Instructions for Replacing SC16S and SC32S whole house anti-scale cartridge
Product Codes: SC16S | SC32S | SC16TWO
Scale Centurion Softener Cartridge
This holds the special anti-scale media. Note the cartridge is only one third or so full. This is correct. (The media needs to move freely with the water in order to work properly.
(If you have a twin/combination type the housing you need to open would be the one on the right that says change every 24 months - The one on the left says “12 months”)
How to Replace Your Cartridge
1) Locate the correct housing ie with code SC16 or SC32
2) Turn off the water supply.
3) Take a bucket and place it under the filter housing to catch any water spillage.
4) Then press the red or black button on top of the housing unit (if you have one) to release pressure. Otherwise open up the cold water kitchen tap.
5) Remove the bottom housing from the head (Lefty loosey / righty tighty!)
6) Remove the Green topped “SC” cartridge
Discard the used cartridge (you can return it to us for recycling, later when it’s dried out).
7) Place the new cartridge in the housing - noting the top and bottom correctly. And make sure it is seated correctly in the bottom slot. Do not unscrew the Green lid on the cartridge.
Carefully guide the top of the cartridge up into the centering slot making sure you guide it carefully past any centralising prongs.
10) Close housing unit.
Once you are sure the cartridge is seated correctly inside the housing, tighten it by hand, then use the wrench to tighten it reasonably - don’t overtighten.
Optionally, before closing put some Vaseline around the large black rubber orings to lubricate them. You can also dab some on the screw threads to make it easier to open next time (but do not put Vaseline on the cartridges).
Note re Blue Head / White Bottom style Housings: A fully closed housing has a gap of 2mm to 3mm max between the lower blue nut and the blue top. You can get fairly close to this gap screwing it by hand. Then use the wrench to give it a final tightening. BUT if you need to use a lot of force with the wrench to achieve that 2mm / 3mm then there is a problem. If so check the internal cartridge is inserted correctly.
Note re Black Head / Blue bottom style Housings: When closing the housing up, watch out for the prongs / guides under the black header unit. A loose cartridge might mis-align and be damaged / pierced by them.
When closed turn the water supply back on. (If you have a bypass valve make sure it is turned back on).
Open up your cold water taps for 5 minutes and flush toilets to let any trapped air escape.
The water may look cloudy for a while but will settle down.
