McAlpine SCA-RE Scale Defender Refill Cartridges (X2)

The dosing filter capacity is a maximum of 40,000 litres and should be replaced when exhausted to maintain the effectiveness of protection. Inside the dosing filter is a small red ball. When the ball is at the bottom of the dosing filter, the filter should be replaced. We recommend checking the filter every month or so. The pre-filter can be checked and cleaned periodically, or upon changing the dosing cartridge to ensure the flow rate through the system is not reduced. This may vary depending upon your water conditions.

McAlpine SCA-STA Scale Defender Starter Pack

How the system works The Scale Defender water system is designed to reduce the damage that sediment can cause to household taps and appliances. This level of dosage complies with the British Standard BS EN 1212 and EC drinking water standard (NENEN 1212). The dosing cartridge adds food grade sodium phosphate to the incoming water supply at a maximum concentration of 5 parts per million, these additives coat the scale within the water making it more difficult for the scale to attach itself to surfaces. Whilst the scale is not physically removed, this gives the water working properties similar to that of softer water improving the effectiveness of detergents and preventing scale build up, leading to improvements in heating system efficiency.  Other benefits include reduction of scale effects on showerheads, glasses, sanitary fittings and heating elements in washing machines and boilers. Scale Defender does not affect your natural ingestion of calcium via your water supply. The installation should be periodically checked for damage. If the property is left unattended for a prolonged period, we recommend isolating the water supply. When returning, Scale Defender should be flushed through as recommended by your water supplier.
