  • Please notify us of your returns via email: We will then provide you with an RMA number in advance.
  • Please enter this RMA number on the RMA document.
  • Please pack the goods properly (ideally in the original packaging) to preserve any warranty claims and avoid transport damage.
  • Please consider, that “wetted parts” (chlorine, acid, fragrance, water, etc.) which are returned have to be completely emptied and cleaned inside and out prior to shipment / provision and are therefore free of harmful substances (details see clearance declaration).
  • For the return of electronic components (control- and transformer boards…), please use the “ESD packaging” of the replacement parts received, if possible, or use equivalent packaging.
