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 t 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

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 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 equipment 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.

immediately.

plugging the cord

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 eld will be 4mw/cm .

12. To ensure that the unit does not emit excessive microwave leakage and to meet the 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 .

13. If servicer encounters an emission reading over 4mw/cm contact the ACP ComServ Department immediately for further direction. ACP will contact the proper Government Agency upon verication of the test results.

, the servicer is to cease repair and

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.

IMPORTANT SAFETY INSTRUCTIONS

WARNING

When using electrical equipment, basic safety precautions should be followed to reduce the risk of burns, electrical shock, re, or injury to persons including the following.

1. READ all instructions before using equipment.

2. READ AND FOLLOW the specic “PRECAUTIONS TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY” on this page.

3. This equipment MUST BE GROUNDED. Connect only to properly GROUNDED outlet. See “ GROUNDING / EARTHING INSTRUCTIONS” on page 5.

4. Install or locate this equipment ONLY in accordance with the installation instructions in this manual.

5. Some products such as whole eggs and sealed containers—for example, closed glass jars—are able to explode and SHOULD NOT be HEATED in this oven.

6. Use this equipment ONLY for its intended use as described in this manual. Do not use corrosive chemicals or vapors in this equipment. This type of oven is specically designed to heat, cook, or dry food. It is not designed for industrial or laboratory use.

7. As with any equipment, CLOSE SUPERVISION is necessary when used by CHILDREN.

8. See door cleaning instructions on page A-4 of this owners manual.

9. DO NOT heat baby bottles in oven.

10. Baby food jars shall be open when heated and contents stirred or shaken before consumption, in order to avoid burns.

11 DO NOT operate this equipment if it has a

damaged cord or plug, if it is not working properly, or if it has been damaged or dropped.

12. This equipment, including power cord, must be serviced ONLY by qualied service personnel. Special tools are required to service equipment. Contact nearest authorized service facility for examination, repair, or adjustment.

13. DO NOT cover or block louvers or other openings on equipment.

15. DO NOT immerse cord or plug in water.

16. Keep cord AWAY from HEATED surfaces.

17. DO NOT let cord hang over edge of table or

counter.

18. For commercial use only.

PRECAUTIONS TO AVOID POSSIBLE

EXPOSURE TO EXCESSIVE MICROWAVE

ENERGY

A. DO NOT attempt to operate this oven with the door open since open door operation can result in harmful

exposure to microwave energy. It is important not to defeat or tamper with the safety interlocks.

B. DO NOT place any object between the oven front face and the door too allow soil or cleaner residue to

accumulate on sealing surfaces.

C. DO NOT operate the oven if it is damaged. It is particularly important that the oven door close properly and

that there is no damage to the:

1. door (bent)

2. hinges and latches (broken or loosened)

3. door seals and sealing surfaces.

D. The oven should not be adjusted or repaired by anyone except properly qualied service personnel.

SAVE THESE INSTRUCTIONS

IMPORTANT SAFETY INSTRUCTIONS

WARNING

To avoid risk of re in the oven cavity:

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.

d. DO NOT use the cavity for storage. DO NOT

leave paper products, cooking utensils, or food in the cavity when not in use.

CAUTION

To avoid personal injury or property damage, observe the following:

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:

i) Do not overheat the liquid. ii) 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.

WARNING

1. Do not deep fat fry in oven. Fat could overheat and be hazardous to handle.

2. Do not cook or reheat eggs in shell or with an unbroken yolk using microwave energy. Pressure may build up and erupt. Pierce yolk with fork or knife before cooking.

3. Pierce skin of potatoes, tomatoes, and similar foods before cooking with microwave energy. When skin is pierced, steam escapes evenly.

4. Do not operate equipment without load or food in oven cavity.

5. Microwave popcorn should not be popped in oven.

6. Do not use regular cooking thermometers in oven. Most cooking thermometers contain mercury and may cause an electrical arc, malfunction, or damage to oven.

7. Do not use metal utensils in oven.

8. Do not use aluminum foil in oven

9. Never use paper, plastic, or other combustible materials that are not intended for cooking.

10. When cooking with paper, plastic, or other combustible materials, follow manufacturer’s recommendations on product use.

11. Do not use paper towels which contain nylon or other synthetic bers. Heated synthetics could melt and cause paper to ignite.

12. Do not heat sealed containers or plastic bags in oven. Food or liquid could expand quickly and cause container or bag to break. Pierce or open container or bag before heating.

13. To avoid pacemaker malfunction, consult physician or pacemaker manufacturer about effects of microwave energy on pacemaker.

14. An authorized servicer MUST inspect equipment annually. Record all inspections and repairs for future use.
