CAUTIONS FOR USE
Never share the wall outlet with other appliances.
Insert the plug into the wall outlet firmly and when disconnecting, hold the plug and pull it out without touching
the power cord.
In case the power cord is broken, it must be replaced by manufacturer or appointed service providers or
equivalent professionals to avoid any damages.
Do not immerse the set in water or sprinkling water on the heater plate.
Never push the cook switch when the inner pot with rice is not placed in, never insert any object into the
switch. It may cause a trouble.
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 the cooker on a wet floor, under direct sunlight or near the gas stove.
While cooking, do not put the rice cooker on or near combustible materials such as curtains or vinyl carpets.
During or immediately after cooking the areas near the steam vent hole are kept at high temperature.
Do not touch those areas to avoid burns.
Never connect the plug with your wet hand as it may be dangerous from electric leakage. Disconnect the plug
from the wall outlet when you do not use the rice cooker.
Keep the rice cooker out of the children’s reach, especially when cooking rice.
Do not opening the lid when during boiling because touched hot steam.
Do not use the inner pot with heater appliance such as a gas stove. The inner pot may be transformed and it
may cause poor cooking result.
Do not give strong vibration of impact during cooking. It may cause an irregular operation of thermostat to lead
to poor rice-cooker.
Always keep clean the flange part and the bottom of the inner pot, the heater plate and the inner lid, etc. so
that they do not accumulate rice grain or foreign matter.
Do not place a wiping cloth or the like on the lid or the handle during use.
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 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.
Do not give strong vibration or impact during cooking. It may cause an irregular operation of thermostat to lead
to poor rice cooking. 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.
Do not disassemble or repair the cooker by yourself. It may cause trouble such as a fire of electric shock.
Consult your nearest dealer.
Do not use metal spoon that can scratch the inner pot.
Do not use any other inner pot except the provided one.

Basic requirement for cooking is to maintain the close contact of inner pot bottom with heater plate and
thermostat. AstheJARRICECOOKERisofdirectheatingtype,whenthetemperatureofinnerpotbottomreaches
145oC to 155oC, the thermostat will operate to provide change-over to warm-keeping automatically.
Therefore,the cooker can beputin use in anexcellentcondition if theinnerpot bottom is keptcontactclosely with
theheaterplateandputina stable state. It is the basic requirement forthe direct heatingtype 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 cook 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.
INSPECTION AFTER ASSEMBLING
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 state.)
a. Is the state “WARM” achieved when the inner pot is detached, with the cook 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 cook switch set to “COOK”?
d. Is there no possibility that the cook 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 normally?

Measurement of Insulation Resistance
1. Insulation resistance
Should be more than 1 M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 cook switch set to “COOK” take
measurements on the pins of the plug socket and also on each of the heater plate ass’y and bottom cover.
(To be carried out after the insulation resistance measurement which is taken immediately after the
temperature test.)
Stop to be measured
With the cook switch set to “COOK”, take measurement on the blades of the plug socket and also on
each of the heater plate ass’y and cord reel ass’y.

2. Testing procedure
a. Fill the inner pot with 80 ml. of water turn ON the cook 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.
3. Judgment criteria
During the course of the simulated cooking with water conducted under the conditions as above, 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 containment 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 deformed.)
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 80 ml. of water. (Water 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.

Practical Rice-Cooking Test
1. Testing 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.
Cook 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 Temperature
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 cook switch to “COOK” position. After the cooker is energized for about
2 minutes manually turn the cook 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.
14
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. 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 varied
depending on different conditions such as difference between water temperature and ambient
temperature, variations in the quantity of water, etc. Where any delicate non-conference 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 repairing procedure.
Warm-keeping temperature : 68oC to 73oC.
(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 WARM-KEEPING TO GET TASTY RICE
Help yourself to the tasty rice under the proper use and maintenance of JAR RICE COOKER.
Smelling Dewing Sticking Drying
Discoloring
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 stick 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 or put any napkin over the inner
pot when in use.
Allow warm-keeping to be limited to 12 hours max.
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 upper lid
(together with inner lid without fail), turn ON cook switch, and keep
the cooker energized until the cook 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 outer lid completely with well-wrung cloth wetted
with hot water. (IMPORTANT : NEVER WASH COOKER BODY WITH
WATER).
Refrain from using the cooker outer than for rice cooking and warm-
keeping 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.
