Before Replacing the Cartridge (continued)
Even if U25 or U26 is not displayed, replace the cartridge when:

 The water has an unpleasant odor or taste (this means that the cartridge's ability to fi lter out these
impurities has deteriorated).
 The period of time (about 1 year) that serves as a general guideline for when to replace the
cartridge has passed.

Inside the cartridge is a hollow fi ber membrane fi lter for removing microscopic dirt. The cartridge's life
will be shortened when the Alkaline Ionizer is used with a quality of water containing many clogging
substances.

Note
 The volume of water coming out of the Alkaline Ionizer may be reduced when:
 The water temperature is low (because the water does not run through the cartridge so easily).
 The Alkaline Ionizer is used in areas where the water pressure is low (under 70 kPa).
 The pressure of the tap water has dropped because of the demand for tap water in the area concerned.
 Immediately after a period when the water supply was shut off such as during plumbing work.
