How should a Detox Dechlorinator be installed?
The ideal is to install it vertically. This way it ensures that all water is evenly distributed. The units can be installed horizontally, but vertical mounting is best.

Should the Detox Dechlorinator be flushed before use?
Yes, run the unit until the water is clear and free of dust and carbon particles.
What flow rate should the Detox Dechlorinator be at?
The ideal is four litres per minute or less. Use a measuring jug, and make sure that it takes over 15 seconds to fill one litre. Any more and it is too much.
