Filter Change Instructions
This Commercial RO System contains Filters that must be replaced at regular intervals to maintain proper
performance. Use only authentic Express Water filters.
How to Change the SED and 2 ACB’s (Prefilters)
(Recommended about every 6 months, depending on water use)
1. You will need a clean cloth, dish soap, and appropriate Sediment and
Carbon Block Filters. (We also recommend a bin large enough for the
system to sit in. The system will release water when it is disassembled.)
2. Turn off the Cold Water Supply connected to the RO System (refer to
page 6), the Feed Water Adapter Valve (page 7), and the Tank Valve [if you
are using a tank]. Then open your pure water outflow to release pressure,
close outflow when the flow of water stops on its own.
3. Place the RO System in the bin and unscrew the 3 Prefilter Housings using the Filter Housing Wrench.
Remove old filters and dispose of them.
4. Wash the Prefilter 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 filters. After unwrapping, place
the new filters inside their correct housings (refer to page 9). Make sure each Housing has an O-Ring firm-
ly in place in the Housing’s lower groove (just below the threading).
6. Tighten the Prefilter Housings using the Filter Housing Wrench. Do not overtighten. If these are the only
filters you are replacing continue to the Restarting the System section on Page 14.
How to Change the RO Membrane
(Recommended about every 6 months to 1 year.
Lifespan varies based on quality of incoming water.)
NOTE! Make sure you have shut down the
RO System (Step 2 in the above section).
1. Open the RO Membrane Housing by unscrewing the cap. Pull out the RO Membrane with a pair of
pliers. Be sure to note which side is the front and which side is the back.
2. Wash out the RO Membrane Housing. Install the new RO Membrane in the Housing in the correct
direction you noted earlier. Make sure to push the Membrane in firmly, then close the Housing by
tightening the cap with your hand. If this is the only/last filter you are replacing continue to the Restarting
the System section on Page 14.
SED
Make sure the O-Ring is in place before
you tighten the Membrane Housing Cap
How to Change the Inline Post Activated Carbon Filter
(Recommended about once a year)
NOTE! Make sure you have shut down the RO System
(Step 2 in the Prefilters section).
1. First disconnect the Male Elbow and Male Tee from the sides of the Post Activated Carbon Filter.
2. Remove the old teflon tape from the Male Elbow and Male Tee and apply 6-8 rounds of new teflon tape,
then screw these fittings into your new Post Activated Carbon Filter
3. Note the orientation of the old filter and it’s connection points, install the new filter in the same orientation.
Remove the old filter from the holding clips and discard. Next, insert the correct tubing into the same
points as the old filter (refer to the System Diagram on Page 3). If this is the only/last filter you are replacing,
continue to the Restarting the System section on 14.
