SAFETY PRECAUTIONS

This device is to be serviced only by properly qualified service personnel. Consult the service manual for proper service procedures to ensure continued safety operation and for precautions to be taken to avoid possible exposure to excessive microwave energy.

PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY

• A) Do not operate or allow the oven to be operated with the door open.
• B) Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave source, and make repairs as necessary; (1) interlock operation, (2) proper door closing, (3) seal and sealing surfaces (arcing, wear, and other damage), (4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.
• C) Before turning on microwave power for any service test or inspection within the microwave generating compartments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections.
• D) Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the owner.
• E) A microwave leakage check to verify compliance with the Federal Performance Standard should be performed on each oven prior to release to the owner.

SPECIFICATIONS

CAUTIONS

• Unlike other appliances, the microwave oven is high-voltage and high-current equipment.
• Though it is free from danger in ordinary use, extreme care should be taken during repair.
• DO NOT operate on a 2-wire extension cord during repair and use.
• NEVER TOUCH any oven components or wiring during operation.
• BEFORE TOUCHING any parts of the oven, always remove the power plug from the outlet.
• For about 30 seconds after the oven stops, an electric charge remains in the high-voltage capacitor. When replacing or checking, you must discharge the high-voltage capacitor by shorting across the two terminals with an insulated screwdriver.
• Remove your watches whenever working close to or replacing the Magnetron.
• DO NOT touch any parts of the control panel circuit. A resulting static electric discharge may damage this P.C.B.
• NEVER operate the oven with no load.
• NEVER injure the door seal and front plate of the oven cavity.
• NEVER put iron tools on the magnetron.
• NEVER put anything into the latch hole and the interlock switches area.

MICROWAVE RADIATION

• Personnel should not be exposed to microwave energy which may radiate from the magnetron or other microwave-generating device it it is improperly used or connection.
• All input and output microwave connections, waveguide, flange, and gasket must be secure never operate the device without a microwave energy-absorbing load attached.
• Never look into an open waveguide or antenna while the device is energized.
• Proper operation of the microwave oven requires that the magnetron be assembled to the waveguide and cavity. Never operate the magnetron unless it is properly installed.
• Be sure that the magnetron gasket is properly installed around the dome of the tube whenever installing the magnetron.

THE OVEN IS TO BE SERVICED ONLY BY PROPERLY QUALIFIED SERVICE PERSONNEL.

INSTALLATIONS

BEFORE YOU BEGIN, READ THE FOLLOWING INSTRUCTIONS COMPLETELY AND CAREFULLY.

INSTALLING

1. Empty the microwave oven and clean inside it with a soft, damp cloth. Check for damage such as misaligned doors, damage around the door or dents inside the cavity or on the exterior.
2. Put the oven on a counter, table, or shelf that is strong enough to hold the oven and the food and utensils you put in it. (The control panel side of the oven is the heavy side. Use care when handling.)
3. Do not block the vent and the air intake openings. Blocking vent or air intake openings can cause damage to the oven and poor cooking results. Make sure the microwave oven legs are in place to ensure proper airflow.
4. The oven should not be installed in any area where heat and steam are generated, because they may damage the electronic or mechanical parts of the unit. Do not install the oven next to a conventional surface unit or above a conventional wall oven.
5. Use a microwave oven at an ambient temperature of less than 104°F(40°C).
6. Place the microwave oven as far away as possible from the TV, RADIO, COMPUTER, etc., to prevent interference.
7. Place the microwave oven on a sturdy and flat surface.

• A – Allow at least 11/2 inches (3.81 centimetres) of clearance around the top and sides of the equipment. Proper airflow around equipment cools electrical components. With restricted airflow, the oven may not operate properly and the life of electrical parts is reduced.
• B – Allow at least 3 inches from the door front to the edge of the countertop to avoid accidental tipping of the oven.

GROUNDING INSTRUCTIONS

• For personal safety, this appliance must be fully grounded at all times.
• In the event of an electrical short circuit, grounding reduces the risk of electrical shock.
• The plug must be plugged into an outlet that is properly installed and grounded.

WARNING

• Improper use of the grounding plug can result in a risk of electric shock.
• Do not, under any circumstances, cut or remove the third ground prong from the power cord plug.

CIRCUIT DESCRIPTION GENERAL DETAILS

• The low voltage transformer supplies the necessary voltage to the micom controller when power cord is plugged in.
• When the door is closed, the primary switch is ON, the secondary switch is ON, and the monitor switch opens (contact COM and NO).

WHEN SELECTING COOKING POWER LEVEL AND TIME

• The micom controller memorizes the function you set.
• The time you set appears in the display window.
• Each indicator light turns on to indicate that the stage has been set.

WHEN TOUCHING THE START PAD

• The coii of the reiay is energized by the micom controller.
• Power input is supplied to the high voltage transformer through the fuse to the primary switch and relay 2.
• Turntable rotates.
• The fan motor rotates and cools the magnetron by blowing the air (coming from the intake on the base- plate).
• The air is also directed into the oven to exhaust the vapor in the oven through the upper plate.
• Cooking time starts counting down.
• 3.3 volts AC is generated from the filament winding of the high voltage transformer. This 3.3 volts is applied to the magnetron to heat the magnetron filament through two noise-preventing choke coils.
• A high voltage of approximately 2100 volts AC is generated in the secondary of the high voltage transformer which is increased by the action of the high voltage diode and charging of the high voltage capacitor.
• The negative 4,000 Volts DC is applied to the filament of the magnetron.

WHEN THE OVEN IS SET AT ANY LEVEL EXCEPT MAXIMUM.

• The micom controller controls the ON-OFF time of relay 2 by the applied signal to vary the average output power of the microwave oven as POWER LEVEL. (refer to page 1-1)
• One complete cycle of relay 2 is 22 seconds.

WHEN THE DOOR IS OPENED DURING COOKING

• Both the primary switch and relay 2 cut off the primary winding voltage of the high voltage transformer.
• ON-OFF of relay 2 is coupled electrically with opening and closing of the secondary switch.
• When the door is opened, the secondary switch is opened and when the door is closed, the secondary switch is closed
• The cooking time stops counting down.
• Relay stops functioning.
• As the door is opened, if the contact of primary switch and relay2 and/or secondary switch fail to open, the fuse opens due to the large current surge caused by the monitor switch activation, which in turn stops magnetron oscillation.
