Installation and GROUNDING INSTRUCTIONS

Placement of the Oven

Locate the oven on a smooth, flat and stable surface. There should be no gap between the table surface and the bottom of the oven. Do not place the oven in a hot or damp area, ie. near a stove, sink or directly above heat lamps on a serving line. Free airflow around the oven is important. 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.

Grounding Instructions

This oven must be grounded electrically. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. The 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.

WARNING — improper use of the grounding plug can result in a risk of electric shock.

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 connected.

If it is necessary to use an extension cord, use only a three wire extension cord that has a three blade grounding plug, and a three slot receptacle that will accept the plug on the appliance. The marked rating of the extension cord should be equal to or greater than the electical rating of the oven.

Removal of Protective Film

A blue protective film is used to prevent scratching of the outer case during transportation. Peel the film from the exterior of the oven before installation or use.

Wiring Requirements

No other appliance should share the circuit with the microwave oven. If it does, the branch circuit fuse may overload and either cause the oven to heat slower than

expected or blow the fuse.

A.For Model NE-1257/NE-1258

The oven must be on a SEPARATE, 20 amp, 60 Hz-120 V GROUNDED CIRCUIT.

	120 V
NEMA#	Grounded
5-20P	Outlet
	NEMA# 5-20R

B.For Models NE-1757/NE-2157

1.This oven must be on a separate, 60 Hz GROUNDED CIRCUIT - minimum 15 amps for NE-1757; minimum 20 amps for NE-2157.

2.The microwave ovens are built to operate on 2 different voltages (230-240 V or 208 V). Be sure that the voltage selector connector (on the back of the oven) is set for your power supply (see

page 5). Using a higher voltage setting is dangerous and may result in overheating of the electrical components thus shortening their life expectancy or possibly causing a fire or other accident. Using a lower voltage will lower the power output of the oven, resulting in slower heating of the food. Panasonic is NOT responsible for damage resulting from the use of the oven with other than the specified voltage.

NE-1757	NE-2157
NEMA#	NEMA#

Caution

 1. Do not attempt to tamper with or make any adjustments or repairs to the door, control panel housing, safety interlock switches or any other part of the oven. Do NOT remove the outer panel of the oven. Repairs should only be done by a qualified service person.

 2. Do NOT operate the oven empty. The microwave energy will reflect continuously throughout the oven if no food or water is present to absorb energy.

 3. If a fire occurs in the oven, press the Stop/Reset Pad and LEAVE THE DOOR CLOSED. Disconnect the power cord, or shut off the power at the fuse or circuit breaker panel.

 4. Do NOT attempt to dry clothes, newspapers or other materials in the oven, as they may catch on fire.

 5. Do NOT use recycled paper products, as they may contain impurities which may cause sparks and/or fires.

 6. Do NOT use newspapers or paper bags for cooking.

 7. Do NOT hit or strike the control panel. Damage to controls may occur.

 8. POT HOLDERS may be needed when removing food from the oven. Heat is transferred from the hot food to the container.

 9. Do NOT store flammable materials next to, on top of, or in the oven. It could be a fire hazard.

10.Do NOT operate the oven without the spatter shields (located in the top of inner cavity) in place.

How Does The Microwave Work?

Microwaves are a form of high frequency radio waves similar to those used by a radio including AM, FM, and CB. They are, however, much shorter than radio waves; approximately five inches long. Electricity is converted into microwave energy by the magnetron tube. From the magnetron tube, microwave energy is transmitted to the oven cavity where it is: reflected, transmitted and absorbed.

Reflection

Microwave are reflected by metal just as a ball is bounced off a wall. A combination of stationary (interior walls) and rotating antenna, located underneath the bottom shelf and above the ceiling cover assure that the microwaves are well distributed within the oven cavity to produce even heating or cooking of foods.

Transmission

Microwave pass through some materials such as paper, glass and plastic much like sunlight shining through a window. Because these substances do not absorb or reflect the microwave energy, they are ideal materials for microwave oven heating containers when covered.

Absorption

During heating, microwaves will be absorbed by food. They penetrate to a depth of about 3⁄4 to 11⁄2 inches. Microwave energy excites the molecules in the food (especially water, fat and sugar molecules), and causes them to vibrate at a rate of 2,450,000,000 times per second. This vibration causes friction, and heat is produced just as you will feel heat produced if you vigorously rub your hands together. The internal heating of larger foods is done by conduction. The heat which is produced by friction is conducted to the center of the food. Foods also continue to heat by conduction during standing time. (“carry-over” cooking)

Because microwave dissipate, much like sunlight as it reaches the Earth’s surface, they are not stored in food.

Radio Inference

1.Operation of the microwave oven may cause interference to your radio, TV or similar equipment.

2.When there is interference, it may be reduced or eliminated by taking the following measures:

a.Clean door and sealing surfaces of the oven. (See Care of Your Microwave Oven found on page 16.)

b.Place the radio, TV, etc. away from the microwave oven as far as possible.

c.Use a properly installed antenna, to obtain stronger signal reception.
