Product Codes: FIL/SC-REF16 | FIL/SC-REF32

Thank you for your purchase and for choosing the greener option for replacing your media.

How to Replace Your Media/Powder

Turn off the water supply.

1. Take a bucket and place it under the filter housing to catch any water spillage.

2. Then press the red or black button (pressure release valve) on top of the housing unit (if you have one) to release pressure. Otherwise open up the cold water kitchen tap.

⚠️ Note: When you press the pressure release valve on top of the canister, a lot of water can come out - be prepared with a cloth.

⚠️ Note: Do not assume all pressure has been released just because the water has stopped coming out of the release valve. Keep pressing it while trying to remove the canister - suction can keep it held on tightly even after the flow stops.

3. Remove the bottom housing from the head (Lefty loosey / righty tighty!)

⚠️ Note: Even with the water supply off, it is not an easy job to get all the old media out of the container. Keep a good bucket of water handy for cleaning out the container - you'll need plenty of water and time.

4. Remove the cartridge and open it. Green-topped "SC" coded Scale Centurion cartridges are a quarter-turn twist/pull off.

White "FIL" coded cartridges are either as above or have a jam jar type lid at the bottom which unscrews.

5. Discard the old media. (The water filter black media can go on flower beds etc. - but not on compost. The old Scale Centurion should be put in the bin - it cannot be recycled.)

6. Rinse out the cartridge casing with cold soapy water and wash the rubber washer on top of the cartridge casing in warm soapy water to remove any residue. Then rinse.

7. Carefully pour the new media into the cartridge casings.

⚠️ Note: Be careful when opening the cellophane bags containing the new media. They can split when removing the sealing tape, causing the media to spill out of the bottom - open them carefully while holding the sachet over the cartridge or a tray.

CAUTION: With the water filter / white cartridge you will get a very fine carbon dust in the air. This will be minimal but if you're very asthmatic you may choose to do the pouring outside.

Media / Powder Quantities

To make one FIL16, use TWO bags of FIL-REF
To make one SC16, use ONE bag of SC-REF
To make one FIL32, use FOUR bags of FIL-REF
To make one SC32, use TWO bags of SC-REF

Do Not Overfill

Both types of media/powder have been carefully measured.

White FIL cartridges / black powder: There should be a gap of at least 3 inches between the black powder and the top of the cartridge. This is because the powder slowly expands when wet.
Scale Centurion / white powder: The cartridge should be less than a third full. This expands in the water.

Re-Insert Cartridges

When done, close and put back the cartridges into the housing unit.

Position top and bottom correctly, i.e. carefully guide the top of the cartridge up into the centring slot, making sure you guide it carefully past any centralising prongs.

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 O-rings 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 gap, there is a problem - 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.

Such an improvement over unfiltered water. Losing microplastics, scale, chlorine and all the other nasties that can work their way in is just a bit of piece of mind for me in relation to my kids.

– Nick Love

I've had the filter installed for 1 month now and the water tastes loads better and no more smell of chemicals, just clean fresh filtered water I'd say it's the best water I've ever had.

– Neil Bradfield

“My filter fits easy and I am happy. We weigh the old filter when it is removed, filled with gunge which never got into our bodies with this filter. It’s quite frightening. My filter is worth every penny!

– Kathleen Gibson
