QUICK TEMP MODE
This function heats the water to the selected Keep Warm temperature without reaching a boil. The water will reach the
selected Keep Warm temperature quicker than the regular Boil mode. Other benefits include reduced steam and
reduced energy use. Use this mode when dechlorination is not necessary, such as when using bottled or purified water.
While the water is heating,
press the [qS ] button to
select the Quick Temp mode.
You cannot activate Quick Temp mode while
the product is set at 208°F Keep Warm mode.
Each press o f the REBOIL/QUICK
TEMP button changes the b oil
mode.
Regular Boil mode (Default)
Quick Temp mode
Holding the REBOIL/QUICK TEMP button for
more than 3 seconds activates Citric Acid

After reaching the
selected temperature, it
will automatically switch
to Keep Warm.
A melody sounds, the Boil light turns off
and the KEEP WARM light turns on.
160°F Keep Warm mode:
•Once the water temperature
reaches about 175°F (80°C), it will
switch to Keep Warm at 160°F
(70°C). Length of time for the
water temperature to reach 160°F
after heating up is approx. 30
minutes. (At a room temperature
of 73°F / 23°C with the Inner
Container filled to the Maximum
Water Level Line.)
•After the KEEP WARM light stops
blinking, it will switch to Keep
Warm mode.
•You cannot select 208°F Keep Warm mode while Quick Temp mode is
activated.
•There may be a lingering chlorine smell if tap water is used while Quick Temp
mode is activated. If this is an issue, use the regular Boil mode instead.
•Depending on the room temperature and amount of water the actual water
temperature after heating may differ from that shown on the Display.
•Depending on the temperature of the room and water, and atmospheric
pressure, some steam may be produced.
•The Quick Temp mode may be canceled if the Power Cord is detached. Set to
the desired mode again.
•The product begins the Regular Boil mode when water is added. Activate the
QUICK TEMP mode again.

•Water may not dispense smoothly just after boiling
has completed. In this case, wait for a short period of
time before dispensing hot water again.

button to dispense
hot water.
You can use the Café
Drip Dispensing mode for

•If using a cone filter placed directly on a cup, be
careful not to let it fall inside the cup while brewing.
•The first cup of water may not be hot enough just after
boiling has completed, or when you have not
dispensed water for a while. Discard a cup of hot
water before brewing.
•If the cup or other container that you use is cold, the
hot water may cool quickly. To prevent this, warm the
container before use.

•B e careful not to lose these screws.
©Remove the Inner Lid Gasket which is installed on the
Inner Lid.
A fte r rem oving the Inner Lid, check the plastic part of
the Upper Lid fo r abnorm alities.
-Hf this part is discolored or if it feels rough to the touch,
replace it (there will be a fee for this).

indicated "EMPTY FROM HERE."
(Please take precautions not to splash water
on the Hinge.)
When disposing hot water:
•Take precaution with the hot water and
steam. You may scald yourself.
•Take precaution as hot water may drip
from the Spout, causing scalds.
4
To rinse, fill the Inner Container with
water. Boil and dispense about a cup of
hot water to rinse out the Spout, allow to
cool, then dispose the remaining water.
To cancel the Citric Acid Cleaning at any time,
unplug the Power Plug for more than 5 seconds.
r
•Repeated citric acid cleaning may be
necessary for hard-to-remove residues or
if water does not dispense smoothly.
• I f mineral or alkaline ionized water is
used, calcium tends to build up on the
surface of the Inner Container. If scale
accumulates on the Inner Container or the
Filter, boiling may become louder than
usual and water may not dispense
smoothly. Frequent cleaning is
recommended when using mineral or
alkaline ionized water.
REPLACEMENT PARTS
•Replacement parts may be available for an additional
charge. Please replace damaged parts only with new parts.
•When replacing parts, please record the model number and
part name beforehand. Parts can be purchased through

Q&A ON PRODUCT USE
Is it okay to use the product for
heating liquids other than water?
^
^
Do not fill the product with any liquid other than water. It may cause
malfunction, or may overflow and cause scalding.
► pg-3
Does the water need to be
changed every day?
^
W
To prevent odor and scale build-up, please change the water at least once
a day.
y pg-10
Is it okay to use mineral water
or alkaline ionized water?
^
r
Yes. However, when mineral or alkaline ionized water is used, a floating
residue may develop or milky white substance may form on the surface of
the Inner Container. This is due to the ingredients in the water and is
harmless to your health. Frequent cleaning is recommended.
^pg -9
pg.17 r
1 accidentally drank water while
performing the Citric Acid Cleaning.
Is this harmful to my health?
^
Please follow the instructions shown on the package of the citric acid
cleaner CD-K03E-JU.
Is it okay to leave the product
unattended while it is turned on?
^
W
It is safe to use the product unattended as it has an Automatic Shut-Off function
(power to the heater will be automatically turned off), which will be activated once it
is empty of water. However be careful not to repeat the boiling process without filling
the Inner Container with water, as the Nonstick Coating may discolor and peel.
