5 INSTALLATION 5.1 OVEN LOCATION AND POSITIONING PRODUCT DETAILS Choose a site away from major heat sources. DO NOT position so that hot air is drawn in from fryers, grills, griddles, etc. A heat barrier to the height of the oven must be installed if sited next to a burner, stove or range. Place the oven on a permanent nonslip/ nonflammable flat surface that is LEVEL, STABLE and STRONG enough for the oven and contents. Allow a minimum clearance (A) of 2 inches (50mm) around the oven for hot air to escape.
THIS APPLIANCE MUST BE EARTHED. FAILURE TO DO SO MAY RESULT IN ELECTRIC SHOCK AND DEATH. For all cord connected appliances: GROUNDING INSTRUCTIONS This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.

15 OVEN TESTING 15.1 Equipment required DANGER: Portable Appliance Tester (P.A.T.). Digital Multi-meter (D.M.M.). Megger / similar 500V d.c. resistance meter. Microwave detection / leakage meter. Temperature reader. Continuity meter. Door Spacer Kit (Part No. SA1109). Microwave safe 600ml glass beaker Microwave safe 2 litre container.
15.4 OVEN TESTS A 15.4.1 Enter Service mode (Servicing section). 15.4.2 Select the down arrow to display the individual Oven tests (A) for the oven to perform. 15.5 Microwave Power Test TESTING COMPONENTS Measuring the power output. Note: The power output is established under IEC 705 standard method which is only workable in Laboratory controlled conditions. Power output is also affected by line voltage under load, so this test is an approximation only. 15.5.
15.6 Microwave Leakage Test Note before measuring. Make sure that the survey meter you are using has been calibrated and is suitable for measuring frequencies of 2,450 MHz. Do not exceed meter full scale deflection, leakage meter should initially be set to the highest scale, then adjusted down as necessary to ensure that low readings are measured on the most sensitive range. To prevent false readings, hold the probe on the grip provided and move at 2.5cm/second.
15.7 Temperature Control Test TESTING COMPONENTS Measuring the oven cavity temperature. (Note; re-calibrating the Thermocouple with the SRB is normally only required when the Thermocouple has been replaced or the oven is under or over cooking.) Procedure: 15.7.1 Place the probe of a temperature reader (A) onto a heat sink or a metal plate in the centre of the oven cavity and close the oven door. 15.7.2 Select ‘Temperature Control Test’ (B) from the service mode tests.
15.8 Soak Test A 15.9 Recommission Test TESTING COMPONENTS Checking the oven cavity integrity. Procedure: 15.8.1 Place an oven/microwave safe container with approx. 2 litres of water into the oven. 15.8.2 Close the oven door and select ‘Soak Test’ (A) from the Service mode oven tests (maximum oven temperature, 50% microwave power, maximum fan speed). 15.8.3 Run the test (30 minutes), carefully checking the oven casing, joints and door seal for signs of steam or water escaping from the oven cavity. 15.8.
16 HIGH VOLTAGE COMPONENTS High voltages and large currents are present at the High Voltage Capacitor. It is very dangerous to work near this part when the oven is on. NEVER make any voltage measurements at the High Voltage circuits, including the magnetron filament. DANGER: BEFORE REMOVING THE OVEN CASING, ISOLATE THE OVEN FROM THE MAINS ELECTRICITY POWER SUPPLY; SWITCH OFF, DISCONNECT OVEN PLUG FROM WALL SOCKET, TURN OFF ISOLATOR SWITCH TO DISCONNECT FIXED WIRED OVENS AND LOCK-OFF.
High voltages and large currents are present at the High Voltage Capacitor. It is very dangerous to work near this part when the oven is on. NEVER make any voltage measurements at the High Voltage circuits, including the magnetron filament. 16.3.1 Disconnect and isolate the oven from the electricity supply. 16.3.2 Allow the oven to cool down. 16.3.3 Remove the oven casing. 16.3.4 Ensure that the High Voltage Capacitor is discharged before commencing work. 16.3.
17 MAINS VOLTAGE COMPONENTS 17.1 Door Interlock Adjustment TESTING COMPONENTS Located on the door hinges are 3 safety interlock microswitches, to prevent microwave emissions escaping when the oven door is opened: The Primary (SW3) breaks the electrical supply circuit to the transformers. The Secondary (SW2) breaks the microwave circuit if the primary fails. The Monitor switch (SW1) will short out the Microwave circuit blowing the fuse if both Primary and Secondary interlocks fail.
17.2 Convection Fan Motor & Controller 17.2.1 Convection Fan Motor. The convection motor Is a 3-phase AC motor having a maximum speed of 7200 rpm controlled by a motor speed controller. The windings are thermally protected and in the event of a thermal fault a trip inside the motor will operate and shut down the motor speed controller. 17.2.2 Motor Controller Provides a 3-phase AC switched mode drive to the convection motor and is controlled by a 0 - 10 Volt signal from the SRB.
18 OVEN COMPONENTS DANGER: BEFORE REMOVING THE OVEN CASING, ISOLATE THE OVEN FROM THE MAINS ELECTRICITY POWER SUPPLY; SWITCH OFF, DISCONNECT OVEN PLUG FROM WALL SOCKET, TURN OFF ISOLATOR SWITCH TO DISCONNECT FIXED WIRED OVENS AND LOCK-OFF. WARNING: ALLOW OVEN TO COOL. OBSERVE AND FOLLOW ALL SAFETY PRECAUTIONS INCLUDING THOSE DESCRIBED UNDER THE SAFETY REGULATIONS SECTION OF THIS MANUAL BEFORE ATTEMPTING A SERVICE OR REPAIR.

19 SRB & QTS Circuit Boards 19.1 SRB replacement 19.1.1 Disconnect and isolate the oven from the electricity supply. 19.1.2 Allow the oven to cool down. 19.1.3 Remove the oven casing. 19.1.4 Ensure that the High Voltage Capacitor is discharged before commencing work. 19.1.5 Taking anti-static precautions, disconnect all connections on the SRB. 19.1.6 Remove the PM (Personality Module) from the SRB and place safely aside. 19.1.7 Release retaining screws and remove the SRB. 19.1.
The PM on the SRB contains the Firmware. The PM on the QTS contains the Firmware, Oven Serial Number, Temperature Calibration, Cooking Programs, Application Icons and the Recipe Images. 19.3.1 With a new PM fitted and casing refitted, switch on the oven and tap the screen to hold and check the QTS and SRB versions (1) are the latest release, if not, execute a Firmware update using the latest versions. For details see ‘Firmware Updates’ (Servicing section). 19.3.
