UNPACKING AND INSTALLATION INSTRUCTIONS
3 ELECTRICAL GROUNDING INSTRUCTIONS
This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a grounding plug. It must be plugged into a wall receptacle that is properly installed and grounded in accordance with the National Electrical Code and local codes and ordinances. In the event of an electrical short circuit, grounding reduces risk of electric shock by providing an escape wire for the electric current.
WARNING - Improper use of the grounding plug can result in a risk of electric shock. Electrical Requirements
The oven is equipped with a 3-prong grounding plug. DO NOT UNDER ANY CIRCUMSTANCES CUT OR REMOVE THE GROUNDING PIN FROM THE PLUG. The Power Supply Cord and plug must be connected to a separate 120 Volt AC, 60 Hz, 15 Amp, or more branch circuit, single grounded receptacle. The receptacle should be located inside the cabinet directly above the Microwave Oven mounting location as shown in Figure 2. NOTE: 1. If you have any questions about the grounding or electrical instructions, consult a qualified electrician or serviceperson. 2. Neither Sharp nor the dealer can accept any liability for damage to the oven or personal injury resulting from failure to observe the correct electrical connection procedures.

4 HOOD EXHAUST DUCT
When the hood is vented to the outside, a hood exhaust duct is required. All ductwork must be metal; absolutely do not use plastic duct. Check that all connections are made securely. Please read the following carefully: Exhaust connection: The hood exhaust has been designed to connect to a standard 3-1/4 X 10 rectangular duct. If round duct is required, a rectangular-to-round adapter must be used. Rear exhaust: If a rear or horizontal exhaust is to be used, care should be taken to align the exhaust with the space between the studs, or wall should be prepared at the time it is constructed by leaving enough space between wall studs to accommodate exhaust. Maximum duct length: For satisfactory air movement, the total duct length of 3-1/4 X 10 rectangular or 6 diameter round duct should not exceed 140 feet. Elbows, adapters, wall caps, roof caps, etc. present additional resistance to air flow and are equivalent to a section of straight duct which is longer than their actual physical size. When calculating the total length, add the equivalent lengths of all transitions and adapters plus the length of all straight duct sections. Figure 3 shows the approximate feet of equivalent length of some typical ductwork parts. Use the values in parentheses for calculating air flow resistance equivalent, which should total less than 140 feet.

nor turn the turntable over so that a large dish could be placed in the oven. The turntable will turn both clockwise and counterclockwise.
ALWAYS have food in the oven when it is on to absorb

the microwave energy.

ABOUT FOOD
FOOD Eggs, sausages, nuts, seeds, fruits & vegetables DO Puncture egg yolks before cooking to prevent explosion. Pierce skins of potatoes, apples, squash, hot dogs and sausages so that steam escapes. Use specially bagged popcorn for the microwave oven. Listen while popping corn for the popping to slow to 1 or 2 seconds or use special POPCORN pad. Baby food Transfer baby food to small dish and heat carefully, stirring often. Check temperature before serving. Put nipples on bottles after heating and shake thoroughly. Wrist test before feeding. General Cut baked goods with filling after heating to release steam and avoid burns. Stir liquids briskly before heating and allow to stand 20 seconds after heating before stirring or drinking to avoid eruption. Use deep bowl, when cooking liquids or cereals, to prevent boilovers. DONT Cook eggs in shells. Reheat whole eggs. Dry nuts or seeds in shells.

Popcorn

Pop popcorn in regular brown bags or glass bowls. Exceed maximum time on popcorn package.
Heat disposable bottles. Heat bottles with nipples on. Heat baby food in original jars.
Heat or cook in closed glass jars or air tight containers. Can in the microwave as harmful bacteria may not be destroyed. Deep fat fry. Dry wood, gourds, herbs or wet papers.
INFORMATION YOU NEED TO KNOW
ABOUT UTENSILS AND COVERINGS
It is not necessary to buy all new cookware. Many pieces already in your kitchen can be used successfully in your new microwave oven. Make sure the utensil does not touch the interior walls during cooking. becomes very hot should not be used.
The following coverings are ideal:
Paper towels are good for covering foods for reheating and absorbing fat while cooking bacon. Wax paper can be used for cooking and reheating. Plastic wrap that is specially marked for microwave use can be used for cooking and reheating. DO NOT allow plastic wrap to touch food. Vent so steam can escape. Lids that are microwave-safe are a good choice because heat is kept near the food to hasten cooking. Oven cooking bags are good for large meats or foods that need tenderizing. DO NOT use metal twist ties. Remember to slit bag so steam can escape.

ABOUT SAFETY

Check foods to see that they are cooked to the United States Department of Agriculture's recommended temperatures. ALWAYS use potholders to prevent burns when handling utensils that are in contact with hot food. Enough heat from the food can transfer through utensils to cause skin burns. Avoid steam burns by directing steam away from the face and hands. Slowly lift the farthest edge of a dish's covering and carefully open popcorn and oven cooking bags away from the face. Stay near the oven while it's in use and check cooking progress frequently so that there is no chance of overcooking food. NEVER use the cavity for storing cookbooks or other items. Select, store and handle food carefully to preserve its high quality and minimize the spread of foodborne bacteria. Keep waveguide cover clean. Food residue can cause arcing and/or fires. Use care when removing items from the oven so that the utensil, your clothes or accessories do not touch the safety door latches.

TO SET POWER LEVEL

There are eleven preset power levels. Using lower power levels increases the cooking time which is recommended for foods such as cheese, milk and long slow cooking of meats. Consult cookbook or recipes for specific recommendations. When the defrost time is complete, a long tone will sound and END will appear in the display.

MANUAL DEFROST

If the food that you wish to defrost is not listed on the DEFROST CENTER CHART or is above or below the limits in the Amount column on the DEFROST CENTER CHART (see page 27), you need to defrost manually. You can defrost any frozen food, either raw or previously cooked, by using Power Level for 30%. Follow the exact 4-step procedure found under To Set Power Level. Estimate defrosting time and press POWER LEVEL pad eight times for 30% power. For either raw or previously cooked frozen food the rule of thumb is approximately 4 minutes per pound. For example, defrost 4 minutes for 1 pound of frozen spaghetti sauce. Always stop the oven periodically to remove or separate the portions that are defrosted. If food is not defrosted at the end of the estimated defrosting time, program the oven in 1 minute increments on Power Level 30% until totally defrosted. When using plastic containers from the freezer, defrost only long enough to remove from the plastic in order to place in a microwave-safe dish.

COOKING CONDITION

Program desired cooking time touching the NUMBER pads. When the START button is touched, the following operations occur: 1. The contacts of relays are closed and components connected to the relays are turned on as follows. (For details, refer to Figure O-2) RELAY RY1 RY2 RY3, RY4 RY5, RY6 CONNECTED COMPONENTS Oven lamp / Fan motor / Turntable motor Power transformer Hood fan motor Hood lamp
POWER LEVEL P-0 TO P-90 COOKING
When Variable Cooking Power is programmed, the 120 volts A.C. is supplied to the power transformer intermittently through the contacts of relay (RY2) which is operated by the control unit within an interval second time base. Microwave power operation is as follows: VARI-MODE ON TIME Power 10(P-HI) 32 sec. (100% power) Power 9(P-90) 30 sec. (approx. 90% power) Power 8(P-80) 26 sec. (approx. 80% power) Power 7(P-70) 24 sec. (approx. 70% power) Power 6(P-60) 22 sec. (approx. 60% power) Power 5(P-50) 18 sec. (approx. 50% power) Power 4(P-40) 16 sec. (approx. 40% power) Power 3(P-30) 12 sec. (approx. 30% power) Power 2(P-20) 8 sec. (approx. 20% power) Power 1(P-10) 6 sec. (approx. 10% power) Power 0(P-0) 0 sec. (0% power) OFF TIME 0 sec. 2 sec. 6 sec. 8 sec. 10 sec. 14 sec. 16 sec. 20 sec. 24 sec. 26 sec. 32 sec.
2. 120 volts A.C. is supplied to the primary winding of the power transformer and is converted to about 3.3 volts A.C. output on the filament winding, and approximately 2000 volts A.C. on the high voltage winding. 3. The filament winding voltage heats the magnetron filament and the H.V. winding voltage is sent to a voltage doubler circuit. 4. The microwave energy produced by the magnetron is channelled through the waveguide into the cavity feedbox, and then into the cavity where the food is placed to be cooked. 5. Upon completion of the cooking time, the power transformer, oven lamp, etc. are turned off, and the generation of microwave energy is stopped. The oven will revert to the OFF condition. 6. When the door is opened during a cook cycle, monitor switch, door sensing switch, primary interlock switch, relay (RY1) and secondary interlock relay (RY2) are activated with the following results. The circuits to the cooling fan motor, the turntable motor, and the high voltage components are de-energized, the oven lamp remains on, and the digital read-out displays the time still remaining in the cook cycle when the door was opened. 7. The monitor switch is electrically monitoring the operation of the primary interlock switch and secondary interlock

Note: The ON/OFF time ratio does not correspond with the percentage of microwave power, because approx. 3 seconds are needed for heating of the magnetron filament.

THERMAL CUT-OUT (CAVITY )
This thermal cut-out is located on the bottom of the oven cavity. It is designed to prevent damage to the oven unit if the food in the oven catches fire due to overheating produced by improper setting of cooking time or failure of control unit. Under normal operation, the thermal cut-out remains closed. However, the thermal cut-out will open at 293F (145C) causing the oven to shut down. The defective thermal cutout must be replaced with a new one.
The monitor switch is activated (the contacts opened) by the latch head on the door while the door is closed. The switch is intended to render the oven inoperative by means of blowing the monitor fuse when the contacts of the secondary interlock relay (RY2) and primary interlock switch fail to open when the door is opened. Functions: 1. When the door is opened, the monitor switch contact close (to the ON condition) due to their being normally closed. At this time the secondary interlock relay (RY2) and primary interlock switch are in the OFF condition (contacts open) due to their being normally open contact switches. And the contacts of relay (RY1) are in the ON condition (contacts close). 2. As the door goes to a closed position, the monitor switch contacts are first opened and then the door sensing switch and the primary interlock switch contacts close. (On opening the door, each of these switches operate inversely.)
The turntable motor rotates the turntable located on the bottom of the oven cavity, so that the foods on the turntable cook evenly during cooking. Turntable will turn in either direction. The turntable motor can be turned off by touching TURNTABLE ON/OFF pad.

COOLING FAN MOTOR

The cooling fan motor drives a blade which draws external cool air. This cool air is directed through the air vanes surrounding the magnetron and cools the magnetron. This air
is channelled through the oven cavity to remove steam and vapors given off from the heating foods. It is then exhausted through the exhausting air vents at the oven cavity.
This air is then expelled either vertically or horizontally through the customer supplied duct system, or discharged back into the kitchen.

HOOD FAN MOTOR

The hood fan motor is a two-speed, single-phase, double pole induction type, requiring a hood fan capacitor. It is located outside the upper rear part of the oven cavity, is to remove, from around the oven, hot air rising from the conventional electric or gas range over which it is installed.
The hood lamps are mounted at the hood lamp angle on the base cover. The hood lamps can be turned off and on by touching the LIGHT HI/ LO button. And also the brightness can be varied to high or low by touching the LIGHT HI/ LO button.

TROUBLESHOOTING GUIDE

MICROWAVE OUTPUT POWER

The following test procedure should be carried out with the microwave oven in a fully assembled condition (outer case fitted). HIGH VOLTAGES ARE PRESENT DURING THE COOK CYCLE, SO EXTREME CAUTION SHOULD BE OBSERVED. Power output of the magnetron can be measured by performing a water temperature rise test. This test should only be used if above tests do not indicate a faulty magnetron and there is no defect in the following components or wiring: silicon rectifier, high voltage capacitor and power transformer. This test will require a 16 ounce (453cc) measuring cup and an accurate mercury thermometer or thermocouple type temperature tester. For accurate results, the following procedure must be followed carefully: 1. Fill the measuring cup with 16 oz. (453cc) of tap water and measure the temperature of the water with a thermometer or thermocouple temperature tester. Stir the thermometer or thermocouple through the water until the temperature stabilizes. Record the temperature of the water. 2. Place the cup of water in the oven. Operate oven at POWER 10(HIGH) selecting more than 60 seconds cook time. Allow the water to heat for 60 seconds, measuring with a stop watch, second hand of a watch or the digital read-out countdown. 3. Remove the cup from the oven and again measure the temperature, making sure to stir the thermometer or thermocouple through the water until the maximum temperature is recorded. 4. Subtract the cold water temperature from the hot water temperature. The normal result should be 29.2 to 54.2F(16.2 to 30.1C) rise in temperature. If the water temperatures are accurately measured and tested for the required time period the test results will indicate if the magnetron tube has low power output (low rise in water temperature) which would extend cooking time or high power output (high rise in water temperature) which would reduce cooking time. Because cooking time can be adjusted to compensate for power output, the magnetron tube assembly should be replaced only if the water temperature rise test indicates a power output well beyond the normal limits. The test is only accurate if the power supply line voltage is 120 volts and the oven cavity is clean.

B POWER TRANSFORMER TEST

1. 2. 3. 4.

5. 6. 7. 8.

Disconnect the power supply cord, and then remove outer case. Open the door and block it open. Discharge high voltage capacitor. Disconnect the primary input terminals and measure the resistance of the transformer with an ohmmeter. Check for continuity of the coils with an ohmmeter. On the R x 1 scale, the resistance of the primary coil should be less than 1 ohm and the resistance of the high voltage coil should be approximately 83 ohms; the resistance of the filament coil should be less than 1 ohm. Reconnect all leads removed from components during testing. Reinstall the outer case (cabinet). Reconnect the power supply cord after the outer case is installed. Run the oven and check all functions.
PROCEDURE LETTER COMPONENT TEST
(HIGH VOLTAGES ARE PRESENT AT THE HIGH VOLTAGE TERMINAL, SO DO NOT ATTEMPT TO MEASURE THE FILAMENT AND HIGH VOLTAGE.)
C HIGH VOLTAGE RECTIFIER TEST
Disconnect the power supply cord, and then remove outer case. Open the door and block it open. Discharge high voltage capacitor. Isolate the rectifier from the circuit. Using the highest ohm scale of the meter, read the resistance across the terminals and observe, reverse the leads to the rectifier terminals and observe meter reading. If a short is indicated in both directions, or if an infinite resistance is read in both directions, the rectifier is probably defective and should be replaced. 5. Reconnect all leads removed from components during testing. 6. Reinstall the outer case (cabinet). 7. Reconnect the power supply cord after the outer case is installed. 8. Run the oven and check all functions. NOTE: Be sure to use an ohmmeter that will supply a forward bias voltage of more than 6.3 volts.
D HIGH VOLTAGE CAPACITOR TEST
Disconnect the power supply cord, and then remove outer case. Open the door and block it open. Discharge high voltage capacitor. If the capacitor is open, no high voltage will be available to the magnetron. Disconnect input leads and check for short or open between the terminals using an ohmmeter. Checking with a high ohm scale, if the high voltage capacitor is normal, the meter will indicate continuity for a short time and should indicate an open circuit once the capacitor is charged. If the above is not the case, check the capacitor with an ohmmeter to see if it is shorted between either of the terminals and case. If it is shorted, replace the capacitor. Reconnect all leads removed from components during testing. Reinstall the outer case (cabinet). Reconnect the power supply cord after the outer case is installed. Run the oven and check all functions.
