Maintenance and replacement

To maintain full flow, we recommend rinsing the insert with a strong jet of water roughly every 14 days and treating it once a month with a cartridge filter cleaner that dissolves grease and organic deposits. The filter fabric ages over time, so it is advisable to replace the cartridge with a new one after about 12 months of operation. Timely replacement protects both the circulation and massage pumps against excessive wear.
