It occurs when calcium mineral contained in Alkaline Ionized Water is precipitated. As higher pH is and as well ionization process, it may happen while it does not appear in case of simply purified water or pH 7.5. You may clearly find it out if you prepare a bottle of Alkaline Ionized Water and another bottle of simply purified water and place them in a fridge. It is not impurities nor slime, so you don’t have to worry about it.

You may find a small button (reset button) on filter. If pressing it with the power on, the filter usage will be changed to ‘0’. For detail information, please refer to the video clip on filter exchange.

ER-1 : It appears when the input voltage is lower as much as 10% of the rated voltage

- Trouble shooting: turn it off and contact out A/S service center. Even after turning it off, you may    enjoy drinking water.

ER-2 : It appears when the input voltage is higher as much as 10% of the rated voltage

- Trouble shooting: turn it off and contact out A/S service center. Even after turning it off, you may    enjoy drinking water.

ER-3 : Message when electrolytic cell is overheated

- Trouble shooting: it may appear when minerals increases if using the system for a long time or    using underground water. Try to use it again in an hour after turning it off. If it does not disappear,    please contact our A/S service center.

ER-0/OFF : Message when the input volume is 3L/minute(excessive volume)

- Trouble shooting: control the flow by using valves.

ER-7 : Message appearing when self-cleaning

- Trouble shooting: please wait until the self-cleaning process is finished.

ER-8 : Message when a fake filter is installed

- Trouble Shooting : Need to replace with a genuine filter designated by Biontech Co., Ltd.

Condensed water may be generated inside the system depending on the ambient temperature or humidity. Please contact our A/S service center if leakage is excessive.

Self - Cleaning Mode is adopted to maintain the electrolytic cell optimal, in which the polarities of the cell is exchanged for 30 seconds. Do not drink it because it may contain scales that had been inserted in the cell.

The filter used for Biontech Alkaline Water Ionizer contains activated carbon (charcoal) that is made by burning and compressing coconut, absorbing smells and viruses. New filter contains dried activated carbon, so it is necessary to allow water flow for 5 ~ 10 minutes (turning it off and loose a valve) to eliminate dust; if omitting the process or lacking proper volume of water allowed, it may discharge dust. Such impurities may be discharge even in a certain time after exchanging filters. It is normally the cases that happen when lacking the water volume. Since it is vegetable based material, it does not harm your body but you’d better allow water flow for a time.

Biontech Co., Ltd. Alkaline Water Ionizer adopts filter addition flow system, using the method to measure filter usage depending on the volume of water used accumulatively. Depending on models, it may be used until it indicates ‘99’, ‘999’ or ‘9999’ and if the time to exchange filters, it displays ‘Please exchange your filter’. Filter is expendable, so it is not recommended to use it for a year or longer.

First, turn it off, separate a filter from the frame, cover it with plastic and place it in a fridge. To resume it, reassemble the filter, allow water for 3 minutes. Eliminate water completely, wrap it to prevent any dust from being inserted and store it in a dry place

Water purifier is normally used to filter impurities while Alkaline Water Ionizer, a kind of medical device, primarily purifies water using a compressive filter and supplies Alkaline Ionized Water for drinking or Acidic Ionized Water for washing body. In short, Water Ionizer can both purify and ionize water. It is wise to choose the multi-functional water ionizer than water purifier.

In principle, use tap water but it is also allowed to use underground water if using a separate filter depending on water quality or cases. Please consult your sales dealer or installation technician.

The product provided by Biontech Co., Ltd is equipped with auto power off function to protect itself, depending on areas or water quality. Close a valve and use it again. If it occurs continuously, please contact our A/S service center.
