Important Safety Information

WARNING

Read the following information to avoid possible exposure to microwave radiation: The basic design of the Amana Microwave Oven makes it an inherently safe device to both use and service.

However , there are some precautions which should be followed when servicing the Radarange to maintain this safety . These are as follows:

1. Always operate the unit from an adequately grounded outlet. Do not operate on a two-wire extension cord.

2. Before servicing the unit (if unit is operable) perform the microwave leakage test.

3. The oven should never be operated if the door does not fit properly against the seal, the hinges or hinge bearings are damaged or broken; the choke is damaged, (pieces missing, etc.); or any other visible damage can be noted. Check the choke area to ensure that this area is clean and free of all foreign matter.

4. If the oven operates with the door open and produces microwave energy , take the following steps: A. Tell the user not to operate the oven. B. Contact Maytag Amana Manufacturing

immediately.

5. Always have the oven disconnected when the outer case is removed except when making the "live" tests called for in the Service Manual. Do not reach into the equipment area while the unit is energized. Make all connections for the test and check them for tightness before plugging the cord into the outlet.

6. Always ground the capacitors on the magnetron filter box with an insulated-handle screwdriver before working in the high voltage area of the equipment compartment. Some types of failures will leave a charge in these capacitors and the discharge could cause a reflex action which could make you injure yourself.

7. Always remember that in the area of the transformer there is HIGH VOLTAGE. When the unit is operating keep this area clear and free of anything which could possibly cause an arc or ground, etc.

8. Do not for any reason defeat the interlock switches there is not valid reason for this action at any time; nor will it be condoned by Amana.

9. IMPORT ANT : Before returning a unit to a customer, be sure to check for proper switch interlock action.

10. Before returning a unit to a customer, be sure that the door spacing is reasonably uniform along the top, bottom, and sides, and that it measure 1/8" or less.

1 1. The Amana Microwave Oven should never be

operated with any components removed and/or bypassed or when any of the safety interlocks are found to be defective, or when any of the seal surfaces are defective, missing, or damaged.

12. All Amana microwave ovens meet all requirements of the radiation control for Health and Safety Act of 1968. Due to measurement uncertainties, the maximum leakage for the field will be 4mw/cm

13. To ensure that the unit does not emit excessive microwave leakage and to meet the Department of Health and Human Services guidelines, check the oven for microwave leakage using the Narda model 8100, 8200 Holaday HI1500, HI1501, or Simpson 380M leakage monitor as outlined in the instruction. The maximum leakage level allowed when following those instructions is 4mw/cm2.

14. If servicer encounters an emission reading over 4mw/cm2, the servicer is to cease repair and contact the Amana Service Department immediately for further direction. Amana Manufacturing will contact the proper Government Agency upon verification of the test results.

WARNING

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

Grounding Instructions

WARNING

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.

WARNING

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

WARNING

To avoid the risk of electrical shock or death, this equipment must be grounded.

This equipment 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 equipment 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. Models operate with 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.

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.

Wiring

A good service practice is never route wiring over terminals and/ or sharp edges. This applies to any wiring without regard to the circuit voltage. Wire installation 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.

WARNING

To avoid risk of electrical shock, personal injury or death; verify the oven is properly grounded and polarized.

Explanation

Polarization–This means that the larger slot must be

neutral and the small slot must be hot (live). Mispolarized–The outlet is miswired so that the larger slot is hot (live) and the smaller slot is neutral. Grounded–This means the round hole connection is connected to earth ground through a connection to the main power panel. Ungrounded–The round hole connection is not complete to earth ground and/or the main power panel.

Test Procedures (2 Methods)

Method #1

Purchase and use a ground monitor available under Amana Part Number R0193001 or it can be purchased locally. The lamps inside the monitor indicate a correctly or incorrectly wired outlet by instructions imprinted on the monitor body .

Method #2

Voltmeter - (Use scale over 125 Volts A.C.)

• Test A - "H" to "N" must indicate line voltage.

• Test B - "H" to "G" must indicate line voltage.

• Test C - "N" to "G" must indicate zero (0) volts.

Proper Grounding and Polarization of 120 Volts Wall Outlets

If "N" to "G" indicates line voltage the outlet is improperly polarized.

For the safety of our customers and the service technician ALL appliances have a three–prong power cord and MUST be connected to a properly polarized and
