Dispenser/Faucet Q & A - Reverse Osmosis

Spout pulls out from faucet body that’s why it swivels. Spout has 2 o-rings at base and is inserted completely

into bottom of body to prevent leaking. Handle and tip can also be removed

Q: I do not want to drill any extra holes or use a separate dispenser/faucet - what can I do?
A: Nothing. Reverse osmosis systems are limited to a separate dispenser.

WARNING: These systems manufacture a limited amount of water and therefore the connection to the

cold side of your sink faucet is an unavailable option. In addition, the water produced by a
reverse osmosis system is aggressive and would have adverse leaching effects on any
other metals (ie: brass, copper) other than stainless steel.

Note: Drinking water filtration systems are pass through systems and will allow this option. There

will be a diminishment in your flow rate to the cold side of the faucet (kitchen faucet has a
flow rate of up to 2.3 gallons per minute and the filtered water is delivered up to 1 gallon per
minute). To get filtered water you must be sure you have the faucet to the cold side only.
This application or option is not applicable for reverse osmosis systems.

Q: I would like to use another dispenser/faucet?
A: Based on many styles and finishes, a consumer may have another dispenser they would like to use.

No problem, all these items have universal or industry standard fittings, or if not, can be easily adapted to fit.
Always check with manufacturer for proper specifications.

Note: EWS, Inc. includes a standard chrome, long-reach, lead-free faucet with white tip, handle and

optional air gap adaptor . Be aware - an air gap may be code and required with a dispenser/
faucet installation.

Options: EWS provides the following options to match other items at an additional charge;

Change your white tip and handle to black
Change your white air gap adaptor to black
Change your faucet to the following finshes; white faucet (with white tip, handle and air gap),
satin nickel, polished nickel, polished brass, or oil rubbed bronze (all with black tip, handle and
air gap). Inquire with your local EWS, Inc. distributor, cont act an authorized internet distributor
or visit us on the web (see page 4.2-25 for more details).

Q: Can we connect the filtered water up to other devices?
A: Yes, simply connect by a “T” connection, the filtered water line to any instant hot, chiller, ice-maker,

refrigerator, etc. Regarding flow rate, be mindful of too many (3 or more) connections. Also, any length of total
tubing in excess of 20 feet combined to tank, faucet, and all items may create issues with delivery rates**.
See our Point of Entry , Whole Home Appliances to filter all the fixtures within the home.

WARNING: Reverse osmosis may have warranty or restrictions with other devices, consult with other

manufacturer’s product information.

Note: **Tubing in excess of 20 feet is calculated by adding the length of tube from unit to tank

(yellow tubing) and the faucet outlet on unit to dispenser or other device (blue tubing). EWS,
Inc. supplies 5 feet of each type of tubing.

Q: Do I need to use the air gap adaptor?
A: Y es, if local code requires that an air gap be used. Since the unit is both connected to a pot able water

supply and a drain, some code requires an air gap to prevent cross-contamination, similar to all
EWS point of entry systems, a dishwaher and/or washer machines. Care has to be taken with this
unit to make all the proper connections. Follow all local plumbing codes.

Placement or Locating Dispenser/Faucet - Reverse Osmosis

Step by step instructions to mount and secure the supplied dispenser/faucet

Professional Installation is Strongly Recommended

Step 1: Locate Faucet Parts Bag

Parts Included: faucet body with handle, faucet spout with tip, decorative washer, black rubber

washer, white beveled washer, lock washer, hex nut, 1/4” tube insert sleeve,
1/4” plastic compression ferrule, 1/4” compression nut

Included flat white washer (for use under decorative washer depending on hole/application)
Optional Parts: air gap adaptor (white) for use with RO air gap applications

Preferred - Select a standard sink location to mount the faucet.

It is recommended that the faucet be placed in a hole provided on most sinks similar to the ones used for a
sprayer, soap dispenser and/or dishwasher air gap. If the hole or sp ace is unavailable, an alternative location
will be required: NON-AIR GAP: MINIMUM HOLE REQUIRED 1/2”, MAXIMUM 1 3/8”

AIR GAP: MINIMUM HOLE REQUIRED 1 1/4”, MAXIMUM 1 3/8”

Option A: On the sink. This option is to drill a new hole into the sink rim itself, if space allows.
Option B: On the countertop next to a sink. This option is to position the faucet spout in the

correct location to drain into the sink. This requires a clearance around the faucet
both above and below the countertop. Use the supplied dispenser as a template or
see the enclosed dispenser schematic and dispenser dimensions.

Prepare to drill the hole using the dispenser as a template.

• Sinks can be made of, but not limited to, stainless steel, copper, porcelain/steel, enamel/cast iron,
man-made surfaces, stone, concrete, and/or materials known or unknown at this time.

• Countertops can be made of, but not limited to, or be a combination of, natural stone, enamel,
porcelain, concrete, wood, metals and/or man-made materials known or unknown at this time.

CAUTION: Please consult with the sink or countertop manufacture, supplier, fabricator, or

installer for proper drilling techniques and methods.

EXTREME CARE MUST BE T AKEN IN DRILLING THE HOLE FOR ANY SURF ACE. THE SURFACE MA TE­RIALS OF SINKS AND COUNTERTOPS CAN CHIP OR CRACK. THE MANUFACTURER ASSUMES NO

Basic Inlet Supply Water Connection **

Professional Installation Using a Preferred Connection is Strongly Recommended

**This unit is supplied with a saddle tapping valve and should be considered a basic connection for copper , steel or brass

3/8” to 1/2” O.D. pipe prior to the angle stop shut-off of the cold water line to the kitchen faucet. This should be considered

a “do-it-yourself” connection which is not applicable in many situations and may not meet local codes.

A qualified plumber should choose to make the inlet supply water connection by a more preferred method.

Instructions from the bag containing the supplied saddle tapping valve, if applicable

Step 1: From parts bag locate: saddle tapping valve and 4’ of 1/4” tubing, color coded: red or orange (supply line to unit).

Step 4: Loosely assemble saddle tapping valve on pipe
A: For all 3/8 O.D. pipe, use side of bracket with side projections

toward or against pipe to prevent distortion of tubing.
B: For all 1/2 O.D. pipe, use “V” side of bracket with that notch
toward or against pipe.

Step 5: T ighten screws evenly . Make sure brackets are parallel,

then tighten firmly until the valve is not moving on the pipe.

CAUTION: Do not over tighten fittings.

Step 6: Connect the 1/4” plastic tubing to the saddle tapping

valve by following these instructions:
A: Slide 1/4” compression nut over plastic tubing with threads toward the
saddle tapping valve.
B: Slide 1/4” plastic ferrule over plastic tubing with long tapered side
toward saddle tapping valve.
C: Place 1/4” brass insert sleeve into the end of the 1/4” orange/red
plastic tubing.
D: Insert orange/red tubing into saddle tapping valve. Leave other end
available for system interconnection

E: Tighten compression nut onto saddle tapping valve.

Step 7: Be sure the packing nut is tight, then turn the handle of the saddle tapping valve clockwise

until it is firmly seated. NOTE: For Copper Pipe - the pipe is now pierced.

HINT: Back the end of the piercing lance out, turning the handle counter-clockwise. Then re-insert by turning the handle

of the saddle tapping valve clockwise until it is again firmly seated. This will clear any possible debris that can
block piercing lance and water flow.

Step 8: Turn the handle counter-clockwise to open the valve for water supply . Keep main line shut of f and proceed with
the remainder of the installation and start-up.

Step 2: Locate cold water line that feeds your existing faucet. Determine if there is enough
space to install the saddle tapping valve on the hard line between the wall and the angle
stop.
CAUTION: USE ONL Y COLD WATER LINE. NOT INTENDED FOR SUPPLY BY HOT
WATER.

Step 3: Shut off the main water supply to the house and open the faucet to relieve water
pressure in the hard pipe. NOTE: Shutting the angle stop only , still leaves water in that pipe.
Shut the main supply .
CAUTION: Do not turn valve handle before or while installing the “saddle tapping valve”.
Make sure the piercing lance does not protrude beyond the rubber gasket. Failure to do this
may result in damage to the piercing needle.

NOTE: For Copper Pipe - go directly to #4.

For Steel or Brass Pipe - follow A, B, C below, then go to #4

A: Drill a 3/16” hole in pipe. Use a hand drill to avoid shock hazard.
B: Turn handle to expose lance beyond the rubber gasket no more than 3/16”.
C: Place body of valve over hole so the lance fits into the hole

CAUTION:

Do not over
tighten fittings.

Preferred Inlet Supply Water Connection - All Applications

Professional Installation Using a Preferred Connection is Strongly Recommended

A qualified plumber should choose to connect the inlet supply water supply by a more preferred connection. ***

The Preferred Inlet Supply Water Connection is Applicable in All Applications and Codes

Replace the Angle Stop with a Proper 3-Way Fitting:

There are a number of options to properly install any one of these drinking water filtration systems.

Identify the cold water supply line and then you will need to know;

• Size or O.D. diameter of pipe or tubing

• Pipe material (hard or sof t copper, steel, brass, stainless, PVC, plastic, etc...)

• The existing angle stop or fitting will assist in determining the proper 3-way angle stop or fitting needed for

your specific application

4.2-9

A more preferred method to connect the inlet supply line is to shut off
the water main and replace the entire angle stop. This will have a con­nection from the house main water line, a connection to the cold water
side to the kitchen sink faucet and a much better connection for the
inlet supply to the filtration unit. This will provide one fitting with a shut
off to the kitchen faucet and a shut off to the filtration system. The
replacement of the angle stop is a better plumbing connection and any
number of fittings can be used for the correct application under any
circumstances.

Examples of common connections and fittings available:

• OPTIONS:
1/2” IPS x 3/8” compression x 1/4” compression
3-way angle stop

• OPTIONS:
1/2” compression x 3/8” compression x 1/4” compression
3-way angle stop

Note:
Be sure one outlet is 1/4” compression

Proper installation is dependent on your specific application and the concept of proper installation is universal.

Locate the supply , shut off your main water supply , install the proper connections

and follow the remaining instructions in this manual.

***EWS, Inc. can not anticipate all the different locations, applications and materials used by your builder and/
or plumbing contractor regarding your household or sink piping, therefore we offer a generic and common fitting
with proper instructions. A qualified plumber , plumbing supply location, or hardware store will have no problem
with alternative parts and advice necessary to install your unit.

System St art-Up and Operation Procedures

Reverse Osmosis Systems have specific issues with air in system, proper pressure in tank,

the proper draining of reject water, and proper connection between various components.

Follow these procedures for new installations and all filter/membrane replacements.

A proper start-up insures the system is without issues.

If anything is discovered, this is the time to discover it and correct any problems or

questions that arise. Lack of a proper start-up will void the warranty.

Only For Units with Electrical Connection: Units with UV Option and/or Booster Pump Option
Step 1A: Connect UV lamp cord and plug in transformer unit to typical 110v electric outlet.
Step 1B: Connect Booster Pump cords and plug in transformer unit to typical 110v electric outlet.

NOTE: Electrical outlet must be dedicated and unswitched. Be aware of any GFI outlets and

the need to reset. Surge supression highly recommended.

For All Units:
Step 2: Close inlet water supply to thesystem.

Turn off water supply to other devices that may be connected to this unit.

Step 3: Close storage tank valve. Storage tank valve should be closed. Tank valve handle is

perpendicular or at a 90º angle to the yellow tubing connected into the tank valve.

Step 4: Pull up and lock dispenser/faucet handle in open position (if using another type of

dispenser - put into open position).

Step 5: Turn on any main water supply which was shut off earlier (usually for new install).

Open inlet water supply to the system.

NOTE: Initially you may observe a sputtering. It may take up to 10-15 minutes for water to begin

to drip from dispenser/faucet.

Step 6: Once a steady drip is available (drips about a gallon of water per 1-11/2 hours),

Close the dispenser/faucet

Step 7: Open storage tank valve, so that tank valve handle is parallel or inline with the yellow

tubing connected into the tank valve.

Step 8: Allow system to fill the tank twice and drain both tanks of water produced before

actual use**. This will wash carbon fines, membrane preservatives, and air*** from the
system. This process may take in excess of 10 hours.

NOTE: This correct procedure of “fill then empty, fill then empty, and final fill” may be a full day

or an overnight procedure. This is the proper way this type of system is started up.

Continue with the proper start-up of the reverse osmosis system

EWS, Inc. / Environmental Water Systems

System Start-Up and Operation Procedures - Continued

Continue with the proper start-up of the reverse osmosis system

Step 9: Allow system to fill (this may take up 7 hours) and use as normal. If applicable, only

open water supply to other devices connected to this unit after storage tank is filled.

Step 10: Inspect for leaks at all connections, fittings and/or housings. If a problem exists,

please shut off water supply to the system and consider the following solutions;

• Plumbing connections at the inlet/supply connection, saddle tapping valve, or angle stop.
Please review all plumbing procedures and correct.

• Plumbing connections to dispenser/faucet and any other fixtures or cross-connections.
Please review and correct.

• Inspect for leaks at all unit connections such as connections between housings, the
membrane &/or cartridge housings. Report any issues for assistence or needed part(s).

• Inspect for leaks at all tubing connections and the labeled “Feed” and “Faucet” connections
between the supplied tubing and the quick connect fittings. To insure proper connection,
give a light “tug” (not a hard pull) on tubing to check the grip on all fittings.

**CAUTION: Do not drink water from system until start-up procedures have been completed and system has

been flushed properly. Improper start-up may result in poor performance of the system. Proper
procedure will rinse and purge system. Do not make water available to any ice-makers,
rerigerators or any other devices until the system is completely flushed.

***WARNING: UPON INST ALLATION OR FIL TER/MEMBRANE REPLACEMENT AN R.O. SYSTEM MA Y HA VE T O

BE “BURPED” OF ANY AIR IN THE LINES.

YOU MA Y HA VE T O FOLLOW THIS PROCEDURE TO FINALIZE THE INST ALLATION:

CLOSE THE TANK VALVE (See page 4.2-11), CLOSE (if applicable) WATER SUPPLY TO OTHER DEVICES
CONNECTED TO THIS UNIT, OPEN AND LOCK DISPENSER (observe sputtering from dispenser or a slow drip),
THEN ROT ATE THE UNIT 90 DEGREES CLOCKWISE AND HOLD IN VERTICAL POSITION, AFTER A MINUTE
RETURN UNIT BACK TO HORIZINTAL POSITION, THEN ROT A TE THE UNIT 90 DEGREES COUNTERCLOCK­WISE AND HOLD IN THAT VERTICAL POSITION. AFTER 1 MINUTE, RETURN UNIT BACK TO HORIZONTAL
POSITION. WATER SHOULD DRIP AT A STEADY FLOW (about 1-11/2 gallons per hour) WITHOUT SPUTTER­ING OR ANY GURGING SOUND. REPEA T AS NEEDED. THEN CLOSE DISPENSER, OPEN T ANK V AL VE, OPEN
(if applicable) WATER SUPPLY TO OTHER DEVICES.

NOTE: Cloudy Water - If you draw your water into a glass and it appears to be cloudy, it’s only air and

nothing bad. Let the glass sit and watch the air rise and dissipate. The filter cartridges used
are full bed depth. The carbon (GAC) cartridges have a great deal of surface area. It may take
24-48 hours for this to correct itself after you have filled and emptied the tank 2 times.

If any damage was identified in shipping or handling. You’ll need to make a claim with the shipper, as indicated on our
Packing Materials, our Packing Slip and the published General Terms and Standard Conditions of Sale.
If you have identified a problem, please contact our offices. The Best Way; go to www.ewswater.com, click button “Contact
Us” and click link to “Customer Service and Help”, fill out the form and help will be on the way. Let us know if we can offer
advice on a plumbing issue that may not be related to the actual unit, or a question or issue that may be unit related. If in
need of a part under warranty we can readily send it. Parts (original only) needed out of warranty can be obtained through
your contractor, local distribution or at www.waterontheweb.com.

WARNING: Maximum pressure is 65 PSI. Pressure unregulated can surge or exceed the maximum rating on this and
many items in the home. High pressure creates a water hammer or banging pipes. It’s also the reason to use stainless
hoses for washer machine connections and not the rubber. A pressure reducing valve (PRV) at your main water service line
(if not code) is greatly recommended by many manufacturers’ of many different household items, plumbing products and
appliances and must be checked annually. A point of use (sink location) pressure limiting valve is also available.

R.O. - Cleaning of Empty Housings

NOTE:

All containers, surfaces and items exposed to water can accumulate a clear or discolored film which may also be

slippery or slimey to the touch. This is a bio-film that is non-pathenogenic and usually of no harm.

This film is most commonly a nuisance and is readily wiped off. It is this reason we suggest a simple

cleaning procedure prior to returning new filters and membranes to the reverse osmosis system.

This procedure may be performed at any time when changing filters and membranes,

or after extended periods of inactivity of the system.

Step 1:
A: Empty All Available Filter Housings** by Following S teps 1 through 4: R.O. - Replacement of Filter Cartridges.

(Open faucet, Close inlet water supply , Empty all housings of their filters)

B: Empty Membrane Housing by Following S teps 3 and 4: R.O. - Replacement of Membranes.

(Step s 1 and 2 have been already done, see above “A”, Empty housing of the membrane)

**NOTE: All 4 and 5-S tage Units have In-Line PostFilters. These self-contained filters are not included in this procedure.
Step 2: Using disinfecting wipes, mild cleaning solution, and/or warm water and soap - simply wipe around the

housings and any exposed areas. Remove any film and/or discoloration. Repeat, if needed. Rinse thoroughly .

Step 3: Follow all procedures for the replacement of the filters and the membrane.

CHECK AND FOLLOW ALL APPROPRIA TE STEPS FOR “SYSTEM ST ART -UP AND OPERATION PROCEDURES”

RSR-100 and RSR-150 Control Valves

Installed on every R.O. Unit produced by EWS, Inc. This one control valve takes the place of up to 3 devices commonly

1) The control valve monitors the water entering the storage tank and when the storage
tank is full, the valve turns off the water processing of the system. Less Waste.

2) The control valve regulates the correct amount of reject water flushed to the membrane.

3) The control valve has a positive sealing check valve. The check valve accurately monitors
internal pressure and protects the system from pressure surges and reverse flows which
could damage the membrane.

Note: It is important to completely empty the storage tank monthly to provide a complete tank of fresh water to

prevent TDS “creep” which prevents the proper pressure on this control valve and within storage tank.

CT A Membranes

3-Stage Unit s only

needed in a reverse osmosis system and can be easily replaced if needed.

TFC Membranes

4- & 5-St age Units

Correct Application of Booster Pumps (Five-Stage Units Only)

The pump is replaceable as needed and is always installed after the first stage (“Sediment”) and provides the proper

and required and constant pressure (minimum 40 PSI) through the membrane.

Booster pumps are critical to the effective performance of reverse osmosis membranes and
are recommended in applications where feedwater pressure is less than 40 PSI.Feedwater
high in Total Dissolved Solids (TDS) may need a boost, in order to perform within rejection
parameters.

Standard Components: Always connect in the following order:

1) Transformer 2) TSO-Tank Shut-Off Switch 3) Pump

T ank Shut-Of f Switch: Mounted in-line with the hydro-pnuematic pump as close to the tank
as possible, this switch will automatically turn the booster pump off when the tank is full.

Maintenance Guide - Reverse Osmosis Systems

INITIAL INST ALLA TION

Follow the proper procedures for the set-up, installation and start-up of all systems. Problems (short and long-term) occur
when the systems are installed incorrectly . If any questions arise after installation, consult the trouble shooting guide for
assistance.
NOTE; ONCE INST ALLED CORRECTLY, THE MORE CONSISTENTL Y THIS PRODUCT IS USED THE BETTER.

REPLACEMENT OF FIL TERS, MEMBRANES, AND UV LAMPS (if applicable)

Follow the proper procedures for the shut-down of system, and the removal and replacement of the filters, membranes and/
or uv lamp (if applicable). Once a replacement procedure has been completed, the proper start-up of all systems is again
as important as it was when the system was first installed. If any questions arise after replacement procdures, consult the
trouble shooting guide for assistance.

Note: If the system was fine and only started having issues after the replacement of filters, membrane, and/or uv lamp,
than some procedure was not properly followed when re-starting the system.

MAINTENANCE

Reverse osmosis systems can be a sensitive product not applicable to other drinking water filtration systems because of
these various issues;

• Interconnection of system to a storage tank to store production water

• Interconnection of system to a drain line for draining rejection water

• Need for proper line pressure over the membrane for proper water quality and overall function

• Limits to the quantity of available water due to production rates over a day (divide by 24 provides

the RO production capacity over an hour) If you empty a tank it can take hours to refill before usage

• Interconnection to other devices, length of tubing for filtered water to travel and the potential for
warranty issues with other items due to the aggressive nature of RO water

MONTHL Y
 Empty S torage Tank
This is a little trick you won’t get from someone trying to sell you a service/maintenance agreement.
Empty water from and close any other devices connected to RO unit. Open and lock your dispenser in place in order to
empty storage tank completely of water . If you have a dispenser that does not lock open than hold open until tank has
been emptied. Wait until you see the water come to a very slow trickle or drip. Close dispenser and allow RO to manufac­ture a completely new and fresh tank of water. Do this overnight to allow RO to produce enough water before you rise the
following day . Once tank is refilled than open other devices connected to RO. This procedure keeps the proper pressure on
the tank bladder and on the RSR control valve and allows better water flow , quality and quantity .
 Check System
Visually check dispenser connections, system connections and drain. Be aware of any excessive household water
pressure or changes in your incoming water quality as well as changes in the production water.

YEARLY
 Replacement of filters, filter cartridges, in-line filter cartridges, and uv lamp (if applicable).
Note: Replace, as needed, due to local water conditions and usage but do not exceed one year.
 Membrane can be replaced as a convenience with all other filters on an annual basis (Purchased as a set for your
specific RO system). However, membrane may last between 18 months up to 3 years, based on local water conditions
and usage.

STORAGE OF UNIT OR PROLONGED PERIODS OF INACTIVITY, if applicable
 Empty tank completely , shut off water supply to unit, remove filters and membrane and store in a cool dry location or
refrigerator.
 Upon return, begin a disinfection procedure prior to any filter/membrane replacement, replace filters and membrane,
and begin start-up procedure as if it were a new unit.

Problems

with Start-Up &/or

Filter Replacements

No water after installing the
system

EWS, Inc. / Environmental Water Systems

Possible Causes Solution

Improper start-up of the unit upon
installation or filter replacement

Start with the start-up procedures and follow them as
if the unit was just installed

4.2-27

No water after replacing
filters, in-line filters, &/or
membranes

It takes hours after a proper install
to have a full tank for use

The interconnection between the in­let, outlet, drain and tank lines can
cause air in the unit at the RSR con­trol valve. Air in lines, and at this
valve, will not allow R.O. to function
properly.

Tank valve is closed

Tank pressure is off,
Tank pressure too low or too high

Make sure start-up was performed correctly and wait
for tank to fill. Follow instructions for proper start-up

Air in Lines “Burping Procedure”
Close the tank valve,
Close (if applicable) water supply to other devices that
may be connected to this unit,
Open and lock dispenser (observe sputtering from dis­penser or a slow drip).

Rotate the entire unit 90° degrees clockwise and hold in
vertical position, after a minute return unit back to hori­zontal position ,
Then rotate the entire unit 90° degrees counterclock­wise and hold in that vertical position, after one minute
return unit back to horizontal position,
Water should drip at a steady flow (about 1-11/2 gallons
per hour) without sputtering or any gurgling sound.
REPEAT AS NEEDED.
Then close the dispenser, open tank valve, only open (if
applicable) water supply to other connected devices once
andonly once the tank has filled completely.

Open valve, in line or parallel with yellow tubing, close
other devices and begin proper start-up procedure.

The tank air pressure should be 5-7 psi without water in
tank for proper operation. Pressure variances due to
higher elevations may occur. Under or over-inflation will
prevent proper operation of system. Check with accu­rate (0-20) gauge Empty tank and adjust (if needed) us­ing a bicycle or sports ball pump. Begin proper start-up
procedure

EWS, Inc. / Environmental Water Systems

Limited Warranty

Notification:

This warranty is referenced by EWS, Inc. in all literature, addressed in General T erms and S tandard Conditions of Sale,
and is published in its entirety in all EWS, Inc. product manuals, websites, and in all service guides supplied with all
product.

Limited Warranty:

EWS, Inc., a Nevada corporation, hereby warrants all products to the original consumer purchaser to be free from
defects in material and workmanship as stated in the following paragraphs:

• All residential point of use: countertop filtration, in-line filtration, undercounter drinking water filtration, shower filtration,

residential reverse osmosis, and point of entry pre-sediment units or systems for one year from date of purchase.

• All residential point of entry: pH decreasing and softener (resin and ion-exchange) systems, Environmental (EWS)

Water Systems, pyrolox units, CWL whole-home (filtration media) systems, pH increasing reagent (sacrificial media)
units for 10 years on the tank and riser , 10 years on the ICN conditioner(s) (if applicable) and 3 years on the valve head
from date of purchase.

• All commercial systems: Dependent on specification and application, please consult with EWS, Inc. upon specifica-

tion.

• All filtration medias, resins, cartridges, uv lamps, and/or membranes are not covered by any warranty. Filter media,

resin, cartridge, uv lamp, and/or membrane replacement or maintenance schedule will vary and must be replaced, as
necessary , as determined by usage and local water conditions.

Product performance may vary based on local water conditions, proper product specification and application, proper
plumbing application, setup, installation, startup, maintenance and/or usage. To ensure proper operation, follow all
setup, installation, start-up and maintenance procedures as detailed in all service guides.

Not intended for use where water is microbiologically unsafe or with water of unknown quality without adequate disinfec­tion before or after unit(s). The contaminants or other substances removed or reduced by these and any other water
filtration or treatment devices are not necessarily in your water. T o confirm the presence of any primary and secondary
contaminants, have your water supply completely analyzed by an independent and approved facility or if applicable,
contact your local water utility for information. Aesthetic, non-health related, or constituent s without set federal st an­dards may be part of water testing but are insufficient to determine proper application of any water filtration or treatment
device.

EWS, Inc. will replace, free of charge, during the warranty period, any part which proves defective in material and/or
workmanship under proper product and plumbing specification and application, normal and proper installation, use,
service and proper care as published in detail in all service guides included with product. Labor charges are excluded
from any warranty service or repair and are not the responsibility of EWS, Inc. Shipping charges may apply to delivered
replacement parts or materials. Charges may also apply for the cost of any replacement media, resin, cartridges, uv
lamp and/or membrane from any warranty service or repair. Information can be obt ained at any time through a local
dealer, distributor , representative or direct from EWS, Inc. and/or on-line at; www .ewswater.com or www .ewswater .com/
techandspec.html. Replacement parts can be obtained from your local dealer , distributor or contractor .

This warranty is the exclusive warranty granted by EWS, Inc. and is in lieu of all other warranties of merchantability and
fitness for a particular purpose and is further limited to defective parts replacement only . Labor charges and/or damage
incurred in setup, installation, and startup, or repair , or replacement, as well as, incidental and consequential damages
connected there with, are excluded, and are not the responsibility of, and will not be paid by EWS, Inc.

This warranty is void for any damages due to improper product and/or plumbing specification and/or application, misuse,
abuse, neglect, accident, acts of nature, action of any military or civil authorities, improper handling and transportation,
or improper setup, installation, and/or startup, or any violation of instructions furnished by EWS, Inc., or any replace­ment parts other than genuine parts or replacements supplied by EWS, Inc.

This warranty is not a warranty of merchantability , fitness, taste, aesthetics, and/or performance that may be subject to
improper product and/or plumbing specification and/or application, misuse, abuse, neglect, accident, acts of nature,
action of any military or civil authorities, improper handling and transportation, or improper setup, installation, and/or
startup, or any violation of instructions furnished by EWS, Inc.

This warranty is not a warranty of merchantability , fitness, taste, aesthetics, and/or performance that may be personal

Limited Warranty - Original Purchaser ’s Responsibility

Keep a record of the purchase receipt and/or installation receipt. Purchaser is required fill out warranty registration form(s)
on applicable product(s) and register all product by either on-line @ www.ewswater .com, telephone, postal delivery , fax, e­mail (either [email protected] or information provided to customerservice@ewswater .com). Failure to do so voids
the warranty . EWS, Inc. does not sell, show or make available any information on any consumer in our database. This
database is to ensure, if needed, proper warranty service, and good customer service for years to come. Please see our
privacy policy published in our website at www.ewswater .com.

Know Y our W ater:

• If on a municipal system, large or small, it is your right as a consumer to have access to the most recent test results and

to expect adherence to federal guidelines, as well as any state or local requirements. Any problems should be reported to
the appropriate agencies. Please acquire those municipal test results to become an informed consumer .

• If on an individual well, have your water completely and independently tested. Local code may require a simple test for

coliform bacteria to approve a well, however you may be unaware of potential problems for you and/or your home. A local
water salesman is looking to close a sale and is going to test for hardness minerals and a few simple and obvious issues,
which may or may not be contamination problems. Their solution is almost always the same and yet may provide no
resolution to any true problems. Obtain our “Guide for the Private Well Owner” on our website; www .ewswater .com (under
Service Guides). Review our section on well water testing and applications in our complete catalog with your local
distributor , dealer, or our representative or visit our website.

• WARNING:

Some restrictions apply to the use of softeners. Contact your local municipal water district or Gov't Agency. Brine
discharge is already restricted on, or may be a problem for, septic applications and waste water treatment facilities. Since
some states have already restricted softeners to metered valves to prevent excessive brine discharge, EWS, Inc. only
provides metered valving in its line of softeners.
Restrictions may also apply to hot-side only , salt-exchange tanks or services, or an outright ban. Local water dealers and
other organizations do not inform consumers of these issues and believe these rules are unenforcable. The consumer is
ultimately responsible.
Softeners may also provide warranty issues with pools and spas, certain other products and finishes. Softened water
should not be used for drinking, cooking, pets or plants and is usually bypassed or “looped away” from the cold side of the
kitchen sink. Reverse osmosis, which also has its drawbacks and issues with other products and materials, may be used
to remove the salt from the water that the softener put in at the kitchen sink, yet may be misapplied for the actual local
water conditions.

Any problems of water quality , or the fitness of any EWS, Inc. product that is associated with any mechanical, construc­tion, application, installation, and/or environmental issue(s) (ie: flow rates, line pressure, piping materials, broken supply
lines, changing water conditions; well or municipal water quality , et. al.), known or unknown, of the home or facility will not
be considered by EWS, Inc. until such issue(s) have been resolved.

Responsibility for the proper product and/or plumbing specification, application and/or installation of any device manufac­tured by EWS, Inc. lies with the consumer, their builder contractor, plumbing sub-contractor and any other installer of
choice. Items do not specify and/or install themselves. EWS, Inc. has provided many sources to acquire information on
the proper application of systems and their installation prior to any purchase. EWS, Inc. manufactures a complete product
line of point of use water filtration systems and point of entry filtration, softening and/or conditioning systems and/or
appliances. EWS, Inc. and the distributors of EWS, Inc. will stand behind the warranties of materials and workmanship.
However, EWS, Inc. and the distributors of EWS, Inc. and the Environment al Water Systems Product Line do not bear any
responsibility for improper applications of product and/or improper installation. It is for this reason that EWS, Inc. provides
complete information on all product for your understanding, specification, application and selection, and proper plumbing
application and installation.

T o obtain warranty service support, cont act your local dealer or contractor from whom you obtained the product or contact
EWS, Inc., Customer Service, via phone, fax, or email.

A Quick Reference of Systems and Combinations for Various Applications

EWS - The Leader in Whole Home Water Filtration

EWS Series - The Environmental Water System

Whole Home Water Filtration and Physical Conditioning

Filters all the water to the whole home and offers the consumer an alternative to harsh salt softening. EWS
conditioning causes a physical change in how naturally found calcium and magnesium minerals react in the
water and on surfaces. EWS keeps these minerals in the water for a pure, fresh taste while helping solve
those problems associated with hard water. The result: less spotting, easier clean up, and prevents scale
build-up in pipes and water heaters without the damaging effects of salts. No slippery feeling. No brine
discharge. The best combination of whole home filtration and the alternative to salts and softening. Required
or chosen upgrade options: Sink units for specific removal needs or concerns.

CWL Series - Whole Home Water Filtration Appliance

Great for filtration to the whole home of chlorinated water supplies, for drinking, cooking, showering, and bathing (great for
hair and skin) - all uses. Also used for non-chlorinated applications to safeguard water from VOC’s due to ground water
contamination. Use EWS Series to filter and physically condition water, if water hardness is an issue. Required or chosen
upgrade options: Point of use, drinking water system, or reverse osmosis for limited sink applications based on water
conditions or additional water concerns for drinking use.

EWS - The Complete Choice for Sink Filtration

Drinking Water Filtration Systems

Sink filtration product for oral intake, drinking, cooking, ice-making, etc., to protect consumer against known or
unknown water issues or concerns. FUGAC250 (“better”) for carbon block filtration of chlorine and VOC’s, lead,
and cysts. UU250 (“best”) for the additional safeguard from bacterial, viral, e-coli and microorganisms. No storage
tanks, no limited supply, and no wasted water associated with reverse osmosis systems.

Reverse Osmosis Systems

Sink filtration product for oral intake, drinking, cooking, ice-making, etc., to protect consumer against known or
unknown water issues or concerns. RU300 series for chlorinated municipal water. RU400 series for potable non­chlorinated, well or municipal supplies. RU500 series optional for harsh well water. Add UV module for the addi­tional safeguard from bacterial, viral, e-coli and microorganisms. Be aware that RO has specific issues and
drawbacks (ie: wasted water, limited production, storage tank space, very aggressive water), and has specific
applications, making these systems widely misapplied. Select the product that’s right for you.

EWS - The Resource for Well Water Solutions

High Oxidation, Purity Media Systems

For the removal of iron, manganese and hydrogen sulfide. Installed at the point of entry, this is a removal of these problems, not
the trade-offs of ion-exchange. Automatic backwash with no brine discharge, no chemicals to add, and years between any
maintenance (media replacement) make these systems a must with wells having these pre-treatment issues.

Plus: pH Increasing Reagent or pH Decreasing Resin Systems, Pre-Sediment Filtration .......

Softeners

If water hardness is an issue, water softeners will soften the water through ion-exchange. This process substitutes
naturally found calcium and magnesium (hardness) minerals for sodium or potassium chloride (salts) and
filter the water. Water will spot less, wipe off easier, and prevent lime scale in pipes and water heaters. However,
restrictions on softeners due to brine discharge into your septic tank, salts, and wasted water are growing. Softeners
may also void warranties on other household products (ie: pools, spas, special finishes, etc.) Once softened, many
people do not like the slippery feeling of the water and reverse osmosis becomes necessary to remove the salt from
drinking water that the softener put in. If a softener is chosen, application on the hot side only is recommended. Ironically ,
we make some of the most efficient metered softeners in the industry. Consider on hardness above 20 grains and use
on excessive hardness above 30 grains. Use EWS Series as an alternative to filter and physically condition water below
30 grains.

Let us @ EWS, Inc. help you specify the correct product(s) for your application.

Know and understand your “city” water or have well water tested completely to specify the correct point of entry

system(s). Choose a filtration upgrade, at the sink, for consumption based on tested results, and/or additional needs or

concerns. A complete solution may use one or more products to satisfy an application.
