INSTALL COLD WATER SUPPLY FITTING
(Included)
This fitting will be installed on the cold water pipe. The fitting
must provide a leak-tight connection to the Reverse Osmosis
1/4" tubing. Locate the cold water line in the sink cabinet. It
is recommended, but not required, that the cold water line be
soft water.
Complete the following steps to install the water supply fitting.
1. Close the water shutoff valve (angle stop valve) that the
water supply fitting will be installed on, and open faucet(s)
to relieve pressure.
2. Disconnect the existing cold water line from the water
shutoff valve.
3. Make sure that the water supply fitting’s gasket is inside
the female threaded portion of the fitting.
4. Install the water supply fitting onto the cold water shutoff
valve, where the existing cold water line was removed,
and hand tighten. Be careful not to cross thread or overtighten.
5. Connect the existing cold water line to the male threaded
portion of the water supply fitting and hand tighten. Be
careful not to cross thread or overtighten.
OPTIONAL PIPE FITTINGS
(compression type shown)
NOTE: Be sure to turn off the water supply and open a
faucet to drain the pipe.
Complying with plumbing codes, install a fitting on the cold
water pipe to adapt 1/4" OD tubing. A typical connection is
shown in Figure 6B. If threaded fittings are used, be sure to
use pipe joint compound or thread sealing tape on outside
threads.

Step B - Install RO Drain Under Sink
INTRODUCTION
A suitable drain point is needed for the drain water from
the Reverse Osmosis filter. You have two options:
• Install the Drain Adaptor included with your unit
As shown in Figures 7-9, the drain adaptor is
installed onto your sink’s drain pipe above the P-trap.
This is normally used for under sink installations.
• Use another existing drain in your home
As shown in Figures 10 and 11, the drain tube from
the RO filter runs directly to an open drain. This is
often used for remote location installations.
NOTE: An incorrectly connected drain point can
cause water to leak from the faucet’s air gap.
NOTE: Local code may restrict the type of drain
installation to use. Either drain installation type, if
permitted by code, may be used in under sink or
remote location installations. Consult a plumber if
you are not familiar with plumbing procedures.
INSTALL DRAIN ADAPTOR
(Under sink Installation)
The drain adaptor included with your RO system is
designed to fit around a standard 1-1/2” O.D. drain
pipe. In the following procedure, you will install the
drain adaptor above (upstream of) the P-trap. See Fig.
7 & 9. Be sure to comply with local plumbing codes.
NOTE: Before starting this procedure, inspect the
drain pipe under the sink for corrosion, and replace
if necessary, before continuing with installation.
1. Test fit the two halves of the drain adaptor onto the
sink drain pipe, about 6 inches above the P-trap
(See Fig. 8). Make sure that the Q.C. fitting is
toward the direction of the RO faucet (See Fig. 9).
NOTE: Locate so that the drain tubing from the
Reverse Osmosis faucet will run straight to the
adaptor, with no dips, loops, or kinks.
2. Using the hole through the drain fitting as a guide,
mark the pipe where a 3/8” hole will be drilled (See
Fig. 8), and remove the drain adaptor from the pipe.
NOTE: Do not drill through the drain adaptor’s
Q.C. fitting, as this could damage the o-ring.
3. Drill a 3/8” dia. hole in the pipe and remove flash.
4. Clean the sink tailpiece to assure a leak-tight fit.
5. Place the halves of the drain fitting back onto the
sink drain pipe. Use a pencil or similar pointed
object to align the Q.C. fitting so that it is centered
on the hole you drilled.
6. Assemble the nuts and screws, as shown in Figure
8, and tighten both sides equally to secure the drain
adaptor halves onto the pipe. Do not overtighten.
7. Do not connect black tubing to the Q.C. fitting at this
time. It is done after the RO faucet is installed.

Step B - Install RO Drain In Remote Location
INSTALL A REMOTE DRAIN POINT
AND AIR GAP (Remote Location)
Route the drain tubing to an existing drain in the house.
A floor drain, laundry tub, standpipe, sump, etc. are
suitable drain points. See Fig. 11. This type of drain is
the preferred over the p-trap drain adapter.
Always be sure to provide a 1-1/2” air gap between the
end of the hose and the drain point. This will prevent
water from backing up into the system.
NOTE: Check your local plumbing codes.
Telephone cable extension must consist of a male
connector on one end and a female connector on
the other to keep proper polarity. Polarity may be
reversed if a coupler is used and monitor will not
work.
To install a remote drain point, complete the
following steps:
1. Locate the 1/4” red tubing on the Reverse Osmosis
filter assembly. See Fig. 10.
2. Determine if this length is long enough to reach the
drain point. Longer lengths of tubing (see parts list in
back of manual) may be needed.
3. If longer tubing is required, disconnect the 1/4” red
tubing and replace with an adequate length of tubing
to reach the drain point. Refer to Step F later in the
manual on how to disconnect and connect tubing.
NOTE: A flow control insert is located inside the
elbow fitting that the drain tube connects to.
Refer to Fig. 29. Leave this fitting in place.
4. Route the tubing to the drain point and secure at the
end with a bracket (not included). See Fig. 11.
Provide a 1-1/2” air gap between the end of the tube
and the drain. See Fig. 11.

Step C - Install RO Filter Assembly
The fitting on the supply tank may need to be tightened 7-8 full turns to get a good seal.
Do not overtighten.
INSTALL STORAGE TANK
1. Apply thread sealing tape (2 wraps clockwise) to
the threads on the nipple at the top of the tank. See
Fig 13.
2. Locate the tubing connector (shutoff valve). See Fig.
13. Tighten the tubing connector onto the tank nipple 7-8 full turns, being careful not to cross thread or
overtighten.
3. Do not connect the tube at this time. This will occur
later in the assembly.
4. Place the storage tank next to the Reverse Osmosis
Assembly. The tank can be placed upright or on its
side.
INSTALL REVERSE OSMOSIS FILTER
ASSEMBLY
The Reverse Osmosis Filter Assembly is mounted on
hanger washers.
See Fig 12. The hanger washers allow you to lift the
filter assembly from the washers without any hardware
removal. When planning your installation, you need to
leave room for changing filters.
Complete the following steps to install your Reverse
Osmosis Filter Assembly:
1. Remove the cover.
2. Locate mounting slots on back inside of the assem-
bly. See Fig 12.
3. Hold the assembly up to the wall surface and mark
locations for the hanger washers. See Fig 12. Mount
the unit high enough to allow room to change filters
without taking the unit off of the wall.
4. Fasten the hanger washers to the wall using the
screws provided.
5. Hang assembly on washers.
6. Replace cover.

Step E - Install RO Faucet
You will need to select the location of the Reverse
Osmosis Faucet. You have three options to choose
from:
• Use the existing sink top hole for the spray hose
or soap dispenser (Must be 1-1/4” in diameter)
• Drill a new hole in the sink
• Drill a new hole in the countertop next to the
sink
1. Determine where you are going to install your
Reverse Osmosis Faucet.
2. Check to ensure the Reverse Osmosis faucet will
mount flat against the mounting surface.
3. Visually review the routing of the tubes from the
Reverse Osmosis filter assembly to the faucet.
Check to ensure there is adequate tube routing
space between the faucet and filter assembly.
4. If drilling is needed, drill a 1-1/4" diameter hole in
the mounting surface.
IMPORTANT: Drilling holes into countertops and
sinks should only be performed by an installer
who is qualified for drilling such materials.
Drilling of surfaces made of stone or solid surface materials such as granite, marble, Corian™
or other plastic resin products or sinks made of
porcelain or stainless steel may cause permanent, irreparable damage to the sink or countertop surface.

Step F - Connect Tubes
HOW TO CUT AND CONNECT THE TUBES
Your Reverse Osmosis system includes push-in fittings
for quick tubing connection. Review the following
instructions before connecting the tubes in the next
step. Failure to follow these instructions may lead to
future leaks.
Cut tubes to length
1. Use a sharp cutter or knife to cut the end of tubing.
Always cut the tubing square. See Fig. 17.
2. Inspect the tube up to 1” from the end to be sure
there are no nicks, scratches or other rough spots. If
needed, cut the tubing again. See Fig. 17.
NOTE: Tubing lengths should allow for the
removal of the assembly from the hanger washers for servicing. If tubing lengths are shortened
for neater appearance, it may be necessary to
keep the assembly on the hanger washers for
service.
Connect tubes
NOTE: Remove foam plugs before connecting
tubes (See Fig. 16). Discard foam plugs.
1. Push tubing through collet, until it engages the oring. See Fig. 18. Continue pushing until the tube
bottoms out against the back of the fitting. See Fig.
19. Do not stop pushing when the tube engages the
o-ring. Failure to follow these instructions may lead
to future leaks. When a 1/4” tube is fully engaged,
11/16” of the tube has entered the fitting. When a
3/8” tube is fully engaged, 3/4” of the tube has
entered the fitting. Mark tube with a piece of tape or
marker. See Figs. 18 & 19.
2. If additional tubing is required, see parts list at the
end of this manual.
To Disconnect Tubes
1. Push the collet inward with a finger tip. See Fig.21.

Step G - Sanitize, Test and Purge System
SANITIZE THE SYSTEM
Sanitizing is recommended immediately after installation of the Reverse Osmosis system. It’s also recommended after servicing inner parts. It is important that
the person installing or servicing the system have
clean hands while handling inner parts of the system.
Complete the following steps to sanitize the system.
See Fig. 23.
1. Make sure that the water supply to the Reverse
Osmosis system is off.
2. Open the Reverse Osmosis faucet. If the tank is not
already empty, allow the water to empty.
3. Locate an eyedropper and common household
bleach (5.25%).
4. Add 3 ml. of bleach into open end of yellow tubing.
Handle bleach according to bleach manufacturer’s
recommendations. See Fig. 23.
5. Connect yellow tubing to tank connector. See Figs.
13 and 23.
6. Sanitizing the system will be completed during the
pressure test and purging steps on the following
page.
NOTE: The bleach must be removed from the system before drinking the water. See purging instructions on the next page.

PRESSURE TEST THE SYSTEM
NOTE: Complete the sanitizing procedures on the
preceding page before pressure testing.
To pressure test the system, complete the following
steps.
1. Open the water supply valve to the Reverse
Osmosis system.
2. Purge air from the house plumbing by opening several house faucets. Close faucets when water runs
smooth, with no spurting.
3. Pressure will start to build in the RO system. In
about 2 hours check all fittings and connections.
Check for water leaks. Fix leaks if any are found. If
problems exist, refer to the troubleshooting chart or
call the toll free number below).
NOTE: When the system is first pressurized, water
may ''spurt'' from the faucet air gap hole until air is
expelled from the RO system.
Please review the following operating features
before using your Reverse Osmosis system:
NOTE: As with all other water system applications,
leaks may occur. Because the system pressure
builds slowly, leaks may not be immediately apparent. Recheck for leaks 24 hours after purging the
system is complete.
NOTE: Codes in the state of Massachusetts require
installation by a licensed plumber and do not permit the use of saddle valves.
If you live in the state of Massachusetts, review
plumbing code 248-CMR of the Commonwealth of
Massachusetts before proceeding with the installation.
PURGING THE SYSTEM
To purge the system, complete the following steps.
1. Open the Reverse Osmosis Faucet and let water
flow through the system for a 24 hour period. Water
flow will be a slow trickle at this time.
NOTE: Do not consume water from the RO system until purging is complete.
2. Close the Reverse Osmosis faucet after the 24 hour
purging period is complete.
3. In addition, fill and empty the tank twice.
4. When the purging is finished, your Reverse
Osmosis system is ready for use.
You will not have filtered water immediately. It may
take several hours to fill the storage tank and create
maximum flow from the Reverse Osmosis faucet.
Water will run to the drain while the Reverse
Osmosis system is producing water, even if you are
not drawing water from the Reverse Osmosis faucet.
You may hear a small quantity of water going to the
drain at times when water is not being used. This is
normal. Water going to the drain will automatically
shut off when the storage tank is full.
Water Pressure from the Reverse Osmosis faucet will
be less than your standard faucet.

HOW YOUR REVERSE OSMOSIS SYSTEM
WORKS
Introduction: Your Reverse Osmosis (RO) Drinking
Water System uses your household water pressure to
force water through three filters. Minerals and impurities are filtered out. Delicious tasting drinking water
goes to the storage tank-ready for your use. Minerals
and impurities are sent down the drain. The following
paragraphs will explain in detail how your Reverse
Osmosis Drinking Water System works.
Prefilter: Water from the cold supply pipe enters the
prefilter. See Fig. 25. The prefilter is a replaceable
sediment cartridge with activated carbon in its composition. The cartridge reduces taste, odor, sand, silt, dirt,
other sediments, and up to the amount of chlorine
shown in the specifications.
Reverse Osmosis Cartridge: Filtered water flows
from the prefilter to the Reverse Osmosis membrane
cartridge. See Fig. 25. The Reverse Osmosis cartridge
is a tightly wound special membrane. The membrane
reduces the dissolved solids and organic matter. High
quality product water (about one ounce per minute)
exits the Reverse Osmosis cartridge. The product
water flows to the storage tank, postfilter or Reverse
Osmosis faucet. Drain water, with the dissolved solids
and organic matter, is routed to the drain.
Storage Tank: The storage tank holds product water.
See Fig. 25. A diaphragm inside the tank holds water
pressurized to about half of supply water pressure
when the tank is full. This provides fast flow to the
Reverse Osmosis faucet. When the tank is empty of
water, the pressure at the air valve is 5 - 7 psi.
Postfilter: Water goes through the postfilter before
going to the Reverse Osmosis faucet. See Fig. 25.
The postfilter is an activated carbon type filter. Any
remaining tastes and odors are reduced from the product water. Clean, high quality drinking water is available at the faucet.
Reverse Osmosis Faucet: The sink or countertop
faucet has a hand operated knob to dispense drinking
water. See Fig. 25. An air-gap is built into the faucet
drain water connection to comply with plumbing codes.
Shutoff Assembly: The unit has an automatic shutoff
system to conserve water. When the storage tank has
filled to capacity, and the drinking water faucet is
closed, pressure closes the shutoff to stop flow to the
drain. After enough drinking water is used, pressure in
the system drops, and the shutoff opens to allow the
tank to be refilled. See Fig. 25.
Check Valve: A check valve is located in the Reverse
Osmosis manifold above the center cartridge. The
check valve prevents a backward flow of product water
from the storage tank to drain. A backward flow could
damage the Reverse Osmosis Membrane.
See Fig. 25.
Flow Control: Water flow to the drain is restricted by
the flow control. It maintains the desired flow rate to
obtain the highest quality drinking water. The flow control is located inside the elbow fitting on the Reverse
Osmosis manifold drain port. See Fig. 25.

Water Flow Description
1. Water enters prefilter. Sand, silt and other sediments are reduced. Chlorine is also reduced. See Fig. 25.
2. Water leaves prefilter and proceeds to the Reverse Osmosis Cartridge.
3. Water enters the Reverse Osmosis membrane. Dissolved solids are reduced.
4. Processed water leaves the Reverse Osmosis Membrane and flows to the storage tank.
5. Drain water with dissolved solids leaves the Reverse Osmosis membrane and flows to the drain.
6. Faucet is activated.
7. Processed water leaves the storage tank and flows to the postfilter, where it is filtered to ensure fresh taste.
8. Water flows to the Reverse Osmosis faucet.

Maintenance
PREFILTER / POSTFILTER MAINTENANCE
NOTE: It is recommended to replace the prefilter
and postfilter cartridges every 6 months of product
water use or every 230 gallons, whichever comes
first. Replace more often if they begin to plug with
sediment.
The prefilter and postfilter are replaceable sediment
cartridges with activated carbon in their composition.
See Fig. 26. You must periodically replace the prefilter
and postfilter cartridge. This will protect the RO membrane from being destroyed by chlorine. It will also prevent the filters from plugging with sediment.
You may notice a slower output of product water as
the prefilter and postfilter build up with sediment.
Replace the prefilter and postfilter cartridges when this
occurs.
RO MEMBRANE CARTRIDGE MAINTENANCE
The Reverse Osmosis cartridge is a tightly wound special membrane. See Fig. 26. The membrane reduces
the dissolved solids and organic matter. The life of the
Reverse Osmosis membrane cartridge depends mostly
on the pH and hardness of the supply water (see
Specifications). Cartridge life is shorter with higher pH.
For example, if supply water pH is from 6.8 to 7.7, the
cartridge may last for well over one year. However,
cartridge life may be as short as 6 months if the pH is
as high as 8.5 to 10. Higher pH weakens the cartridge
membrane and causes pin-hole leaks. It's time to
replace the Reverse Osmosis cartridge when the production rate and/or quality of product water drops.
Product water may begin to taste different, indicating
solids and organics are passing through the Reverse
Osmosis membrane. See Reverse Osmosis cartridge
replacement.
REVERSE OSMOSIS CARTRIDGE REPLACEMENT
Complete the following steps to replace the cartridges.
NOTE: Do not remove manifold from mounts.
Flexing or twisting may damage the manifold.
1. Remove (turn to the left) the prefilter cartridge from
the manifold to stop flow to the Reverse Osmosis
cartridge.
2. Remove the Reverse Osmosis cartridge.
3. Remove the postfilter cartridge.
4. Discard the cartridges in a proper manner.
5. Install new cartridges in reverse order (post filter,
Reverse Osmosis and then prefilter). Turn cartridges
to the right to reattach to the filter heads. Do not
overtighten.
6. Purge the Reverse Osmosis system. See page 17
for instructions.

Maintenance
FLOW CONTROL
The flow control is required for proper operation of the
Reverse Osmosis system. See Fig. 27. The flow control,
located inside the push-in elbow fitting on the drain port of
the system housing, keeps water flowing through the membrane at the required rate. This ensures that the system produces the best quality product water.
Periodically check the flow control to be sure the small hole
through it is clean and unrestricted.
If the flow control requires service, review the exploded view
in Fig. 27. Assemble and disassemble as shown. If the flow
control remains in the manifold when the push-in elbow fitting is removed, you will need to remove the drain port’s collet and o-ring, as shown in the next section, to retrieve it.
CHANGE COLLET AND O-RING
1. Remove the collet and o-ring from the fitting with a small
screwdriver. Do not scratch the internal walls of the collet
port. See Figs. 28 & 29.
2. Clean collet port, lubricate with silicone-based lubricant,
and insert the o-ring seal into the bottom of the port. See
Figs. 28 & 29.
3. Push the collet inward until it locks in place. See Figs. 28
& 29.

Troubleshooting
Problem: Chlorine taste and/or odor in the RO product water.
Cause: The level of chlorine in your water supply
exceeds maximum limits, and has
destroyed the Reverse Osmosis membrane.
Correction: If the water supply contains more than 2.0 ppm of chlorine, addition-
al filtering of the water supply to the Reverse Osmosis is needed.
Contact your local water supplier. Correct this condition before doing
maintenance on the Reverse Osmosis system.
Cause: The prefilter is no longer removing chlo-
rine from the water supply.
Correction: Replace the prefilter, postfilter and Reverse Osmosis membrane
cartridges. See Page 20.
Problem: Other taste and/or odor.
Cause:
Cause:
Postfilter expended.
Reverse Osmosis membrane cartridge
expended.
Correction: Replace the postfilter cartridge. If taste and odor persist, replace the
prefilter cartridge and Reverse Osmosis membrane cartridge. See
Page 20.
Cause: Contamination in product water storage tank. Correction: Use sanitizing procedures. Replace prefilter and postfilter cartridges.
See page 16.
Cause: System contamination. Correction: Sanitize entire system. Call 1-800-972-0135 for instructions.
Problem: System makes product water too slowly.
Cause: Water supply to the Reverse Osmosis sys-
tem not within specifications.
Correction: Increase water pressure, precondition the water, etc., as needed to
conform before doing maintenance on the Reverse Osmosis system.
Cause: Prefilter or Reverse Osmosis membrane
cartridges plugged with sediment.
Correction: Replace the prefilter cartridge. If rate does not increase, replace the
postfilter cartridge and Reverse Osmosis membrane cartridge. See
Page 20.
Problem: System makes lower amount of product water than usual.
Cause: Storage tank air-charge less than 5-7 psi. Correction: Open Reverse Osmosis faucet and drain tank until flow slows to a
drip. Keep faucet open and check tank pressure. If low, pressurize
to 6 psi. Close faucet to refill the tank.
Problem: High total dissolved solids (TDS) in product water
Cause: Water supply to the Reverse Osmosis sys-
tem not within specifications.
Correction: Increase water pressure, precondition the water, etc., as needed to
conform before doing maintenance on the Reverse Osmosis system.
Correction: Send treated and untreated water samples to a water analysis lab
for testing. It is important to test both the treated and untreated
water to determine system performance. If the TDS is not within the
system’s performance guidelines, replace the prefilter, post filter and
RO membrane cartridges.
Cause: Plugged drain flow control insert. Correction: Replace drain flow control insert. See page 21.
Problem: Continual water flow to drain and low or no water production.
Cause: Missing flow control insert in drain port. Correction: Make sure flow control insert is in place. See page 21.
Problem: Water leaking from faucet airgap hole.
Cause: Drain side of faucet airgap (3/8” black tub-
ing) plugged, restricted or incorrectly connected to drain point.
Correction: Inspect and eliminate restriction or plug. Check that drain line is
routed properly. Refer to installation instructions for proper drain
connection. See pages 6 & 10.
Problem: Water leaks at push connect fittings
Cause: Tubing not cut square. Correction: Cut tubing square. See pages 14 & 15.
Cause: Tubing not pushed in all the way. Correction: Push tubing in all the way. See pages 14 & 15.
Cause: Tubing nicked. Correction: Remove tube from connection. Remove nicked portion by cutting
tube to shorter length. Reinsert in connection. See pages 14 & 15.
If removing the drain line, leave in place the fitting that it connects
to. See page 21.
Cause: Outer tubing surface finish not smooth. Correction: Remove tube from connection. Remove problem area by cutting
tube to shorter length. Reinsert in connection. See pages 14 & 15.

This system has been tested according to NSF/ANSI standards for the reduction of substances listed above. The concentration of the indicated substances in water entering the system was reduced to a concentration less than or equal to
the permissible limit for water leaving the system, as specified in NSF/ANSI Standards 42, 53, 58, 401 and P231.
Testing was performed under standard laboratory conditions. Actual performance may vary.
Efficiency rating means the percentage of the influent water to the system that is available to the user as reverse osmo-
sis treated water under operating conditions that approximate typical daily usage.
Recovery rating means the percentage of the influent 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 storage tank or when the storage tank
is bypassed.
Do not use with water that is microbiologically unsafe or of unknown quality, without adequate disinfection before or after the
system. This system is certified for cyst reduction, and may be used on disinfected water that may contain filterable cysts.
This system is acceptable for treatment of influent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite in
combination, measured as N, and is certified for nitrate/nitrite reduction only for water supplies with a pressure of 40 psig
(276 kPa) or greater.
*Tested and verified by IAPMO R&T.

ARSENIC FACTS
Background
Arsenic (abbreviated As) can occur naturally in well water. There are two forms of arsenic: pentavalent arsenic
[also called As
(V), As (+5), and arsenate] and trivalent arsenic [also called As (III), As (+3), and arsenite].
Although both forms are potentially harmful to human health, trivalent arsenic is considered more harmful than
pentavalent arsenic. In well water, arsenic may be pentavalent, trivalent, or a combination of both. Additional
information about arsenic in water can be found on the Internet at the U.S. Environmental Protection Agency
(USEPA) website:www.epa.gov/safewater/arsenic.html.
Testing Your Water
Arsenic in water has no color, taste or odor. It must be measured by a lab 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
certified labs. The cost is typically $15 to $30.
Pentavalent vs.Trivalent Arsenic Removal
These systems are very effective at reducing pentavalent arsenic from drinking water. These models were tested
in a lab and proven to reduce 300 parts per billion (ppb) pentavalent arsenic to below 10 ppb, the USEPA standard for safe drinking water.
RO systems are not as effective at reducing trivalent arsenic from water. These models will not convert trivalent
arsenic to pentavalent arsenic. If you have free chlorine residual in contact with your water supply for at least one
minute any trivalent arsenic will be converted to pentavalent arsenic and reduced by this RO. Other water treatment chemicals such as ozone, and potassium permanganate will also change trivalent arsenic to pentavalent
arsenic. A combined chlorine residual (also called chloramine) may not convert all the trivalent arsenic. If you get
your water from a public water utility, contact the utility to find out if free chlorine or combined chlorine is used in
the water system.
Maintenance
It is strongly recommended that you follow the maintenance instructions and have your water tested periodically
to make sure the system is performing properly. See replacement element information above for recommendations on maintaining your Reverse Osmosis water filtration system.
Compounds certified under NSF/ANSI 401 have been deemed as ‘incidental contaminants / emerging compounds.’
Incidental contaminants are those compounds that have been detected in drinking water supplies at trace levels. While
occurring at only trace levels, these compounds can affect the public acceptance/perception of drinking water quality.
The system conforms to NSF protocol P231 for microbiological water purifiers. The system is not intended to convert
wastewater or raw sewage into drinking water.
Spent adsorption media will not be regenerated and used.
The system is to be supplied only with cold water.
The system and installation shall comply with applicable state and local regulations.
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 0.30 mg/L or less. This system reduces pentavalent arsenic, but may not reduce other
forms of arsenic. This system shall 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 pentavalent arsenic. Treatment with
chloramine (combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent
arsenic. Please see the Arsenic Facts section below for further information.
