PARAMETER SETTING OF THE UC RELAY CARD Before applying the procedure, check whether your oven is set in Celsius or Fahrenheit degrees. For this purpose, try to set the temperature at O. Select DRY mode. If the set temperature shows O: Celsius degrees, if it shows 32: Fahrenheit degrees. When you change the min UC relay card, there are two possibilities: - Keep the customer parameters (counters, C/ F, si mple/detailed display) * Recuperate one or more memory components from the old card and place them on the new card in the same support and in the same way. Switch Memories * Insert the new card. * Check the configuration key. - If you do not keep the customer parameters: * Change the card totally. * Programme the configuration key. 2.2 PARAMETER SETTING OF THE CONFIGURATION KEY Open the facia. Tilt the switch of the UC relay card on OF (towards the right).

MAINTENANCE To ensure the proper, long-lasting and safe functioning of the equipment, service twice a year by qualified personnel from our company, and especially: - Dismantle burners, checking and cleaning venturis. - Clean the nozzles. - Clean the ventilating apertures. - Investigate possible leaks. - Check controls, regulation and safety systems. - Check the hydraulic circuit and condenser. 5.1 SERVICING THE CONDENSER The water injection nozzle and the temperature sensor are to be checked and cleaned regularly.

16 Page 15 3BE390691NM 10/10 6. VERIFICATION OF TEMPERATURE SENSORS PROBE PT100 (1 point for the capacity probe, 1 point for the core probe). Component of the sensor PT100 PT100 Temperature sensor composed of a resistance sensor with the value of 100 ohms for a temperature of 0, ohms for a temperature of 100. The varia tion of the resistance depending on the temperature is linear. The reading of the resistance gives directly the measured temperature. The sensor is not polarised. The sensor is lengthened by a copper wire. Correspondence of Temperature in C and Resistance in Ω for PT100 sensor C

17 Page 16 3BE390691NM 10/10 How to read the chart: To find the resistance corresponding to the temperature of 164 C. Find the intersection of the line 160 C and the col umn 4 C. The reading shows Ohms. Check PT100 Ω MΩ Check sensor resistance with an ohmmeter gauged at 200 ohms (less than 107 ohms for 20 ). Check the sensor insulation between one of the leads and the metal part with the ohmmeter gauged at 20 megohms (a value over 15 megohms). Check the continuity between the screen and the metal part of the sensor.

18 Page 17 3BE390691NM 10/10 7. DOOR ADJUSTMENT AND CLOSING WARNING: This adjustment must be carried out everytime when the door or the door closing system is serviced (hinges, closing device...), or after a steam leak in the way of the capacity seal & 10 LEVEL OVENS - Check that the oven is levelled. - Door closed. Level the door by loosening both fixation screws of the upper hinge on the oven. Screws Door - Level the door, tighten and block the screws. - Loosen the fixation screw of the upper hinge on the door. Screw Door - Push the door against the seal so that tightness is perfect. Warning! It is useless to squeeze the seal flat; it will not result in better tightness. - Block the fixation screw of the hinge. - Bring the upper distance between the door and the capacity to the lower part of the door by loosening the fixation screws of the lower hinge. At this stage, if the procedure has been properly executed, the door should be at the same height as the oven top. If not, readjust before the next step

19 Page 18 3BE390691NM 10/10 - Open the door and measure the distance between the top of the door and the tip of the closing piston. - Measure the distance between the top of the oven and the bottom of the hook groove. Distance between the top and the piston tip Distance between the top and the groove bottom - The distance between the top of the oven and the closing hook must be 1 to 2 mm greater than the distance between the top of the door and the piston tip. If not, loosen the closing hook screw and adjust the distance LEVEL OVENS - Make sure that the oven is properly secured to the floor. Level the oven. - Door closed. Level the door by loosening both fixations screws of the upper hinge on the oven. Screws

20 Page 19 3BE390691NM 10/10 - Level the door, tighten and block the screws. - Loosen the fixation screw of the upper hinge on the door. Screw - Push the door against the seal so that tightness is perfect. Warning! It is useless to squeeze the seal flat; it will not result in better tightness. - Block the fixation screw of the hinge. - Bring the upper distance between the door and the capacity to the lower part of the door by loosening the fixation screws of the lower hinge.

21 Page 20 3BE390691NM 10/10 8. RENEWAL OF THE DRIVING SHAFT GASKET GENERALITIES The wear of gaskets arising from an unbalanced turbine due to settling lime scale. The main consequence of this wear results in steam leaks in the way of the driving shaft, in a modification of cooking results (coloration, drying). PROCEDURE FOR CHANGING THE GASKET - Open the ventilation duct. - Unscrew the holding screw of the water deflector and remove the deflector. Screw + deflector - Install the hub puller (3 points with flat tips) and extract the turbine Turbine Hub puller Driving shaft gasket - Remove the gasket

22 Page 21 3BE390691NM 10/10 - Grease the motor shaft with Biolub code: grease (Special lubricant for the food industry) to make fitting the rings easier. - Assemble the ring with the gasket (assembly code : ). - Install the assembly on the driving shaft. Rotate the driving shaft before putting the turbine back in place. Warning: - Check gasket/driving shaft co-axiality. - Run the motors (before reassembling the turbines) to check proper positioning of the ring and the gasket (they must not rotate together with the driving shaft). - Reassembly : carry out the procedure in reverse order.
