Maintenance Procedures

To ensure optimal performance, it is advisable that regular maintenance is performed. Typically the Jellyfish® requires a
service every 6 months, additionally as the Jellyfish® cartridges capture pollutants they will need to be replaced (expected
cartridge life is 2-5 years with a maximum cartridge life of 5 years).
