Frequently Asked Questions - TK-AS700 PANASONIC

What replacement cartridge does the TK-AS700 use?

Use model TK-AS700C-EX. Replace when the total flow reaches 6000 L or about once a year with typical use.

Can I drink the acidic water from the drain hose?

No, do not drink acidic water or any water from the drain hose. Only alkaline ion water and purified water from the main spout are drinkable. Weak acidic water can be used for skincare but not for drinking.

How should I store alkaline ion water?

Drink immediately or store in a clean sealed container. At room temperature, use within 1 day; in the refrigerator, use within 2 days. Avoid prolonged storage as chlorine is removed.

What is the recommended starting level for drinking alkaline water?

Start with Alkaline 1 (pH approx. 8.5). Drink 1-2 cups per day for two weeks to let your body adapt, then gradually move to Alkaline 2 and 3.

What should I do if the display shows 'Electrode cleaning'?

Wait for the automatic cleaning cycle to finish (approx. 10-50 seconds). Do not turn off the faucet or unplug the unit during cleaning. Water will come out from the drain hose—do not use it.

How do I adjust the pH level if it's too high or low?

Press the pH adjustment button and select 'Stronger' to increase pH or 'Milder' to decrease pH for alkaline or weak acidic water. Test with the supplied pH kit after adjustment.

Why is there white powder in my kettle after using alkaline water?

This is calcium from the water, harmless. Clean with citric acid solution (50 g in 1 L water) and rinse thoroughly.

Can I use the TK-AS700 with well water?

Only if the well water has passed a drinking water test. The unit is designed for qualified tap water; well water quality may affect pH adjustment and filter life.

What does the error code U26 mean?

U26 indicates that the cartridge has reached 6000 L capacity. Replace the cartridge immediately and reset the usage amount from the menu.

How do I clean the bypass selector filter?

Turn off water, loosen the nut, remove the bypass selector, take out the filter, and clean it with a soft toothbrush under running water. Reassemble and check for leaks.

Is it safe to take medicine with alkaline ion water?

No, use purified water for taking medicine. Alkaline water may interact with medications. Use alkaline ion water only for drinking, cooking, and other non-medication purposes.

Installation 6 Measure and adjust the pH level of water

After the Alkaline Ionizer has been installed or after it has not been used for a prolonged period (generally, a week or more), be absolutely sure to measure the pH level, and check that it is within the "pH standard" before using the Alkaline Ionizer. Remember to measure the pH level periodically (at least once a month).

Note

• What is the pH level (ion concentration)?

The pH level indicates the degree of alkalinity, neutrality or acidity of water (aqueous solutions), and stands for "hydrogen ion exponent."

Procedure for measurement

What to have ready: pH test kit (supplied accessory)

Measure with Alkaline 3 and weak acidic water respectively.

1 Put 2 drops of pH test liquid in to the test tube.

• The pH cannot be determined accurately any amount other than 2 drops.
• If the test water is placed before the pH test liquid is added, the two liquids may not be evenly mixed, leading to incorrect measurement.

2 Place the water generated by this machine in a regular cup.

- Flush water at least 10 seconds in order to obtain a stable pH level.

Illustration of a medical or laboratory device with tubing and a central container (no text or symbols visible)

3 Put the sample water into the test tube.

• If some of the test water is first collected in a glass and then poured into the test tube, it will be easier to align the level with the line inside the test tube.
• So long as the water inside the test tube is within 5 mm above or below the line, no problems will be posed in the pH level measurement: there is no need to adjust the level until it comes up to the exact level of the line.

Pour the water until it is near the line inside the test tube.

EN5)For the first 2 weeks, start drinking a small amount of water (one or two cups) with alkaline level 1.As you get used to alkaline ion water, gradually increase the alkaline level to 2 and next 3.(If you start drinking alkaline ion water with level 3, your health may be impaired.)
	Is it ok to take a medication with the alkaline ion water?	Use the Purified Water setting for the water to take your medicine with.You can use alkaline ion water for drinking, cooking and purposes other than taking medicine.
	What should I do if I get diarrhea or a rash after I start drinking alkaline ion water?	Stop drinking alkaline ion water, and consult a doctor.While consulting the doctor, say that:The alkaline ion water has more mineral contents (calcium, magnesium, sodium, potassium, etc.) than tap water.The water you have been drinking is alkaline with about pH 8 to 9. (in the case of alkaline ion water level 1)
	I have kidney trouble. Is it ok for me to drink alkaline ion water?	Consult a doctor before drinking alkaline ion water.While consulting the doctor, say that:The alkaline ion water has more mineral contents (calcium, magnesium, sodium, potassium, etc.) than tap water.The water you are thinking of drinking has an alkalinity with a pH level of 9.5 or so.

EN35

Q&A (continued)

Question Answer
Alkaline ion water	How long do the alkaline ion water and purifi ed water “keep”?	Use it within 1 day at room temperature.When alkaline ion water is produced, the chlorine (sterilizer) in the tap water is removed off, making it easier for bacteria to proliferate.Even when storing alkaline ion water in the refrigerator, keep it in a clean sealed container, and use it within 2 days.Also use weak acidic water within 2 days.
	Can I use alkaline ion water to make ice?	Use the ice made from alkaline ion water in the same you would with the ice made from tap water.If you store alkaline ion water in the tank of a refrigerator equipped with an automatic ice-making function, change the water within 2 days.
	White substances fl oat in water where ice made using alkaline ion water has melted.	These are minerals contained in the water.When water is frozen, the minerals solidify on the surfaces of the ice. There is no problem if you swallow the white bits.
	What else can I do with alkaline ion water besides drinking it?	You can use it for cooking, making rice, making tea just as you would with regular water. (P. EN25)
	When I use alkaline ion water to cook rice, the rice becomes sticky	Either reduce the pH level of the alkaline ion water or use Purified Water.The rice may be sticky or yellow depending on the amount of water and the type of rice and rice cooker used.
	How much calcium is contained in alkaline ion water?	Due to electrolysis, there are 20 % to 30 % more calcium ions in alkaline ion water than in the source water.
	What kind of water should infants or toddlers be drinking?	We recommend you to start drinking from purifi ed water.As babies are weaned, start using alkaline ion water gradually with the “Alkaline 1” setting.(Because infants have less developed stomachs and intestines than adults.)
Hydrogen	What is the hydrogen concentration displayed when alkaline ion water is used?	It is the amount of hydrogen (guideline) that occurs at the electrode while alkaline ion water is generated.
	How long will the produced hydrogen stay in the alkaline ion water?	The molecular of hydrogen is very small, therefore, it will reduce by a half in 2 days even if it is placed in a closed container, such as PET bottle.In non-closed container, all the hydrogen will outfl ow in one day.For heated situation, the hydrogen will evaporate at the same time of boiling.

EN36

Question Answer

Acidic water and water discharge	What kind of water is the one coming out from the drain outlet?	The type of water differs depending on the water coming out from the main spout. It is acidic water if alkaline ion water is coming out from the main spout. It is alkaline water if weak acidic water is coming out from the main spout. (When purified water is coming out from the main spout, no water comes out from the drain hose.) ( The quality of water coming out from the drain hose duringPreparation timechanges depending on the quality of water used last.) Water coming out from the drain outlet cannot be drunk.
	Drink the acidic water by accident	Please do not worry if the amount is little (about 1 cup). But do not drink any more. Please seek for doctors for advice in case of discomfort.
	What is pH of water coming out from the drain hose while alkaline ion water is used?	See the table on the right.	H of acidic water coming out from the drain hose while alkaline ion water is used
			Alkaline ion water	Alkaline 1 Alkaline 2 Alkaline	3 Alkaline 4
			PH level of the acidic water*	5.0~6.5 4.0~5.5 3.0~4.5	2.6~3.0
			* Differs depending on the water quality, flow rate and mode of tap water.
	What are the proportions of water that flows out from the main spout and drain outlet respectively?	See the table on the right.	Ratio of water from the main spout to water from the drain outlet
				Mode	Ratio of water from the main spout to water from the drain outlet
			Alkaline 1/2/3	Standard/Milder	16:1*
				Stronger	5:1
			Alkaline 4	Standard/Milder	5:1
				Stronger	5:1
			Weak acidic water	Standard/Milder	5:1
				Stronger
			Acidic water	Standard 1:5
			* When the amount of water flow is small (1.2 L/min): 5:1
Others	What does a service life of 850 hours for the electrolyzer mean?	It means that the cumulative total time (including cleaning time) that enables electrolysis in the electrolyzer is 850 hours. (equivalent to approx. seven years with use of 20 minutes a day) When the electrolyzer is powered-on, the electrode plate will be consumed. When replacement is necessary,H51is displayed.
	Can I disconnect the power plug when the product is not used?	Do not disconnect the power plug even while you're not using the Alkaline lonizer. This is to perform automatic electrode cleaning and display the guideline for cartridge replacement timing correctly. (Using purifi ed water with the power plug disconnected will not accumulate the usage time.)
	White powder is attached on the kettle or electric thermos fl ask.	It is the calcium from the water. There is no problem if you drink the water, but if it bothers you, clean the containers concerned. If the white powder is not removed by cleaning, obtain some citric acid from a pharmacy, mix 50 g with 1 liter of water, leave to soak in the containers for 2 or 3 days, and then rinse the deposit off. (Buy citric acid at a pharmacy.)
	Noise occurs when a radio is placed near the product.	Move the radio away from the Alkaline lonizer.

	Not much water comes out of the Alkaline lonizer after the cartridge has been replaced	Did you run water for approx. 3 to 4 minutes after replacement?(P. EN30)(It is necessary to remove the air inside the cartridge)
	Much water comes out	The water amount from the main spout varies depending on the kind of water and/or selection of the water quality even though the amount of source water stays constant.Maximum flow varies depending on the kind of water and/or selection of the water quality.
	Reduce water flow has become more likely to be displayed
	The water comes out from the main spout is warm	At an early stage of running of water, the water warmed by the room temperature or heat inside the Alkaline lonizer while water flow is stopped may come out.(This is not a malfunction. Allow the water to flowing before uses.)

Before Requesting a Repair Service (continued)

Problem Check point
Drain hose	Water is drained even after the faucet is closed.	Water inside the main unit is drained every after use.(P. EN27, EN31)
	Water is not drained while water other than purifi ed water is used.	Is the drain hose bent or fl attened?If water keeps running, it may cause malfunction. Also It can not electrolysis correctly.Rise ve is played? (P. EN27)
Sound and buzzer	A buzzer does not beep while weak acidic water or acidic water is used.	Has “Weak acidic buzzer” been set to OFF? (P. EN32)
	Sounds are heard from the unitafter the faucet has been turned off	A clicking sound may be heard from the main unit before water is drained.(This is not a malfunction)
Odor, taste, turbidness, and change in color	The water produced by the Alkaline lonizer has an odor or unpleasant taste or is turbid	Purifi cation performance of the cartridge is deteriorated.→ Replace the cartridge. (P. EN30)If an odor occurs within 2 to 3 months after the cartridge is replaced, the water discharge line or waste water line may be soiled.→ Press the Acidic button, and run weak acidic water for approx. 15 seconds.
	The smell at the beginning of use of water concerns me.	Since water is accumulated inside the main unit for 10 minutes after Alkaline level 1 to 3 and Purifi ed are used, there are rare cases where some people are sensitive to the smell of the main unit.→ If the smell concerns you, after a buzzer beeps, run water for a while before using.
	The weak acidic water has an odor	Electrolysis causes the chlorine ions in the water to collect in weak acidic water, forming hypochlorous acid.→ There’s no problem if you use it as is.
	White suspended matter is mixed in with the alkaline ion water	White floating matter is calcium deposited inside the main unit.Foam-like floating matter is the air inside the main unit or hydrogen foam generated during electrolysis.(There’s no problem if you use it as is.)This foam tends to be much generated after installation or cartridge replacement.In the case of weak acidic water, oxygen foam is generated.
	Alkaline ion water or purifi ed water looks shiny.	It is due to the precipitation of the components (mainly minerals) which are dissolved in the water.→ There’s no problem if you use it as is. But if it bothers you, use the Alkaline lonizer at a reduced pH (ion concentration) level.
