Congratulations on your purchase of a RainSoft water treatment

system.

This Owner’s Manual is designed to assist with the operation, mainte-

nance, and installation of your water treatment system. It is our

sincere hope that this manual is clear, concise, and helpful to you as a

new owner.

Questions? If you have any questions regarding the installation, oper-

ation, or servicing of this system, please contact your local RainSoft

Dealer. Your local RainSoft Dealer is familiar with your particular

water conditions, and is able to address your concerns promptly and

efficiently.

Information on Water Treatment

Systems

There are many misconceptions that have been developed about water

treatment systems. The most common topic of confusion is the

amount of sodium (Na), not table salt (NaCl), that is added to the

water from a water conditioner. In reality, ion exchange does replace

the hardness ions in your water with sodium ions, but the common

misconception is the amount used.

For every 1 grain of hardness, the exchange process will deliver

approximately 8 milligrams of sodium per 1 liter of water. The

amount of sodium present in a standard 8 ounce glass of treated

water, that was 10 grains hard prior to treatment, would be around 19

milligrams of sodium. This is an insignificant amount of sodium

considering a typical slice of white bread has about 140 milligrams.

Another common misconception that needs mentioning is the

amount of salt used by the conditioner to regenerate the system. In the

past, water conditioners used more salt to regenerate, but that was due

to old technology and standards. Water conditioners do use salt for

regeneration, but the amount of salt varies by water consumption and

hardness levels. Fortunately, today’s technology allows us to dispense

just the right amount of salt for maximum efficiency, based on your

individual water consumption needs.

Application Limitations

• On hardness levels of 60 grains and higher, the system may not

achieve a hardness of less than 1 grain; due to high Total Dissolved

Solids, some bleed through is possible. Bleed through can also be

caused by sodium levels higher than 1000 parts per million. In either

case, your system can be programmed to minimize these effects. See

your RainSoft Dealer for details.

• Chlorine or Chloramine levels on municipality treated water should

not exceed 4 parts per million.*When Chlorine or Chloramine levels

are 4 parts per million*or greater, it can have adverse effects on your

system. In applications where high levels are a concern, pre-filtration

is necessary to reduce the Chlorine or Chloramine to an acceptable

level. See your RainSoft Dealer for details.

• When this system is installed on water with Ferrous iron, also

known as clear water iron, the maximum range of removal is based

on local water conditions. The range is generally 2 to 10 parts per

million. Your equipment may require special programming, along

with an additive to the brine tank, to maximize the equipment’s ability

to remove iron. See your RainSoft Dealer for details.

Important Note: Iron fouled resin

is not eligible for warranty

replacement.

Important Note: This system may

be installed on well water or

municipality treated water

supplies.

Important Note: Most municipality

treated water supplies contain

Chlorine as a disinfectant. Many

municipalities also inject

ammonia into the water supply,

creating Chloramine.

Maximum disinfectant level of

Chlorine or Chloramine recom-

mended from the EPA.

Helpful Tip: Another common

misconception of water treatment

systems is the idea that soft water

will produce clear ice cubes.

Cloudy or white, hazy ice cubes

are caused by air that is slowly

being released from the water

during the freezing process, which

has nothing to do with the perform-

ance of your system.

Bypass Valve

The bypass valve enables you to bypass the system in situations of: emer-

gency leaks in the equipment, service calls.

Existing Plumbing Conditions

Plumbing should be free from lime and/or iron buildup. Piping that

contains large amounts of lime and/or iron should be replaced.

Additional Specifications

• Do not install this system where water is microbiologically unsafe or of

unknown quality without adequate disinfection before or after the

system.

• This system must be installed in accordance with all applicable state

and local laws and regulations.

• The Commonwealth of Massachusetts Plumbing Code 248 CMR shall

be adhered to. A licensed plumber shall be used for this installation.

• This system must be installed in an area not affected by extreme heat,

cold or the elements. The selected installation area must be adequate

for easy service and accessibility.

• This system is designed to treat cold water only. The installation must

be on a cold water supply.

Important Note: This system

requires the use of the included

power supply (24 VDC).

Important Note: The manually

operated bypass valve enables

the conditioner to be isolated

from the water service line for

maintenance and service. It

also maintains the continuity of

the water supply when the

conditioner is disconnected.

Salt Requirements

Two salt types are recommended for water conditioners:

Block Salt: Water conditioner block salt is reasonably priced, low in

impurities, and will not cake in the salt container.

Solar Salt: Solar salt is reasonably priced and low in impurities.

Resin Cleaners

It is always wise to provide preventative maintenance for your system.

If small amounts of iron are present in your water, use a salt

containing iron remover or add RainSoft water conditioner cleaner to

the salt tank when adding salt. If an excessive amount of iron is

present in your water, we recommend the installation of an iron filter

before the conditioner. See your RainSoft Dealer for details.

Maintenance Requirements

Cleaning the Regeneration Valve

The regeneration valve body is designed to last a lifetime, but from

time to time it may be necessary to clean and lubricate the moving

parts. Your water quality and the amount of regenerations necessary

will affect this maintenance schedule. Your local RainSoft Dealer is

knowledgeable in the different water qualities and will have the neces-

sary parts to complete this service.

Testing Your Water

If you are relying on this system for barium and radium reduction, we

recommend testing your water periodically (2 times a year) with a

hardness test strip (supplied) to ensure that the system is performing

properly, and that hardness, barium, and radium are being reduced*.

Additional hardness test strips are available at no charge from

RainSoft. Please call 1-800-860-7638 for your free two year supply.

In between testing, you can easily monitor the system’s performance

in the shower or while washing your hands. The feeling of soft water

should be present on your skin.

Product Certification Information

The C5 Series is tested and certified by the WQA to NSF/ANSI

Standard 44 for the specific performance claims as verified and

substantiated by test data. Please refer to the performance data sheets

for specific reductions claims.

The C5 Series is tested and certified by WQA to NSF/ANSI 372 for

“lead free” compliance.

The C5 Series is tested and certified by WQA to CSA B483.1

Standard.

Important Note: If you use a

cleaner containing nitric acid or

other strong oxidizing agents,

please use caution and follow

instructions carefully.

Helpful Tip: We recommend that

this service be performed every

three years or earlier if neces-

sary.

Important Note: The supplied test

strip only tests for hardness. A

reduction of hardness is also an

indication that barium and radium

are being reduced*.

* nly the following models are

registered for barium and radium

reduction in the State of

California. EC5 75 CV, EC5 100 CV

and EC5 150 CV. All other models

are not registered in the State of

California for the purpose of

making health claims.

Helpful Tip: Resin cleaner will

prevent the treatment media from

becoming iron fouled.

Important Note: Rock salt is not

recommended for RainSoft water

conditioners. If rock salt is used,

the salt container must be

cleaned out periodically. D N T

USE GRANULATED SALT! The use

of granulated salt may cause

service problems.

Installation Instructions

1. Safety Precautions

• To prevent an accident and/or injury, do not hoist the unit over

your shoulder. Use a hand truck to transport the unit.

• Do not lay the unit on its side.

• Wear safety glasses and work gloves during installation.

2. Test the Raw Water

• If water contains iron, manganese or hydrogen sulfide, a seperate

iron removal system is suggested to be installed prior to the

conditioner, consulting with your local dealer.

3. Check the Water Pressure

• Use a pressure gauge to confirm that the water pressure does not

exceed 120 psi. If the water pressure does exceed this limit, install

a pressure regulator on the inlet pipe of the unit. The minimum

water pressure for a conditioner is 20 psi. 60 psi is the optimum

operating pressure.

4. Locate a Site for the System

• There are three primary requirements needed for a site: the main

water source, an air-gap drain and a grounded electrical

connection. Locate the system as close to these items as practical.

Drain lines over 50 feet long, may need to be increased in size to

allow proper flow.

• Place the system in the desired location. The location should have

a level, smooth, and clean surface.

• If the system is located outdoors, protect the unit from direct sun-

light. Direct sunlight can damage the fiberglass and other system

components. If necessary, build a box or shed.

5. Install the Valve Head

• Remove the cap plug from the tank.

• Lubricate the riser pipe O-ring and tank O-ring with the Dow 111

silicone-based lubricant or equivalent.

• Attach the supplied upper basket to the bottom of the control

valve; twist to lock in place. Do not use if water contains any

amount of iron.

Helpful Tip: The drain may be a

floor drain, a sewer trap, utility

sink, vent stack, dry well, etc.,

depending on local plumbing

codes.

Important Note: The system can

only be installed outdoors in

climates that do not reach

freezing levels.

Important Note: Do not over-

tighten the valve to the tank.

Important Note: Not Applicable

for EC5-CAB and SS Models.

Important Note: For Massachusetts

Res dents Only: The Commonwealth of

Massachusetts Plumb ng Code 248 CMR

shall be adhered to. A l censed plumber

shall be used for th s nstallat on.

Figure 1

• Align the upper basket with the riser pipe and slowly lower the

control valve onto the riser pipe, using a twisting motion.

• Align the control valve with the tank. Push down on the control

valve and continue to turn it clockwise until the valve o-ring

seals against the tank.

6. Turn ff the Water and Drain the Plumbing

• Turn off the water at the meter or the pressure tank.

• To drain the plumbing system, open all faucets in the house and

flush the toilets. The water will drain out of the lowest faucet or

outlet.

• Do not sweat pipes with water in them or while attached to the

system; steam will damage the plastic parts in the valve.

• Do not point the soldering torch directly at the mineral tank or

control valve. These composite materials will last a lifetime, but

cannot withstand the intense heat from a torch.

• Avoid short connections of pipe between the system and the

water heater. If you can’t avoid a short connection, move the

system to another location. As a last resort, install a heat trap or

check valve. If this causes “water hammer”, install a water

hammer suppressor.

7. Provide Untreated Water for Irrigation or

utdoor Watering

• If available, run an untreated water line to outside faucet or

provide a hose connection on untreated line prior to system.

8. Install the Pipe Connector (Yoke) to the

Bypass Valve

• Once the plumbing is complete, connect the yoke to the bypass

valve (see figure 2).

• Support all plumbing connected to the yoke.

• Connect the raw water supply to the inlet pipe connection of the

yoke. When looking at the front of the system, the inlet is the

pipe connection on the right side of the valve (see figure 3). The

arrow molded into valve indicates the direction of flow.

• Connect the treated water pipe to the outlet pipe connection on

the yoke. When looking at the front of the system, the outlet is

the pipe connection on the left side of the valve (see figure 3).

The arrow molded into the valve indicates the direction of flow.

Helpful Tip: This procedure will

allow air to enter the plumbing

system.

Important Note: Applicable for

copper plumbing installations.

Important Note: Short connec-

tions of pipe may allow hot water

to back up into the system.

Important Note: The bypass valve

is not designed to withstand heat

from soldering or twisting from

the attached threaded connec-

tions.

Important Note: Too much weight

on the plumbing connections will

cause a leak.

• nsure that the bypass valve is in Bypass position. The valve

handles should be perpendicular to the pipes (see figure 4).

9. Install the Drain Line and Air Gap

(Air Gap Not Supplied)

• For all drain lines, use at least a 1/2 inch I.D. line.

•Connect the drain line to the drain outlet on back of the valve,

opposite the inlet connection (see figure 5). A fitting is required

to connect the female pipe thread to the drain line.

Figure 4

• Run the drain line to the air gap. The air gap must be installed between

the end of the drain line and the drain to prevent possible back siphoning

( see fig 6)

10. Install the Brine Safety Float

• Insert the brine well into the brine tank (see figure 7.1).

• Attach the brine well to the brine tank with the overflow

elbow (see figure 7.2).

• Insert the safety float into the brine well. The top of the safety

float should be about 5 inches from the overflow elbow (see

figure 7.3).

11. Install the Brine Line

• Slide the brass compression nut over the end of the brine line,

followed by the ferrule and tube support. Attach the brine line

to the brass fitting on the right side of the valve (see figure 8).

• Insert a tube support into the other end of the brine line and

push the brine line into the brine safety float elbow. Use a

locking clip to secure the connection (see figure 8)

Important Note: Not Applicable

for EC5-CAB Models.

Important Note: The brine over-

flow line must not be higher than

the overflow elbow on the brink

tank. (This is a gravity overflow.)

This line is used only when other

overflow valves fail.

12. Install the Brine verflow Line (indoors)

• Run a 1/2 inch I.D.brine overflow line from the overflow elbow

on the side of the brink tank to an approved drain (see figure 8).

13. Attach the Electrical Connection

• Insert the barrel plug from the DC power supply into the mating

jack in the back of the control box .

• Plug the DC power supply into a 110 VAC 60 Hz or 230 VAC 50

Hz outlet.

System Start Up

1. Turn on the Water and Check for Leaks

• Close all faucets and turn the water back on at the water meter or

pressure tank.

• Check for leaks. If a leak is present, drain the plumbing again

before soldering.

2. Flush the Remaining Debris from the System

• Open the cold water faucet on your bathtub.

• Allow the system to flush the remaining dirt and debris into the

bathtub, until the water runs clear.

• Open all remaining faucets and allow the plumbing to release any

trapped air in the system.

• Close all of the faucets.

3 pen the Bypass Valve

• Move the bypass valve handles to the service position. The valve

handles should be parallel to the pipes (see figure 9).

• Open a cold water tap and allow the appliance to flush for 20

minutes or until approximately 100 gallons has passed through the

appliance.

Helpful Tip: It is common for

new systems to have some

color in the water. The color

should disappear after you

completely flush the system.

Helpful Tip: This procedure will

prevent dirt and debris from

entering the valve.

Figure 9

4. Flush the Hot Water Heater

• Run hot water in the bathtub until the water tests soft.

5. Add Salt to Brine Tank

Salt Recommendations

RainSoft Water conditioners use water softener Block Salt, Solar

Salt (Pellet), or Potassium Chloride. Your Dealer will provide a

recommended type of salt to use. Go to the Main Menu, >

Configure Settings, >Salt Settings, to change your Salt Type

(Sodium or Potassium) and Salt Form (Pellet or Block)

Adding Salt to your Brine Tank

1) Fill your Salt Tank with Block Salt, Solar Salt (Pellet) or

Potassium Chloride. The RainSoft standard brine tank can hold a

max of 250 lbs. [113kg] or L V L 5.0 of Pellet form Salt and 200

lbs. [90kg] or Level 4.0 of Block form Salt.

• Solar Salt and Potassium Chloride generally come in 40 lbs. Pellet

Form Bags. Fill tank with pellets by empting contents right into

center of brine tank.

• Block Salt comes in 25 lbs. blocks or 50 lbs. blocks. See Block

Stacking Figures on page 14 for correct and incorrect stacking

of block salt.

2) On your C5, press any button from the home screen to enter

the Main Menu, then select >SALT L V L, Press nter or Right

Arrow button. Using the Up and Down Arrows, set the Salt Level

to the level of salt that is filled in the brine tank. You can

reference the weight of salt you entered for more precise

entering of amount of salt used. Level of 1.0 is equal to 50 lbs.

22kg] of salt.

3) Press nter Button to save new salt level and exit salt level

screen. Press the Left Arrow button to exit the Main Menu and

return to the Home Screen.

Note: Exiting Salt Level screen with the Left Arrow button will

NOT save new salt settings.

Important Note: It is important

to maintain at least 15 lbs. to 30

lbs. of salt in your brine tank to

correctly regenerate your

System and to continue to enjoy

soft water. L W SALT ALERTS

will activate for salt levels

under 30 lbs.

Recommendations: If choosing to

use both Block and Pellet form of

salt when filling your brine tank,

we recommend you maintain your

settings on Pellet Form. We do not

recommend this method of filling

your brine tank for system sizes of

EC5 150 and higher. The total

volume of salt in the full brine

tank will not allow enough room

for water to make the appropriate

amount of brine solution to

regenerate your system fully.

6. Sanitize the Conditioner

• Mix a 3/4 cup of common (unscented) 5.25% household bleach

with 1 quart of water. Pour this solution into the brine well.

• Initiate a manual regeneration. The solution will be drawn into the

conditioner during the regeneration process.

• After the system has completed a manual regeneration, the condi-

tioner will be sanitized and ready for use.

Important Note: Do not pour

undiluted bleach into the water

conditioner.

An verview of the Regeneration

Process

Your RainSoft C5 Water Conditioner performs a periodic regeneration

cycle to clean itself and restore its capacity. How often it regenerates

depends on your water use, incoming water hardness, and several other

factors, but 1 - 2 times a week is typical. An automatic regeneration will

never occur more than once in a day, and is programmed to occur at a time

when you are unlikely to be using water (late at night in most cases). The

time of regeneration is adjustable via the control interface or customer app.

Here is an overview of the regeneration process:

CYCLE 1- Brine Fill

The first step in preparation for the regeneration is to add water to the

brine tank. The amount of salt the conditioner uses in its regeneration is

directly related to the amount of water added to the brine tank. The salt

will only dissolve into the water until it reaches a point of saturation, then

no matter how much longer it sits, no additional salt will dissolve. Many

softeners add a fixed amount of water to the brine tank at the end of each

regeneration cycle. With that type of unit, the water sits in the tank until

the next regeneration, usually for several days.

Your C5 conditioner uses a more sophisticated and efficient approach

called "proportional brining." The computer continually monitors your

water use and decides if regeneration is needed today. If regeneration is

needed, the computer moves the valve to the brine refill position about two

hours before the scheduled time of regeneration. You may hear the motor

running and some water flowing at this time. Because the computer knows

how much water you've used, it calculates the exact amount of salt that will

be needed to completely restore the system capacity. Then it adds just

enough water to the brine tank to dissolve that much salt. So you can say

it creates brine in proportion to the amount of capacity you need to restore

it doesn't waste salt.

EXAMPLE: If the time of regeneration is set for 2:00 AM, you may hear

the system apparently start to regenerate at 12.00 AM. What it is actually

doing is running the brine fill cycle. It will fill the brine tank for a few

minutes, then return to its normal home position for 2 hours. The actual

full regeneration cycle starts just after 2:00 AM. (See regeneration time line

example below)

11:30 PM 5:30 AM

Notes:

1) Cycles 1 and 4 times are variable times precalculated before the regeneration process begins based on current resin capacity.

2) Times listed are example times.

Example: Regeneration Timeline

CYCLE 2- Brine Make Up/Service

After adding water to the brine tank, the valve returns to home posi-

tion and waits for two hours. This time is adjustable, but two hours

provide the optimum solution. This gives the salt plenty of time to

dissolve and ensures that an accurate salt dose is used. The system is

still providing treated water to your home during this cycle.

CYCLE3- Backwash

At the programmed time of regeneration, the valve moves to its back-

wash position for the start of its actual regeneration cycle. In the back-

wash position, the normal flow through the pressure tank is reversed,

with water flowing from the bottom up, so that the softening mineral

is lifted and cleaned. This removes any dirt or particles that have

accumulated on the top of the mineral bed. As is true of the entire

regeneration cycle, all the water flowing through the tank at this point

is sent directly to the drain. None of the regeneration water enters

your supply pipes. If you use any water during regeneration, the

system provides you with untreated water that completely bypasses

the tank.

CYCLE 4- Brine Draw / Slow Rinse

After the system is backwashed for several minutes, the valve moves to

the brine draw position. In this position, the valve creates a vacuum

to pull the brine solution out of the brine tank. The brine solution

flows slowly through the mineral bed, removing the hardness ions that

are attached to the softening resin and sending them to the drain.

After all the brine is drawn out of the brine tank, the system continues

to slowly rinse the mineral bed, giving plenty of time for all the resin

beads to be recharged and rinsing out any excess brine

CYCLE 5-Fast Rinse

The valve then moves to its final regeneration cycle, in which water

flows quickly through the bed in its normal direction from top to

bottom. This settles the mineral bed back down and serves as a final

cleaning rinse. The valve then returns home. The regeneration cycle

is complete.

NOTE: The entire regeneration cycle, from backwash to fast rinse,

takes one to two hours in most cases

MANUAL REGENERATI N:

Although it may never be necessary, you always have the option

to start an immediate regeneration. See page 20 for instructions.

The manual regeneration will start with brine tank fill and a 2

hour soak cycle as described above. Since a manual regenera-

tion is primarily intended to recover from unusual circum-

stances, such as allowing the brine tank to run out of salt, it is

assumed that you need to recover full capacity. Therefore, a

manual regeneration always uses the maximum salt dose for

your size of unit.

Navigating the Menus

The C5 control uses a simple layout of up/down & left/right buttons

in a cross pattern with an enter button in the center. We hope you will

find this system intuitive and familiar, since it is similar to TV remote

controls and other devices you already have.

We encourage you to just try it out and consult this section of the

manual if you have questions. A full description of the menu struc-

ture follows for those who prefer to understand the details first.

The home or normal screen looks like this:

This is the screen you will see most of the time when you first walk up

to the system. There are a few special screens that will be described in

the “R G N RATION” and “ALARMS” sections of this manual.

The screen has a backlight that turns off after a few minutes of no

activity. Pressing any button when the screen in not lit automatically

turns the backlight on. That first button press doesn’t do anything

else, so don’t worry – you can’t press the wrong button.

When you’re on the home screen and the backlight is on, pressing any

button will take you to the main menu screen. Again, you can’t press

the wrong button – they all take you to the same place.

The Main Menu screen looks like this:

• When salt level reaches 0, the low salt alert is replaced by a

NO SALT alarm. This alarm condition will persist until you

add salt and adjust the salt level.

• When you lose power, a POW R LOSS event is noted. The

system will record the time power is lost & the time power is

restored. You do not need to do anything in response to a

power loss. The system can keep time for several days

without power and will not lose any settings in a power loss.

The computer has automatic recovery procedures for power loss

during a regeneration.

• If the motor is unable to drive the valve to its proper position

during regeneration, a MOTOR/SWITCH alarm is activated.

This alarm indicates a serious issue with the drive assembly or

valve and requires service by a trained technician.

• Other RainSoft products in your home, such as a drinking

water system and a whole house filter, have filter elements or

other components which eventually become exhausted and

need replacement. Your C5 control can be set to monitor

these system and provide a warning when service is needed.

These alarms are identified as DRINKING WAT R, FILT R,
