This machine has the function of automatic filer replacement reminder. (Please see
page 12) The recommended filter life is based on the average indexes of tap water in
various districts. If users' actual water quality and using frequency have a great
discrepancy with average index, actual filter life differs greatly from estimated time, such
as early clogging or invalidity of filters. The customer should arrange for replacement with
their local service center based on the machine's actual usage conditions.
