What’s included & installation The integrated brushless pump and LED UV-C switch on when water is drawn and switch off when demand stops. The system can be left powered on to supply domestic outlets in a suitable single-storey house, cabin or outbuilding. Three standard 10-inch filtration stages treat sediment and other contaminants before the water reaches the LED UV-C unit. The powder-coated aluminium frame has integrated mounting holes, 623mm apart centre to centre. An accumulator port is built into the frame. An accumulator can be added where required; the accumulator itself is not supplied. For drinking water, pair the system with FinalStage RO. The Argonide NanoCeram® Filter Cartridge can also be purchased for Filter C. The system does not filter saltwater or brackish water. Water quality varies according to the source, storage conditions, filter configuration and system maintenance. We cannot guarantee a particular output quality in every installation.
