Evolution Aqua Nexus 220+ / 320+ Automatic Kit – Pump Fed

Continuing our long standing reputation for innovation, the Nexus Automatic System now enables Nexus owners to benefit from a fully automated cleaning cycle on their multi award winning Nexus filtration systems. Physically turning ball valves and manually switching pumps on and off will now be a thing of the past thanks to the Nexus Automatic System. All of the key processes that form the cleaning cycle are now controlled automatically with this easy to install kit.

Overview

The Nexus Automatic System can be installed on Nexus 220 and 320 filters manufactured after 2006, whether on gravity-fed or pump-fed installations. 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.

Cleaning Cycle

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.

Gravity Fed Cleaning Cycle

• Adjustable timer kicks in to start a cleaning cycle.
• Control box automatically switches circulating pump off.
• The water level in the Nexus equalises.
• Inlet valve closes whilst at the same time air is diverted from the outer bio chamber to the EAZY to clean the media.
• After the media has been cleaned, the waste valve opens.
• EAZY is drained to waste and inlet valve opens for a final flush of the EAZY.
• The waste valve closes.
• Air is diverted back from the EAZY to the bio chamber.
• Circulating pump is switched back on.
• Nexus returns to filtration mode.
