Amount of generated
water and purified water
has decreased.
Abnormal odor occurs.
Filter life has expired.
⇒
Replace the filter.
This is a solid created by a calcium reaction.
⇒
It is not harmful if it is ingested.
White floating matter
appears.
Red water (red rust, etc.,
mixed water) comes out.
Rust from the water pipe or turbidity after water supply work is coming
out. (Do not drink.)
⇒
Set the water selection lever to the
“Raw” side, and flow water until red water does not come out.
Generated water
“Alkaline ionized water”
does not show blue
or dark blue even when
tested with pH test liquid.
This is the influence of carbonic acid in tap water. Electrolysis was
performed. Check for carbonic acid by the following methods.
(1) Add alkaline ionized water of pH 9.0 to a cup.
(2) Add two droplets of pH test liquid to the dedicated cup.
(3) Add the alkaline ionized water which was taken in the cup
up to the scale on the dedicated cup. If the water becomes
blue or dark blue and then immediately discolors to green
or yellow, it contains carbonic acid.

Remove contaminants adhered to the metal mesh in the corporation
stop.

Is the filter clogged?
⇒
Clogging timing may greatly depend on water quality (turbidity,
iron rust) of tap water.
Replace the filter.

Has salt solidified in the salt case?
⇒
Wash out the solidified salt and add new salt.
“Sanitized water” cannot
be generated.

When “alkaline ionized
water” is received by
a cup, glittery floating
matter can be seen or
dark brown or black
precipitates and floating
matter can be seen.
Because of high pH value, components (mainly mineral) which are
dissolved in water become hydroxide. (It is not harmful if it is ingested.)
⇒
Decrease the pH value to use.

This is the influence of chlorine contained in sanitized water.
⇒
If there is a chlorine odor, this means that sanitized water has
been generated.
pH test liquid dose not
show orange with
“Sanitized water”.
