5. TESTING PROCEDURE
5.1 Bubbling test
Input the pan in the main body, lightly rotate the pan clockwise and counter clockwise to settle the pan on the
heating plate properly.
1. Fill water until center area of the pan bottom is dipped and close the lid. Then turn on the boiling switch.
5.2 Evaporation test
1. Check that bubbling is proper, open the lid and place a weight.
2. Fully cover 2 to 3 sheet of tissue paper (gauze is also applicable) on the pan bottom and continuously
flow electric current.
Note : To prevent plastic parts from deformation caused by steam, be sure to open the lid fully.
Note : To prevent tissue paper from floating because of bubbling, previously hole the paper.
3. Water on the pan bottom is completely evaporated to be empty. This timing is an follows :
Within 1 minute before the boiling switch is turned off.
Within 1 minute after the boiling switch is turned off.
Place a weight so that its gravity center may be aligned at the center
2. When it beings boiling to produce steam. Remove the lid immediately check the bubbling condition on
the pan bottom.
3. As show in the figture.
If it is improper, it may result from the insufficient contact between the pan bottom and heating plate.
Check the pan bottom and the heating plate for foreign material remainder. Clean off the foreign materials
or replace the parts.
Bubbles generate through out the circumference of the pan bottom...............................................Proper
Bubbles does not generate on more than one quater part of the pan bottom circumference..........Improper

5.3 Heat reserving test
The above conditions are proper.
1. Put approx. 1 liter of water and the thermometer [ repairing tool (mercury thermometer ASN-150H) ] in
the pan, close the lid and turn on the boiling switch.
2. When it beings boiling to generate steam turn off the boiling switch.
Within 69°C - 77°C .....................................Proper
If outside 69°C - 77°C, check TRS mounting for irregularity, if it is proper, replace warming heater.
If it is improper, check the contact between the pan bottom, the heating plate and the center thermostat.
Repair or replace if necessary.
3. Add water or keep the lid opened until the reading of the thermometer falls to approx. 70°C.
4. When it becomes approx. 70°C, close the lid. After the warming heater is activated for 1 hour or more,
check the heat reserving temperature.

5.4 Boiling control lever adjustment
Such a mechanical operation as center thermostat goes up and down is used to turn on and off the
micro-switch. Check and adjust this relationship as shown below.
The auxiliary lever presses the push-button.
(The heat reserving lamp come on).
To gain the above relationship, adjust the auxiliary lever by bending it with long nose pliers.
