SOFTENER DISCLAIMER:

Softeners do not filter. They simply exchange natu­rally-found calcium and magnesium (hardness) miner­als for either sodium or potassium chloride. Please note
drinking softened water must be avoided, in addition,
there can be warranty issues with certain product and
finishes, and bans or restrictions due to the environ­mental impact of the brine discharge. If the “slippery” or
“silky” feeling and the perceived benefits are preferred,
install to the inlet to the water heater(s) for use on hot
water only.

WA TER FILTRA TION T O THE WHOLE HOME:

Most homes on “city” water simply require the correct
Whole Home Water Filtration Appliance installed on
the homes’ main service line.

Complete installation of any EWS or CWL Whole Home
Unit can be as easy for a professional contractor as
the installation of a water heater.

Specify by size of main water service line after homes’
shut-off valve. Options for smaller or larger homes,
usage and/or other conditions. The correct application
eliminates the need and expense of a “soft water loop”
which would bypass salt-softened water to any drink­ing water or hose bibs

IF YOU ONLY READ ONE PAGE IN THIS MANUAL - THIS IS IT !!!

INSTALLATION SUMMARY - 12 STEPS

Step 1:

Locate the following: **Main Water Supply Line, Drain Access, Electrical Outlet and Clearances.

Caution: **Avoid soft water loops that bypass cold side kitchen sink(s) from these applications.
Step 2:

Check the incoming Water Pressure. Maximum water pressure not to exceed 65 psi.
Install a pressure regulator (PRV) if the water pressure exceeds or can surge above 65 psi.

Step 3:

Place the tank at the point of installation, making sure the tank is level (tanks have self-leveling bases) and
on a solid floor, note sp ace necessary to complete the inst allation. Inside or Out side? See details.

Step 4:
Caution: Since handling and moving the unit may loosen the valve head - make sure to Check and Hand

Tighten V alve Head on the Tank. Hand Tighten the Valve Head in a Clockwise Direction. Make sure tank
cover or plastic dome, if applicable does not interfere or cut into the connection.

Step 5:

Identify Water Main Supply and plumb inlet (supply) and outlet (filtered) into the unit following the directional
arrows molded onto the valve body. Plumb the unit with the bypass and the male yoke included, or for larger
brass valved units, a bypass must be plumbed. Do not cross-connect or plumb backwards. See detailed
installation schematics and the helpful information in this manual.

Step 6:

Connect a backwash drain line (minimum 1/2” or 3/4” ) based on application and provide an air gap.

Step 7:

Partially Open Inlet V alve Only.
Keep outlet valve closed. (Larger brass valved units, keep plumbed bypass valve closed).

Step 8:

Plug the unit into an electrical outlet. Be sure the outlet is dedicated and unswitched.
An outlet that cannot be turned “on” or “off.”

Step 9:

Set the time of day on the valve display . The valve will read or flash between the time of day and the
remaining days before the next automatic backwash.

Step 10:

Backwash and Flush the system properly and completetly until the drain water runs clear.

Step 11:

Open Outlet V alve slowly (Larger valved units, keep plumbed byp ass valve closed).
Check all plumbing connections

Step 12:

Run hot/cold water throughout the home (at every tap) to flush pipes and water heaters to prepare unit for
usage. You are done.

Fill Tank Slowly. Once t ank is filled, completely open inlet valve.

A typical installation no more difficult then a water heater. Just simply follow the proper set-up, installation

and start-up and if you have any questions call our offices and we would be glad to help in any way.

For additional details regarding line pressure, outside installations or other topics,

please review the troublshooting section at the back of this service guide

GENERAL INFORMATION AND PRE-INSTALLATION CHECKLIST

Verify: All components are included with the unit and were not damaged in shipping.
Caution: Do not attempt to install any system using defective or damaged components. Do not install any

system that has been misapplied.

Warning: When plumbing, use protective eyewear to prevent possible eye injury due to flying objects.

When using an open flame and/or hot materials, take the necessary precautions for you and the
environment to prevent burns, burning and/or fires.

 Water Pressure and Flow Rate:
A minimum of 35 PSI (40 PSI for Iron units) and 8 GPM for 1035 & 1054 units/12 GPM for 1354 units is
required for backwash valve to operate effectively. Water pressure not to exceed or to surge in excess of a
maximum of 65 PSI for the system. Unsure of pressure or it’s ability to surge? A pressure reducing valve
(PRV) becomes an insurance policy and is recommended for this and many other products that limit high
pressure in your home.



Water Temperature Range:



Feed water temperature not to exceed 95°F or be allowed to go below 40°F . Protect unit from exceeding high
temperatures and never allow unit, its’ drain line and any water to freeze. Must avoid any thermal expansion
from water heaters



Electrical:



An uninterrupted alternating current (A/C) supply is required. Please make sure your voltage supply is com­patible with your unit before installation.



Existing Plumbing:



Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up heavily and
clogged with lime and/or iron should be replaced. Problem with iron? Our separate iron filter unit should be
installed ahead of any other unit. Old galvinized or combinations of plumbing materials can cause water
issues and conditions. Pre-existing conditions may affect initial effectiveness of any product.



Location of Tank, Drain and Electrical:



Units can be installed, almost anywhere. Inside or outside. However, use your common sense. Valves are
water resistant, not water proof. Protect any system from the elements. Review issues on water flow rates
and pressure, and environmental and water temperature ranges. The tank should have access to the supply
water, provide filtered water to the home, be located close to a clean working drain, have an electrical outlet
available, and be connected according to all local plumbing codes.



By-Pass Valves:



Larger brass valved units and all Iron Units are required to be plumbed with an bypass and unions (see
installation schematics). Some units (CWL/EWS-1035 LTD, CWL/EWS-1054, CWL/EWS-1354) come com­plete with a dual-port bypass and male yoke that is required to use for a simple installation.



Drain Connection:



Nominal drain line and drain size on 1035/1054/1354 (non-iron) units should be a minimum of 1/2”. Larger
1 1/2” brass valves require 3/4” drain line. Any drain line exceeding 20’ in length and/or expected to flow over 5’
above the height of the drain port requires an increase in drain line size by an additional 1/4” to either 3/4” or
1”. Install, non-restrictive, check valve in drain line, if drain water is expected to flow over 5’ above the height
of the drain port. Never restrict the backwash drain water flow.Teflon tape is the only sealant to be used on the
drain fitting.

All plumbing should be done in accordance with all local plumbing codes.

All the information that you may need is in this product manual and available on the web.

Identify the unit you are installing and follow the detailed, Set-Up, Installation and S tart-Up of that unit.

WARNING: IMPROPER INSTALLATION WILL RESULT IN THE VOIDING OF ANY WARRANTY.

EWS & CWL 1035, 1054, 1354

1 - PREPARE FOR INST ALLA TION:

Check the Following:

Main Water Supply Line, Drain Access, Electrical Outlet, and Clearances to comlepte the inst all.
Location of T ank: Units can be installed, almost anywhere. Inside or outside. However , use your common sense. V alves

may be water resistant, not water proof. Protect any system from the elements. Review issues on water flow rates and
pressure, and environmental and water temperature ranges. The tank should have access to the supply water, provide
filtered water to the home, be located close to a clean working drain, have an electrical outlet available, and be connected
according to all local plumbing codes.

Water Temperature Range: Feed water temperature not to exceed 110°F or be allowed to go below 40°F. Protect unit
from exceeding high temperatures and direct sunlight, and never allow unit, the drain line and any water to freeze.

Electrical: An uninterrupted alternating current (A/C) supply is required. The system is ideally located within 4-6 feet of a
1 10 volt outlet to allow the unit to be plugged in. A 24 volt motor and transformer is available for longer electrical runs (use
10-2 regular lamp gauge wire). The 24 volt transformer must be located inside.

Existing Plumbing: Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up heavily
and clogged with lime and/or iron should be replaced. Problem with iron? Our separate iron filter unit should be installed
ahead of any other unit. Old galvinized or combinations of plumbing materials can cause water issues and conditions.

Drain Connection: Nominal drain line and drain size on 1035/1054/1354 (non-iron) units should be a minimum of 1/2”.
Any drain line exceeding 20’ in length and/or expected to flow over 5’ above the height of the drain port requires an increase
in drain line to 3/4”. Install, non-restrictive, check valve in drain line, if drain water is expected to flow over 5’ above the height
of the drain port. Never restrict the backwash drain water flow.Teflon tape is the only sealant to be used on the drain fitting.

Check Incoming Water Pressure and Flow Rates: A minimum of 35 PSI and 8 GPM for 1035 & 1054 unit s/12 GPM
for 1354 units is required for backwash valve to operate effectively . W ater pressure not to exceed or to surge in excess of
a maximum of 65 PSI for the system. Unsure of pressure or it’s ability to surge? A pressure reducing valve (PRV), or limiting
pressure to 65 PSI is recommended for this and many other kitchen and bath products in your home. Automatic valve is
rated for 100 PSI and the tank is rated for 150 PSI, however the overall system with various connections has limitations to
excessive pressure. Water pressure measuring 65 PSI during the day may surge to over 100 PSI at night when the
automatic backwash occurs.

Install (often required by code) a pressure regulator (PRV) if the water pressure exceeds or can surge above 65 PSI.

2 - UNBOX UNIT : CHECK T ANK AND V AL VE AND LOCATE BYP ASS AND MALE YOKE:

1) PLACE THE T ANK WHERE YOU W ANT TO INST ALL THE UNIT.

Make sure the tank is level and on a firm base. Black bases on tanks are glued-on and self-leveling. If necessary , lift t ank
and tap the part of the base to floor , in order to level unit. T ake note of the clearances necessary to complete the inst allation.

2) CHECK AND TIGHTEN V AL VE HEAD ON THE T ANK.

Hand Tighten the V alve Head in a Clockwise Direction. Make sure the stainless tank cover or plastic dome (1354 unit s) does
not interfere or cut into the connections.
WARNING: S tainless covers are non-functional, if “dinged” in handling, turn to good side.

3) CONNECT BYP ASS VAL VE AND MALE YOKE TO V A LVE HEAD.

Make sure bypass valves are facing up. Keep bypass valve level (horizontal). Do not put, up or downward, and/or sideways
pressure on bypass valve, this will not allow nipples and o-rings to seat squarely and completely and over time could cause
under pressure connection failure.

3 - PLUMBING LINE CONNECTIONS:

1) IDENTIFY THE MAIN W A TER SUPPL Y .

Do Not Assume. You may have to perform “the old bucket test” to determine where the water is coming from.
Make sure the whole facility is on the line. Some cold water lines (kitchen, island, wet bar sinks, refrigerators, ice

makers) may have been plumbed separately , if previously plumbed for (salt) softened water . Y ou may have to recapture
those lines by replumbing that manifold. Or, capture the main water supply before the byp assed or “looped” away lines,
usually found at, or after , the main water shut off. However , some plumbing designs prevent this ideal installation. A sink
(point of use) filtration unit can be used for that missed location.

EWS & CWL 1035, 1054, 1354

4.2-11

3 - PLUMBING LINE CONNECTIONS - Continued:

Hose bibs are unnecessary to capture unless required by consumer. Irrigation (which should tee-of f prior to the home’s
main water supply) uses a lot of water and this connection should be discouraged. It puts an unnecessary burden on the
unit and the media.

2) USING THE CONNECTED BYP ASS VAL VE AND 1” MALE NPT YOKE.

3) PLUMB INLET (supply) AND OUTLET (filtered) INTO THE UNIT.

Follow the directional arrows molded onto the valve body and bypass. See pictures below for; top/front/back and left/
right views to prevent plumbing the unit backwards. Teflon tape is the only sealant to used on any of our fittings.
NO Heat, No Torch; Leave at least 12” between the male yoke and any solder joints. Failure to do this could cause
interior damage. Consider flexible stainless (1”FNPT x 1”FNPT (3/4” if your application) and at least 18” in length) con­nected to copper male adapters, or some other applicable connection - no heat, saves time, neat install, if applicable
code to your application.

4) WARNING: ONCE PLUMBED, DO NOT TURN ON W ATER, UNTIL YOU BEGIN START -UP PROCEDURES.

4 - DRAIN CONNECTIONS:

1) LOCA TE DRAIN PORT ON THE LEFT (OUTLET) SIDE OF THE V AL VE HEAD.

Inserted into valve drain port is a flow control housing (male o-ringed insert x 1/2” FNPT) which is locked in by the retainer clip
The flow control housing has a flow washer which determines the restricted flow rate (4 gpm - 1035 and 1054, 7 gpm - 1354).

2) DO NOT OVERTIGTHEN CONNECTIONS. IMPORT ANT TO READ THE FOLLOWING:

Nominal drain line and drain size should be a minimum of 1/2”. Drain line exceeding 20’ in length and/or drain water that is
expected to flow over 5’ above the height of the drain port requires a 3/4” line and drain. Install, non-restrictive, check valve in
drain line, if drain water is expected to flow over 5’ above the height of the drain port . Never restrict the backwash drain
water flow.
A drain adapter or hose barb has been supplied and is loosely connected awaiting final installation. You may use this or
any other applicable adaptor or connector depending on your drain line.Care must be taken when screwing in any connection to
the flow control housing, not to crush piece and distort the flow washer, crucial to the ef fective backwashing of the system.

Flexible tubing, poly tubing or any hose must be clamped (do not overtighten) and do not allow any tubing to kink.
Hard piping of drain line: NO Heat, NO Torch, leave at least 12” between drain port and any solder joints - remember to

use a union (a quick disconnect feature) for future servicing applications. Therefore, the system will require no replumbing.
Teflon tape is the only sealant to be used on any drain fitting.

3) LOCA TE A SUIT ABLE PLACE TO DRAIN.

A suitable place to drain the water must be available. Usually , into a drain or trap, where the washer drains, the pool, or
any outside that has sufficient size and space for percolation. You can be flexible or creative. Do not connect the backwash line
to an air conditioning drain line. Do not freeze.

Air gap must be used, if connecting to a drain line or sewer trap, to prevent possible back siphoning into the tank.
Backwash is a mechanical way of turning over the filtration media. The discharge is only water and not a brine. The water

discharge can go anywhere, may be used, or recycled, and does not have the legal restrictions or issues of brine discharge.
