ONE basic rule
There is one fundamental rule of water conditioning. NEVER OVERSIZE YOUR WATER CONDITIONER. Break this rule and you will have an unhappy customer.
How do you size correctly? Fundamentally in domestic situations, you just need to keep to this rule of thumb. If the customer will just use one shower at a time use the S15 if the customer will use 2-4 showers at a time use the S20.
IMPORTANT INFORMATION
Always earth the unit as it will not function properly unless this done. The unit uses zinc as a sacrificial anode. The zinc combines with the calcium bicarbonate (limescale) to produce zinc carbonate. This is the non-adhering lime that prevents the usual problems associated with limescale. The reaction produces a small charge and the bond will conduct this electrical charge to earth.
It is not uncommon to see a white powdery residue on taps and shower screens after installation. This is normal and is the non-adherent lime. It can easily be wiped away with a cloth. Householders may feel that this is a sign that the unit is not working, but it is simply residue of the lime in its new non-sticking format. Please inform the householder of this prior to installation. If they would like additional proof that the unit is functioning correctly, refer them to the “Kettle Test” Link.
