INTRODUCTION
Congratulations! You have purchased one of the highest-quality water softener/conditioner systems
available today. Your new water softener/conditioner is very efficient in its salt and water usage. The
system is completely automatic and will contribute to better and longer service of all your water-using
appliances. There is very little maintenance required for a water softener/conditioner, and it can give you
many years of trouble-free use. This system has been engineered with the finest-quality components and
materials. You’ll soon be enjoying better water quality and the personal benefits that come from soft/
conditioned water use
IMPORTANT: ONLY USE ON POTABLE WATER SUPPLIES
Read entire manual before attempting installation or routine service.
Obtain all materials and tools needed for installation before starting.
Installation requires soldering copper plumbing fittings. If you don’t possess
soldering skills, seek professional installation service.
System and installation must be in compliance with state and local
laws and regulation.
Benefits of Soft/Conditioned Water
1. Save up to 30% of the cost of hot water heating.
2. Reduce dishwashing detergent use up to 75%. See dishwasher owner’s manual for proper amount of
soap at “0” softness.
3. Reduce use of all soaps and cleaning products up to 75%. You may be able to use less shampoo,
conditioners and skin lotions.
4. Reduce laundry soap use up to 75%. Typically, a one-quarter cup to one-half cup of standard laundry
detergent is recommended.
5. Reduced cleaning time and effort. Many people report that their cleaning time is cut in half.
6. The silky-smooth feeling you may experience while rinsing the soap off your skin during a shower is
your natural body oils. Soap actually rinses off much faster with soft/conditioned water, but you may
not feel like the soap is rinsed off because of this slick feeling. You will find that if you shower in hard
water again, it will feel sticky and unclean. Enjoy the fresh, new showering experience; and
remember, you don’t need as much soap now!
7. There are many other benefits of soft/conditioned water that you can now start to enjoy. Studies have
indicated that savings from a softener/conditioner can easily range from $10.00 to $30.00 per month.
Start to experience the benefits of soft/conditioned water now! We hope you enjoy!

INSTALLATION INSPECTION
IS YOUR HOME PRE-PLUMBED?
Your home is pre-plumbed for a water softener/
conditioner if you have a loop in the garage or
laundry room. A pre-plumb consists of a 110-volt
outlet within 6 feet of the loop and a 1/2” drain line
stubbed out of the wall. All three components are
required. If your home is pre-plumbed, skip now to
Step 1 of Installation Procedures.
CAUTION: Before starting up system, check water
softener drain line to insure that it will drain
properly.
IF YOUR HOME IS NOT PRE-PLUMBED
If your home is not pre-plumbed for a water softener, then we recommend calling for professional
installation. If you are attempting to install the system yourself, you must determine where to locate the
water softening/conditioning system.
The best location depends on several questions:
1. How will you get the water from the water main to the water softener/conditioner?
2. Where will you run the drain line/waste tube? (See illustration on page 5)
3. Where is a 110V outlet within 6 feet of the softener?
Optional: Use a 24-volt timer motor and transformer.
Or run a longer wire to most any 110V outlet.
4. Do you need to run a hard-water line to your outside hose bibs, pool fillers or
irrigation system?
1. Where can the water softener sit on a firm, fairly level concrete floor or slab?
Determine the location of your water softener/conditioner, taking into account the above factors, and
determine what materials and tools will be needed for installation. You are now ready to move on to Step
1 of the installation procedures.
Form ETWS 2/07 Page 5 of 20

INSTALLATION PROCEDURES
STEP 1 – CONNECT TO WATER SUPPLY
A. Prepare the water softener valve for installation.
1. Remove the two red H-clips from the control valve to allow installation of the bypass valve.
Use a small screwdriver to pry the H clips up and off the valve.
2. Apply non-petroleum silicone lubricant to the two connection ends on the bypass valve.
3. Push the bypass assembly into the control valve.
4. Install the two red plastic H-clips from the top of the bypass valve. Push the H-clips all the
way down until they snap into place.
5. The brass connectors should already be installed in the bypass valve. If they are not, push the
two brass connectors in place into the bypass valve and install the two H-clips.
6. Put the bypass valve into the bypass position by turning both sides of the valve to the bypass
position as shown on top of the bypass valve.
Note: The valve comes with two extra red H-clips and one extra gray clip for the brine line
connector.
B. Prepare the softener loop for installation.
1. Shut off the main water supply to the house.
2. Open the hose bib to relieve pressure and drain out excess water.
3. Place a bucket or the softener brine tank under the softener loop to catch the excess water that
will spill out when you cut the pipe.
4. Cut the plumbing loop off.
5. Determine the inlet side of the loop by turning the main water on very slightly until water
comes out of one of the sides of the loop. This is the inlet supply. Warning: You must
connect the incoming side of the softener/conditioner to the inlet supply from the loop.
Failure to connect with the proper directional flow can damage the water softener/conditioner
and your household plumbing.
Form ETWS 2/07 Page 6 of 20

C. Make the plumbing connections to the water supply.
1. Protect the control valve from the heat generated from soldering by wrapping a wet towel
around the bypass valve near the brass connectors while soldering the joints away from the
valve.
2. Connect the inlet supply side of the loop to the inlet connector on the bypass valve. A
directional arrow on the top of the bypass valve designates the inlet.
3. Connect the outlet from the valve to the outlet side of the loop.
STEP 2 – CONNECT TO DRAIN
We recommend using ½” I.D. black drip-line sprinkler tubing for the drain line run, (not provided).
A typical drain line runs from a ½” copper stub out located at the softener loop to a washing machine drain.
Sometimes the softener will drain to a floor drain, sanitary sewer line with a p-trap, a sink drain, or a sump.
CAUTION: Check with all local plumbing codes to insure proper installation in your area. An air-
gap is required. Be sure to install proper drain line size (see specifications or step 2D for sizing).
A. Push one end of the ½” I.D. drain-line onto the drain-line hose barb fitting located on top and
behind the controller.
B. Secure the tube with a hose clamp, (not provided).
C. Connect the tubing to the drain stub out provided with your pre-plumb loop. Some pre-plumbs
may provide an ABS drainpipe to run the drain-line to. CAUTION: Be sure the drain-line
discharges properly into a drain to prevent flooding.
D. If the following conditions exist, it is recommended to increase the drain line tubing from ½” to
¾” I.D.
1. Drain line run is over 20’.
2. Drain line vertical rise is over 10 feet above the water softener with incoming water supply
pressure of 60 psi. (You can increase or decrease height of run 2 feet per 10 psi. variations in
either direction, i.e. 12 feet vertical run with 70 psi. or 8 feet vertical run with 50 psi.).
STEP 3 – ASSEMBLE THE BRINE TANK AND CONNECT THE BRINE LINE
A. Take off the cap from the brine well.
B. Take out the float assembly.
C. Place the brine well into the brine tank and align the holes in the brine well to the holes in the
brine tank.
D. Take out the 1/2" 90° elbow hose barb and remove the rubber washer and plastic nut.
E. From the outside of the brine tank, install the elbow fitting through the bottom hole.
F. Place the rubber washer onto the threads inside the brine well and secure with the plastic nut.
G. Remove the nylon nut from the float assembly; insert the float assembly inside the brine well with
the bolt through the small hole opposite the elbow fitting. Secure with the nylon nut.
H. Connect one end of the 3/8” black line to the brine float fitting located at the top of the brine well
inside the brine tank. Note: The brine line enters the brine tank through the hole aligned with the
fitting for the brine float.
I. Connect the other end of the 3/8” black line to the brine line flow control fitting located just
behind the control head using the black nut provided. The line enters from the left side facing the
control.
J. Be sure all fittings and connections are tight. (See diagram on page 17).
STEP 5 – CONNECT THE ELECTRICAL
A. Plug the transformer into a 110 VAC outlet that is NOT controlled by a wall switch.
B. The display will now alternately display the time of day and capacity remaining.
STEP 4 – START UP THE SYSTEM
Form ETWS 2/07 Page 7 of 20

A. Make sure when opening the valves to allow water to enter the softener for the first time that you
open the valves slowly and allow the water to fill the softener very slowly.
B. Verify that the bypass valve is in the bypass position.
C. Turn on the water supply to the house slowly and check for leaks in the soldered connections. If
there are leaks, repair before continuing with start-up.
D. Put about 4 inches of water in the brine tank.
E. Open a nearby faucet in the house.
F. Slowly open the inlet knob on the bypass valve. Then slowly open the outlet knob on the bypass
valve.
G. Locate the Extra Cycle Button on the lower left corner of the control display.
H. Press and hold the Extra Cycle Button until the display shows a flashing “1”, approximately 5
seconds. The “1” will stop flashing when it advances to the proper position.
I. The water will be flowing to the drain in this first cycle.
J. Check the drain discharge to verify the water is draining into the drain properly.
K. Let water run to the drain for about 3 or 4 minutes.
L. Turn off the faucet in the house.
M. Press the Extra Cycle Button again to advance the controller to the next stage, Brine Draw.
N. The display will show a flashing “2”. Again the “2” will stop flashing after a few seconds.
O. The valve will be drawing water out of the brine tank very slowly during this stage. Watch the
water level and see that it is indeed drawing out the water.
P. Allow the valve to run in this cycle for about 2 minutes.
Q. Press the Extra Cycle Button again. A flashing “3” will be displayed.
R. After the “3” stops flashing, press the Extra Cycle Button again. A flashing “4” will be
displayed.
S. After the “4” stops flashing, press the Extra Cycle Button again. A flashing “5” will be
displayed.
T. Leave the valve in this cycle, Brine Refill. This cycle will fill the brine tank with water. The
control will automatically cycle itself back to the In Service position after about 12 minutes.
U. Once the valve is in the In Service position proceed to the next step, Programming the Valve.
STEP 6 – PROGRAM THE VALVE CONTROL
Form ETWS 2/07 Page 8 of 20

A. Set the Time of Day Setting.
1. Locate the up and down buttons on the face of the control valve.
2. Simply push the up button to set the time forward, or the down button to set the time
backward. On the right of the display there is a P.M. indicator dot. Holding the button in
will advance the time more quickly. It will start slow at first, and then increase in speed
the longer you continue to hold the button in.
3. Release the buttons when you have set the control to the current time of day.
B. Program the feed water hardness.
1. Enter the programming mode by pressing both the up and down buttons for (5) seconds.
2. The first setting displayed is the feed water hardness listed in grains per gallon. The
factory default value is 18 grains.
3. Change the setting to the feed water hardness in your area by pushing the up or down
button. We recommend setting the value about 3 grains higher than what the actual level
is to compensate for seasonal changes in the feed water hardness. You can find out what
your feed water hardness is by contacting the municipality or company providing the
water service to your home.
4. Press the Extra Cycle button to advance to the regeneration time setting.
C. Program the regeneration time.
1. The factory default regeneration time setting is 2:00 A.M.

USE AND CARE
A. Type of System
Your water softener is a fully automatic Demand Initiated, metered system. This means the
softener meters, or keeps track of, the water used in the home. It uses this information to
determine when to perform the regeneration, or cleaning cycle. The control of the softening
process automatically adjusts to your water use. For example, if you have company and your
water use increases substantially, the softener will adjust to insure you don’t run out of soft water.
If you go away for a time and are not using any water in the home, the softener will adjust again
and not perform a regeneration cycle thereby saving salt and water.
B. Type of Salt
Basically, salt is salt. However, some makes of salt contain more dirt in the bag than others. We
recommend Morton™ or Diamond Crystal™ salt pellets, but any type will work. Salt is readily
available at most grocery stores and home improvement centers.
C. Type of Potassium
Potassium can also be used in the water softener. When Potassium is used however, the softener
control valve will need to be adjusted. Add 3 grains to the feed water hardness setting i.e. feed
water = 18 grains + 3 for potassium = 21 grains entered for the feed water setting. Also keep the
level of potassium in the brine tank low.
D. Amount of Salt or Potassium
We recommend keeping the level of salt in the brine tank about half full for most households.
Larger households can start out with more. Let the salt level drop down to the water level before
adding more salt. Potassium should be kept as close to the water level as is practical to help
prevent a “salt bridge”. Periodically you may experience a salt bridge. A salt bridge occurs when
Form ETWS 2/07 Page 9 of 20

the salt forms a crust right at the water level in the brine tank. The salt remains suspended above
the water and cannot make the brine solution required for the regeneration of the softener bed. If
you do experience a salt bridge, simply tap a broom handle down in the salt to break up the bridge.
Wait at least 1 hour, and then manually regenerate the softener.
E. Sodium and Potassium in Softened Water
The softening process does add some sodium or potassium to the conditioned water. The
following chart shows approximately how much sodium or potassium is added to one quart of
conditioned water based on the amount of feed water hardness.

For comparison, (2) slices of white bread contain approximately 278 milligrams of sodium and (2)
cups of milk contain approximately 226 milligrams of sodium. One large banana contains
approximately 600 milligrams of potassium.
F. Noise during the regeneration cleaning process
The water softener will automatically perform a cleaning process called regeneration. During
regeneration the softener will cycle through several stages including backwash, brine rinse, rapid
rinse, and brine refill. There may be considerable noise coming from the valve control during this
process. The regeneration process will take approximately (2) hours to complete. The default
time of day when the regeneration takes place is 2:00 A.M. If this time proves disruptive to you,
program the valve to regenerate at a different time of day. See step 6, page 9.
G. Cleaning the Brine Tank
Normally it is not necessary to clean the brine tank. In time dirt and silt can build up in the brine
tank and if you choose you can clean it out. Let the salt level drop down very low. The night
before you clean, manually regenerate the softener. Disconnect the brine line and dump out the
old salt, (Do not dump the old salt anywhere near living plants). Reconnect the brine
line, add about (3) gallons of water, and add the new salt.
H. Changing the Control Valve Settings
It is not necessary to change the control valve settings other than the ones described in step (6).
Over the course of several months it is possible the display will not show the correct time of day
due to power fluctuations. Reset the control to the correct time of day. If your feed water
hardness changes, reset the control to the new hardness. Other settings are programmed at the
factory for optimum efficiency and do not need to be changed.
I. Bypassing the Softener
You may need to bypass the softener for service or if you do not want your household water to
pass through the softener. See the diagram in step (1) for instructions on bypassing the softener.
The instructions are also shown on top of the bypass valve. Make sure you depressurize the
system before performing any service or removing the softener. See the “WARNING” in the
troubleshooting section below.
J. Vacations or extended periods of non-use
It is not necessary to shut down the softener for periods of non-use equal to two-week to one-
month vacations. If however, you are a temporary resident and leave for periods of four to six
months, we recommend you shut the softener down. Put the softener in bypass and unplug it.
When you return you will need to start the softener up. Make sure there are approximately (3)
gallons of water in the brine tank, plug the softener in, and manually regenerate the softener.
K. Disinfection of the Water Softener
Form ETWS 2/07 Page 10 of 20

The materials of construction of the modern water conditioner will not support bacterial growth,
nor will these materials contaminate a water supply. However, during normal use, a conditioner
may become fouled with organic matter, or in some cases with bacteria from the feed water
supply. This may result in an off-taste or odor in the water.
Therefore, your conditioner may need to be disinfected after installation. Some conditioners will
require periodic disinfection during their normal life. Consult your installing dealer for more
information on disinfecting your conditioner.
Depending upon the conditions of use, the style of conditioner, the type of ion exchanger, and the
disinfectant available, a choice can be made among the following methods.
Sodium or Calcium Hypochlorite
These materials are satisfactory for use with the polystyrene resin in your water softener.
5.25% Sodium Hypochlorite
These solutions are available under trade manes such as Clorox™. If stronger solutions are used,
such as those sold for commercial laundries, adjust the dosage accordingly.
1. Dosage 2-F70MDV-342 / ET42H 1.5 fluid ounce
2-F70MDV-350 / ET50H 1.8 fluid ounce
2-F70MDV-364 / ET64H 2.4 fluid ounce
2. Application
a. Manually put the water softener into regeneration.
b. Let the softener proceed through the first cycle, about (10) minutes.
c. Add the sodium hypochlorite solution to the brine well inside the brine tank.
d. Let the softener proceed with the regeneration process.
Calcium Hypochlorite
Calcium hypochlorite, 70% available chlorine, is available in several forms including tablets and
granules. These solid materials may be used directly without dissolving before use.
1. Dosage 2-F70MDV-342 / ET42H 2.5 grains (approximately 0.13 ounce)
2-F70MDV-350 / ET50H 3 grains (approximately 0.15 ounce)
2-F70MDV-364 / ET64H 4 grains (approximately 0.20 ounce)
2. Application
a. Manually put the water softener into regeneration.
b. Let the softener proceed through the first cycle, about (10) minutes.
c. Add the sodium hypochlorite solution to the brine well inside the brine tank.
d. Let the softener proceed with the regeneration process.
TROUBLESHOOTING
The technology upon which the control valve is based is well established and proven in service
over many years. However, should a problem or question arise regarding the operation of the system, the
control can very easily be serviced.
WARNING: The water softener operates under house pressure and can be as high as 80 psi. The control
valve must be depressurized before servicing. The best way to depressurize the system is:
•Turn off service to the house.
•Open a hose bib or faucet in the house to relieve pressure.
•Put softener valve into the bypass position.
•The softener is now depressurized and service may be turned back on to the house.
