Page 20: Operation
OPERATION The Nexus Automatic System will control the cleaning cycle fully automatically. During the cleaning cycle, water is flushed to waste, this will mean that unless the water in your pond is topped up, the water level will go down. We recommend that an automatic top up system be added to your installation to allow for this. -
Page 21: Cleaning Principles
CLEANING PRINCIPLES The generally accepted practice is that when you keep ornamental fish, whether in a pond or in an aquarium, to keep the water fresh, 10% of the volume of the water in the pond/aquarium should be changed on a weekly basis. With this in mind, we recommend that you set your Nexus Automatic system to run a cleaning cycle so as to exchange water in line with this. -
Page 22: Installing Non-Return Valves
In certain circumstances, depending on your proposed set-up, a non-return valve should be fitted after the pump. This is to prevent water siphoning back from the pond when the waste valve is in an open position. Order a 1½” non-return valve from Evolution Aqua quoting part number: K25-50-100 NON-RETURN VALVE ON PUMP FED INSTALLATIONS In order to maintain the water level in the filter, the PUMP-FED installation requires the non-return valve provided to be fitted after the pump and before the filter. -
