IMPORTANT SAFETY INSTRUCTIONS

RECOGNIZE THIS SYMBOL AS A SAFETY MESSAGE

⚠

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 oven from an adequately

grounded outlet. Do not operate on a two-wire extension cord.

2. Before servicing the oven (if oven is operable)

perform the microwave leakage test.

3. The oven should NEVER be operated if the door

does not properly seat 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:

Tell the user not to operate the oven. 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 oven area while the oven 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 lter box with an insulated-handle

screwdriver before working in the high voltage area of the oven compartment. Some types of failures will leave a charge in these capacitors and

the discharge could cause a reex action which

could make you injure yourself.

7. ALWAYS remember that in the area of the

transformer there is HIGH VOLTAGE. When the

oven 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 no valid reason for this action at any time; nor will it be condoned by ACP.

9. IMPORTANT: Before returning an oven 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 eld will be 4mW/cm2.

12. To ensure that the oven 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/cm2.

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 verication

of the test results.

Introduction

Theory of Operation

Sequence of Operation

Part No. 16400033

Original Instructions

Theory of Operation

Utilizing technology that combines Convection and Hot Air-Impingement along with Microwaves, the ARX-MRX

family of High Speed Combination Ovens rapidly cook food without sacricing quality in a small footprint. The

controls allow either programmed or manual cooking to coordinate air velocity and microwave production as needed

to meet the cooking requirements of the specic product. The on-board catalytic converter allows for ventless

installation.

Sequence of Operation

The oven is turned “ON” and allowed to come up to the programmed cooking temperature.

With a Menu Item loaded into the oven cavity and the door closed, the operator can either select from a list of preprogrammed menus or input manual cooking instructions.

There are cooking stages that can have di󰀨erent levels of microwave energy and impingement air velocity.

Once initiated, the oven’s Controller will signal the Magnetron circuit to operate from 0 to 100% by modulating the

circuit on and o󰀨 (or on 100%) based on the program. Simultaneously, the Controller will regulate the Convection

Blower’s speed from 0 to 100% based on the program. At the end of each cooking stage, the oven can change to a

di󰀨erent microwave level and/or blower speed.

During these cooking stages, the oven controls the cooking temperature by energizing and de-energizing a heating element.

Oven Tests

All ACP 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 eld. Using the following

tests will indicate if the oven is performing satisfactorily.

Power Test

Set Up:

• Oven MUST be at room temperature for accurate results.

• Service Test Mode: Both Magnetrons.

Equipment:

• 1000ml test container

• Thermometer

Procedure:

1. Fill the test container with cool tap water, as close to 60°F (16°C) as possible.

2. Using the thermometer, stir the water for 10 seconds; measure and record the temperature.

3. Place the container of water in the center of the oven and close the door.

4. Heat the water on full power for 33 seconds.

5. At the end of the cycle, remove the container from the oven.

6. Once again, stir the water for 10 seconds, take another measurement and record.

7. Subtract the starting water temperature from the ending water temperature to obtain the temperature rise.

8. If the temperature rise meets or exceeds the nominal microwave energy output rating found on the oven’s model/serial tag, the test is complete.

9. If the temperature rise fails to meet the minimum, test the incoming line voltage to verify it is correct.

10. Before retesting replace the water as in Step 1.

Repeat Steps 2 – 7. If the temperature rise fails to meet the minimum, the oven needs to be serviced.

Microwave Leak Test

The leakage reading must be recorded on the service repair documentation while in the customer’s premises.

Check for radiation leakage after servicing.

Should the leakage be more than 4mW/cm2, Contact ACP ComServ. After repairing or replacing any microwave radiation safety device, keep a written record for future reference, as required by Federal CDRH / FDA / DHHS and State regulations.

Tools required for test:

• 600ml glass beaker

• Supply of cold water (68°F ± 9°F/ 20°C ±5°C)

• Microwave leakage meter

NOTE: Read and understand the following information and the procedure before performing the measurements.

Make sure the survey meter you are using has been calibrated and is suitable for measuring frequencies of 2,450 MHz.

Leakage meter should initially be set to the highest scale then adjust to lower scales to ensure low readings are measured on the most sensitive range.

When measuring the leakage, use the probe supplied with the instrument. Always hold the probe at right angles to the oven and point of measurement.
