(E) Check microwave leakage to verify compliance with

the Federal Performance Standard should be performed on each oven prior to release to the consumer.

WIRING

Good service practice is to never route wiring over terminals and/or sharp edges. This applies to any wiring without regard to the circuit voltage. Wire insulation material and thickness is designed and regulated for electrical spacing purpose only , but cannot always be relied upon because of possible cuts and/or abrasions, which can occur during servicing.

WA RNING

To avoid risk of electrical shock, injury, or death, make sure these grounding instructions are followed.

Grounding Instructions

WA RNIN G

Do not remove grounding prong when installing grounded appliance in a home or business that does not have three wire grounding receptacle, under no condition is grounding prong to be cut off or removed. It is the personal responsibility of the consumer to contact a qualified electrician and have properly grounded three prong wall receptacle installed in accordance with appropriate electrical codes.

Should a two prong adapter plug be required temporarily it is the personal responsibility of the consumer to have it replaced with properly grounded three prong receptacle or the two prong adapter properly grounded by a qualified electrician in accordance with appropriate electrical codes.

Servicing of Grounded Products

The standard accepted color coding for grounding wires is GREEN or GREEN WITH YELLOW STRIPE. These ground leads are NOT to be used as current carrying conductors. It is extremely important that the technician replace any and all grounds prior to completion of the service call. Under no condition should ground wire be left off causing a potential hazard to technicians and consumer.

Test Modes

Power Test (Traditional Test Method)

Test equipment required is Amana power test kit R0157397 (Fahrenheit), or Menumaster power test kit M95D5 (Celsius).

1. Fill the plastic container to the 1000 ml. line with cool tap water.

2. Using the thermometer; stir the water, measure, and record the water temperature. Initial water temperature should be approximately 60°F (16°C).

3. Place container on the center of the oven shelf and heat the water for

33 seconds for ovens with more than 1550 watts or 63 seconds for ovens with less than 1550 watts.

NOTE: Use a watch second hand, not the oven timer.

4. Stir the water , measure and record the temperature of the water after heating time is complete.

5. Subtract the starting water temperature (Step 2), from the ending water temperature (Step 4) to obtain the temperature rise (DT).

6. See the Traditional Power Test Temperature Chart below.

NOTES: • The IEC-705 test method requires precision measurements and equipment. It is not practical to

perform the IEC test in the field. To convert the traditional power test results to the approximate IEC705 rating, take the traditional power test results and add 100 watts per magnetron for the unit being tested.

Example: 1627  watts output using the traditional power test for model HDC18

+ 200  watts (2 magnetrons X 100 watts)

1827  Approximate IEC-705 results

• Always perform power test three times for accuracy, changing the water after each test is performed.

• Variation or errors in the test procedure will cause a variance in the temperature rise. Additional power tests should be made if temperature rise appears marginal.

• Low line voltage will cause lower temperature rise.

Microwave Energy Leakage Testing

Measurement With the Outer Case

WA RN IN G

Removed

Check for radiation leakage after servicing. Should the leakage be more than 4mW/cm2 inform Amana immediately . After repairing or replacing any radiation safety device, keep a written record for future reference, as required by D.H.H.S. and HEW regulations. This requirement must be strictly observed. In addition, the leakage reading must be recorded on the service repair ticket while at the customer’s location.

Equipment

• Electromagnetic radiation monitor

• 600 cc glass beaker

Procedure For Measuring Radiation Leakage

Note before measuring -

• Do not exceed meter full scale deflection. Leak monitor should initially be set to the highest scale.

• To prevent false readings the test probe should be held by the grip portion of the handle only .

• The scan speed is equal to one inch per antenna revolution or one inch per second if antenna speed is unknown.

• Areas to be checked are all door seal areas and any venting parts.

• Leakage with the outer panel removed, 4mW/cm2 or less.

• Leakage for fully assembled oven with door normally closed, 4mW/cm2 or less.

• Leakage for a fully assembly oven (before the latch switch (primary) is interrupted) while pulling the door, 4mW/cm2 or less.

DANGER

To avoid risk of personal injury or death avoid contacting any high voltage components.

Whenever you replace the magnetron, measure for radiation leakage before the outer case is installed and after all necessary components are replaced or adjusted. Special care should be taken in measuring around the magnetron.

Measurement With a Fully Assembled Oven

After all components, including the outer panel are fully assembled, measure for radiation leakage around the door periphery , the door viewing window , the exhaust opening, and air inlet openings.

Record Keeping and Notification After Measurement

1. After any adjustment or repair to a microwave oven, a leakage reading must be taken. Record this leakage reading on the repair ticket even if it is zero.

2. A copy of the repair ticket and the microwave leakage reading should be kept by the repair facility.

1 . Pour 275 ± 15 cc (9 oz ± 1/2 oz) of 20 ± 5°C. (68±

9°F.) water in a glass beaker which is graduated to 600 cc and place the beaker in the center of shelf.

2. Set the radiation monitor to 2450 MHz and use it following the manufacturer’s recommended test procedure to assure correct results.

3. While measuring the leakage, always use the two inch (5 cm) spacer supplied with the probe.

4. Press the start pad or turn on the timer and with the magnetron oscillating, measure the leakage by holding the probe perpendicular to the surface being measured.

T o avoid risk of electrical shock or death, this oven must be grounded.

WARNING

To avoid risk of electrical shock or death, do not alter the plug.

This oven 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 oven 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.

Consult a qualified electrician or servicer if grounding instructions are not completely understood, or if doubt exists as to whether the oven is properly grounded.

Do not use an extension cord. If the product power cord is too short, have a qualified electrician install a threeslot receptacle. This oven should be plugged into a separate 60 hertz circuit with the electrical rating as shown in the appropriate drawing. HDC21 and HDC18 require a 208-230 supply voltage. HDC10 and HDC12 require a 120 supply voltage. When a microwave oven is on a circuit with other equipment, an increase in cooking times may be required and fuses can be blown.

Unpacking Oven

• Inspect oven for damage such as dents in door or dents inside oven cavity .

• Report any dents or breakage to source of purchase immediately. Do not attempt to use oven if damaged.

• Remove all materials from oven interior.

• If oven has been stored in extremely cold area, wait a few hours before connecting power.

Radio Interference

Microwave operation may cause interference to radio, television, or similar a oven. Reduce or eliminate interference by doing the following:

• Clean door and sealing surfaces of oven according to instructions in “Care and Cleaning” section.

• Place radio, television, etc. as far as possible from oven.

• Use a properly installed antenna on radio, television, etc. to obtain stronger signal reception.

Oven Placement

• Do not install oven next to or above source of heat, such as pizza oven or deep fat fryer. This could cause microwave oven to operate improperly and could shorten life of electrical parts.

• Do not block or obstruct oven filter. Allow access for cleaning.

• Install oven on level countertop surface.

A—Allow at least 7 " (17.8 cm) of clearance around top and

sides of oven. Proper air flow around oven cools electrical components. With restricted air flow , oven may not operate properly and life of electrical parts is reduced.

B—Allow at least 2 9/16 " (6.5 cm) between air discharge on back

of oven and back wall.

Cooking Guidelines

The Amana Microwave Oven can make your job easier. Y ou’ll cook ahead and pre-portion more. Y ou’ll also spend less time preparing special-order dishes.

To be sure of consistently good results, you’ll want to remember a few simple guidelines.

Food Variables

Microwave cooking can be directly affected by different food variables.

The shape of foods can greatly affect the amount of cooking time. Foods that are flat and thin heat faster than foods which are chunky . For example, a casserole will cook faster in a flat dish, rather than if heaped in a small dish. Foods cut into small pieces will cook faster than large-shaped foods. Pieces should be of a uniform size and shape for more uniform cooking, or the smaller pieces will cook faster. The greatest amount of cooking takes place within ¾" of the food’s surface. The interior of large food items, or dense foods, is heated by the heat conducted from the outer food layer. The most uniform cooking occurs in flat, doughnut-shaped foods. For best results, cook foods together which have similar sizes and shapes.

The quantity or volume of a food can affect the amount of cooking time. As the volume of the food is increased, the time required to cook or heat the item increases almost proportionately . If twice the amount of food is placed in the oven, it will take almost twice as long to cook. To determine the time for larger quantities, multiply the individual serving time by the increased amount, then reduce the total cooking time by about 20%.

The starting temperature of foods affects the amount of cooking time. Each temperature degree that the food item is to raise must be supplied with a definite amount of energy . Lower initial starting temperatures require more energy and more time to cook. Therefore, refrigerator temperature foods require a longer cooking time than do room temperature foods. Foods already slightly warm will heat very quickly in the oven.

The moisture content of foods affects the amount of cooking time. The higher the moisture content is in a food the longer the amount of cooking time.

The fat and sugar content of foods affects the amount of cooking time. Foods containing high fat and sugar levels heat very quickly and may reach much higher temperatures than foods having low fat and sugar levels. Foods having lower fat and sugar levels require longer cooking times.

The arrangement of food within a microwave oven cavity affects the way in which the food cooks. A “round” arrangement is best. Use round utensils whenever possible. Also, arrange foods such as baked potatoes in a circle, rather than in rows, for cooking. When only one food item is being cooked, place it in the center of the oven glass shelf for cooking.

The density of foods can greatly affect the amount of cooking time. Porous foods, such as breads, cakes or pastries, will heat much more quickly than dense meats of the same size. Porous foods absorb microwaves quickly throughout. Meats absorb microwaves mostly at the exterior surface, and the interior is heated by conduction, increasing the cooking time. Meats can be cooked in a sauce, if desired. Due to the moisture content, a sauce will heat rapidly . The heat will transfer to the meat, so the meat will heat faster due to heat by conduction as well as by microwaves.

A–19 RS2240002 Rev . 0

Manipulation of Foods

Sometimes recipes suggest manipulating or moving food during cooking. There are several forms of manipulation:

Stirring is required less often in microwave cooking than in conventional cooking. In conventional cooking, you use a spoon to move food up from the bottom of a pan to evenly distribute the heat. In microwave cooking, you still stir to redistribute the heat within some foods, but you need to stir from the outside of a dish toward the inside or center. If a recipe states to stir once or twice during cooking, stir at approximately even intervals. For example, in a 12-minute cooking period, if a recipe states to stir twice, stir after 4 minutes of cooking and again, after 8 minutes of cooking. However, it is not necessary to be precise. Stir only when necessary . When using lower power levels or settings, less stirring is required. Some examples of foods which may require stirring are puddings, some casseroles, some sauces, some soups, and some egg dishes. Some foods can’t be stirred. These foods are rearranged or turned.

Some foods can’t be stirred and should be repositioned or rearranged during cooking. Some examples include baked potatoes, cupcakes (in custard cups), chicken pieces, and others. Rearranging allows for more even cooking of foods. Foods which are cooked, covered, or which are cooked using lower power levels, usually require little rearranging.

Microwave Utensils

Never use cooking containers or covers with any metal content. This includes all metal and enameled metalcore ware, foil, and metal-trimmed containers. Suitable cooking containers include those made of paper products, glass, china, cloth, and wicker baskets.

Recommended Not Recommended

Glass/ceramic Aluminum foil Natural fiber cloth Grocery bags Non-recycled paper Recycled paper Plastic Lead crystal Wood Newspapers

Metal Metallic trimmed china

Utensil Check T est

Use the following test to check utensils for microwave safeness.

1. Place glass measuring cup of water next to empty dish to be tested in microwave oven.

2. Heat on full power for one minute.

3. Check temperature of dish and water.

• If dish remains cool and water is hot, dish is

microwave safe.

• If dish is slightly warm, use for short term cooking.

• If dish is hot and water is cool, do not use. Dish

remains cool if not absorbing microwaves and microwaves are being absorbed by water. Dish becomes hot if absorbing microwaves.

There are actually two types of turning. Turning is done when foods cannot be stirred. Foods which are cooked, covered, or which are cooked at lower power levels usually require little turning.

T urning foods over: Turning foods over is done to distribute heat. Meat and poultry are two types of foods which are sometimes “turned over.” Examples include roasts, turkeys and whole chickens. Small meat items such as poultry pieces may need to be turned over when in casseroles, or when in a browning skillet.

Rotating or turning dishes: There are a few foods which cannot be stirred, rearranged or turned over. Therefore, the actual cooking dish is turned or rotated. A half-turn means to grasp the dish and turn the portion of the dish that faces the oven door around, until it faces the back of the oven. Examples of foods which are sometimes turned or rotated in a cooking dish include cakes, quiches, or soufflés. When cooking foods at lower power levels or Settings, less turning of the cooking dishes is required.

Cooking Hints

Cover foods for faster, more even cooking. Glass

lids, plastic wrap, plate covers or other paper products may be used. Do not seal. Instead, allow for steamventing at all times.

Pierce pouches, plastic wrap covers and all foods

with a thin skin or membrane, such as potatoes, squash, tomatoes, eggs, etc. This prevents an eruption in the oven and allows for expansion and/or the escape of steam.

Foods should be carefully plated. For best results, arrange food such as vegetables or casserole-type items evenly around the edge of the plate with slightly less depth in the center. The edges of food items should not overlap or overhang the rim of the container. Cover meats with gravy or au jus and moisten all dry foods other than bread or pastry items.

Do not stack food or plated dishes in your oven.

Instead, when cooking more than one serving or platters, all plates should be placed at the same level in the oven, with space between all containers.
