Procedure in case of malfunction In case of malfunction disconnect the unit immediately and call for the after-sales-service. Any servicing or reparation of malfunction is to be carried out by authorized qualified technicians only. 2.8.

4.1. Control panel - version VI MAIN SWITCH (Fig.1 No.1) The main switch is situated on the upper part of the control panel and is used to switch the appliance on or off. When the marking of the knob points to "0" the appliance is switched off. When selecting the cooking programmes mentioned below the appliance is switched on automatically. The indicator light above the switch lights up. To switch off the appliance simply turn the main switch back to position ”0”. The indicator light goes out.
4.2. Control panel - version VII MAIN SWITCH (Fig.2 No.1) The main switch is situated on the upper part of the control panel and is used to switch the appliance on or off. When the marking of the knob points to “0” the appliance is switched off. When selecting the cooking programmes mentioned below the appliance is switched on automatically. The indicator light above the knob lights up. To switch off the appliance simply turn the main switch back to position ”0”. The indicator light goes out.
the indicator light above the symbol going out. Upon pressing the button the valve opens so that the water inside the steam generator can drain off. This operation is shown by the relative indicator light coming on. Once the boiler has been drained the button must be pressed again to close the valve. WASTE STEAM QUENCHING SYSTEM (Fig.2 No.25) This button can be used to activate or deactivate the thermostatic waste steam quenching system in all the cooking modes.
STEAM 1 (Fig.3 No.13) In this position the heating of the cooking chamber is activated as well as the steam generator heating elements in the proportion of 75% hot air and 25% steam. STEAM 2 - REGENERATION (Fig.3 No.14) In this position the heating of the cooking chamber is activated as well as the steam generator heating elements in the proportion of 50% hot air and 50% steam. INTERMITTENT FAN OPERATION (Fig.3 No.8) Intermittent fan operation is obtained in this position, i.e.
SPECIAL FUNCTIONS COOKING CHAMBER STEAM RELEASE EMPTYING THE STEAM GENERATOR (Fig.3 No.23) The appliance is fitted with a motor-operated discharge valve. Under normal conditions it is closed and this is shown by the indicator light above the symbol going out. Upon pressing the button the valve opens so that the water inside the steam generator can drain off. This operation is shown by the relative indicator light coming on.
4.4 Control panel - version X ON/OFF SWITCH COOK-STEP (Fig.4 No.1) The ON/OFF switch is used to switch the appliance and controls on or off. To switch the appliance on, lightly press the button; to switch off keep the button pressed down for about 3 seconds. This time delay avoids accidental switching off during a cooking cycle. When the appliance is switched off, this is indicated by the green indicator light above the button going out. When the appliance is switched on it lights up.
INTERMITTENT FAN OPERATION (Fig.4 No.8) Intermittent fan operation is obtained in this position, i.e. the fan starts and stops at programmed intervals. This intermittent control is activated when the regulator stops the heating of the cooking chamber; i.e. when the set temperature is reached. This control does not depend on the programmed fan speed. During the preheating stage, it is not activated. When inserting this variant, the indicator light above the button comes on. ECO-DELTA COOKING (Fig.4 No.
SPECIAL FUNCTIONS COOKING CHAMBER STEAM RELEASE EMPTYING THE STEAM GENERATOR (Fig.4 No.23) The appliance is fitted with a motor-operated discharge valve. Under normal conditions it is closed and this is shown by the indicator light above the symbol going out. Upon pressing the button the valve opens so that the water inside the steam generator can drain off. This operation is shown by the relative indicator light coming on.
STORAGE OF COOKING PROGRAMMES CHANGING AND COMPLETING COOKING PROGRAMMES To store a COOK-STEP or a set sequence in the ”PROG” mode under a well-defined programme number, press the and buttons simultaneously for about 1.5 seconds. The indicator light above the button blinks for 1.5 seconds and then remains fixed. The display relating to the cooking programmes is now activated and the increase and decrease buttons may be used to choose a programme number.
5. CLEANING AND MAINTENANCE The appliance must be cleaned thoroughly at the end of each working day. The appliance is protected against water jets (type of protection IPX5). This type of protection, however, does not permit cleaning with a water hose or high-pressure jets. General indications Under no circumstances must the drain pipe be obstructed, whether due to fats or food particles. It is therefore necessary to clean the drain pipe regularly and rinse it by flushing through with water.
Replacing the cooking chamber seal The cooking chamber seal is subject to ageing and deteriorates in time. It should therefore be replaced at the first sign of hardening, breaking or cracking. To replace, proceed as follows: Manually remove the seal from its groove. Clean any traces of dirt to be found in the seal groove and apply a little heat-resistant silicone in the four corners. Fit the new seal and apply silicone on the borders for sealing. First of all insert the seal into the four corners.
