Frequently Asked Questions - TK-AB50 PANASONIC

What should I do if I won't use the unit for a prolonged period?

Remove the cartridge, place it in a plastic bag, remove air, and store in the refrigerator. Disconnect the power plug. Before reuse, install cartridge, reconnect power, and run water for about 3 minutes. If unused for over a month, replace the cartridge.

Can I use groundwater?

Groundwater may not be usable due to quality variations. Tap water is recommended.

What is the white powder deposited in kettles?

It is calcium from the water. It is harmless. To remove, use citric acid (50 g per liter of water) and soak for 2-3 days, then rinse.

Should I leave the power on when not in use?

Yes, leave the power on to allow automatic electrode cleaning and correct cartridge life calculation. Standby power consumption is about 1 W.

Why is the pH level harder to increase compared to initial use?

This may be due to calcium sediment on the electrodes, reducing electrolytic capacity.

What kind of water should babies drink?

Start with purified water. As babies are weaned, gradually introduce alkaline ion water at the Low setting.

What should I do if I get diarrhea or rash after drinking alkaline ion water?

Stop drinking and consult a doctor. Inform the doctor that the water contains more minerals and is alkaline (pH 8-9 at new user setting).

Why does alkaline ion water sometimes have white bubbles?

The bubbles are air mixed in during electrolysis or hydrogen gas. This is normal, especially after installation or cartridge replacement.

How much calcium is in alkaline ion water?

Due to electrolysis, there are 20% to 30% more calcium ions than in the source water.

What does it mean when the filter replacement light flashes?

It indicates the cartridge is blocked or water pressure is low. First, try opening the water stop valve. If the light stays on (red), replace the cartridge.

The acidic water with pH level of 4.0 or below will show the same color.

Main ingredients: Ethanol/methyl red/bromothymol blue/phenolphthalein

□ Installation instructions

- Please check whether all the items in the final check table (P.EN26 in installation instructions) have been ticked (finished).

Installation 2 Check after installation

To exhaust the air in the main unit, the purified water shall be drained for 5 minutes.

To use the Alkaline Ionizer (P.EN16)

• The blue water signal indicator will flash for about 20 \~ 30 seconds and then stabilize at on state.
• If the air in the main unit is not completely exhausted, the water flow will not be smooth.

Line drawing of a kitchen sink with faucet and water pump (no text or symbols)

Installation 3 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.”

■ About pH level standard

• Check whether the alkaline ion water has reached to the range of "pH level standard".
• Please regularly use the pH test liquid to measure the level.
  (Standard check frequency: more than 1 time every month)

Water quality	Weak acidic	Alkaline ion water			Purified water
		Low Middle High
pH level standard	5 ~ 6.5 8 ~	9 8.5 ~ 9.5		Between 9 ~ 10	Water that is not electrolyzed

EN12

Installation 3 Measure and adjust the pH level of water

Procedure for measurement

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

Measure with Alkaline ion water (High) and weak acidic 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.

Installation

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.

4 Under the enough light, compare the result with the pH Chart.

The color of the test water will change as time passes.

Compare its pH level against the pH Chart right away.

English

Notes

• If a new cartridge is used (for about 1 week), the pH level will be slightly higher, but this phenomenon is normal.
• For the determination of raw water, the color of test water will be different from that in the pH Chart due to the influence of the various ingredients in the water.
  ● Use of commercial litmus paper will lead to incorrect test.

EN13

Installation 3 Measure and adjust the pH level of water (continued)

When is adjustment necessary?

When the measurement results are beyond the range of "pH level standard", adjustment shall be made. After the completion of adjustment, the pH level shall be measured again.

3 How to turn off water

① Press Water Stop/Flow again to turn off water running.

● The water run through will not stop right away (requires about 1 second). (To avoid great abrupt force applied to the piping)

- When using “weak acidic” function, the weak acidic water in the main unit will be drained from the main spout and drain outlet for about 5 seconds; afterwards, the water outflow will stop. (Automatic cleaning begins.) (P.EN22)

- After water outflow stops, return to the "purified water" state. ( If the "priority mode of alkaline ion water" is set as follows, it will return to the "alkaline ion water (Low) to (High)" mode chosen before the use of "weak acidic" mode.)

Water signal indicator

Blue

In preparation: Flash (about 15 seconds) Drinkable: The light is on

- Do not drink the water that flows out of the main spout when the water signal indicator is flashing. (The water is not applicable for drinking.)

Red

In preparation: Flash (15 seconds) Ready to use: The light is on

The buzzer during water flowing can be muted.
- Please conduct after water flowing is stopped.
- Please press Weak Acidic until there is a buzzer of "Pi-" (about 3 seconds).
- Please press Weak Acid again until there are the buzzer of "Pi, Pi, Pi, Pi" (about 3 seconds), and the function of buzzer is enabled again.

As for the priority mode of alkaline ion water

When the water stops after using "purified water" or "weak acidic water", the water quality will recover to the alkaline ion water chosen by the last time. (Please conduct after stopping water outflow.)

→Press Purified (about 3 seconds), then it will in the "priority mode of alkaline ion water". (The original setup will be recovered after pressing again for about 3 seconds.)

Adjustment of water pressure

When the water pressure is relatively high

(Please tighten the water stop valve a little bit.) To maintain the operation of normal functions, please adjust the water flow to about 1 cup of water (about 200 ml) per 3 seconds \~ 6 seconds. (So the filter flow is about 2 L \~ 4 L per minute.)

- When the water pressure is relatively low

- When the cartridge is quite new and it takes more than 6 seconds to fill one cup of water even if the water stop valve is completely opened, the water pressure may be too low (lower than 100kPa ), and the filter replacement light (red) will flash.

- If the water stop valve is too tight, the water signal indicator (blue) may be flashing rather than light up. Under this condition, the filter replacement light (red) may flash when the Alkaline Ionizer is in use, or the water flow at the main spout will stop.

→ Please open the water stop valve to increase water pressure.

EN17

Maintenance

Daily maintenance

Q&A

Question Answer
During use	What should I do when I'm not going to use the Main unit for a prolonged period (more than a week or so as a general guide)?	Remove the cartridge from the main unit, put it inside a plastic bag, remove the air from the bag and close it, and then store the bag in the refrigerator.Disconnect the power plug.Before re-using the Alkaline lonizer, install the cartridge, re-connect the power plug, and run water through the main unit for about 3 minutes.If you are not going to use the Alkaline lonizer for a month or more, the water inside the cartridge may have gone bad so it is recommended that you replace the cartridge.
	Can ground water be used?	Ground water may not be usable.Tap water is recommended because of significant differences in groundwater quality.
	What is the white powder that's deposited on the inside of the kettle and thermos flasks?	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.
	Do I leave the Alkaline lonizer's power on when I won't be using the Alkaline lonizer?	Leave the power on even while you're not using the Alkaline lonizer.One reason is so that the electrodes need to be automatically cleaned. Another reason is that the volume of all the water which has run through the Alkaline lonizer will not be totalized if the Alkaline lonizer is used with its power off and, as a result, the cartridge life will not be indicated correctly.The power consumption in the standby status is approximately 1 W.
	Compared with the early time of using, why the pH level is relatively difficult to increase now?	This may be caused by calcium sediment attached on the main unit, which reduces the electrolytic capacity of the Alkaline lonizer.
Alkaline ion water	What kind of water should babies be drinking?	We recommend you to start drinking from "purified water".As babies are weaned, start using alkaline ion water gradually with the "alkaline ion water (Low)" (drinking water for new user) setting. (Because infants have less developed stomachs and intestines than adults.)
	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 you've been drinking has more calcium, magnesium, sodium, potassium and other minerals than tap water.The water you've been drinking has an alkalinity with a pH level of 8 to 9 (at the New Users setting).
	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 else can I do with alkaline ion water besides drinking it?	You can use it for cooking, making rice, making tea or coffee just as you would with regular water. (P.EN16)
	When alkaline ion water is poured into a glass, white bubbles are formed.What is this about?	It means that air has become mixed in with the water inside the Alkaline lonizer or that the bubbles (hydrogen gas) were formed during the process of electrolysis.Lots of bubbles may be formed after the Alkaline lonizer has been installed or the cartridge replaced. There is no problem if you continue to use the Alkaline lonizer.The bubbles which form with acidic water are oxygen gas.
	Why does alkaline ion water sometimes appear shiny?The same is also sometimes true of purified water.	It is due to the precipitation of the components (mainly minerals) which are dissolved in the water.There is no problem if you drink the water, but if it bothers you, use the Alkaline lonizer at a reduced pH (ion concentration) level. The same kind of thing happens when the cartridge function has deteriorated, in which case replace the cartridge with a new one.
	What is the white stuff that floats in the water which is produced when 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.
	When I use alkaline ion water to cook rice, the rice becomes sticky. What can I do about this?	The rice may be sticky or yellow depending on the amount of water and the type of rice and rice cooker used. Either reduce the pH (hydrogen ion concentration) level of the alkaline ion water or use the Alkaline lonizer at the "Purified Water" setting.
	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 you are thinking of drinking has more calcium, magnesium, sodium, potassium and other minerals than tap water.The water you are thinking of drinking has an alkalinity with a pH level of 9.5 or so.

Q&A (continued)

Question Answer
About water discharge and weak acidic water	What kind of water is the one coming out from the drain outlet?	It is acidic if alkaline ion water is coming out from the main spout. It is alkaline if weak acidic water is coming out from the main spout.While the water signal indicator is blinking, the water coming out from the drain outlet differs in nature according to the water quality which was previously used. Water coming out from the drain outlet cannot be drunk.
	Is it ok to drink the acidic water by accident?	Please do not worry if the amount is little (about 1 cup).But do not drink any more. In addition, please seek for doctors for advice in case of discomfort.
	Compared with the total flow, what are the proportions of water that flows out from the main spout and drain outlet respectively?	The proportions are shown as follows.The water flows out from the main spout: about 80 %The water flows out from the drain outlet: about 20 %While confirming the measurement, please conduct at the state of water running through. The water should be filled into the same container in the same time period for comparison.In the beginning of use, the water flows out from the drain outlet will slightly increase.After the water outflow stops, there will be much water in the drain outlet due to the discharging of water in the main unit.When the water flow is relatively little, the water flows out from the drain outlet will increase slightly.
	Why the weak acidic water has an unpleasant smell?(Similar to the smell of swimming pool)	This is due to the hypochlorous acid contained in the weak acidic water. Please directly use at ease.Electrolytic reaction will make the chloride ions concentrate in weak acidic water, and hypochlorous acid will be generated as a result.
About hydrogen	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 outflow in one day. For heated situation, the hydrogen will evaporate at the same time of boiling.
	What is “pH adjustment mode”?	If a water source whose pH is hard to improve is used, you can increase the pH level by increasing electrolytic force. At the same time, the output of hydrogen will increase.
Cartridge	I want to replace the cartridge. What type should I use?	Use the cartridge with the TK-AS45C1 model number. (P.EN19, EN29)
	Why the filter replacement light is light up earlier than the replacing standard?	The filter replacement light will light up when the run through water volume or water run through pressure reduces. (P.EN19)Please confirm whether the water run through is insufficient due to low water pressure, or whether water pipe is damaged or squeezed. Additionally, due to the difference of water quality, the cartridge may be blocked before the specified time range. Please replace the cartridge in this case.
Others	What does a service life of 850 hours for the electrolyzer mean?	It means the accumulated electrolysis time (including cleaning time) of the electrolyzer of this Alkaline lonizer.If the average run through water volume is 30 L (3.2 L/min) in 1 day, it is equal to a service life of 10 years.When the electrolyzer is powered-on, the electrode plate will be consumed. When all the water quality indicator lights are light up, and there are 5 buzzer of “Pi-”, it means the service life of electrolyzer has been reached. Please contact a dealer or subordinate service station of Panasonic.

Troubleshooting (continued)

About dripping

Because the faucet uses “the method of installing switch in the water inlet” (as shown below), the following conditions will happen, but they are not abnormal phenomena.

● After pressing the water stop/flow button, the outlet water will not stop immediately, and the main spout and drain outlet will have dripping water.

(In case of low water temperature (in winter or when the underground water is used) or if the air enters into the inside of the cartridge, this phenomenon will be relatively easy to happen.

• During and after the automatic cleaning, the water residing in the faucet will flow out due to the bubbles generated by electrolysis.
• This phenomenon is also easy to happen when the water pressure is relatively high. At this time, please contact a dealer or subordinate service station of Panasonic.)

- Compared with the early use period, the amount of drip has increased.

( It is due to the clogging of the cartridge with the increase of the using time. If it is a concern, the cartridge can be replaced. The dripping phenomenon will recover to that in the early use period when the water outflow stops.)

Normal phenomenon

The so-called method of installing switch in the water inlet

In this method, the main unit (cartridge) bears water pressure only when water flows out.

Therefore, this method can avoid major damage caused by water leakage while the user is not at home.

Emergency treatment method

In case of abnormality (such as smell of burning, etc.), immediately stop the Alkaline Ionizer and unplug the power plug.

• If the Alkaline Ionizer is operated continuously under abnormal status, a fire or electric shocks may happen due to the phenomenon of heating, etc.
• Please contact a dealer or subordinate service station of Panasonic as soon as possible.
• When the power cord is damaged, it is required to be replaced by a dealer or subordinate service station of Panasonic to avoid hazard.
