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 electrical requirements are a 120 volt 60 Hz, AC only, 15 amp. or more protected electrical supply. It is recommended that a separate circuit serving only this appliance be provided.
The oven is equipped with a 3-prong grounding plug. It must be plugged into a wall receptacle that is properly installed and grounded. Should you only have a 2-prong outlet, have a qualified electrician install a correct wall receptacle.
A 3-prong adapter may be purchased and used temporarily if local codes allow. Follow package directions.
A short power-supply cord is provided to reduce risk of becoming entangled in or tripping over a longer cord.
Extension Cord
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 receptacle that will accept the plug on the microwave oven. The marked rating of the extension cord should be AC 115-120 volt, 15 amp. or more.
Be careful not to drape the cord over the countertop or table where it can be pulled on by children or tripped over accidentally.
Notes: 1. If you have any questions about the grounding or electrical instructions, consult a qualified electrician or service person.
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.

Radio or TV Interference

Should there be any interference caused by the microwave oven to your radio or TV, check that the microwave oven is on a different electrical circuit, relocate the radio or TV as far away from the oven as feasible or check position and signal of receiving antenna.

INSTALLATION

Because your Sharp Commercial Microwave Oven will be used frequently, place it so that there is easy access for all users.
1. Be sure all electrical requirements are met. See above. 2. Air intake openings are on the back of the unit. Install the unit at
least 2 inches (5.1 cm) away from the nearest wall to permit adequate ventilation for proper cooling and air flow in the oven. 3. Install the unit where no excessive heat or steam are generated. Do not place next to an oven or cooking surface. 4. The unit may be secured to a countertop or stand. There is a screw hole in the bottom of the unit. After the oven is permanently placed, drill a hole through the counter top for a 3/16 inch (0.48 cm) self- tapping screw. The hole should be 1 inch (2.5 cm) from the left side of the outer case cabinet and 7-1/8 (20.1 cm) inches back from the front edge of the cavity face plate.

Note: If you do not open the door when an audible signal sounds, the defrosting cycle will continue and the defrosting time will count down to 0.
TIPS: Allow foods to stand a few minutes after defrosting to equalize the temperature for better cooking results.
Check food after standing. If additional time is needed, continue to defrost with time cooking. It is better to defrost with 30% power for R-21LTF. For R-21LVF, it is better to defrost with Express Defrost continuously.
Foods that are the same thickness throughout defrost better. If foods have varied thickness, it may be necessary to shield the thin edges with small flat pieces of aluminum foil to prevent overdefrosting.

CARE AND CLEANING

VERY IMPORTANT CAUTIONS
DO NOT OPERATE the oven without the splash covers in place.
DO NOT REMOVE the ceramic shelf from the oven.
DO NOT OPERATE the oven without the air ventilation cover.
DO NOT USE commercial oven cleaners, abrasive or harsh cleaners or scouring pads on any part of your microwave oven.

Oven exterior
The outside of your oven can be easily cleaned with mild soap and water. Make sure to rinse thoroughly and dry the exterior with a soft towel.
Control panel
Care should be taken in cleaning the control panel. Open the door before cleaning to inactivate the control panel pads.

Using a cloth dampened with water only, gently wipe the panel until it becomes clean. Avoid the use of excess water. Do not use any sort of chemical or abrasive cleaner. To do so may cause severe damage to the panel and make programming impossible.

Caution for R-21LCF, R-21LCFS: Take care not to move the Light Up Dial from “0” during cleaning, or the oven will start as soon as you close the door.
Oven interior

1. For easy cleaning, wipe any spatters or spills with a soft damp cloth or sponge at the end of each day. For heavier spills, use mild soap and rinse thoroughly with hot water.
2. At least once a week, remove the splash covers and wash in a mild detergent solution. The splash covers are located on the back wall near the top of the oven and on the right side wall. The covers may be removed easily. Simply remove four clips (A) as shown in Fig. 1. Then remove the splash covers from the oven.

To replace the back splash cover (B), secure the cover to the oven side walls with two clips (A) as shown in Fig.1. To replace the side splash cover (C), insert two projections of the cover (C) into the holes of the oven right wall as shown in Fig 2. And secure the cover to the oven right wall with two clips (A) as shown in Fig 1.
Fig.2
Side splash cover (C)
3) Wipe any grease, spills or spatters on the door seal surfaces with a soft damp cloth or sponge so that they do not build up. The door seals must always be free of grease and spatters so that the door closes properly.
Door Wipe the door and window on both sides frequently with a damp cloth to remove any spills or spatters. Always keep the door seals and seal surfaces clean so that any grease, spills or spatters are not allowed to build up. Such a build-up could result in leakage of microwave energy from the oven.

COOKING GUIDE
Utensils
METAL 1) Frozen Precooked Foods in Foil Containers
When cooking foods in foil containers, the container should be no more than 1/2″ (1.3 cm) deep. The best method to use is, after removing the foil cover, return the metal container to the paper box or package it came in and place this entire unit in the microwave oven. There must be more food than metal, and the metal container must not touch the oven walls.
2) Metal Skewers Small metal skewers may be used if there is a large proportion of food to the amount of metal. If arcing does begin, stop the oven, remove the food and change to a wooden skewer. Whenever using metal foil, foil containers or metal skewers, be sure that the metal does not touch the sides of the oven.
GLASS, GLASS-CERAMIC, CERAMIC AND CHINA UTENSILS Most glass, glass ceramic, ceramic and china utensils are excellent for use in microwave ovens. Heatresistant glassware, unless it has metallic trim or metal portions, can almost always be used in the microwave oven, no matter whether it is clear or opaque. However, you must be careful not to use delicate glassware since it might crack from the heat of the food but not from the microwaves. Most dinner plates, unless they have metallic trim, are acceptable for heating foods. Utensils with metallic trim or metal parts, such as screws, bands, handles, etc. must be avoided. Cracked or crazed glazes or chips are also indications that a dish should not be used. Ceramic mugs or cups with glued on handles are also not recommended for use in a microwave oven.
PAPER GOODS For low heat cooking, such as reheating or very short cooking times and for foods with low fat, sugar or water content, paper is a good utensil for microwave oven use. Napkins, towels, plates, cups, cartons, paper freezer wrap and the paper pulp board that some meats come packed in are also convenient utensils for use in the microwave oven. Cardboard can also be used. Paper is used in the microwave oven as a moisture insulator. Wax coated paper plates and cups should be avoided since the high temperatures that the foods reach may cause the wax to melt. Plastic coated dishes, however, are fine for use in the microwave oven.
Wax paper and paper towels provide an excellent loose cover for foods and help prevent spatters. Do not use paper towels, plates or other utensils made from recycled paper. Recycled paper products may contain certain impurities which could cause the paper to ignite during microwave heating. Some paper products may contain harmful substances.
PLASTIC AND FOAM UTENSILS Plastic and foam dishes and containers should not be used for cooking foods with high fat or high sugar content since the heat of the food is too hot for the plastic and may cause it to melt or lose its shape. Cooking pouches designed to withstand boiling and freezing for conventional cooking, work well in the microwave oven. Do not close plastic cooking pouches with the metal tie wraps provided, since they get very hot and will melt the plastic wrap. Any closed pouch or cooking container should be pierced so that steam is allowed to escape. Do not attempt to cook in plastic storage bags as they will not withstand the heat of the food. Plastic wrap may be used to cover foods during cooking. Stretch-type plastic wraps are not suitable for use in the microwave oven because they form too tight a seal. Whenever removing plastic wrap that has been tightly formed around the utensil, just lift the plastic away from you so that the steam can vent and there will be no danger of scalding.
Melamine is not recommended for use in the microwave oven.
WICKER, WOOD AND STRAW Wicker, wood and straw may be used in the oven for short periods of time; however, they should not be used for high fat or high sugar content foods since the heat of the food could possibly char the utensil. Wooden handle scrapers, spatulas and spoons may be left in the microwave oven during the cooking process.
16

Guidelines for microwave heating
Several factors should be kept in mind when selecting utensils to be used for microwave heating. 1. A plate with a narrow rim of about 1/2-inch (1.3 cm) is recommended. This keeps the food all at the same level for more even, uniform heating. 2. Casseroles and sauced items should be heated in straight sided containers. 3. Containers should be chosen to be large enough to contain foods as they expand with heating. Milk products are especially subject to boil- overs. 4. Most foods heat better if they are covered. Covering retains the heat that has been created, reduces dehydration and helps keep the oven clean. There should be an opening for steam to escape from the food. Covers should also be non-metallic to allow for proper heating.
Techniques 1. Microwave cooking is ideal for times when you run out of certain items or for preparation during slow periods. 2. Avoid overcooking. Small portions of food should stand 2-3 minutes following cooking; during this standing time foods will complete cooking. Large portions require longer standing times. 3. When a range of times is given in a recipe (2-3 minutes), always cook the shorter amount of time and check for doneness. Foods can always be returned to the microwave for additional cooking. Overcooked foods are tough or dry. 4. Arrange foods with thicker portions or larger pieces toward the outside of the cooking container. Most foods cook more evenly and faster if covered. 5. The microwave oven is quite useful in reducing broiling times for steaks and chops. Partially prepare the meat in microwave oven, then broil for a shorter period of time. 6. Sliced meats should be at least 1/2-inch (1.3 cm) thick for best heating results. Turning the meat product over once during the heating process will yield more uniform heating.
Pastries 1. Placing rolls or muffins on a paper towel or napkin or wrapping in a paper towel eliminates excess moisture and gives best results. 2. Avoid overheating. Baked items will be hotter on the inside than on the outside. Overheating causes baked products to be dry and tough.
Breakfast Items 1. Eggs should be slightly undercooked when preparing them for later reheating in the microwave. Cool quickly and store covered. 2. Arrange foods on platter with easily heated items near center of plate (eggs) and denser items toward outside (sausage). 3. Do not cook eggs in the shell. Pressure will build up inside the shell and it will burst. Do not reheat cooked eggs unless they are scrambled or chopped. Puncture the yolk before cooking eggs.
Sandwiches 1. Pre-toast bread and cool on air rack. Egg and shortening rich bread gives best results. 2. Sandwich meats should be sliced very thin. When assembling sandwich, place thicker portions toward outside edges. 3. Cover sandwiches and refrigerate no longer than three hours. When ready to heat in the microwave, unwrap and place on paper towel or napkin. Most sandwiches should be heated uncovered unless wrapped in paper towel or napkin. The paper absorbs excess moisture, preventing the sandwich from becoming soggy. 4. Avoid overheating. Filling heats rapidly, and overheated sandwiches become dry and tough.
17

Casseroles 1. Arrange casseroles with larger pieces or bulk of food around the perimeter of the casserole; depress in center. 2. Casseroles should be heated covered with a non-metallic cover or plastic wrap except casserole with crusts. If tightly covered, puncture plastic wrap or loosen at one corner so steam can escape. Be careful when removing plastic wrap; pull wrap away from you with the tines of a fork. 3. Cover casseroles evenly with sauce or gravy before refrigerating.
Vegetables 1. Arrange vegetables with larger pieces around the perimeter of the dish; depress in center. 2. Small uniform sized vegetables like peas, diced carrots and corn heat easily in the microwave oven. A butter sauce will speed the process. 3. Heat vegetables covered with either a non-metallic cover or plastic wrap. If tightly covered, puncture plastic wrap or loosen at one corner so steam can escape. Be careful when removing plastic wrap; pull wrap away from you with the tines of a fork. 4. Most vegetables should be slightly undercooked when preparing for later reheating in the microwave. Cool quickly and store covered. 5. Microwaved vegetables retain their bright color, flavor and nutrients.
Defrosting (For R-21LTF, R-21LVF)
1. See page 12 for EXPRESS DEFROST directions. 2. Avoid over-defrosting. Foods should be removed from the microwave when they are still slightly icy
in the center. Allow foods to stand covered for 1 to 2 minutes to complete defrosting. 3. (For R-21LTF) SELECTAPOWER allows you to defrost food at the power level and speed you choose.
Generally defrosting is done at 30% or lower. To use SELECTAPOWER for defrosting, first program time followed by touching the SELECTAPOWER pad and the number pad for percentage of power level (for example, 3 represents 30% power). The microwave power will pulse on and off to defrost frozen foods gently without heating.
(For R-21LCF, R-21LCFS) See page 7 for DEFROSTING FROZEN FOODS CHART.
Timing guide
Since different foods heat at different rates of speed, there are several influencing factors that should be taken into consideration when heating foods with microwave energy.
1. The lower the initial temperature of a food, the longer it will take to heat in a microwave oven. 2. Since with a microwave oven you are heating with time rather than temperature, it is helpful to know
the starting temperatures of the foods. Foods held at room temperature will heat more quickly than refrigerated foods. 3. The different chemical makeups of foods affect the heating times. Highly salted foods heat faster than non- cured items. Animal fats heat more quickly than lean parts of meat. Fats in a colloidal state heat faster than protein (egg yolk cooks before the white). 4. The density of a food is determined by how compact the molecules are arranged within the food. A pound of roast beef is denser than a pound of bread. Even though they weigh the same, the bread contains more air and is therefore less dense. Denser foods require longer heating times. 5. The thicker the food, the longer the heating time. If two foods have the same density, the thinner food will heat before the thicker one. 6. The shape of the food also affects the heating time. Low round foods that are depressed in the center heat faster than highly mounded scooped foods. This has to do again with the density. The denser the mass to be heated, the longer the heating time. 7. The more food placed in the oven cavity at one time, the longer the heating time. This is because there is a constant level of energy coming from the magnetron tube during the heating process. If there are several food items in the oven, they will each absorb some of the energy thus making the total heating time longer. The time required for heating is not directly proportional to the increased amount of food. The heating time should be increased by about 80% for each additional like food item.

REMINDERS
1. Do not operate the oven empty. Either food or water should always be in the oven during operation to absorb microwave energy.
2. Limit use of metal to those specific examples given in this booklet. Generally, metal should not be used in the microwave oven during operation.
3. Do not heat eggs in the shell. Pressure will build up inside the shell and it will explode. Do not reheat cooked eggs unless they are scrambled or chopped. Puncture the yolk before heating eggs.
4. Do not heat oil or fat for deep fat frying. 5. Pierce the “skin” of potatoes, whole squash, apples or any fruit, vegetable or meat with a skin covering
before heating. 6. Use only popcorn packaged in special microwavable packages. Pop using 100% power. Listen
carefully when popping corn. When popping slows to one or two seconds between pops, remove from oven. Should you ever smell scorching, remove bag from oven immediately.If any unpopped kernels remain, do not try to re-pop; it may cause a fire. 7. Do not use paper towels, plates or other utensils made from recycled paper for microwave heating. Recycled paper products may contain certain impurities which could cause the paper to ignite during microwave heating. 8. Stir liquids briskly before heating and allow to stand at least for 20 seconds after heating before stirring or drinking to avoid eruption.
