7. SAFETY DEVICES
The appliance is fitted with the following safety devices:
-Fuses (see electrical circuit diagram) located behind the control panel.
To change a fuse unscrew and remove the retainer cap and replace the blown fuse with an identically rated component; the fuse rating value is specified on the relative dataplate.
-Oven chamber safety thermostat with manual reset, located behind the control panel; when this device trips, convection heating power is disconnected.
Notice: CONTACT YOUR AUTHORIZED SERVICE COMPANY TO PERFORM MANINTENANCE AND REPAIRS.
-Automatic reset thermal protection inside the cavity fan motor: this device trips in the event of overheating of the cavity fan motor; this
8. OPERATION CHECK
-Switch on the appliance in accordance with the following section "Instructions for use".
-With the aid of the Instruction Booklet, explain operation, routine maintenance, and cleaning to the user.
Important:
-Exercise due care since certain areas of the oven exterior become hot during use.
-Do not cover the exhaust outlets on top of the appliance.
9. SERVICING
All components requiring routine maintenance may be easily reached by opening the control panel, removing the left side panel, or removing the rear panel.
Danger: Live voltage is present with panels removed and unit switch on. Exercise extreme caution when work with live voltage.
NOTICE: Using any parts other than OEM original spare parts relieves the manufacturer of all warranty and liability.
10. TROUBLESHOOTING
Malfunctions may occur even when the appliance is used correctly.
Burner fails to light (message "burn" appears on display TM , see "Instructions for use" chapter 5).
Possible causes:
-The ignition electrode is incorrectly positioned or the insulation is damaged. The optimum distance from the outside of the electrode to the boiler burner is approximately 5 mm(8mm Mod. 20 GN1/1), while the equivalent distance for the convector burner is approximately 4.5 mm.
-The ignition / flame control device is damaged.
-The ignition electrode high tension lead is broken or shorting to ground.
-Insufficient gas pressure.
-Faulty gas valve.
-Burner fan unit damaged, insufficient air pressure in combustion chamber.
-Electronic control panel is damaged.
-Blown fuse, check electrical diagram.
-Oven chamber temperature probe damaged (error EPt1 - see
"Instructions for use" chapter 5).
-Temperature limiter trip.
-High room air humidity (condensation): ventilate the kitchen.
Burner flame extinguishes (message "burn" appears on display TM, see "Instructions for use" chapter 5).
Possible causes:
-Power supply polarity (Phase/Neutral) inverted.
-Electrical supply to oven is "Phase/Phase" type. In this case fit the special "Transformer Kit" available from the manufacturer on request.
-Faulty gas valve.
-Flame detector electrode incorrectly positioned or in open circuit.
-Burner fan unit damaged (lockout situation).
-Flame control device damaged
-High room air humidity (condensation): ventilate the kitchen.
Oven chamber temperature thermostat control is incorrect. Possible causes:
-Electronic control panel faulty.
-Oven chamber temperature probe is dirty, faulty, or interrupted, see error EPt1 (see "Instructions for use" chapter 5).
Oven fails to turn on. Possible causes:
-Electronic control panel is damaged.
-Fuse F2 blown due to damaged control circuit components.
Oven chamber lamps damaged
CAUTION: Before changing oven chamber lamps switch off the appliance.
11. LAYOUT OF MAIN COMPONENTS
(All work inside the appliance must be carried out exclusively by a trained installer authorised by the manufacturer)
Removing the control panel provides access to the following components:
Danger: Live voltage is present with panels removed and unit switch on. Exercise extreme caution when work with live voltage.
-Electronic circuit boards
-Oven chamber temperature limit thermostat
-Fuses
-Door microswitch
-Oven chamber lamp transformer
-Geared motor for the oven chamber pressure relief butterfly valve.
WARNING: Before servicing unit switch off power at the main circuit breaker and place a red tag on the breaker to indicate work is being done on the circuit.
Remove the appliance left hand side panel to gain access to all the other components.
