Install the filter between the membrane outlet and the tank inlet.
Connect the quick fittings, observing the flow direction on the housing (IN → OUT).
Open the supply, check for leaks and run the first water for a few minutes.
To test with the kit, add 4 drops to a water sample and compare the colour with the chart.
