Page 5: Installation Instructions
INSTALLATION INSTRUCTIONS MC Series Ovens Power Supply Requirements The MC–Series oven should be connected to a suitable electricity supply, which can cope with the switching-on surge that occurs with certain types of catering equipment, such as microwaves. Because of this requirement, we strongly recommend that a separate, suitably rated supply is installed for the oven. -
Page 6: Error Codes And Diagnostics
Error Codes and Diagnostics The MC–Series oven will identify some of the most common problems by flashing an error message code in the time display window. These are the error messages, and suggestions for repairing them. Door not fully shut. Close door fully. -
Page 7: A - Power Output Testing To Bs En 60335-2-25:1996
Procedure A - Power Output Test in accordance with BS EN 60335-2-25:1996 Annex AA This test is given in the BSI test standard for microwave ovens. It is reproduced below - not so that you can follow it, but to show you why it is impractical in normal conditions. A simplified procedure, which gives a good approximation to the BSI power output, is given in Procedure B which follows. -
Page 8: B - Power Output Testing
Procedure B - Simplified Power Test You will need: A thermometer capable of reading to ±0.1°C. A Polypropylene tray approximately 200 mm x 200 mm. A measuring jug. A calculator. Water which is at a temperature of 10°C ± 2°C. 1 Measure 1 litre of cold water into the tray using the measuring jug. -
Page 9: D - High Voltage Capacitor Test
Procedure D - High Voltage Capacitor Test You will need: A Digital Multi-meter (D.M.M.) A Megger or similar resistance meter using 500V d.c. 1 Isolate the oven from the mains supply. WARNING: 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. -
Page 10: F - Interlock Operation
DOOR INTERLOCK OPERATION Door Interlock Operation The door on the oven is monitored by four microswitches. Three of these are used in the conventional “Primary, Secondary and Monitor” switch arrangement shown below, while the fourth is a low-voltage switch linked directly to the control circuitry.
