Things to remember!
=It will take time before water is available at the
faucet. It may take 1-4 hours before maximum
possible flow is available from the faucet.
=Water pressure from the Reverse Osmosis faucet
will be less than your standard faucet due to the
high level of filtration performed by the system.
=The faucet can be mounted in an existing hole in
the sink (sprayer, soap dispenser etc.) or a new
hole can be drilled.
=Water will run to the drain while the Reverse
Osmosis system is producing purified water, even
if you are not drawing water from the faucet. You
may hear a small quantity of water going to the
drain whenever the system is producing purified
water. Water going to drain will automatically
shut off when the storage tank is full.
=This unit can be installed remotely (basement,
mechanical room) or under the sink.

Performance Data
Reverse Osmosis Water Filtration System
Model WHAROS5
IMPORTANT NOTICE: Read this performance data and compare the capabilities of this unit with your actual water
treatment needs. It is recommended that, before purchasing a water treatment unit, you have your water supply
tested to determine your actual water treatment needs. This filter system is designed to be used for the reduction of
the substances listed below. Do not use where water is microbiologically unsafe or of unknown quality, without ade-
quate disinfection before or after the system. Systems certified for cyst reduction 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 280 kPa (40 psig) or greater. 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 on page 8 for further information. While testing was performed under standard laboratory conditions, actual
performance of this system may vary based on local water conditions. Some or all of the contaminants reduced by
this unit may not be in your water supply. See elsewhere in this owner’s manual for further instructions on filter
replacement, system installation, operating procedures, and warranty. The maintenance instructions must be fol-
lowed for the product to perform as indicated below.
General Information
This product is an undercounter system that filters and stores quality drinking water ready for use. It contains a car-
bon sediment filter, RO membrane, and an activated carbon post filter. The faucet indicator monitors the length of
time the filter has been installed and will flash amber continuously; indicating the filters and battery need to be
replaced. This system has been tested according to NSF/ANSI 58 and 42 for reduction of substances listed below.
The concentration of the indicated substances in water entering the systems were reduced to a concentration less
than or equal to the permissible limit for water leaving the system, as specified in NSF/ANSI 58. The testing was
performed using spiked chlorine free deionized water with ≤1 NTU turbidity, 7.5 ± 0.5 pH, 25 ±1°C, and 1µS/cm con-
ductivity.

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. nvironmental Protection Agency
(US PA) 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 US PA stan-
dard 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 treat-
ment 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 recommenda-
tions on maintaining your Reverse Osmosis water filtration system.

Osmosis inlet
Check and comply with local plumbing codes as you plan,
then install a cold water supply fitting. Refer to the
Specifications page for supply water requirements. The fitting
must provide a leak-tight connection to the RO 1/4" tubing. A
typical connection using the included water supply fitting is
shown in Figure 6.. An optional connection using standard
plumbing fittings (not included) is shown in Figure 7.
NOTE: Local code may dictate which type of water fit-
ting is used. Consult a plumber if you are not familiar
with local codes or plumbing procedures.
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 plumb-
ing code 248-CM of the Commonwealth of
Massachusetts before proceeding with the installation.
INSTA CO D WATER SUPP Y 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 over-
tighten.
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.
OPTIONA 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 7. 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
to choose from:
• Install the Drain Adaptor included with your unit
See Fig 8, Fig. 9, and Fig. 10. This is used in under
the sink installations. The drain adaptor kit is
installed onto your sink drain pipe above the P-trap.
See Fig. 8.
• Use another existing drain in your home
(See Fig 11 & 12) This is usually used in remote
location type installations. The drain tube from the
Reverse Osmosis Filter runs directly to an open
drain. See Fig. 11 & 12.
NOTE: An incorrectly connected drain point can
cause water to leak from the faucet’s air gap.
NOTE: Local code may dictate which type of drain
installation is used. Other than local code, either
drain install type may be used in both under the
sink or remote location installations. Consult a
plumber if you are not familiar with plumbing pro-
cedures.
INSTA DRAIN ADAPTOR KIT
(Under sink Installation)
A drain adaptor kit is included in your package. Review
the drain adaptor kit parts in Fig. 9. Install the drain
adaptor above or ahead of the P-trap. See Fig. 8 & 10.
Be sure to comply with your local plumbing codes. The
drain adaptor fits 1-1/2" sink drain pipes. Other drain
pipe fittings, purchased locally, may be needed in addi-
tion to the adaptor.
1. Slowly disassemble the sink drain pipe between the
sink P-trap and the sink tailpiece. See Fig. 8 & 10.
2. Clean the sink tailpiece to assure a leak-tight fit.
3. Install drain adaptor directly onto the sink tailpiece
using the ferrule and nut. Snug the nut, but do not
tighten. See Fig. 9.
4. Assemble the drain tubing connector to the drain
adaptor using the ferrule and nut. Snug the nut, but
do not tighten. See Fig. 9.
NOTE: Locate so that the drain tubing from the
everse Osmosis faucet will run straight to the
adaptor, with no dips, loops, or kinks. See Fig. 10.
5. Turn the connector to about 45° (10:00 or 2:00
position). See Fig. 9. Tighten the nut securely.
6. Assemble the P-trap to the drain adaptor, and other
drain pipe fittings as required to complete the drain
run. See Fig. 8.
NOTE: If needed, you can cut the unthreaded
end of the adaptor to make it fit. Do not cut too
short or the adaptor will not make a leak-tight
seal with the connecting fitting.
7. Tighten all connections, but do not over tighten plas-
tic connections.

Step B - Install RO Drain in Remote Location
INSTA A REMOTE DRAIN POINT AND
AIR GAP (Remote ocation)
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. 12. This type of
drain is the preferred over the p-trap drain adaptor.
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.
To install a remote drain point, complete the fol-
lowing steps:
1. Locate the 1/4” red tube and determine whether it is
long enough to reach from the Reverse Osmosis fil-
ter assembly to the drain point . See Fig. 11.
2. If longer tubing is required, see parts list in back of
manual and replace the red tube with an adequate
length 1/4” tubing.
3. Cut one end of the drain tube square. See Fig. 17.
4. Insert this tube all the way into the red collet fitting on
the Reverse Osmosis filter assembly. See Figs. 18, 19
& 22.
5. Pull on the tubing to be sure it is held firmly in the fit-
ting.
NOTE: A flow control insert is located inside the
elbow fitting that the drain tube connects to.
efer to Fig 27. Leave this fitting in place.
6. Route the tubing to the drain point and secure at the
end with a bracket (not included). See Fig. 12.
Provide a 1-1/2” air gap between the end of the tube
and the drain. See Fig. 12.

Step D - Install RO Faucet
INSTA STORAGE TANK
1. Apply Teflon®tape (2 wraps clockwise) to the
threads on the nipple at the top of the tank. See Fig
13.
2. Locate the tubing connector. See Fig. 13. Slowly
tighten the tubing connector onto the tank nipple 7-8
full turns, so as 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.

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 1-3/8” 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 1-3/8" diameter hole in
the mounting surface.
IMPO TANT: 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 sur-
face materials such as granite, marble, Corian™
or other plastic resin products or sinks made of
porcelain or stainless steel may cause perma-
nent, irreparable damage to the sink or counter-
top surface.

already connected to the faucet. Insert these tubes into
the sink hole until approximately one foot of tube length
and the faucet body are left above the counter surface.
Do not kink the tubes in the process. See Fig. 14.
NOTE: If you are going to route the red drain tubing
directly to a remote drain point (see page 14), skip steps
8-11, and proceed to step 12.
8. Route the loose end of the 1/4” red tube up through the
countertop to faucet. See Fig. 22.
9. Cut tube square and to length. See Fig. 17.
10. Insert all the way onto the 1/4" faucet barb fitting on
faucet. See Fig. 16.
11. Pull on the tubing to be sure it is held firmly in the fitting.
12. Mount the faucet body onto the faucet base, 1/4 turn.
FAUCET E ECTRONICS
Inside the faucet base is a battery operated 6 month timer.
An amber L D indicator is also located in the front of the
faucet base. This L D will flash continuously after 6 months
has passed. This indicates that it is time to replace the
battery, prefilter and postfilter.
INSTA BATTERY
To install battery, complete the following steps.
1. Remove the screw on the right side of the faucet base.
2. Press the battery housing upward from the front faucet
base until it releases from the faucet base. See Fig. 15.
3. Install the battery (CR 2032 or equivalent). Place battery
into the holder with the positive (+) side facing the back of
the holder.
4. When the battery is installed the L D will flash six times
and turn off. This indicates the battery is fully charged.
After the six flashes, the timer enters the 6 month time
cycle.
NOTE: If the LED repeatedly flashes two times, the
battery needs to be replaced.
5. Re-install the battery housing and firmly tighten the mount-
ing screw. See Fig. 15.

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 wash-
ers 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
1. Push tubing through collet, until it engages the o-
ring. 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.
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.
2. Continue holding collet inward while pulling the tub-
ing out. See Fig. 21.

SANITIZE THE SYSTEM
Sanitizing is recommended immediately after installa-
tion of the Reverse Osmosis system. It’s also recom-
mended 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 the eyedropper included in parts bag and
common household bleach (5.25%).
4. Add 3 ml. of bleach into open end of yellow tube.
Handle bleach according to bleach manufacturer’s
recommendations. See Fig. 23.
5. Connect yellow tube to tank connector. See Figs. 13
and 22.
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 sys-
tem before drinking the water. See purging instruc-
tions 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 sev-
eral 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 O 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 appar-
ent. echeck 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 per-
mit the use of saddle valves.
If you live in the state of Massachusetts, review
plumbing code 248-CM of the Commonwealth of
Massachusetts before proceeding with the installa-
tion.
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 O sys-
tem until purging is complete.
2. Close the Reverse Osmosis faucet after the 24 hour
purging period is complete.
3. 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.
