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.
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
ACP ComServ 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.
9. IMPORTANT: Before returning a unit to a customer, be sure to check for
proper switch interlock action.
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.
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 is 4mw/cm 2.
13. If servicer encounters an emission reading over 4mw/cm2, 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.

OVEN PERFORMANCE TEST
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.

products or those containing ammonia, phosphates, chlorine, sodium or
potassium hydroxide (lye) can damage critical oven parts. Do not use water
pressure type cleaning systems. Use of unapproved cleaning agents will void
the terms of the warranty. Recommended Cleaning Supplies: damp towel, plastic
scouring pad, ACP Oven Cleaner (Item CL10) and ACP Oven Shield Oven Protectant
(Item SH10).
