Swissnetsi3 years ago000Hello all How often do the evaporator cassettes need to be changed, how many times can they be cleaned without replacing? Thank you for the feedback ThomasShow in original language (German)arno3 years ago000Change every 2-3 months, 3 months seems good enough to me. No cleaning. The silver element must be changed 1x per year.Show in original language (German)Comment
