IMPORTANT WARNING - PLEASE READ
System Flushing: This reverse osmosis system contains a preservative solution to prevent
microbiological growth and freezing which if ingested may cause irritation of the
gastrointestinal tract, colic, diarrhea or other symptoms. Therefore, approximately 5
gallons of water must be drawn from the tap to flush out the preservative solution before
using the system. This volume of water represents approximately two days of production.
The water flushed should be disposed of to the drain.
Feed Wate Quality: This reverse osmosis drinking water system is not intended to be
used for the treatment of water that is microbiologically unsafe or of unknown quality. If
the feed water quality is unsafe or unknown, have a sample of the water tested by a
qualified laboratory or agency and implement the necessary measures to ensure a safe

INTRODUCTION
Congratulations, on the purchase of your new Reverse smosis Drinking Water System. Treated with care
and regular maintenance, your new system will provide many years of service delivering purified water to
the tap.
By now, you have probably already opened the box to survey the contents. Please take a few moments to
review this manual before proceeding with the installation and use of the system. Some important items
to review are as follows:
• Check all components for any damage caused in shipment. Also, take a quick inventory of
all items supplied to ensure none are missing. A checklist in the next section will assist you
with identifying these items.
• Ensure that the reverse osmosis system and storage tank will easily fit into
the desired location. This reverse osmosis system and tank needs to be removed for
regular maintenance, so good accessibility is an important tip to keep in mind.
• Read all warnings contained within this manual.
Although this product is described as a ‘Drinking Water System’, the purified water produced by the
reverse osmosis (R ) process can be used for many purposes around the home.
•Drinking Water - keep container of R water in the fridge to be able to enjoy the clean,
fresh taste. Alternatively, take it directly from the tap.
•Ice Cubes - use R water to fill ice cube trays. Ice cubes made from R water are typically
clearer and better tasting than ice made from plain tap water.
•Automatic Ice Makers - a water line from the R system can be plumbed to refrigerators
with automatic icemakers. Additional accessories required to complete this connection are
not included. Please consult the refrigerator’s owner’s manual on this installation.
•ettles and Coffee Makers - plain tap water eventually causes films and scale in these
devices that is difficult to clean. R water is very low in dissolved minerals content, greatly
reducing the chance of scale buildup.
•Cooking - use R water for boiling pasta, rice or any other recipe that calls for water in
the instructions.
•Washing Fresh Fruit & Vegetables - prevent tap water minerals from being deposited
onto food to maintain freshness.
•Family Pets - Allow you dog or cat to enjoy the same purified water you do.
•Irons, Steamers & Humidifiers - prevent mineral buildup in household appliances that use
water and eventually build up with scale when using plain tap water.
Now you can relax and enjoy the benefits of great tasting water supplied by your reverse osmosis drinking
water system. Remember that good quality water is important to maintaining a healthy lifestyle. You can
also feel good about the money you have saved by installing your own drinking water system instead of
dealing with the expense and hassle of bottled water delivery.

Application Guidelines
(1) Nominal product water ratings are based on the following conditions: Supply TDS of 250 ppm softened tap water, 50 psi (0.36 Mpa), 77oF (25oC), pH
8 and 15% recovery with outlet to atmosphere.
(2) Rejection percentages are dependent on the supply conditions and the substance being measured.
Notes:
The performance of a reverse osmosis membrane is highly dependent upon pressure, temperature and TDS. The actual volume of product
water and rejection percentage will vary with differences from the test conditions that membrane ratings are based upon.
These drinking water systems are not intended to be used for the treatment of water that is microbiologically unsafe or of unknown quality..
Functional Description
Feed water enters the 5-micron pre-filter (combination 5 micron/carbon filter in 2 sump models), which
filters out suspended particles such as dirt or sediment. The filtered water then enters the pre-carbon filter
( in 3 sump models only), which contains granular activated carbon, which removes any chlorine from the
water. The two sump models utilize a combination 5-micron/carbon filter to filter fine particles and remove
chlorine.
Model D75TFC-3 only: Water from the pre-carbon filter enters the scale inhibitor filter. This filter inhibits
the formation of scaling deposits on the surface of the membrane, providing better protection and longer
membrane life.
The water then enters the reverse osmosis membrane. The membrane will allow only permeate (pure
water) to pass through. The brine (waste water) goes to the drain.
Permeate then flows through a hydraulic shut-off valve to the storage tank. When the tank fills and the tank
pressure reaches 2/3 of the inlet feed water pressure, the shut-off valve closes, which turns the system
off.
When water is drawn from the faucet, permeate flows from the storage tank through the post carbon
filter. This filter contains granulated activated carbon, removing any taste and odor that has accumulated
while stored in the tank. When the tank empties, the shut-off valve opens, turning the unit on.

Installation
All State/Provincial and local government codes regarding installation of these devices must be
observed.
Verify Water Supply is Potable
The water supply must meet provincial/state and/or national standards for potable drinking water. Water
samples should be sent to a certified laboratory for analysis.
Placement of Components
Placement of the various components of the system will vary from installation to installation. The main
objective is to place the components so that they are accessible for servicing and ease of installation.
Spigot
Proper spigot placement should ensure a no-splash waterfall pattern into the sink. The spigot handle
should be positioned to either the left or right as one faces the sink.
Storage Tank
The storage tank should be placed so that it can be easily removed from under the sink. Avoid placing
the storage tank in out-of-the-way cabinets or dead spaces. There are two reasons for this: 1) the
difficulty of installation increases significantly and 2) when the storage tank is located further away from
the spigot, the flow rate diminishes.
Module Assembly
The module assembly should be hung on a sink cabinet side-wall with the two wood screws provided.
Quick Connect Fittings
All connections are quick connect fittings except for the two slip-on barbed tubing connections on the air
gap spigot (optional).
To Prepare Tubing
•Cut the tube squarely and remove any burrs.
•Mark from the end of the tube the length of insertion. (1/4" .D. - 11/16", 3/8" .D. - 3/4")
To nsert Tubing into Fitting
•Insert tube straight into fitting until it bottoms out on interior shoulder and insertion mark is no longer
visible.
To Release Tubing
•Push collet toward body and pull on tubing to release tube. To re-use fitting, begin assembly over
again.

d. Pierce the copper tubing by turning the needle valve handle (clockwise) until it is firmly seated. The
valve is closed in this position.
e. Turn on main supply valve to pressurize cold water line. Immediately check for any signs of leaks.
f. When ready to supply water to the system, turn valve handle (counter-clockwise) until fully open.
Feed Water Assembly
Installation of Drain Saddle Assembly
The system comes supplied with a drain saddle and mounting hardware which fits around a standard 1½"
.D.drain pipe (See Figure 6).
a. The saddle should be installed above the trap and on the vertical or horizontal tailpiece. It should never
be placed close to the outlet of a garbage disposal (See Figure 7).
b. Position saddle assembly on drain pipe to allow adequate space for drilling through pipe. If possible,
angle the drain saddle fitting toward spigot location.
c. Tighten the drain saddle screws evenly and firmly so a good seal is made. Avoid over tightening.
d. Drill a 5/16" hole in the drain pipe through the drain fitting opening. Support the drain against drilling
pressure.
e. Insert black drain line tubing into compression nut and tighten.
Figure 5a Figure 5b

Installation of Ball Valve Assembly
The ball valve and quick connect adapter must be installed on the R storage tank.
a. Put 2-3 wraps of Teflon tape on the storage tank threads, and on the ¼" x 3/8" male connector.
b. Install the ¼" x 3/8" male connector onto the ball valve. Tighten the fitting very gently until it is snug.
Be very careful not to over-tighten or the threads may strip.
c. Tighten the ball valve assembly onto the R storage tank. Tighten the fitting very gently until it is snug.
Be very careful not to over-tighten or the threads may strip.
Drilling Sink Hole
The typical 1-1/8"" sink hole will accommodate most standard or air gap spigots. nce the location of the
spigot has been determined, always check below the point you are about to drill to ensure it is
unobstructed and that it isn't over a reinforcing rib.
a. Center punch the desired location to provide a starting point for your drill.
b. Drill a 1/8" pilot hole.
c. Enlarge the pilot hole using a 1-1/8" high speed steel hole saw for air gap faucet.
d. Enlarge the pilot hole using a 9/16" drill bit for standard faucet.
e. Remove all burrs and sharp edges.
f. Immediately clean up the sink area.
N TE: If an enamel or porcelain sink is encountered, it is very important that the layer of porcelain be
removed before following the steps outlined above. This can be accomplished by gently grinding away,
using a hobby grinder and silicon carbide wheel, enough area of porcelain down to the metal base to
accommodate a 1-1/8" high speed steel hole saw. The hole saw cannot contact surrounding porcelain or
chipping can occur. Now the steps outlined above can be followed.
Installation of Air Gap Faucet
1. Place the chrome washer and the rubber washer on the base of the faucet.
2. Apply 5-7 wraps of the teflon tape to the bottom of the brass stem. Install 3/8" quick connect faucet
adapter provided. Tighten gently until fitting is snug. Be careful not to over-tighten as the threads may
strip.
3. Attach the ¼" brine water discharge line to the brine input (small) barb and ¼" or 3/8" drain line to the
brine output (large) barb.
4. Mount the faucet and complete assembly.
Note: Before connections are made, tubing should be cut to ensure a neat and orderly installation. The
storage tank and spigot tubes should be as short as possible so that the greatest possible flow can be
obtained from the spigot.

Start-Up Procedure
WARNING: To prevent microbiological growth and freezing, this reverse osmosis system contains a
preservative solution which, if ingested, may cause irritation of the gastrointestinal tract, colic, diarrhea
or other similar symptoms. Therefore, 5 gallons (approximately two full tanks) must be drawn from
the spigot to flush out the preservative. This may represent two or three days of running, depending
on conditions of the feed water.
The carbon filters require some rinsing to remove carbon fines. The filters will rinse out on their own by
allowing the system to produce 2 full tanks of water and discarding the R product water. The following
procedure may be followed if it is desired to rinse the filters immediately before producing an R product
water.
a. Disconnect the green line from the auto shut off valve that runs from the outlet side of the Pre-Carbon
Filter to the Auto Shut ff Valve. Direct tubing into a pail or catch basin.
b. Turn on the feed water by opening the needle valve on the feed water saddle valve and catch the
water in the pail. The water rinsing the filter will appear grayish until the fines are rinsed out. When
the water returns to clear, close the needle valve. Re-connect the green tubing back into the Auto Shut
ff Valve. The filters are now rinsed.
c. Turn on feedwater by opening the needle valve. Immediately check for any signs of a leak. Correct
any problems if necessary. Turn on storage tank valve.
d. It will not be uncommon to experience air bubbles or dissolved air in the product water. This will
disappear after the unit is in service for a short period of time.
e. The first two full tanks must be discarded to flush the membrane preservative out of the system as well
as flush the carbon fines from the Post Carbon Filter.

Maintenance Schedule
This schedule is designed for the average potable water supply and should be followed to ensure the
proper functioning of your drinking water system.
Pre-Filter - The pre-filter contains a 5 micron mechanical filter element. Its function is to remove
suspended particles from the feed water, thus reducing the possibility of clogging the reverse osmosis
membrane. The pre-filter element should be replaced every twelve months or earlier depending on the
quality of the feed water.
Pre-Carbon Filter -The pre-filter contains a granular activated carbon. Its function is to remove
chlorine from the incoming water to prevent any damage to the TFC membrane. The Pre-Carbon filter
cartridge should be replaced every 24 months.
Scale nhibitor (‘D’ models only) - The scale inhibitor in-line feeder contains polyphosphate
crystals. Its function is to keep calcium salts in suspension, thus reducing the scaling effect on the reverse
osmosis membrane. The scale inhibitor feeder should be replaced every 24 months.
Combination Five Micron Pre-Filter and Carbon Filter - Removes tiny particles of
suspended dirt, sediment and organics, while protecting TFC membrane from chlorine. This filter should
be replaced every 12 months.
Reverse Osmosis Module - The reverse osmosis module contains a semi-permeable membrane.
Its function is to separate water molecules from dissolved impurities in the feed water. This is
accomplished by application of hydraulic pressure greater than the osmotic pressure in water containing
dissolved solids. The life of the membrane can be determined by measuring the percentage of rejection
of total dissolved solids in the water. The membrane should be replaced every 24 to 36 months when its
efficiency will decrease.
Toxic Contaminant Removal Filter (‘D’ models only) - The toxic contaminant removal in-line
filter contains a granular activated carbon. Its function is to absorb a percentage of the toxic contaminants,
(e.g. trihalomethanes, herbicides, pesticides, polychlorinated biphenyls, etc.) present in the water supply.
The toxic contaminant removal filter should be replaced every 24 months.
Post-Carbon Filter - The post-filter contains a granular activated carbon. Its function is to remove any
taste and odor from the water prior to delivering it to the spigot. The post-filter cartridge should be replaced
every 24 months.
Changing Filters
mportant: This RO System contains filters, which
must e replaced at regular intervals to maintain
proper performance. See Maintenance Schedule for
the recommended interval for changing the filters.
Local conditions may dictate more frequent cartridge
replacement. Use a drip pan to catch any water that
may spill when the housings are removed. Use only
factory approved filters.
1. Close the saddle valve by turning fully clockwise
and open the faucet by lifting the handle. Allow
storage tank to empty.
2. Loosen and remove the appropriate filter
housing(s). Discard the cartridge(s).
3. Wash the inside of the housings using a mild detergent and a soft cloth. Do not use abrasive cleaners
or pads. Thoroughly rinse all soap from the housing before re-assembly.

Sanitization Procedures for your Reverse Osmosis System
Sanitization is a simple but important part of a regular maintenance routine required to keep your Reverse
smosis Drinking Water System operating properly.
Recording the dates of all maintenance and sanitization done on the unit is a good idea as well as marking
on your calendar future service interval dates. Your water system installer may have a maintenance
service program to deal with cartridge replacement and system sanitization by setting up regular
scheduled service calls.
Sanitization maintenance of the Reverse Osmosis Drinking Water System should be performed:
• Upon installation
• At least every 6 - 12 months as part of a regular maintenance routine.
• Whenever the pre-filter and post-filter cartridges are replaced as part of a regular maintenance routine.
• Whenever the reverse osmosis membrane is replaced.
• After the system requires any servicing or routine maintenance by your local water treatment
specialist.
• After long periods of time when system is not used (approximately 30 days or more)
• Whenever evidence of harmful bacteriological contamination of the system has been discovered. In
this case contact your local water treatment specialist to disinfect your reverse osmosis system, and
identify and eliminate the source of contamination.
Materials required for Sanitization of the Reverse Osmosis Drinking Water System:
• Mild soap solution to clean various components. Soap used should be as basic as possible and not
contain any fragrances or additives.

DISINFECTANT S LUTI N)
• Drip pan or catch basin to collect any solution or water spilled along with paper towels to cleanup any
spills.
• Silicone Based Lubricant to apply to -Rings. (D N T USE PETR LEUM BASED LUBRICANTS)
Available tem # 13691 - 60 gram vial (Certified ANS /NSF 61, FDA Registration No. 21 CFR 715.300)
Other important requirements of note:
• Before beginning installation and/or sanitization procedure, make sure that all tools used are
disinfected.
• Thoroughly wash hands with soap before beginning installation and/or sanitization procedure. If your
hands come into contact with any unsanitary surface while performing this procedure or the
installation, hands should be rewashed with soap.
• Any surfaces used to work with to set various components on to dry, should be cleaned and
disinfected.
• Any replacement cartridges, membranes and cleaned components should be handled as little as
possible.
• A new pair of latex or surgical type gloves may be used to perform any sanitization procedure, but
also be aware that if the gloves surface comes into contact with any unsanitary surface while
performing this procedure or the installation, the gloves should also be re-disinfected or replaced.
IMPORTANT: This Reverse Osmosis Drinking Water System should not be used on any water
supply sources that are microbiologically unsafe or of unknown quality without adequate
disinfection before and/or after the system.
