Installation Requirements

Installation Location
Place the microwave oven on a flat surface. Free airflow around the oven is important. Allow at least 4 inches of clearance around the top, sides, and back of the oven for proper ventilation. Do not place oven above a gas or electric range.

Electrical Requirements

The oven is designed to operate on a Standard 120 V/60 Hz household outlet. Be sure the circuit is at least 15 A or 20 A and the microwave oven is the only appliance on the circuit. It is not designed for 50 Hz or any circuit other than a 120 V/60 Hz circuit. No other electrical appliances or lighting circuits should be on this line. If in doubt, consult a licensed electrician.

Voltage Warning

The voltage used at the wall socket must be the same as specified on the oven name plate located on the back or on the side of the control panel of the oven. Using a higher voltage is dangerous and may result in a fire or other type of accident causing oven damage. Low voltage will cause slow cooking. If the microwave oven does not perform normally in spite of proper voltage, unplug and reconnect the power cord.

Do Not Block Air Vents

All air vents should be kept clear during cooking. If air vents are covered during oven operation the oven may overheat. To prevent damage to the oven, a sensitive safety device detects overheating and automatically turns the oven off. The oven cannot be used until it has cooled sufficiently.

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.

Consult a qualified electrician or service person if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded.
Use of an extension cord is not recommended. If the power supply cord is too short, have a qualified electrician or service person install an outlet near the appliance.
If it is necessary to use an extension cord, use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot socket that will accept the plug on the appliance. The marked rating of the extension cord must be equal to or greater than the electrical rating of the appliance.
Ensure proper ground exists before use.
Keep the electrical power cord dry and do not pinch or crush it in any way.

WARNING: Improper use of grounding can result in a risk of electric shock.

NOTE

A short power supply cord is provided to reduce the risks resulting from becoming entangled in or tripping over a longer cord.
Longer cord sets or extension cords are available and may be used if care is exercised in their use.
If a long cord or extension cord is used, (1) the marked electrical rating of the cord set or extension cord must be at least as great as the electrical rating of the appliance, (2) the extension cord must be a grounding-type 3-wire cord, and (3) the longer cord should not be draped over a counter or table where children could pull on it, or located where it could present a trip hazard.

Cookware Guide

Microwave-Safe Cookware: Use microwavable cookware.

Ovenproof Glass
- Ovenproof glassware that is treated for high intensity heat so it is heat-resistant is microwave-safe.
- Use utility dishes, loaf dishes, pie plates, cake plates, liquid measuring cups, casseroles and bowls without metal rims.
- Do not use delicate glassware, such as tumblers or wine glasses, as these might shatter when heated.
China
- Use bowls, cups, serving plates, pottery, stoneware, ceramic, and platters without metal rims or handles. Many containers made of these materials are microwave-safe, but test them before use.
Plastic
- Plastic Storage Containers: Use plastic dishes, cups, semi-rigid freezer containers and plastic bags only for short cooking times. Do not use them when cooking food for long periods or at high power levels, as the hot food will eventually warp or melt the plastic.
Plastic wrap (as a cover):
Lay the plastic wrap loosely over the dish and press it to the sides. Vent plastic wrap by turning back one edge slightly to allow excess steam to escape. The dish should be deep enough so that the plastic wrap will not touch the food. As the food heats it may melt the plastic wrap wherever the wrap touches the food.
Plastic Cooking Bags:
Provided they are specially made for cooking, cooking bags are microwave safe. Remember to make a slit in the bag so that steam can escape. Never use ordinary plastic bags for cooking in the microwave oven, as they will melt and rupture.
Plastic Microwave Cookware:
A variety of shapes and sizes of microwave cookware are available. You may be able to use items you already have on hand rather than investing in new kitchen equipment.
Paper
- Use paper towels, waxed paper, paper napkins, and paper plates with no metal rims or design. Look for the manufacturer’s label for use in the microwave oven.
- Paper plates and containers are convenient and safe to use in the microwave oven, provided that the cooking time is short and foods to be cooked are low in fat and moisture. Paper towels are also very useful for wrapping foods and for lining baking trays in which greasy foods such as bacon are cooked.
- Avoid colored paper products as the color may run. Do not use recycled paper products in the microwave oven. They may contain impurities which could cause arcing or fires when used in the microwave.
Tableware
- Many containers made of pottery, stoneware and ceramic are also microwave-safe. If in doubt consult the manufacturer’s literature or perform the microwave test.
- Do not put plates with painted decoration in the oven, as the paint may contain metal and cause arcing.

Microwave-Unsafe Cookware

Metal Containers/Metal Decoration
- Never use metal or metal-rimmed cookware in the microwave oven.
- Microwaves cannot penetrate metal. They will bounce off any metal object in the oven and cause arcing, an alarming phenomenon that resembles lightning.
- Metal shields the food from microwave energy and produces uneven cooking. Also avoid metal skewers, thermometers, foil trays, metal-rimmed or metal-banded dinnerware, casserole dishes, etc. The metal rim interferes with normal cooking and may damage the oven
Aluminum Foil
- Avoid large sheets of aluminum foil because they hinder cooking and may cause harmful arcing.
- Use small pieces of foil to shield poultry legs and wings.
- Keep ALL aluminum foil at least 1 inch from the side walls and door of the oven.
Wood
- Wood bowls and boards will dry out and may split or crack when you use them in the microwave oven.
- Baskets react in the same way.
Tightly Covered Cookware
- Be sure to leave openings for steam to escape from covered containers.
- Pierce plastic pouches of vegetables or other food items before cooking.
- Tightly closed pouches could explode.
Brown Paper
- Avoid using brown paper bags.
- They absorb too much heat and could burn.
Flawed or Chipped Cookware
- Any container that is cracked, flawed, or chipped may break in the oven.
Metal Twist Ties
- Remove metal twist ties from plastic or paper bags.
- They become hot and could cause a fire.

Testing Cookware before Use
Most heat resistant and non-metallic cookware is safe for use in your oven. However, some cookware may contain materials that are not suitable for microwave use. Follow the steps below to find out if cookware can be used in the microwave.

Place the container in question and a glass measuring cup filled with water next to each other inside the oven.
Heat the container and glass measuring cup for 1 minute at HIGH power.
- If the water heats up but the container remains cool to the touch, the container is microwave-safe.
- If the temperature of the water does not change but the container becomes warm, it is not safe for use in the microwave oven.

CAUTION

Some items with high lead or iron content are not suitable for microwave cooking.
Cookware should be checked to ensure that it is suitable for use in the microwave.
Always be careful when taking cookware out of the oven. Some dishes absorb heat from the cooked food and may be hot.

Cooking Guide

Cooking Tips
Carefully monitor the food in the microwave oven while it is cooking. Directions given in recipes to elevate, stir, etc., are the minimum steps recommended. If food is overcooked (dry), undercooked, or unevenly cooked, make adjustments before or during cooking to correct the problem.

Overcooked or Dry Food
- Sprinkling: Sprinkle low-moisture foods such as roasts and vegetables with water before cooking, or cover them to retain moisture.
- Density: Light, porous food such as cakes and breads cook more quickly than heavy, dense foods such as roasts and casseroles.
- Shielding: Cover the corners of square dishes with small strips of aluminum foil to prevent overcooking. Don’t use too much foil, and secure the foil to the dish. Foil can cause arcing if it gets too close to the oven walls during cooking.
- Bones and Fat: Bones conduct heat, and fat cooks more quickly than meat. Take care with bony or fatty cuts of meat.
Undercooked Food
- Covering: Cover food with a microwave-safe lid, parchment paper (not waxed paper), or plastic wrap to trap heat and steam and cook food more quickly.
- Standing Time: Let food stand for several minutes after being removed from the oven to allow it to finish cooking and help flavors blend and develop.
- Quantity: The more food you place in the oven, the longer the required cooking time.
- Temperature: Ice-cold ingredients take much longer to cook than room temperature ingredients.
Unevenly Cooked Food
- Stirring: Stir food from the outside toward the center during cooking, as food at the outside of the dish heats more quickly.
- Arranging: Turn food over several times during cooking. The upper portion of thick foods cooks more quickly than the lower portion.
- Shaping: Place the thickest portions of foods like meat, poultry or fish toward the outside of the cookware to help them cook more evenly. If possible, shape foods into thin rounds or rings.
Foods with Skin, Shell or Membrane
- Skin or Membrane: Pierce the outsides of foods like potatoes, sausages, or egg whites or yolks before cooking.
- Shell: Pierce or remove the shells from eggs, clams, oysters, or other shelled foods before cooking.
Defrosting Tips
- Remove fish, shellfish, meat, and poultry from its original wrapping paper or plastic package. Otherwise, the wrap close to the foods will hold steam and heat, which can cause the outer surface of the foods to be cooked.
- Remove any metal twist ties.
- Always slit or pierce plastic pouches or packaging.
- Open containers such as cartons before they are placed in the oven.
- If food is foil wrapped, remove foil and place the food in a suitable container.
- The length of defrosting time varies depending on the shape of the food and on how solidly the food is frozen.
- As food begins to defrost, separate the food into pieces so that they can defrost more easily.
- Turn over food during defrosting or standing time. Separate into pieces and remove food as required.
- Let food stand after defrosting. Food should still be somewhat icy in the center when removed from the oven.

Precautions

WARNING

Do not use your microwave oven to cook eggs in the shell. Pressure can build up inside the shell, causing it to burst.
Never operate the oven when it is empty. Food or water should always be in the oven during operation to absorb the microwave energy.
Place the front surface of the door three inches or more from the edge of a countertop to avoid accidental tipping of the microwave oven during normal use.
To program the oven, press the center of each button firmly. When a button is pressed correctly, a beep sounds and the oven is activated. Do not press several buttons at once.
Do not strike the control panel with silverware, utensils, etc. It may be damaged or broken.
Always be careful when taking cookware out of the oven. Some dishes absorb heat from the cooked food and may be hot. See the Cookware Guide section for more information.
To avoid breakage, allow cookware to cool before rinsing or submerging in water. Always allow the turntable to cool before removing it from the oven.
Do not use the oven to dry newspapers or clothes. They may catch fire.
Use thermometers that have been approved for microwave oven cooking.
The turntable must always be in place when you operate the oven.
