READ THIS FIRST
Please pay attention to the following in󰍰allation and safety recommendations:
- Read the in󰎤allation manual before in󰎤alling this sy󰎤em.
NOTE! Please make sure your in󰎤allation location has enough room for the RO Countertop Sy󰎤em. We sugge󰎤
an in󰎤allation location where the RO Faucet can overhang your sink.
Incoming Water
Incoming water pressure mu󰍰 be between 45 PSI and 80 PSI. If your water pressure is under 45 PSI you
will need a boo󰍰er pump on your sy󰍰em. If your water pressure is above 80 PSI you will need a pressure
regulator on your sy󰍰em. Te󰍰 your water occasionally to make sure the sy󰍰em is performing. If your water is
microbiologically unsafe or of unknown quality do not use this sy󰍰em without adequate disinfection before
or after the sy󰍰em. Extremely hot or cold incoming water will damage the sy󰍰em and cannot be used.
Leaks
Inspect all connections after the in󰍰allation to make sure no leaks occur, wait until after the sy󰍰em is
pressurized to inspect again. Check sy󰍰em occasionally after in󰍰allation or maintenance to make sure no
leaks have developed.
General
This RO Sy󰍰em unit is for climate controlled indoor use only. Exposure to overly high or low temperature
ranges will damage the unit. Follow all of your 󰍰ate and local laws and codes regarding plumbing even if
they dier from what is 󰍰ated in this manual. If your 󰍰ate law requires use a professional licensed in󰍰aller or
plumber who meets the requirements of this sy󰍰em. All o-rings, ttings, lter cani󰍰ers, and teon tape wears
out after a certain period of time. The lifetime of your components are subject to change with the quality of
the water supplied. Do not handle an unwrapped lter directly with your bare hands as this can cause early
lter failure. Use appropriate eye protection if you are performing any drilling.
Maintenance
The owner/user is obligated to properly maintain the RO Sy󰍰em when necessary, at lea󰍰 once a year.
This includes the following:
- Replace any o-rings used
- Replace any connectors and lter housings with proper replacement parts
- Sanitize your sy󰎤em as often as needed (this changes with the prole of your area’s incoming water)
- Always use proper replacement lter cartridges with the correct size and length replacements
- Replace any teon tape used

Introduction
Fir󰍰, get ready to have safe clean water. You’re going to need under 30 minutes for the initial in󰍰allation
and two hours to run the sy󰍰em and ush out your lters before you can drink the water.
Take a Look at Your Sy󰎣em
Fir󰍰 inspect your sy󰍰em and make sure all parts are present and have not been damaged during shipping.
We’ve taken every 󰍰ep to make this process as easy as possible but if you discover any problems or run in
to que󰍰ions during your in󰍰allation ju󰍰 give us a call:
1-800-992-8876 Monday to Friday 10 am - 5 pm PST
Take a Look at Your Faucet
If you have a 󰍰andard kitchen or bathroom faucet you can get up and running right away, ju󰍰 remove
your aerator and screw the diverter valve on. We support 13/16” male threaded faucets, 13/16” female
threaded faucets, and 15/16” female threaded faucets. If you have another type of faucet you will need to
visit a home or plumbing supply 󰍰ore to adapt from your faucet type to 13/16” male (as the diverter valve
is 13/16” female).
Get Ready for Pure Water
The ow through your faucet makes perfectly pure RO water at a rate of about 3 gallons an hour (this may
be less depending on your home’s water pressure) so we’ve found the ideal setup is lling a large pitcher
or dispenser with water.

Tubing Quick Connect Guide
To Cut Tubing
Make your cuts again󰍰 a at cutting surface with a razor blade, or use a handheld tube cutter. Any cuts to
your Tubing mu󰍰 be perfectly 󰍰raight.
NOTE!
Improperly cut Tubing may leak water or fail to lock into Fittings.
Wait until all elements of your RO Sy󰍰em are in their nal locations before cutting your Tubing.
Make sure you measure the length you will need before cutting.
Attach Tubing
Push Tubing in 󰍰raight and level with the
Collet. The Tubing will go 5/8ths of an inch
into the Collet before the lock is activated.
Pull out on the Tube to make sure the lock
has activated and the Tubing is secure.
NOTE! Once connected, make sure to
check tubing is secure.

In󰎣allation
1. Identify if your faucet is compatible with the 13/16”
female threaded diverter valve
- If it is not compatible you may need the 13/16”
male to 13/16” male adapter -or the- 15/16” male to 13/16”
male adapter
- If your faucet is not compatible with either of these
adapters you will need to purchase an appropriate adapter
to connect your faucet to the diverter valve
1. Push the RO Faucet stem into the Faucet Adapter on the
Post Activated Carbon Filter
2. Make sure the faucet is fully pushed in
CAUTION!
The water supply to the unit MUST be COLD WATER ONLY. Using HOT WATER will severely damage
your RO System.

Using the Sy󰎣em
Sy󰎣em Maintenance
Sy󰎣em Startup
When the diverter valve is in the vertical position
water will come through your sink’s faucet into your
sink. You can still use faucet as you normally would.
When the diverter valve is in the horizontal position
water will be sent to the RO System and pure clean
drinking water will come through your RO faucet.
Turn the Diverter Valve to the horizontal position to direct ow
to your RO System.
Turn on the cold water from your feed faucet.
When using the RO Faucet the waste water (carrying rejected contaminants away from the RO membrane)
will pour from the smaller port into your sink. Never drink this waste water, although it can be use for
some household uses like water plants.
This RO System contains Filters that must be replaced at regular intervals to maintain proper performance.
Use only authentic Express Water lters.
How to Change the SED (Sediment), GAC
(Granular Activated Carbon), and PAC (Post
Activated Carbon) Filters
(Recommended about every 6 months)
1. You will need Express Water inline Sediment,
Granular Activated Carbon, and Post Activated Carbon
Filters. We also recommend a bucket or bin large
enough for the system to sit in. The system will release
water when it is disassembled.
2. Make sure that water ow to the system is o
3. Place the RO System in the bucket or a sink and disconnect the the elbows from each side of the SED, GAC,
and PAC lters. For detailed directions of disconnecting these refer to the Quick Connect Guide (Page 12)
One side of the SED has an inow tube instead of an elbow
One side of the PAC has the faucet adapter which must be unscrewed
4. Note the correct orientation and ow direction of these lters then remove the lters and discard them.
5. Set the new lters in place in the same orientation
6. Reconnect the stem elbows, tube, and faucet adapter to the new SED, GAC, and PAC lters
7. If these are the only lter you are changing begin the “System Startup” instructions on Page 14.
Once you are sure there are no leaks and water has begun to
come out of the RO Faucet, let the system run for two hours.
This will ush out any loose carbon nes and prime your lters.
Inspect your system occasionally during this time to make sure
there are no leaks.
Your water may be cloudy for the rst week of operation.
This is just air bubbles escaping from the new system. You can
shift the sides of your system up and down while running your
water to help this air escape.
Now your system is ready for use and the water from the RO
Faucet is ready to drink.

How to Change the RO Membrane
(Recommended about once a year)
NOTE! Make sure water ow to the system is o
1. Remove the 3 stem elbows attached to the Reverse
Osmosis Membrane Housing. For detailed directions of
disconnecting these refer to the Quick Connect Guide
(Page 12)
2. Unscrew the cap from the Membrane Housing and remove the Membrane inside, be sure to note the
correct orientation of the membrane
3. Wash out the RO Membrane Housing
Mix ½ gallon of water with 1 tbsp of household bleach
Note: Do not add bleach directly to the membrane housing
Scrub the inside of the membrane housing with the bleach mixture
Rinse the housing until all traces of bleach are gone as bleach will damage your membrane
4. Install the new RO Membrane in the Housing in the correct direction you noted earlier (the single large
rubber ring will face towards the cap). Make sure to push the Membrane in rmly and check to see if the
o-ring is in place. Then close the Housing by tightening the cap with your hand.
5. Now reattach the stem elbows to the RO Membrane Housing. If this is the only/last lter you are changing
begin the “System Startup” instructions on Page 14.
Make sure the O-Ring is in place
before you tighten the Membrane
Housing Cap
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 store lters for several years. Store in a cool, dry, dark place (avoid heat and
moisture contamination).

FAQ’s
Does this sy󰎣em lter Fluoride, Lead, Pharmaceuticals, and Arsenic?
Yes, as well as Cyanide, Phosphate, Pe󰍰icides, Sodium, Cadmium, Sulfates, and many other contaminants
up to certain levels. You may need other changes to media for high levels of these sub󰍰ances.
What PSI do I need? What is the operating pressure?
The minimum PSI for the sy󰍰em is 45 and the maximum PSI is 80. If your PSI is too high you can purchase
a Pressure Regulator to reduce your pressure to acceptable levels. Let us walk you through these options;
call us at 1-800-992-8876 Monday - Friday 10am - 5pm PST or visit expresswater.com
Does this unit soften water?
Your RO Sy󰍰em will soften water. However, hard water does reduce the lifespan of your lters.
What is the discharge rate?
The typical discharge range is one to three gallons for every one gallon produced. Your water pressure,
incoming water quality, and water temperature will aect your RO Sy󰍰em’s discharge rate.
How often do I change Filters? Is there an indicator?
The Sediment, GAC, and PAC Filters should be changed every 6 months. The RO Membrane should be
changed every one year at the same time as the second change of the 6 month lters. There is no direct
indicator for lter changes. However, if you notice a drop in water quality before the 6 months or 1 year
mark this may mean that due to your water quality your lter has degraded. If you reach 6 months or 1
year without noticing a change in ta󰍰e you should 󰍰ill change your lter at this point as they are no longer
viable.
Can I add additional lters to my current sy󰎣em?
Yes, each sy󰍰em is fully upgradeable. Check the Upgrades and Accessories section at ExpressWater.com
for more information.
Can I reuse discharge water?
Never consume discharge water. With proper in󰍰allation it is possible to utilize your discharge water.
Contact Express Water to speak with a qualied representative who can give you more information based
on your situation.
How long does the sy󰎣em la󰎣?
With proper maintenance and average water quality an RO Sy󰍰em should la󰍰 5-10 years.
Does this produce aquarium safe water?
While the water is perfectly safe for human consumption, we sugge󰍰 in󰍰alling our Deionization Filter
Upgrade to create water for aquatic life.
Why do I need to ush the sy󰎣em?
New lters (or lters that have experienced extended disuse) can develop carbon residue. Two hours of
con󰍰ant ow is recommended to release any extra carbon before the water is safe to drink.
