SOFTENER DISCLAIMER:
Softeners do not filter. They simply exchange natu-
rally-found calcium and magnesium (hardness) miner-
als 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 environ-
mental 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.
WATER FILTRATION TOTHE WHOLE HOME:
Most homes on “city” water simply require the correct
Whole Home Water Filtration Appliance installed on
the homes’ main service line.
Completeinstallation of any EWSor 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 drink-
ing 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 space necessary to complete the installation. Inside or Outside? See details.
Step 4:
Caution: Since handling and moving the unit may loosen the valve head - make sure to Check and Hand
Tighten Valve Head on the Tank. HandTighten 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 Valve Only. Fill Tank Slowly. Once tank is filled, completely open inlet valve.
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 Valve slowly (Larger valved units, keep plumbed bypass 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.
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

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
environmenttopreventburns,burningand/orfires.
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 com-
patible 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 com-
plete 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
11/2” brass valvesrequire3/4”drainline.Any drainlineexceeding20’in lengthand/orexpectedtoflow 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
ofthedrainport.Neverrestrictthebackwashdrainwaterflow.Teflon tapeis the only sealant to be used on the
drainfitting.
GENERAL INFORMATION AND PRE-INSTALLATION CHECKLIST
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 Start-Up of that unit.
WARNING: IMPROPER INSTALLATION WILL RESULT IN THE VOIDING OF ANY WARRANTY.

pressure to 65 PSI is recommended for this and many other kitchen and bath products in your home.Automatic valve is
ratedfor 100 PSI andthe tank israted for 150 PSI,however the overall systemwith various connections haslimitations 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(oftenrequired by code) apressureregulator (PRV) if the waterpressure exceeds or can surgeabove65 PSI.

1) IDENTIFYTHE MAIN WATER SUPPLY.
Do NotAssume. 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)mayhavebeen plumbed separately, if previously plumbed for (salt)softenedwater.Youmayhave to recapture
thoselines by replumbingthat manifold. Or,capture the mainwater supply beforethe bypassed or “looped”away lines,
usuallyfound at, orafter,the main water shut off.However, some plumbingdesigns prevent thisideal installation.Asink

3 - PLUMBING LINE CONNECTIONS:
Check the Following:
Main Water Supply Line, DrainAccess, Electrical Outlet, and Clearances to comlepte the install.
Location of Tank: Unitscanbeinstalled,almostanywhere.Inside or outside.However, use yourcommonsense.Valves
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
filteredwater to the home,be located closeto a clean workingdrain, have an electricaloutlet available, andbe 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
fromexceeding high temperatures anddirectsunlight, and never allowunit, the drain line andanywater to freeze.
Electrical: Anuninterrupted alternating current (A/C) supplyis required. The systemisideally located within 4-6feetof a
110 volt outletto allow theunit to be pluggedin.A24 volt motor andtransformer is available forlonger electrical runs(use
10-2 regularlampgauge wire). The 24 volttransformermustbe located inside.
Existing Plumbing: Conditionofexistingplumbingshouldbefreefromlimeandironbuildup.Pipingthatisbuiltup heavily
and clogged with lime and/or iron should be replaced. Problem with iron? Our separate iron filter unit should be installed
aheadof any otherunit. Old galvinizedor combinations ofplumbing materials cancause water issuesand conditions.
Drain Connection: Nominal drain line and drain sizeon1354-HF(non-iron)unitsshouldbeaminimumof1/2”. Anydrain

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 12 GPM for 1354 units is required for
backwashvalve to operate effectively. Waterpressurenottoexceed or tosurgein excess of amaximum of 65 PSIfor the
system. Unsure of pressure or it’s ability to surge? A pressure reducing valve (PRV), or limiting pressure to 65 PSI is
recommendedforthisandmanyotherkitchenandbathproductsin your home.Automatic valve is rated for 100 PSI and the
tankisratedfor150PSI,howevertheoverallsystemwithvariousconnectionshaslimitationstoexcessive pressure. Water
pressure measuring 65 PSI during the day may surge to over 100 PSI at night when the automatic backwash occurs.
Install(oftenrequired by code) apressureregulator (PRV) if the waterpressure exceeds or can surgeabove65 PSI.
1 -PREPARE FORINSTALLATION:
1) PLACE THE TANK WHERE YOU WANT TO INSTALL 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 tank
