MICROWAVE MEASUREMENT PROCEDURE
A. Requirements:
1) Microwave leakage limit (Power density limit): The power density of microwave radiation emitted by a microwave oven
should not exceed 1mW/cm2 at any point 5cm or more from the external surface of the oven, measured prior to acquisition
by a purchaser, and thereafter (through the useful life of the oven), 5 mW/cm2 at any point 5cm or more from the external
surface of the oven.
2) Safety interlock switches:
Primary interlock relay switch shall prevent microwave radiation emission in excess of the requirement as above
mentioned. Secondary interlock relay and door sensing switch shall prevent microwave radiation emission in excess of
5 mW/cm2 at any point 5cm or more from the external surface of the oven.
B. Preparation for testing:
Before beginning the actual measurement of leakage, proceed as follows:
1) Make sure that the actual instrument is operating normally as specified in its instruction booklet.
Important:
Survey instruments that comply with the requirement for instrumentation as prescribed by the performance standard for
microwave ovens, 21 CFR 1030.10(c)(3)(i), must be used for testing.
2) Place the load of 275±15 ml (9.8 oz) of tap water initially at 20±5O C (68OF) in the center of the oven cavity.
The water container shall be a low form of 600 ml (20 oz) beaker with an inside diameter of approx. 8.5 cm (3-1/2 in.) and
made of an electrically nonconductive material such as glass or plastic.
The placing of this standard load in the oven is important not only to protect the oven, but also to insure that any leakage
is measured accurately.
3) Set the cooking control on Full Power Cooking Mode.
4) Close the drawer and select a cook cycle of several minutes. If the water begins to boil before the survey is completed,
replace it with 275 ml of cool water.
C. Leakage test:
Closed-drawer leakage test (microwave measurement):
1) Grasp the probe of the survey instrument and hold it perpendicular to the gap between the drawer and the body of the
oven.
2) Move the probe slowly, not faster than 1 in./sec. (2.5 cm/sec.) along the gap, watching for the maximum indication on the
meter.
3) Check for leakage at the drawer screen, sheet metal seams and other accessible positions where the continuity of the
metal has been breached (eg., around the switches, indicator, and vents).
While testing for leakage around the drawer, pull the drawer away from the front of the oven as far as is permitted by the
closed latch assembly.
4) Measure carefully at the point of highest leakage and make sure that the highest leakage is no greater than 4mW/cm2,
and that the primary interlock switch/secondary interlock relay does turn the oven OFF before any door movement.
NOTE: After servicing, record data on service invoice and microwave leakage report.

NORMAL INSTALLATION STEPS
ANTI-TIP BRACKET INSTALLATION INSTRUCTIONS
IMPORTANT SAFETY WARNING
To reduce the risk of tipping of the range, the range must be secured
to the floor by properly installed Anti-Tip bracket and screws packed
with the range. Failure to install the Anti-Tip bracket will allow the
range to tip over if excessive weight is placed on an open door or if
a child climbs upon it. Serious injury might result from spilled hot
liquids or from the range itself.
If range is ever moved to a different location, the Anti-Tip bracket
must also be moved and installed with the range. Instructions are
provided for installation in wood or cement fastened to either the floor
or wall. When installed to the wall, make sure that screws completely
penetrate dry wall and are secured in wood or metal. When fastening
to the floor or wall, be sure that screws do not penetrate electrical
wiring or plumbing.
Drill a 1/8-inch pilot hole where screws are to be located. If bracket
is to be mounted to the wall, drill pilot hole at an approximate 20
degree downward angle. If bracket is to be mounted to masonry or
ceramic floors, drill a 5/32-inch pilot hole 1 3/4-inches deep. The
screws provided may be used in wood or concrete material. Use a
5/16 -inch nut-driver or flat head screwdriver to secure the bracket
in place.

Level range by adjusting the (4) leveling legs with a wrench. Note:
A minimum clearance of 1/8-inch is required between the bottom
of the range and the leveling leg to allow room for the bracket. Use
a level to check your adjustments. Plug range into properly prepared
electrical receptacle or if hard wired, check that it was completed
properly. Check door condition for evenness and stability. Slide
range back into position.
Visually check that rear leveling leg is inserted into and fully secured
by the Anti-Tip bracket by looking underneath the range with a
flashlight and carefully attempt to tilt it forward.
Figure 15
Mark the floor or wall where left or right side of the range will be
located. If rear of range is against the wall or no further than 1 1/4 inches from wall when installed, you may use the wall or floor mount
method. If molding is installed and does not allow the bracket to fit
push against the wall, remove molding or mount bracket to the floor.
For wall mount, locate the bracket by placing the back edge of the
template against the rear wall and the side edge of template on the
mark made referencing the side of the range. Place bracket on top
of template and mark location of the screw holes in wall. If rear of
range is further than 1 1/4-inches from the wall when installed, attach
bracket to the floor. For floor mount, locate the bracket by placing
back edge of the template where the rear of the range will be located.
Mark the location of the screw holes, shown in template.

PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
The "Main PWB" of this model employs lead-free solder. This is indicated by the "LF" symbol printed on the PWB and
in the service manual. The suffix letter indicates the alloy type of the solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free wire solder
When repairing a PWB with the "LF" symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder
may result in cold soldered joints and damage to printed patterns.)
As the melting point of lead-free solder is approximately 40oC higher than tin/lead alloy solder, it is recommend that a
dedicated bit is used, and that the iron temperature is adjusted accordingly.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer wettability, (flow), to prevent damage to the
land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of
time. Remove the bit as soon as a good flow is achieved. The high content of tin in lead free solder will cause premature
corrosion of the bit. To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required.
Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their
characteristics, making good soldering more difficult. It will be necessary to clean and replace bits more often when using
lead-free solder. To reduce bit wear, care should be taken to clean the bit thoroughly after each use.

horizontal position of the latch hook should be adjusted
so that the monitor switch and drawer sensing switch are
activated with the drawer closed.
8. Secure the screws with washers firmly.
9. Check all of the switches operation. If any switch has not
activated fully, you will need to adjust the slide rail
attached to the Microwave cavity.
10.This is done by following the steps to remove the
"DRAWER/SLIDE RAIL REMOVAL" on page 42. After
you have removed the slide rails, loosen the "2" screws
holding the slide rail to the Microwave cavity and tilt the
front end up and the rear end down, then tighten the
screws (Fig. S-1).
11.Check and assure that the cap nuts on the Drawer
Support Angles are centered when passing through the
cavity face plate.
After adjustment, check the following.
1. In and out play of door remains less than 0.5mm when in
the latched position. First check upper position of latch
hook, pushing and pulling upper portion of drawer toward
the oven face. Then check lower portion of the latch hook,
pushing and pulling lower portion of the door toward the
oven face. Both results (play in the door) should be less
than 0.5mm.

After reassembly, do the following.
(A) Make sure that drawer sensing switch, secondary
interlock switch and monitor switch are operating
properly. (Refer to chapter "Test Procedures".)
(B) An approved microwave survey meter should be
used to assure compliance with proper microwave
radiation emission limitation standards.
Fig. D-3
After any servicing, make sure of the following :
1. Drawer latch heads smoothly catch latch hook through
latch holes and that latch head goes through center of
latch hole.
2. Deviation of door alignment from horizontal line of cavity
face plate is to be less than 1.0mm.
3. Drawer is positioned with its face pressed toward cavity
face plate.
4. Reassemble the unit and check for microwave leakage
around drawer with an approved microwave survey
meter. (Refer to Microwave Measurement Procedure.)
Fig. D-4
Note: The drawer on a microwave oven is designed to
act as an electronic seal preventing the leakage
of microwave energy from oven cavity during
cook cycle. This function does not require that
door be air-tight, moisture (condensation)-tight
or light-tight. Therefore, occasional appearance
of moisture, light or sensing of gentle warm air
movement around oven drawer is not abnormal
and do not of themselves indicate a leakage of
microwave energy from oven cavity.
