INSTALLATION STEPS2
For models that include a dedicated faucet:
NOTE: This system requires an existing faucet hole at least 1/2” in diameter in
the sink or countertop to install the supplied dedicated faucet. You may also
replace an existing kitchen sink sprayer, soap dispenser, or use pre-existing
hole on the sink or countertop.
If using a hole from a current dedicated faucet, ensure the hole is at least 1/2”
in diameter.
If drilling a new hole, ensure faucet body will mount at against surface and there is
sucient tubing between faucet body and system manifold. If drilling, we strongly
recommend using a professional. Please wear safety glasses when drilling.
For model without a dedicated faucet:
NOTE: This system requires an existing faucet hole, please refer to the
installation guide of the faucet purchased to determine hole size needed to drill.
This system requires tubing to be 1/4” outside diameter. If you have 3/8” outer
diameter tubing, you will need to purchase quick connect adapters.

NOTICE
Safeguards
• If you experience a tubing connection leak, shut o cold water, disconnect
and re-set the tube.
• Do not install this system where the line pressure may exceed 80 psi. The
operating pressure range for this system is between 40-80 psi.
• Install on COLD water lines only (40°F-100°F).
• It is recommended that your system be installed inside and out of direct
sunlight. The system must be protected from both direct sunlight and
freezing temperatures.
• System and installation shall comply with applicable state and local laws.
• Do not operate without the lters installed.
• Do not use with water that is microbiologically unsafe or of unknown water
quality without adequate disinfection before or after the system.
• Systems certied for cyst reduction may be used on disinfected waters that
may contain lterable cysts.
• This reverse osmosis system contains a replaceable treatment component
that iscritical for the eective reduction of total dissolved solids. It is
recommended to periodically test this reverse osmosis system to verify it is
performing properly.
• This reverse osmosis system contains a replaceable component critical
to the eciency of the system. Replacement of the reverse osmosis
component should bewith one of identical specications, as dened
by the manufacturer, to ensure the same eciency and contaminant
reduction performance.
• This system has been tested and certied for Nitrate/Nitrite reduction
according to NSF/ANSI Standard 58. Proper maintenance is required to keep
the system functioning according to specications. It is recommended you
check your water every 3-4 months. Nitrate/Nitrite test included, see test kit
for sampling instructions.
CARE & SAFEGUARDS 13
Specications
Eciency rating is the percentage
of the inuent water to the system
that is available to the user as
reverse osmosis treated water.
This measurement is taken under
operation conditions that approximate
typical daily usage. The system’s
eciency rating was veried by testing
in accordance with Section 6.8 found
in NSF/ANSI 58.
Recovery rating is the percentage of
the inuent water to the membrane
portion of the system that is available
to the user as reverse osmosis treated
water when the system is operated
without a water tank or when the
water tank is bypassed.The system’s
recovery rating was veried by testing
in accordance with Section 6.8 found
in NSF/ANSI 58.
Because the performance of a
reverse osmosis membrane is
highly dependent upon pressure,
temperature, and Total Dissolved
Solids (TDS), the following should be
used for comparison only.
Lower temperatures are directly
proportional to slower ow rate. The
reverse osmosis system should not be
installed in a location susceptible to
freezing. Incoming water temperature
should not exceed 100°F (38°C). The
more TDS in the supply water, the
more lter time required. Incoming
TDS should not exceed 1000 ppm.
Higher water pressure enables a
higher ow rate. Pressure must be
at or above 40 psi for proper system
operation. You may consider installing
a booster pump if your pressure is
below 40 psi.
Flow rate and output are determined
by the following factors:
1. Incoming water temperature
2. Total dissolved solids (TDS) present
in supply water
3. Incoming water pressure
4. Tank size and amount of water in
the tank
Do not use the system on microbiologically
unsafe water, or water of unknown
quality without adequate disinfection
before or after the system. This system
is certied for cyst reduction and may
be used on disinfected water that may
contain lterable cysts.
Installations in The Commonwealth of
Massachusetts: The Commonwealth of
Massachusetts requires installation be
performed by a licensed plumber and
does not permit the use of saddle
valves. Plumbing code 248—CMR of the
Commonwealth of Massachusetts must
be followed in these cases.

Arsenic Facts
Arsenic (As) is a naturally occuring
contaminant found in many ground
waters. Arsenic in water has no color,
taste or odor. It is measured by a
laboratory test. Public water utilities
must have their water tested for
arsenic. You can get the results from
your water utility. If you have your own
well, you can have the water tested.
The local health department or the
state environmental health agency
can provide a list of certied labs.
Information about arsenic in water
can be found on the internet at the
U.S. Environmental Protection Agency
website:
epa.gov/safewater/arsenic
There are two forms of arsenic:
pentavalent arsenic (As(V), As(+5), and
arsenate) and trivalent arsenic (also
called As(III), As(+3), and arsenite).
Although both forms of arsenic are
potentially harmful to human health,
trivalent arsenic is considered more
harmful than pentavalent arsenic. In
water, arsenic may be pentavalent,
trivalent, or a combination of both.
Special sampling procedures are
needed for a lab to determine what
type and how much of each type of
arsenic is in the water. Check with the
This system has been tested for the treatment of water containing pentavalent
arsenic (also known as As(V), As(+5), or arsenate) at concentrations of 0.05
mg/L or less. This system reduces pentavalent arsenic, but may not remove
other forms of arsenic. This system is to be used on water supplies containing
a detectable free chlorine residual at the system inlet or on water supplies
that have been demonstrated to contain only 50 ppb (0.050 mg/L) pentavalent
arsenic. Treatment with chloramine (combined chlorine) is not sucient to
ensure complete conversion of trivalent arsenic to pentavalent arsenic. Please
see the Arsenic Facts section below for further information.
labs in your area to see if they can
provide this type of service.
If you get your water from a public
water utility, contact the utility to
nd out if free chlorine or combined
chlorine is used in the water system.
The AQ-SFRO2 system is designed
to reduce pentavalent arsenic only.
It will not convert trivalent arsenic
to pentavalent arsenic. This System
was tested in a lab. Under testing
conditions, the system reduced [0.050
mg/L (ppm)] pentavalent arsenic to
0.010 mg/L (ppm) (the USEPA standard
for drinking water) or less. The removal
performance of pentavalent arsenic
of the system may be limited due to
water quality conditions (i.e. iron-
containing water or other water quality
conditions). Have your treated water
tested for arsenic to check whether the
system is working properly.
The SmartFlow
®
Membrane of the
AQ-SFRO2 system must be replaced
every 12 months to ensure the system
will continue to remove pentavalent
arsenic. Information regarding
component identication and places
to purchase replacement are listed in
the manual.
FILTER REPLACEMENTS 15
Carbon Block and Advanced Carbon Block
Replace every 6 months*
The Carbon and Advanced Carbon Blocks are replaceable activated carbon
cartridges located in Stages 1 and 3. It is recommended to replace these
cartridges at least every 6 months. You may need to replace more often with high
water usage or high sediment levels. Timely replacement of these cartridges will
protect the RO Membrane from high levels of chlorine and/or sediment. As these
lters build up with sediment, you may notice slower water output.
Scan here to view the Carbon Block and
Advanced Carbon Block replacement manual.
SmartFlow
®
Membrane
Replace every 12 months*
The SmartFlow
®
Membrane is located in Stage 2. This membrane reduces the
dissolved solids and organic matter. Most municipally treated water has a 7.0-7.5
pH. In this case you would need to replace your SmartFlow
®
Membrane every 12
months. Membrane life depends on pH and supply water hardness. Higher pH
shortens membrane life by causing pin-hole leaks. When output, water quality,
and production rate decrease, it is time to replace the lter.

Step 1: Ensure water is owing from the faucet. If water is owing, close
faucet and come back in 1-2 hours to re-check pressure. This will allow
enough time for the tank to be lled.
Step 2: Check the feed temperature, pressure, and TDS to ensure inlet
water conditions for proper operation are met.
Step 3: If it has been over six months since changing the Carbon Block
and/or Advanced Carbon Block, we recommend changing these lters. We
advise replacing the Carbon Block rst, then the Advanced Carbon Block if
the issue is not resolved
NOTE: The best ow rate will be 0.7 GPM when the tank is completely
full. The ow rate may slow as the water is depleted from the tank.
Step 4: Check and make sure the
tubing is fully inserted into the
system manifold until tubing can
no longer be pushed. A loose
connection can cause a leak at the
inlet/outlet.
Step 5: Once all tubing is installed
and the system is re-connected, turn
the water valve back on and check
for leaks.
Step 6: Make sure that the
cartridges are in the locked
position. They should be rotated fully clockwise until the handles are
horizontal (see illustration on page 18).
NOTE: If the unit is still leaking after checking the cartridges and tube
connections, shut o the cold water valve to the RO unit and contact
Customer Support at 866-662-6885.
If you are experiencing a leak or drip from the manifold, do not attempt
to dissemble. Turn cold water valve o and contact Customer Support
at 866-662-6885.

TROUBLESHOOTING GUIDE18
How do I know I connected the tubing all the way?
The tubing must be inserted 0.625". We recommended making a mark
at 0.625" from the end of the tube and then inserting the tube all the
way up to that point. Since leaks may not appear immediately after
installing, we recommend re-checking for leaks an hour after the tank
has lled and continuing to check for leaks periodically.
Can I install the cartridges in the wrong stage?
No, the guides to help with insertion can only t in their correct
cartridge slot.
How do I know I connected the lter correctly?
The cartridge handle should be horizontal and handle labeling should
be right side up.
How do I know the system is ltering my drinking water?
The best way to know if you're drinking ltered water is to purchase a
water quality test kit and a contaminant reduction test.
Or, have a licensed professional test your drinking water.
Why is my water grey or black?
Carbon "nes" can be present in your water when new lters are rst
installed and will go away after the ushing cycle. Ensure you ushed your
system for the adequate time on page 11.

Common
Questions
Issue Resolution
Why is my ow rate slow?
The inlet water pressure will aect your ow rate. While this system has
a 0.7 gpm ow rate, if your ow rate is less than that, you can consider
purchasing a booster pump.
Do I need to depressurize my system before replacing the lters?
Yes, you must depressurize the system before replacing any of the
lters. Failure to release pressure can result in permanent system
damage. Do so by closing the inlet tee valve and closing the water
tank valve. Release the pressure by turning on the dedicated faucet
until water stops owing. Once water has stopped owing from
the dedicated faucet, turn the faucet o and proceed with lter
replacement.
I have an existing dedicated faucet. Can I use that with this
system?
Yes, as long as the faucet is compatible with a 1/4” tubing.
I have an existing air gap dedicated faucet. Can I use that with this
system?
Yes, as long as the faucet is compatible with a 1/4” tubing. There is no
need for a separate air gap adapter installed on the drain line.
How do I dispose of the lter cartridges?
You can take the entire lter cartridge and put it in the trash. While
it can’t be recycled, it is designed with minimal components to help
reduce waste.
When handling the lter cartridges, is it suppose to sound like
something is moving around inside of the cartridge?
