Installation, Operation and Care of
MODEL HM1200 MICROWAVE OVEN
SAVETHESE INSTRUCTIONS
GENERAL
Microwave heat is generated inside the food rather than being conducted through the food as in conventional methods. Time is used to control the amount of heating that occurs.
Microwave energy is absorbed in proportion to the moisture content of the food. The microwave energy causes water molecules to vibrate at high speeds, resulting in friction (HEAT).
The Model HM1200 produces microwave energy in a magnetron where an electric current is changed to microwave energy by large magnets. From the magnetron, microwave energy is transmitted to the oven cavity where it is reflected, transmitted or absorbed.
Microwaves are reflected by metal (on interior walls and the rotating waveguide located underneath the ceramic tray). This assures that the microwaves are well distributed within the oven cavity and produces even heating or cooking of foods.
Microwaves pass through paper, glass and plastic much like sunlight shining through a window. Because these substances do not absorb or reflect the microwave energy, they make ideal food containers for microwave cooking.
Microwaves penetrate the food to a depth of about 3/4 to 11/2 inches where they excite molecules – especially water, fat and sugar. The excited molecules vibrate at a rate of 2.45 billion cycles per second which causes friction and produces heat. The internal heating of larger food volumes is done by conduction. The microwave heat produced in the outer 11/2 inches is conducted to the center of the food. Food continues to heat by conduction after microwave production has stopped. Microwaves dissipate and cannot be stored in food.
RADIO INTERFERENCE
There is a possibility of a small amount of interference with weak broadcast signals if the microwave oven is too close to a radio or TV or similar equipment. If interference is present, it may be reduced by: 1) Cleaning the door and sealing surface of the oven, 2) Increasing the separation of the oven from the receiving device or 3) Using an antenna to obtain stronger signal reception for the receiving device.
INSTALLATION
UNPACKING
Immediately after unpacking the microwave oven, check it for possible shipping damage. If this oven is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.
Before installing the oven, test the electrical service to make sure it agrees with the specifications on the data plate on the right side of the oven.
