320 filters manufactured after 2006, whether on gravity-fed or
The kit includes a control box which connects up to an automated
waste valve, airpump control box and an automatic inlet slide plate
(for gravity fed models only). Once installed and connected to your
pond pump and mains power the system will carry out cleaning
cycles at timed intervals or when pressing the manual clean button.
The Nexus Automatic System will control the cleaning cycle fully automatically. Cleaning is done on a timer, which is factory set to clean once every 3 days, however, this is easily adjustable to fit in with your pond requirements. The Nexus Automatic System will run a cleaning cycle which lasts approximately 10 minutes.
