For power supply use the proper socket.
Do not connect too many loads to one outlet.
Fully insert the plug. Hold the plug itself, when
disconnecting it.
Do not operate the appliance with a damage cord or
plug, electric shock or fire may occur.
Unplug from outlet when not in use and before
cleaning. Allow to cool before putting on or taking
off parts.
Do not wash the body , cord or plug with water or pour
water directly into the body . Otherwise, electric
shock or malfunction may occur.
Unless the inner pot is in place, the switch can not
be turn on. If the switch is kept pressed forcibly ,
malfunction may occur.
If the switch is turned off prematurely , resulting in
cook failure, do not attempt to keep the switch
pressed forcibly . Malfunction may occur.
The possible cause of premature turning-off of the
switch is rice sticking to the bottom of inner pot or
the heater plate.
Keep the switch away from tableware.
Do not use in the following places.
“Wet floor, place where humidity is high”.
“Unstable place, place exposed to direct sunlight”.
“Place near heat sources such as a gas cooking
table”.
“On the low heat-resistant carpets and vinyl
table-cloth”.
Otherwise, electric shock, malfunction, or
deformation may occur.
Since it is very hot around the steam vent during or
immediately after cooking rice, keep your face and
hands away from the vent. Otherwise, you may burn
your face and hands.
Do not put the inner pot on other heat sources (e.g.
gas ring). Otherwise, it may be deformed, causing
rice cooking failure.
T ake care not to deform the body , inner pot and inner
lid. If they are deformed, rice cooking is disturbed.
Always keep clean the inner pot, heater plate, inner
lid and steam tube. If foreign matter such as grinds of
rice adhere to them, rice boiling and heat retention
may be adversely affected.
Do not put dish cloth on lid or on handle during
boiling. Otherwise, deformation and malfunction may
occur.
This model is for rice cooking and heat retention.
Do not use it as follows. Boiling-over or smell
permeation will occur.
“Heat retention of food (boiling rice, steamed rice with
red beans) which spoils quickly”.
“Cooking and heat retention of porridge and soup.
“Heat retention and addition of cool boiled rice”.
“Heat retention with plastic spoon put in the rice
cooker”.
Do not apply strong vibration and shock during
cooking rice. Thermostat error may occur , resulting
in cooking failure.
Steam may vent out from a clearance between the
body and lid, or the steam vent hole may peep.
This is not indication of trouble.
Be sure to put the steam tube and inner lid when
using. Otherwise cooking failure or poor heat
retention may occur.
Do not turn the rice cooker on without both rice and
water in the inner pot.

Center adjustment and confirmation of switch leg ass’y
1. For the center adjustment, align not with the thermostat rod, but with the hole of the outer pot.
(Carry out this work with particular strictness and care).
2. Adjust in such a manner that, when the switch leg ass’y held by hand as in Fig. 16 is lightly swung to the left
and right, it moves in a perfect symmetry with respect to the hole of the outer pot.
3. The switch button should be at the center of the panel hole.
Verification of Work and Function
1. Is there any part left uninstalled or any wrong wiring?
2. Is the center adjustment of the switch leg ass’y as specified?
3. Finally, energize for confirmation. (JAR RICE COOKER should be checked in the erected st ate.)
a. Is the state “WARM” achieved when the inner pot is detached, with the cooking switch set to “COOK”?
b. Does “COOK” and “WARM” indicator lamp not flicker , when the switch button is gently vibrated, with the
switch set to “WARM”?
c. Does “COOK” and “WARM” indicator lamp not flicker, when the switch button is gently vibrated up and
down, with the cooking switch set to “COOK”?
d. Is there no possibility that the cooking switch is turned ON, even when the switch button is depressed
without placing the inner pot?
e. Is the thermostat functioning perfectly?
f. Is the indicator lamp lit normarlly?
Measurement of Insulation Resistance
1. Insulation resistance
Should be more than 1 MΩ upon measurement by a 500V d.c. megger (Check before and immediately after
the temperature test).
2. Dielectric strength
Should be free from defects at 1000V a.c. for one min. with the cooking switch set to “COOK” take
measurements on the pins of the plug socket and also on each of the heater plate ass’y .
(T o be carried out after the insulation resist ance measurement which is taken immediately after the temperature
test.)
Stop to be measured
With the cooking switch set to “COOK”, take measurement on the blades of the plug socket and also on
each of the lid heater ass’y , heater plate ass’y and cord reel ass’y.
Basic requirement for cooking is to maintain the close contact of inner pot bottom with heater plate and
thermostat. As the JAR RICE COOKER is of direct heating type, when the temperature of inner pot bottom reaches
141oC to 149oC, the thermostat will operate to provide change-over to warm-keeping automatically.
Therefore, the cooker can be put in use in an excellent condition if the inner pot bottom is kept contact closely with
the heater plate and put in a stable state. It is the basic requirement for the direct heating type cooking. Accordingly ,
if the cooker is used under the unstable state of close contact, it will become the causes of early power
OFF, discoloration and deformation of heater plate or other troubles. Also, any deformed or
contaminant-deposited inner pot and heater plate may lead to early power OFF or other troubles. Further to the
above, this JAR RICE COOKER is so designed that the cooking switch will not be put in “COOK” position whenever
the inner pot is taken off or not set into the cooker before use, hence this point must be well noted when
adjusting the switch. Upon completion of repairing work, inspect the cooker as to the following points without fail.

In case satisfactory cooking of rice is not accomplished (excessively overdone or underdone), conduct the
temperature test in accordance with the following procedure.
Simplified Testing Method (Simulated Rice-Cooking)
1. Testing conditions
a. Power voltage 220V.
b. Fill inner pot with 180 ml. of water. (W ater temperature to be the same as ambient temperature.)
c. Ambient temperature to be 20 to 30oC.
d. JAR RICE COOKER to be sufficiently kept cooled (Cooker body temperature to be the same as ambient
temperature.)
e. Never fail to set the inner lid.
2. Testing procedure
a. Fill the inner pot with 180 ml. of water turn ON the cooking switch (for cooking purpose) to energize the
cooker and measure the time for cooking.
b. When steam comes out of the steam vent, open the lid and check the bubbling state on the bottom
of inner pot. (Check if the inner pot is allowed to be in close and stable contact with the heater plate ass’y.
Conduct checking within a short period of time so as not to influence over the operating time.)
c. Where the bubbling state is satisfactory, close the lid again and energize the cooker.
SIMPLIFIED TESTING METHOD
3. Judgement criteria
During the course of the simulated cooking with water conducted under the conditions as above, the rice cooker
if meeting the following requirements, will be considered acceptable.
a. If the bubbling state is such that bubbles occur evenly around the bottom of inner pot as shown in
Fig. 19(A), the inner pot is satisfactorily in contact with the heater plate ass’y . Where bubbles do not occur
more than 1/3 of the bottom periphery as shown in Fig. 19(B), contaminant deposits on the heater plate ass’y
or deformation or damage on the inner pot may be existing. (Though such contaminant deposits can be
removed by cleaning, the inner pot deformed to the extent hardly rectified should be replaced with new one.
The same applies to the heater plate ass’y deformed.)

Time
Practical Rice-Cooking Test
1. T esting conditions
a. Power voltage 220V .
b. Cooking 3 cups of rice. (Minimum)
c. Ambient temperature to be 20oC to 30oC.
d. Water to be maintained at standard level on the level gauge.
2. Judgement criteria
a. Individual lamp and switch to be turned as follows.
Cook indicator lamp goes ON.
Cooking switch OFF (after 20 to 30 minutes).
Warm indicator lamp goes ON.
b. Check the rice layer on the pot bottom for the overdone degree.
Light overdone layer-Normal.
Heavy overdone layer-Replace thermostat ass’y .
3. Measurement of Warm-Keeping T emperature
At the empty state of inner pot, insert a bar-type thermometer , 100oC in full-scale into the inner pot, set the
inner lid and lid, and put the cooking switch to “COOK” position. Af ter the cooker is energized for about
2 minutes manually turn the cooking switch only to “WARM” position to put the rice in warm-keeping state
for about an hour. In this case, the reading of warm-keeping temperature on the bar-type thermometer , if within
the following temperature range, will be acceptable.
Model
KS-R19S/ST
KS-R23S/ST
10 minutes (approx.)
b. When the lid is opened immediately after the cooking switch is turned OFF, no water should remain in the
inner pot or only a small amount of water (approximately 20 cc) is to remain in the recess around the outer
periphery of the bottom face of the inner pot.
c. Turn ON the power supply and ensure that the time required for the cooking switch to be turned OFF is
in the values as given in the table below .
Note : As this test is nothing but a simplified procedure, it should be noted that operating time varies depending
on different conditions such as difference between water temperature and ambient temperature, variations
in the quantity of water, etc.
Where any delicate non-conformance such as the operating time being slightly higher than that shown
in tables is observed as a result of the test, it is recommended to conduct practical rice-cooking test.

In case the warm-keeping temperature does not conform to the above temperature standard, replace the
warm-keeping TRS in accordance with the after-mentioned reparing procedure.
Warm-keeping temperature : 70oC to 76oC.
(Check this temperature immediately after opening the lid as the reading on the thermometer drops very quickly .)
Allow the bar-type thermometer to float above the pot bottom using a fragment of packing case, etc. so that the
thermometer does not come in direct contact with the inner pot.
It should be taken into account that the commercially available bar-type thermometer may give a measuring
error of one division or less.

PRECAUTIONS FOR W ARM-KEEPING TO GET T ASTY RICE
Help yourself to the tasty rice under the proper use and maintenance of JAR RICE COOKER
Major Trouble
Recommended Use and Maintenance
(Cautionary Instructions)
Before cooking, wash rice thoroughly.
Take precautions against specific rice (vitaminized rice, barley, extra-old
rice, etc.) having a peculiar and strong smell.
Refrain from using excessively turbid or smelling water as far as
practicable.
After steaming, unbind sufficiently the uneven or sticky mass of rice.
(For warm-keeping to the tasty rice, sufficient loosening and exposure
to air are needed.)
Be sure that latch button is kept engaged.
Use inner lid without fail.
Handle inner pot, inner lid, etc. carefully. (Any deformed part may cause
the cooker to be less tight and influence over the performance.)
Do not leave any spoon inside the pot nor put any napkin over the inner
pot when in use.
Do not add the separately cooked rice over the rice under warm-keeping.
Do not conduct warm-keeping of a small volume of rice.
For warm-keeping, necessarily cover the rice with the lid and switch ON.
If the rice smells even under normal cooker and operation as well as
proper temperature, then conduct sterilization and disinfection in
accordance with the following procedure since such smell appears to
be caused by microbes. (Provided that, a method under the following
Note : “In Case the Rice Smells” is recommended to the customers
because the following procedure may cause the fur and the like to
remain on the bottom of inner pot, making them uncomfortable.)
Pour approx. 200 c.c. of water into the inner pot, close the lid (together
with inner lid without fail), turn ON cooking switch, and keep the cooker
energized until the cooking switch has been turned OFF.
Thereafter, wash the inner pot, cartridge, etc. thoroughly with water and
wipe them up to be dried sufficiently, Wipe out any stains remaining on
the cooker body and lid completely with well-wrung cloth wetted with hot
water. (IMPORT ANT : NEVER WASH COOKER BODY WITH WA TER)
Refrain from using the cooker other than for rice cooking and warmkeeping purposes.
Note : In Case the Rice Smells.
*Immerse the inner pot and inner lid into hot water for 30 to 60 minutes. Also, wipe up the cooker
body and the underside of the inner lid thoroughly with well-wrung napkin wetted with hot water and
them sterilize them under direct sunlight for 2 to 3 hours.
