Important Safety Information
!
WARNING
Read the following information to avoid possible exposure to microwave radiation:
The basic design of the 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 microwave 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.
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 ACP.
2. Before servicing the unit (if unit is operable) perform
the microwave leakage test.
9. IMPORTANT: Before returning a unit to a
customer, be sure to check for proper switch
interlock action.
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.
10. The 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.
11. All 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/cm2.
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 ACP ComServ immediately.
12. 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 a microwave
oven leakage meter that complies with US
Government CDRH / FDA / DHHS requirements
and or any other local government requirements.
The maximum leakage level allowed by ACP
2
is 4mw/cm .
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.
13. If servicer encounters an emission reading over
4mw/cm 2, the servicer is to cease repair and
contact the ACP ComServ Department
immediately for further direction. ACP
will contact the proper Government
Agency upon verification of the test results.
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.

Liquids such as water, coffee, or tea are able to
be overheated beyond the boiling point without
appearing to be boiling due to surface tension of the
liquid. Visible bubbling or boiling when the container
is removed from the microwave oven is not always
present. THIS COULD RESULT IN VERY HOT
LIQUIDS SUDDENLY BOILING OVER WHEN A
SPOON OR OTHER UTENSIL IS INSERTED INTO
THE LIQUID. To reduce the risk of injury to persons:
a. DO NOT overcook food. Carefully attend oven
when paper, plastic, or other combustible
materials are placed inside the oven to facilitate
cooking.
b. Remove wire twist-ties from paper or plastic
bags before placing bag in oven.
c.
If materials inside the oven ignite, keep oven
door CLOSED, turn oven off and disconnect
the power cord, or shut off power at the fuse or
circuit breaker panel.
i)
ii)
Do not overheat the liquid.
Stir the liquid both before and halfway through
heating it.
iii) Do not use straight-sided containers with narrow
necks.
iv) After heating, allow the container to stand in the
microwave oven for a short time before removing
the container.
v) Use extreme care when inserting a spoon or
other utensil into the container.
d. DO NOT use the cavity for storage. DO NOT
leave paper products, cooking utensils, or food
in the cavity when not in use.

All Amana and Menumaster microwave oven power outputs are rated using the IEC705
standards. Using the IEC705 test method requires precision measurements and equipment that
is not practical to be performed in the field. Using the test shown below will indicate if the oven
performance is satisfactory.
Test equipment required:
1000 ml test container and thermometer.
Digital watch / watch with a second hand for use on ovens with electromechanical timers.
Important Notes:
Low line voltage will cause low temperature rise / power output.
Ovens must be on a dedicated circuit, properly grounded, and polarized. Other equipment on the same
circuit may cause a low temperature rise / power output.
This test and results are not a true IEC705 test procedures and are only intended to provide servicers with
an easy means of determining if the microwave oven cooking output is correct.
Procedure
1. Fill the test container to the 1000 ml line with cool tap water.
NOTE:
Water temperature should be approximately 60!F / 16!C
2. Using the thermometer, stir water for five to ten seconds; measure, and record the temperature (T1).
3. Place test container of water in the center of oven cavity and close door.
4. Heat the water for a 33-second full power cycle.
NOTE:
Use a digital watch or a watch with a second hand for ovens with electromechanical timers.
5. At end of the cycle, remove test container. Using the thermometer, stir water for five to ten seconds and record
temperature (T2).
6. Subtract the starting water temperature (T1), from the ending water temperature (T2) to obtain the temperature
rise ( T).
7. If the temperature rise ( T) meets or exceeds the minimum, the test is complete. If the temperature rise ( T)
fails to meet the minimum temperature rise, test the line voltage to verify it is correct. Then repeat steps 1-6
making sure to change the water. If the temperature rise ( T) fails to meet the minimum temperature rise again
the oven will require service.
