Filter Change Inructions
This RO Syem contains Filters that mu be replaced at regular intervals to maintain proper performance.
Use only authentic Express Water lters.
How to Change the Sediment, GAC, and Carbon Block Filters (Prelters)
(Recommended about every 6 months)
1. You will need a clean cloth, dish soap, lter housing wrench
and appropriate Sediment, GAC, and Carbon Block Filters. (We
also recommend a bucket or bin large enough for the syem
to sit in. The syem will release water when it is disassembled.)
2. Turn o the Cold Water Supply connected to the RO Syem,
the Feed Water Adapter Valve, and the Tank Valve. Then open
the RO Faucet handle to release pressure, close handle when
the ow of water ops.
3. Place the RO Syem in the bucket and unscrew the 3 Prelter
Housings using the Filter Housing Wrench. Remove old lters and dispose of them.
4. Wash the Prelter Housings with dish soap then proceed to rinse until all soap is removed.
5. Ensure that your hands are washed clean before unwrapping the new lters. After unwrapping, place the
new lters inside their correct housings. Make sure the O-Rings are in their proper locations.
6. Tighten the Prelter Housings using the Filter Housing Wrench. Do not overtighten. If these are the only
lters you are replacing continue to the Rearting the Syem section.
How to Change the RO Membrane

RO Syem (Step 2 in the above section).
