About "Scale"
While you are using this unit, minerals
contained in the water (like calcium) can get
stuck on the inner comtainer or on the mesh
filter. This is called "scale", and it is harmless.
●
Milky-white gritty surface (caused by calcium)
●
White or glittering floating material
(crystals of minerals)
●
Discoloration in the finish like dark brown,
gray, or green areas
(metallic ion made on the fluororesin covering)
These are not discoloration or corrosion of
the inner container itself, nor are they flakes
from the fluororesin covering.
Mesh filter
When filter is clogged, water does not flow
smoothly.
* After cleaning the filter, be sure to
reattach it to the inner container.
Clean the filter with a brush.
When storing the unit
●
Dry it thoroughly.
●
Put it into a plastic bag and seal the bag.
