Use a brush and vacuum cleaner for the cleaning process –the best method is to blow the
condenser with compressed air. Do not use hard or sharp objects which might damage or
destroy the condenser or the display case during cleaning. Apply the cleaning in regular
intervals (minimally once per month). The manufacturer/seller will not be responsible for any
damage resulting from unqualified handling. The manufacturer/seller is also not responsible
