Safety Precautions
PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY
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.
c. Before turning on microwave for 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
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.
- Proper operation of the microwave ovens requires that the magnetron be assembled to the wave guide and cavity. Never operate the magnetron unless it is properly installed.
- Be sure that the magnetron gasket is properly installed around the dome of the tube whenever installing the magnetron.
- Routine service safety procedures should be exercised at all times.
- Untrained personnel should not attempt service without a thorough review of the test procedures and safety information contained in this manual.
FOREWORD
Read this Manual carefully. Failure to adhere to or observe the information in this Manual may result in exposing yourself to the Microwave Energy normally contained within the oven cavity.
ADJUSTMENT PROCEDURES
To avoid possible exposure to microwave energy leakage, adjust the door latches and interlock switches, using the following procedure.
ONLY AUTHORIZED SERVICE PERSONNEL SHOULD MAKE THIS ADJUSTMENT.
The Interlock Monitor and Primary Interlock Switch acts as the final safety switch protecting the user from microwave energy. The terminals between “COM” and “NC” of the Interlock Monitor must close when the door is opened. After adjusting the Interlock Monitor Switch, make sure that it is correctly connected. See Figures 1-a and 1-b throughout this procedure.
CHECK THE DOOR LATCH AND SWITCH CLOSINGS.
NOTE: The outer cover of the microwave oven is removed.
-
Set the microwave oven on its side so that you can see the latch board and the switches, as shown in Figure 1-a.
-
Close the door tightly and check gaps A and B to be sure they are no more than 1/64″ (0.5 mm). See Figure 1-b for close-up view of gaps A and B (door latches). If all gaps are less than 1/64″ (0.5 mm), adjustment of the latch board may not be necessary. Go to Steps 5 and 6 to check the sequence of the switches.
NOTE: To correct sequence of the Primary Interlock Switch, Secondary Interlock Switch and the Interlock Monitor Switch is very important.
If any gap is larger than 1/64″ (0.5 mm), you will need to adjust the latch board-U, L. Go to step 3 and follow all steps in order.
ADJUST THE LATCH AND SWITCH CLOSINGS -
Loosen the two screws holding the plastic latch board as shown.
-
With the oven door closed tightly, move the latch board upward toward the top of the oven and/or away from the door latch until the gaps are less than 1/64″ (0.5 mm).
Hold the latch board tightly in this position until you check the sequence of the switches in steps 5 and 6.
TEST THE LATCH AND SWITCH SEQUENCE -
Open the oven door slowly. Watch the door latch, the Primary Switch. Release Rod and Lever on the switches to make sure they are zero to the body of the switches in the following sequence:
- Primary Interlock Switch
- Secondary Interlock Switch
- Interlock Monitor Switch
Adjust the latch board until the switches operate in this sequence. See Steps 3 and 4.
-
Close the oven door slowly and be sure it is tightly closed. Watch the three switches to make sure they are zero to the body of the switches in the following sequence:
- Interlock Monitor Switch
- Primary Interlock Switch
- Secondary Interlock Switch
NOTE: The Interlock Monitor Switch is an added safety check on the Primary and Secondary Interlock Switches. If the Primary and Secondary Interlock Switches allow the oven to operate with the door open, the Monitor Switch will blow the fuse.
-
When you achieve the proper sequence of switches in Steps 5 and 6, tighten the latch board screws at that point.
TEST THE MICROWAVE ENERGY LEAKAGE -
Using a survey meter, make sure the microwave energy is below 5 mW/cm. sq.
PRECAUTIONS ON INSTALLATION
(Figure 2)
A. Plug the power supply cord into a 120 V AC, 60 Hz, single-phase power
source with a capacity of at least 15 amperes.
B. Since the unit weights about 26 lbs, be sure to place it on a sturdy
and flat surface.
C. Avoid placing the unit in a location where there is direct heat or
splashing water.
D. Place the unit as far away as possible from TV, radio, etc. to prevent
interference.
CAUTION
This unit is equipped with a 3-prong plug for your safety. If the wall outlet is a grounded 3-hole type, the unit will be grounded automatically.
Properly Polarized and Grounded Outlet
Three-Pronged{Grounding) Plug

GENERAL PRECAUTIONS IN USE
A. Never operate the unit when it is empty. Operating the oven with no
load may shorten the life of the magnetron.
Whenever cooking dry foods (dried fish, bread, etc.) or a small amount of
food, be sure to put a glass of water into the cooking compartment. The
turntable tray may become hot after operating, be careful when touching it.
B. Aluminum foil should be avoided because it will disrupt cooking and
may cause arcing. However, small pieces may be used to cover some parts of
food to slow the cooking. Any aluminum foil used should never be closer than
2.5 cm to any side wall of the oven.
TRIAL OPERATION
After installation, the following sequences and results should be checked carefully.
A. Put a container filled with water (about 1 liter) into the oven, and
close the door tightly.
B. Touch the STOP/CLEAR and the COOK TIME keys. “0” appears in the
display window.
C. Set cooking time for 10 minutes by touching “1” and then “0” three
times. “1000” appears in the display window.
D. Touch the START key. Make sure the cavity light comes on. The unit
will begin cooking and the display window will show the time counting down by
seconds.
E. After about 5 minutes, make sure the primary interlock switch, the
secondary interlock switch and the interlock monitor and oven lamp switch
operate properly by opening and closing the door several times. Touch the
START key each time the door is closed.
F. Continue operating the unit. Two short and a long beep sound signal is
heard when the time is up. The unit will shut off automatically.
G. Confirm the water is hot.
H. Finally, measure the output power according to “POWER OUTPUT
MEASUREMENT” on page 12.
