Syem Startup
Syem Maintenance
Time Eimate: 8-12 hours (We recommend running 4 full tanks of water through your new syem. Each
tank should take 2-3 hours, depending on your home’s water pressure levels).
NOTE! Do not drink water from your new syem until you have completed Syem Startup. The
ushing process is needed for your lters to begin working.
NOTE! Do not send water through your fridge until ushing is complete, carbon nes ushed
during artup will clog your refrigerator.
1. Turn the Tank Valve to the Closed position (refer to page 22).
2. Open the water supply to the RO Syem (use Cold Water Supply and Feed Water Adapter Valve refer to
pages 14 and 15) (Make sure the main water supply is also on)
3. Open handle on the RO Faucet (refer to page 17) and wait up to 10 minutes for water to art dripping from
faucet. Let the water drip for 5 minutes.
4. Close the handle on the RO Faucet and wait 10 minutes for pressure to build. Then carefully check your RO
Syem for any leaks (Feel or visually inspect every connection point for leaks. If a leak occurs, turn the Feed
Water Adapter Valve OFF, refer to page 27).
5. Turn the Tank Valve to the Open position.
6. Allow the Water Storage Tank to ll completely (this takes about 2-3 hours depending on your incoming
water pressure).
7. Flush the syem by opening the RO Faucet handle until the ored water is completely emptied and the
ow is reduced to a trickle (about 1-5 minutes).
8. Close the RO Faucet handle and allow the Tank to ll again.
9. Repeat eps 6-8 two more times (about 4-6 hours). (Occasionally check for leaks during this time)
10. Let the tank ll one nal time and sit overnight (8+ hours) before ushing the water
11. After the 5th tank is lled you may drink the water.
12. Check for leaks daily during the 1 week of use and periodically thereafter.
NOTE! You may notice that the water has a milky color during the 1 week. This is an indication of
air bubbles in the water. This is normal during this period and the water is safe to drink.
These recommendations are intended for maximum eciency of your RO Syem.
Filter and RO Membrane Storage
- Store unopened lters in an airtight container to prevent them from absorbing air. This prolongs the
shelf life of the lters and avoids any possible odors or contamination from the air.
- Using this method it is okay to ore lters for several years. Store in a cool, dry, dark place (avoid
heat and moiure contamination).
Extended Syem Non-Use
- If you will not be using the RO Syem for two weeks or more you will need to follow the “Vacation
Mode” guide on page 27.
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
(refer to page 14), the Feed Water Adapter Valve (page 15), and
the Tank Valve (page 22). 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 (refer to page 19). 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 on Page 26.
How to Change the RO Membrane
(Recommended about once a year)
NOTE! Make sure you have shut down the
RO Syem (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. Inall the new RO Membrane in the Housing in the correct direction
you noted earlier. Make sure to push the Membrane in rmly, then close the Housing by tightening the cap with
your hand. If this is the only/la lter you are replacing continue to the Rearting the Syem section on Page 26.
CTO SEDGAC
Make sure the O-Ring is in place before
you tighten the Membrane Housing Cap
How to Change the Inline Po Carbon Filter
(Recommended about once a year)
NOTE! Make sure you have shut down the RO Syem
(Step 2 in the Prelters section).
1. Fir disconnect the Stem Elbow and Stem Tee from the sides of the Inline Po Carbon Filter.
2. Note the orientation of the old lter, inall the new lter in the same orientation. Remove the old lter from
the holding clips and discard. Next, insert the new lter into the holding clips and connect the Stem Elbow
and Stem Tee to the new Inline Po Carbon Filter (check page 12 for layout). If this is the only/la lter you
are replacing continue to the Rearting the Syem section on Page 26.
