(a) Do not operate or allow the oven to be

operated with the door open.

(b) Make the following safety checks on all

ovens to be serviced before activating the

magnetron or other microwave source,

and make repairs as necessary:

(1) Interlock operation, (2) proper door closing,

(3) seal and sealing surfaces (arcing,

wear, and other damage),

(4) damage to or loosening of hinges and latches,

(5) evidence of dropping or abuse.

any service test or inspection within the microwave generating compartments,

check the magnetron, wave guide or

transmission line, and cavity for proper

alignment, integrity, and connections.

(d) Any defective or misadjusted components

in the interlock, monitor, door seal, and microwave generation and transmission

systems shall be repaired, replaced, or adjusted by procedures described in this

manual before the oven is released to the owner.

(e) A Microwave leakage check to verify

compliance with the Federal performance standard should be performed on each

oven prior to release to the owner.

Follow these special safety precautions. Although the microwave oven is completely safe during ordinary use, repair work can be extremely hazardous due to possible exposure to microwave radiation, as well as potentially lethal high voltages and currents.

1. All repairs should be done in accordance with the procedures described in this manual. This product

complies with Federal Performance Standard 21 CFR

2. Microwave emission check should be performed to prior to servicing if the oven is operative.

3. If the oven operates with the door open :Instruct the user not to operate the oven and contact

the manufacturer and the center for devices and radiological health immediately.

4. Notify the Central Service Center if the microwave leakage exceeds 5 mW/cm2.

5. Checkall grounds.

6. Do not power the MWO from a "2-prong"AC cord. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields.

7. When reinstalling the chassis and its assemblies, be sure to restore all protective devices, including:

nonmetallic control knobs and compartment covers.

8. Make sure that there are no cabinet openings through which people --particularly children--might insert objects and contact dangerous voltages. Examples: Lamp hole,ventilation slots.

9. Inform the manufacturer of any oven foundto have emission in excess of 5 mW/cm2 ,Make repairs to bring the unit into compliance at no cost to owner and try to determine cause. Instruct owner not to use oven until it has been brought into compliance.

CENTRAL SERVICE CENTER

10. Service technicians should remove their watches whilerepairing an MWO.

11. To avoidany possible radiation hazard,replace parts

in accordance with the wiring diagram. Also, use only the exact replacements for the following parts: Primary and secondary interlock switches, interlock

monitor switch.

12. If the fuse is blown by the Interlock Monitor Switch: Replace all of the following at the same time:

Primary, door sensing switch and power relay, as well as the Interlock Monitor Switch. The correct

adjustment of these switches is described elsewhere in this manual. Make sure that the fuse has the

correct rating for the particular model being repaired.

13. Design Alteration Warning: Use exact replacement parts only, i.e.,only those that are specified in

thedrawings and parts lists of this manual. This is especially important for the Interlock switches,

described above. Never alter or add to the mechanical or electrical design of the MWO.

Any design changes or additions will void the manufacturer's warranty. Always unplug the unit's

AC power cord from the AC power source before attempting to remove or reinstall any component or

assembly.

14. Never defeat any of the B+ voltage interlocks. Do not apply AC power to the unit (or any of its assemblies) unless all solid-state heat sinks are correctly

installed.

15. Some semiconductor ("solid state") devices are easily damaged by static electricity. Such components are called Electrostatically Sensitive

Devices (ESDs). Examples include integrated circuits and field-effect transistors. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground.

16. Always connect a test instrument's ground lead to the instrument chassis ground before connecting the positive lead; always remove the instrument's ground

lead last.

17. When checking the continuity of the witches or transformer, always make sure that the power is OFF, and one of the lead wires is disconnected.

18. Components that are critical for safety are indicated in the circuit diagram by shading, _or _.

19. Use replacement components that have the same ratings, especially for flame resistance and dielectric

strength specifications. A replacement part that does not have the same safety characteristics as the

original might create shock, fire or other hazards. NOTE : Connect the oven to a 20A. When

connecting the oven to a 15A,make sure that circuit breaker can operate.

PRECAUTION

There exists HIGH VOLTAGE ELECTRICITY with high current capabilities in the circuits of the HIGH VOLTAGE TRANSFORMER secondary and filament terminals. It is extremely dangerous to work on or near these circuits with the oven energized.

DO NOT measure the voltage in the high voltage circuit including filament voltage of magnetron.

The Microwave Oven is supported by a special bracket assembly (mounting system) supplied with the oven. The bracket assembly must be mounted to the wall with toggle bolts through the wall, and a lag screw

into a wall stud. After the bracket assembly is installed,

the unit can be slid over the two rails of the bracket assembly. Two bolts are run down through the cabinet

bottom and into the oven case to pull the oven up

against the cabinet bottom.

NOTE : For easier removal and personal safety it is recommended that two people remove this product.

II/ t

/ Mounting Plate

PRECAUTION

The mounting surface must be capable of supporting the cabinet load, in addition to the 64 pound product, plus additional loads of up to 50 pounds or a total weight of 114 pounds. This product cannot be installed to cabinet arrangements such as an island or peninsula. It must be mounted to both a top

cabinet and wall.

VENT BLOWER

The vent or exhaust blower is located at the top of the oven. It is shipped for recirculating exhaust but can be

changed to rear exhaust or vertical (See installation

instrustions on how to change and/or blower section on how to remove).

REMOVE SCREWS

COOKTOP LIGHTS

One 20-watt screw base halogen bulb is located on the bottom. The bulb is user replaceable by removing one

screw and lowering access cover.

A 40-watt screw base incandescent bulb is located in the top of the oven cavity at the front.

It is user replaceable by removing the top grill (2 screws. On the front of outer case.). The bulb is then accessible by removing a metal cover.

REUSABLE GREASE FILTERS

The metal filter trap grease released by foods on the cooktop. They also prevent flames from foods on the

cooktop from damaging the inside of the microwave.

For this reason, the filter must ALWAYS be in place when the hood the vent fan is used. The grease filter should be cleaned once a month, or as needed.
