COMPONENTS AND TOOLS IDENTIFICATION
Your Reverse Osmosis System has been tested to ensure it will operate correctly. The following periodic
maintenance is recommended so your system will provide years of trouble-free service:
Replacement part Frequency
Pre-filter (sediment) Every 6 mos.
Pre-filters (activated carbon) Every 6 mos.
R/O membrane Every 1-2 years
Post filter (carbon) Every 6 mos.
Components
The following components make up your Reverse Osmosis Drinking Water System:
Pre-filter (sediment) removes larger particles such as sand, silt, rust and scale.
Pre-filters (activated carbon) remove chlorine in the feed water to protect the reverse osmosis
membrane.
Reverse Osmosis Membrane reduces dissolved minerals, metals and salts. During the pro-
cess, harmful compounds are separated by the membrane and the reject water goes to waste
(drain).
An activated carbon post-filter is provided for a final “polish” and to remove foul tastes, odors
and to provide great tasting drinking water.
Filter housings and RO module hold pre-filters and membranes. A bracket is provided so they
may be mounted, typically below sink.
Storage tank holds filtered water, ready for use.
Automatic shut-o valve senses when the storage tank is full and closes the water supply to
conserve water.
The dedicated faucet is used to dispense RO produced water when needed.
Feed water valve is connected to the cold water line to supply water to the R/O system.
Waste water saddle valve is connected to the drain to remove reject water from the R/O
system.
Tubing supplies feed, reject water, and clean water.
Fittings are used for necessary hose connections
• 3/8” variable speed electric drill, 1/8” &
1/2” bits
• 1-1/4” porcelain hole cutter (if hole for
second
• Faucet is not provided
• Center punch and hammer
• 1-1/4” wood bit
• Concrete drill bits
• Phillips head and flat blade
screwdrivers
• Adjustable wrench
• Crescent wrench
• Teflon tape
• Plastic tube cutter
• Air pressure gauge (low pressure)
• Air pump (hand)
Tools
The following tools may be necessary, depending on your installation:

PREINSTALLATION
System Location
Your R/O system may be installed under a sink, in a basement or other location, depending on
available space. Do not install unit where temperatures fall below freezing; otherwise, damage will
result. Connection to an icemaker should also be considered for optimum performance.
Guidelines for component placement are as follows:
Faucet should be placed near the sink where drinking/cooking water is normally required.
A 2” flat surface is required to mount the faucet if an existing hole for a second faucet is not
available. The diameter of the hole should not exceed 1-1/4”.
Storage tank may be placed where it is convenient, within ten feet of the faucet. Under the
sink or in a nearby cabinet are excellent choices. If tank is located further than 10 feet from
the faucet, use 1/2” tubing to reduce pressure drop. Full tanks may weigh more than thirty
pounds, so a sturdy shelf is required.
R/O unit may be mounted on either side of the sink, in a cabinet or heated basement, with
nearby access to a potable, cold water line.
Feed water connection is accomplished with a feed water valve. Locate this assembly as
close to the R/O unit as possible. Connect to a potable, cold water supply line only.
Note: Softened water is preferred since it will extend the life of your R/O membrane.
Drain connection is accomplished using a waste water saddle valve which is designed to fit
around a standard 1-1/2” OD drain pipe. The drain saddle valve should always be installed
above (before) the tap and on the vertical or horizontal tailpiece.
Do not install the drain saddle valve near a garbage disposal; otherwise, plugging of the
waste water line may occur. If discharging into a utility sink or standpipe, an air gap must be
provided. (Air gaps must be 1” or greater above the floor rim.)
Do not connect the R/O system drain line to the dishwasher drain line as back pressures
may cause the air gap to overflow.
Site Preparation
Installing dealers may want to speak with customers in advance and ask them to clean under the
sink to save time. If a basement installation is advisable, check area to determine if extra fittings
or hosing are required. Upon arrival, it is a good idea to check the condition of all plumbing for
potential leaks and advise customer so there will be no misunderstandings in the event leaks
occur.
Unit Preparation
Open shipping carton, remove components and check that all parts are present. Check empty storage
tank to be sure air pressure is approximately 7 PSI.
NOTE:
Plumbing codes may require the diameter of the hole. Please check with your
local municipality.
?
NOTE:
Adjust if necessary.

INSTALLATION INSTRUCTIONS
Faucet Installation
If the sink has a sprayer it may be disconnected for faucet installation. (Installing dealers should dis-
cuss this with customers.) A pipe cap or plug will be necessary to seal the sprayer connection.
To make the faucet mounting hole (if sprayer or second hole is not used), check below to make sure
the drill does not interfere with anything below. Center punch a small indent at the desired faucet
location. (2” flat surface is required, not exceeding the chassis punch and tighten nut to cut the de-
sired hole size. Clean up sharp edges.
The faucet should be positioned so it empties into the sink and the spout swivels freely for conve-
nience. If sink has a hole that can accommodate the RO faucet, no drilling is required.
Proceed with mounting the faucet.
1
Procedures
1. Mark the center for the 7/8” hole.
2. Form shallow putty around hole area and fill with enough water to lubricate carbide drill
bit.
3. Carefully drill pilot hole through all layers. (Use light pressure and slow speed.)
4. Insert pilot tip of spring-loaded porcelain cutter into pilot hole.
5. Drill porcelain/enamel using spring loaded porcelain cutter, making certain a complete ring
has been cut through the porcelain / enamel to the metal base.
6. Cut away the inner porcelain / enamel disc down to the base metal. Make certain the
cutter does not touch outer rim of the cut porcelain / enamel. Continue with his bit to cut
through metal until sink has been completely penetrated.
PORCELAIN, ENAMEL, CERAMIC ON METAL OR CAST IRON PRECAUTIONS MUST BE TAKEN
TO PENETRATE THE PORCELAIN THROUGH TO THE METAL BASE AND PREVENT IT FROM
CHIPPING OR SCRATCHING.
!
Tools required:
• Variable speed drill
• Relton porcelain cutter tool set (7/8” or alternative size, 9/16”)
• Plumber’s putty
NOTE:
All plumbing must be completed in accordance with state and local plumbing codes.
Some municipalities may require installation by a licensed plumber. Check local authority
prior to installation.
?
NOTE:
Always use sharpened porcelain cutter to eliminate chips and cracks.
?

Mounting the Faucet
Disassemble hardware from the threaded nipple, except for chrome base plates and rubber washers.
(Rubber washers may be replaced with bead of plumber’s putty for neater appearance.)
Feed the threaded nipple through sink or counter mounting hole and orient the faucet. From below
sink or counter, assemble the white spacer flat washer and hex nut on threaded nipple and tighten
by hand. (Open end up; open side toward air gap). After checking faucet orientation, tighten with a
wrench until secure.
2. Some shut o valves have an extra port for an icemaker hookup. You will not need the
feedwater adapter for this type of installation. (See diagram A )
3. On some shut o valves you can install the feedwater adapter directly to the valve.
Slip the black washer into the feedwater adapter. Tighten feedwater adapter to the valve
with an adjustable wrench. Tighten until snug. Insert the 1/4” metal ball valve into the
feedwater adapter.
1. Turn o cold water supply to the sink using the supply valve located under the sink.

CAUTION!! For your safety and protection, do not use where water is microbiologically unsafe
or of unknown quality. The water supply to your system MUST be from the COLD WATER LINE!
Hot water will severely damage your reverse osmosis system!
!
DO NOT OVERTIGHTEN! (See diagram B )
!
NOTE:
In some cases the supply valve may leak or may not work at all. If this happens
turn o the water at the main water shut o for the entire house. In extreme cases
the house shut o valve does not work. If this happens shut the water o at the
street and replace the defective valves immediately. Locate the type of shut o
valve you have under your sink and follow that step for connecting the feedwater.
?

- 8 -
Most under sink shut o valves have a built in smooth or corrugated riser going up to the
faucet. (Refer to Diagram C for help with this type of valve.) Secure an adjustable wrench
to the fitting on the cold water side of the sink faucet -- NOT THE R.O. Faucet! Secure
another adjustable wrench to the smooth/corrugated riser line nut. Gently undo the riser line
from the sink faucet. Do not be alarmed! There will be water left in the line—this is normal.
However, if the flow does not stop you probably haven’t shut the water o properly.
4. Insert the black rubber washer into the feedwater adapter. Screw the adapter onto the fitting
coming from the cold water side of the sink faucet. Tighten the feedwater adapter to the
cold water line. Take extreme care not to twist or damage the connection to the cold water
connection.
5. Connect the riser from the water shut o valve to the feedwater adapter. Ensure that the
cone washer on the riser tube is in good condition. Connect the riser to the feedwater
adapter.
6. If your line port is 1/2 inch use the included fittings (Diagram B).
7. If your line ports are 3/8 inch remove the fittings from the feedwater adapter (Diagram C).
CAUTION!! Tightening the connector improperly to the sink faucet could cause
irreparable damage to the faucet.
!
DO NOT OVERTIGHTEN! This can cause damage to the riser connection or
feedwater adapter.

Drain Saddle Valve Installation
Prior to proceeding it is important to inspect the condition of drain pipes to make sure they are not
thin and frail.
Drain saddle valves are designed to be installed on standard 1-1/2” OD drain pipe. Install drain saddle
valve above (and before) the trap and on the vertical or horizontal tailpiece. Never install a drain sad-
dle valve close to the outlet of a garbage disposal or plugging of the RO drain line may result.
Procedures
1. Position threaded half of drain saddle valve at selected location and mark for the opening.
2. Drill 1/4” hole at mark through one side of pipe.
3. Position both halves of drain saddle on drain pipe so threaded opening lines with hole.
4. Secure drain saddle clamp on valve with bolts and nuts provided. (Do not over tighten and
make sure there is equal space between saddle halves on each side.)
3
Initial Tubing Connections
For convenience on under counter installations it may be advisable to complete under counter hose
connections at this time. (Fittings Installation Instructions on page 10)

RO Unit Installation
The RO unit is normally mounted to the right or left sink cabinet sidewall, depending on where supply
tank is to be located. Generally the unit is installed at the front of the cabinet and the tank at the rear.
To mount the unit, elevate it at least 2” o the floor, level it and mark the location of mounting holes
needed. Drill holes for mounting screws and install screws, allowing the mounting bracket slots to
slip over them.
6
Pre-fill Storage Tank and Placement
Pre-filling the storage tank is always recommended so there is sucient pressure to check for leaks
and sucient water to flush the carbon post filter.
It is important to use a sanitizer (such as Clorox) so tubing, fittings, tank and the faucet will be safe to
use upon start-up.
7
Final Tubing Connections
With all components in place, complete nal tubing connections using these guidelines:
• Tubing should follow contour of the cabinets.
• Cut tubing to desired length using square cuts
• and proper cutting devise.
• Make no sharp bends.
Keep tubing from the RO unit to the tank and faucet as short as practical for good flow.
Under sink installations following installation diagram and the following procedures:
1. Connect tubing from faucet to RO unit.
2. Connect tubing from tank to RO unit.
3. Connect tubing from supply valve to RO unit.
4. Connect tubing from drain valve to RO unit. (For Fittings Installation Instructions go
to page 9)
8
To pre-fill storage tank follow these directions:
1. Connect storage tank to feed water line.
2. Open feed water valve and valve on tank.
3. Allow to fill for approximately three minutes.
4. Turn o feed water valve and tank valve.
5. Do not flush tank for approximately 15 minutes.
The supply tank should be placed under the counter
or within 10 feet of the RO unit.
NOTE:
Tanks are pre-pressurized at 7 psi. Prior to installation, check, add or release
as required.
?
NOTE:
If the cabinet sidewalls are not solid, unit may sit on the floor with screws to keep it against
the cabinet in a vertical position.
?

- 11 -
1. Check all connections to be sure they are secure.
2. Turn on feed water valve and check for leaks.
(Turn o and correct leaks if leaks occur.)
3. Open valve on storage tank and open faucet until a steady stream of water flows.
4. Close faucet and wait five minutes to see if leaks result.
1. Open faucet handle and allow tank to completely drain of sanitizing solution.
2. With faucet handle in “open” position, measure the rate of the steady drip from spout. Use
a graduated cylinder and watch with a second hand to calculate approximate production
in gallons per day.
3. Proceed to check reject flow rate by disconnecting tubing at drain connection and mea-
sure flow as described above.
Icemaker Hookup (optional)
The RO drinking water device can be connected to any standard refrigerator ice maker or ice maker/
water dispenser. (Do not connect to a commercial type bar ice maker.)
To complete this operation, connect a tee with shuto valve into the faucet tubing and route tubing
to the refrigerator. (Hooking up to an existing copper line is not recommended unless it is new
installation.) Shut o ice maker by lifting lever prior to turning o the existing tap water supply line to
the refrigerator. Turn on ice maker after the RO system has been drained several times and the tank
has a full supply of water.
SYSTEM STARTUP
Pre-Start Instructions
Flushing and Operation Check
To make sure RO system is operating correctly, following these simple procedures:Turn on feed
water valve and check for leaks. (Turn o and correct leaks if leaks occur.)
NOTE:
When tank is empty, faucet will steadily drip. This is the rate the RO system
processes water.
?
NOTE:
Milliliters per minute x 0.38 = GPD Ounces per minute x 11.2 = GPD
?
NOTE:
Proper ratio should be 3 reject water to 1 part of product water, on average.
?
NOTE:
When the system is first turned on, water may intermittently “spurt” from the air gap
opening on the side of air gap faucets. This is common and should correct itself
after an initial period of time.
?
NOTE:
Before any service is preformed on the RO system, turn o ice maker valve and ice
maker unit. Turn back only after RO tank is full.
?
DO NOT USE THIS WATER!
!

- 12 -
4. Close faucet and re-inspect system for leaks.
5. Allow system to process water for approximately four hours, at which point tank will be
practically full.
6. Open faucet again and allow tank to empty for a second time.
7. Wait another four hours to allow tank to re-fill.
DO NOT USE THIS WATER!
!
NOTE:
If no objectionable tastes are noticed after second tank draining, RO processed
water is ready for use. Otherwise, drain tank and re-fill for a third time.
?
NOTE:

?
NOTE:
Be sure to check o-rings are in place when installing cartridges in filter housings.
?
8. At this point supply line to ice maker connection (optional) may be opened.
MAINTENANCE
Your RO system contains filters and membranes which must be replaced periodically for proper
operation. (Please see page 1 for general changeout recommendations.)
To change filters and membranes follow these procedures:
1. Close feed water valve by turning it clockwise.
2. Open faucet to allow holding tank to drain.
3. Loosen and remove filter housings using wrench provided and discard cartridges and or
membrane.
4. Wash the inside of the housings using mild detergent and soft cloth.
Thoroughly rinse all soap before reassembly.
5. Replace filter cartridges and membrane before sanitizing system.
Sanitizing Instructions
To sanitize system follow these procedures with the feed water valve closed:
1. Remove pre-filters and membrane from housings.
2. Use 5-1/4% unscented bleach such as Clorox.
3. Add one cap full (2 tsp or 10 ml) of bleach to each pre-filter housing and membrane mod-
ule.
4. Carefully re-fill housings with tap water and temporarily replace without carbon cartridge,
sediment cartridge or membrane installed.

- 13 -
DO NOT USE THIS WATER!

Water Quality
Water quality from an RO system is normally determined with a TDS Meter, which measures total
dissolved solids in water, measuring conductivity. The results are normally measured in parts per million
or milligrams per liter. Fewer dissolved solids results in higher quality water.
RO membranes are rated by the amount of dissolved solids they reject expressed as “rejection
percentage”.
For example:
If feed water contains 100 ppm of dissolved solids and the product water after the membrane has 10
ppm of dissolved solids the rejection rate is 90%.
5. Slowly open the feed water line at faucet.
6. Close faucet as soon as water begins to
drip out of spout.
7. Let system stand for approximately 15 minutes.
8. After fifteen minutes do the following in order:
• Close feed water valve.
• Close holding tank valve while faucet is open to release pressure.
9. Remove housings and empty them.
10.Remove any protective wrap from pre-filters and membrane and install them in the appro-
priate filter housings. Tighten with wrench.
11. Replace post carbon filter if necessary.
12.Disconnect product water tubing from the holding tank and put 50 drops of bleach into
the tubing. Reconnect tubing.
13.Slowly open feed water saddle valve. When water begins to drip from faucet, close faucet
and open holding tank valve.
14.Do not open faucet for at least eight (8) hours.
15.Discard the first two tanks of water produced, as they contain chlorine.
16.When faucet is first opened, air and black carbon powder may be noticed. This is normal.
The formula is as follows:
Percent
Rejection =
(Feed H2O TDS - Product H2O TDS) x
100%
Feed H2O TDS
NOTE:
Be sure to check o-rings are in place when installing cartridges in filter housings.

Water Production
Product water rate
Usable water production from an RO system is designated product water rate, produced on a daily
basis. The rate is normally described in gallons per day (gpd) or milliliters per minute (ml/min).
Reject water rate
The flow of water to drain is designated as reject water rate, as measured in gallons per day (gpd) or
milliliters per minute (ml/min).
Water Pressure and Temperature
Product water quality and production of RO systems is dependent on pressure and temperature.
Typically, RO membranes are treated at standard conditions of 77°F (25°C) and 60 psi (4 bar)
discharging to atmosphere. In general, the higher the pressure dierential and temperature, the
greater the quality and quantity of water produced. These factors should be considered when sizing
RO systems for a particular application.
Reject ratio
The reject ratio is the amount of water produced compared to the amount of water flowing to drain.
Percent recovery
The percent recovery is another way to measure the amount of water produced compared to the
amount of water which is actually used.
The formula to determine percent recovery is as follows:
Using a graduated cylinder the formulas are:
Milliliters per minute x 0.38 = gallons per day
Ounces per minute x 11.2 = gallons per day
The formula is as follows:
Reject Ratio =Reject Rate
Product Rate
Percent
Recovery =Product H2O Rate x 100%
Feed H2O Rate
For example:
Product water rate =10 gpd
Reject water rate = 40 gpd
Feed water = (10 gpd + 40 gpd) or 50 gpd
Percent Recovery = 20%
NOTE:
Product water rate is the sum of the feed water
flow rate and reject water flow rate.
