NOTE
The power output specification, 1100W. on this model is
measured with IEC measurement. The power output is
measured with two (2) liters water is equivalent to 1100W.
in measurement with IEC, when measured with the following
power output.
(1) Fill two beakers (glass or plastic) with each one liter of
tap water (about 20°C) and measure the water temperature.
(Use a thermometer with a 1/10 degree gauge).
(2) Place the beakers side by side in the center of the glass tray.
(3) Close the door, set the “TIME” for two minutes. (“200” in
the display window). Touch the “START” key and heat
the water exactly for two minutes.
(4) Take the beakers out, immediately stir the water and
measure the water temperature respectively.
(5) Calculate the temperature rise of water in each beaker.
Then calculate the average value of two temperature rises.
Output power can be calculated by the equation :
Power Output (W) = 70 x
∆
t
Where
∆
t is an average temperature rise in degrees
Centigrade.
(6) Power Output shall be in the following range :

889W
Maximum
29.3°F (16.3°C)
1141W
(7) Power Output is affected by the line voltage under load.
For correct Power Output measurement, the line voltage
under load must be 120±1 volts.

(1) Before the power is applied :
(a) Open and close door several times to make sure the
primary interlock switch, the interlock monitor switch
and the door sensing switch operate properly.
(Listen for the clicking sound from the switches).
Make sure the interlock monitor switch closes after
the primary interlock switch is opens when the door
is opened. (See pages 1 and 6).
(b) Make sure the perforated screen and the choke die-
lectric of the door are correctly mounted.
(2) After the power is applied :
(a) Open and close the door to see if the interlock mech-
anism operates properly.
(b) Check microwave energy leakage with a leakage
detector and confirm the energy leakage should be
no greater than 4mW/cm
2
to allow for measurement
uncertainty.
(3) Do not operate the unit until it is completely repaired,
if any of the following conditions exists :
(a) Door does not close firmly against the cavity front.
(b) The hinge is broken.
(c) The choke dielectric or the door seal is damaged.
(d) The door is bent or warped, or there is any other
visible damage to the oven that may cause microwave
energy leakage.
NOTE :
Always keep the seal clean.

(e) Make sure that there are no defective parts in the
interlock mechanism.
(f) Make sure there are no defective parts in the
microwave generating and transmission assembly.
(especially waveguide).
(4) The following items should be checked after the unit
is repaired :
(a) The interlock monitor switch is connected correctly
and firmly.
(b) The magnetron gasket on the magnetron is properly
positioned.
(c) Waveguide and oven cavity are intact (no leakage of
microwave energy).
(d) The door can be properly closed and the safety
switches work properly.
(e) The oven must be stopped when the door is opened
or the time is up.
The oven must not be operated with any of the above
