Safety Guide
 Check and comply with your provincial /
state and local codes. You must follow
these guidelines.
 Use care when handling the water soften-
ing system. Do not turn upside down,
drop, drag or set on sharp protrusions.
 The water softening system works on 12
volt-60 Hz electrical power only. Be sure to
use only the included transformer.
 Transformer must be plugged into an in-
door 120 volt, grounded outlet only.
 Use clean water softening salts only, at
least 99.5% pure. NUGGETor PELLET salts
are recommended. Do not use rock, block,
granulated or ice cream making salts.
They contain dirt and sediments, or mush
and cake, and will create maintenance
problems.
 Keep the salt lid in place on the softener
unless servicing the unit or refilling with
salt.
 WARNING: This system is not in-
tended for treating water that is microbio-
logically unsafe or of unknown quality
without adequate disinfection before or
after the system.
For your safety, the information in this manual must be followed to minimize the risk of
electric shock, property damage or personal injury.
Be sure to check the entire softener for any shipping damage or parts loss. Also note dam-
age to the shipping cartons. Contact the transportation company for all damage and loss
claims. The manufacturer is not responsible for damages in transit.
Small parts, needed to install the softener, are in a parts bag. To avoid loss of the small
parts, keep them in the parts bag until you are ready to use them.

Proper Installation
This water softening system must be properly installed and located in accordance with the
Installation Instructions before it is used.
 Do not install or store where it will be
exposed to temperatures below freezing or
exposed to any type of weather. Water
freezing in the system will break it. Do not
attempt to treat water over 100°F.
 Do not install in direct sunlight. Excessive
sun or heat may cause distortion or other
damage to non-metallic parts.
 Properly ground to conform with all gov-
erning codes and ordinances.
 Use only lead-free solder and flux for all
sweat-solder connections, as required by
state and federal codes.
 Maximum allowable inlet water pressure is
125 psi. If daytime pressure is over 80
psi, night time pressure may exceed the
maximum. Use a pressure reducing valve
to reduce the pressure.
 Softener resins may degrade in the pres-
ence of chlorine or chloramines above 2
ppm. If you have chlorine or chloramines
in excess of this amount, you may experi-
ence reduced life of the resin. In these
conditions, you may wish to consider pur-
chasing a whole house carbon filter sof-
tener system with a chlorine reducing me-
dia.
 WARNING: Discard all unused parts and
packaging material after installation. Small
parts remaining after the installation could
be a choke hazard.

needed to fill the cabinet or brine tank.
 Water Temperature = Min 39°F / Max 100°F
 Operating Pressure = Min 35 PSI / Max 125 PSI
 Voltage = 110 volts standard
 Units contain 8% Super Capacity Ion Exchange Resin
At the stated service flow rates, the pressure drop through
these devices will not exceed 15 psig.
 Changing salt settings from factory setting may require
changing injector sizes to achieve stated capacities.
 The manufacturer reserves the right to make product im-
provements which may deviate from the specifications and
descriptions stated herein, without obligation to change
previously manufactured products or to note the change.
How Your Water Conditioner Works
The principle behind water softening is simple chemistry. A water softener contains resin
beads which hold electrically charged ions. When hard water passes through the softener,
calcium and magnesium ions are attracted to the charged resin beads. It's the resulting re-
moval of calcium and magnesium ions that produces soft water.
This system is controlled with simple, user-friendly electronics displayed on a LCD screen.
The main page displays the current time and the remaining gallons in meter mode or the
remaining days in calendar clock mode.

 Place the softener as close as possible to
the pressure tank (well system) or water
meter (city water).
 Place the softener as close as possible to a
floor drain, or other acceptable drain point
(laundry tub, sump, standpipe, etc.).
 Connect the softener to the main water
supply pipe BEFORE the water heater. DO
NOT RUN HOT WATER THROUGH THE
SOFTENER. Temperature of water pass-
ing through the softener must be less than
100 deg. F.
 Keep outside faucets on hard water to
save soft water and salt.
 Do not install the softener in a place where
it could freeze. Damage caused by
freezing is not covered by the war-
ranty.
 Put the softener in a place water damage
is least likely to occur if a leak develops.
The manufacturer will not repair or pay for
water damage.
 A 120 volt electric outlet, to plug the in-
cluded transformer into, is needed within 6
feet of the softener. The transformer has
an attached 6 foot power cable. Extension
cables are available. Be sure the electric
outlet and transformer are in an in-
side location, to protect from wet
weather.
 If installing in an outside location, you
must take the steps necessary to assure
the softener, installation plumbing, wiring,
etc., are as well protected from the ele-
ments, contamination, vandalism, etc., as
when installed indoors.
 Keep the softener out of direct
sunlight. The sun’s heat may soften and
distort plastic parts.
Where To Install The Softener

6
1. If your hot water tank is electric, turn off the power to it to avoid damage to the element
in the tank.
2. If you have a private well, turn the power off to the pump and then shut off the main wa-
ter shut off valve. If you have municipal water, simply shut off the main valve. Go to the
faucet, (preferably on the lowest floor of the house) turn on the cold water until all pres-
sure is relieved and the flow of water stops.
3. Locate the softener tank and brine tank close to a drain where the system will be in-
stalled. The surface should be clean and level.
4. Connect the inlet and outlet of the softener using appropriate fittings. Perform all plumb-
ing according to local plumbing codes.
 Use a ½” minimum pipe or tubing size for the drain line
 ON COPPER PLUMBING SYSTEMS BE SURE TO INSTALL A GROUNDING
WIRE BETWEEN THE INLET AND OUTLET PIPING TO MAINTAIN GROUND-
ING.
Any solder joints being soldered near the valve must be done before connecting any piping
to the valve. Always leave at least 6" (152 mm) between the valve being soldered and
joints when soldering pipes that are connected to the valve. Failure to do this could cause
damage to the valve.
5. Connect the drain hose (10 ft included) to the valve and secure it with a hose clamp (also
included). Run the drain hose to the nearest laundry tub or floor drain. This can be ran
up overhead or down along the floor. If running the drain line more than 20 ft overhead,
it is recommended to increase the hose size to 3/4”. NEVER MAKE A DIRECT CONNEC-
TION INTO A WASTE DRAIN. A PHYSICAL AIR GAP OF AT LEAST 1.5” SHOULD BE USED
TO AVOID BACTERIA AND WASTEWATER TRAVELLING BACK THROUGH THE DRAIN
LINE INTO THE SOFTENER.
6. Using the Allen Key (included), place the unit in the bypass position. Slowly turn on the
main water supply. At the nearest cold treated water tap nearby remove the faucet
screen, open the faucet and let water run a few minutes or until the system is free of any
air or foreign material resulting from the plumbing work.
7. Make sure there are no leaks in the plumbing system before proceeding. Close the water
tap when water runs clean.
8. Open the brine tank / cabinet salt lid and add water until there is approximately 3” (75
mm) of water in the tank. Do not add salt to the brine tank at this time.
9. Proceed to start up instructions.
Note: The unit is not ready for service until you complete the start-up instruc-
tions.

4. Once in the BACKWASH cycle, open the
inlet on the bypass valve slowly and allow
water to enter the unit. Allow all air to es-
cape from the unit before turning the by-
pass fully open. Then allow water to run
to drain for 3-4 minutes or until all media
fines are washed out of the softener indi-
cated by clear water in the drain hose.
5. Press any button to advance to the RINSE
position. Check the drain line flow. Allow
the water to run for 3-4 minutes or until
the water is clear.
6. Press any button to advance to the REFILL
position. Check that the valve is filling wa-
ter into the brine tank. Allow the valve to
refill for the full amount of time as dis-
played on the screen to insure a proper
brine solution for the next regeneration.
7. The valve will automatically advance to the
SERVICE position. Open the outlet valve
on the bypass, then open the nearest
treated water faucet and allow the water
to run until clear, close the tap and replace
the faucet screen.

Operation During A Power Failure
In the event of a power failure, the valve will keep track of the time and day for 48 hours.
The programmed settings are stored in a non-volatile memory and will not be lost during a
power failure. If power fails while the unit is in regeneration, the valve will finish regenera-
tion from the point it is at once power is restored. If the valve misses a scheduled regen-
eration due to a power failure, it will queue a regeneration at the next regeneration time
once power is restored.
Main Display
When power is supplied to the control, the screen will display TIME OF DAY, GALLONS RE-
MAINING, and DEALER NAME and PHONE NUMBER.
The brine tank is equipped with a safety float which prevents your brine tank from overfill-
ing as a result of a malfunction such as a power failure.
Safety Float
New Sounds
You may notice new sounds as your water softener operates. The regeneration cycle lasts
up to 180 minutes. During this time, you may hear water running intermittently to the drain.
About The System
When the system capacity is near exhausted, a regeneration is necessary to restore the sys-
tem to full capacity. The table below explains the regeneration steps.
Regeneration Process
Step Name Description
#1 Back Wash
Fresh water is introduced to the bottom of the tank flowing upwards expanding the ion
exchange resin to rinse out any dirt or small particles to the drain and to un-compact
the bed to restore full service flow rates.
#2 Brine
The brine solution is introduced slowly from the top of the tank flowing down through
the ion exchange resin pushing the hardness out to drain and restoring system capacity.
#4 Rinse
Fresh water is introduced from the top of the tank flowing down through the ion
exchange resin rinsing any excess brine solution out to the drain.
#5 Refill
Fresh water is added to the salt tank to prepare and insure fully saturated brine for the
next regeneration.

11
Automatic Hard Water Bypass During Regeneration
The regeneration cycle can last 30 to 180 minutes, after which soft water service will be re-
stored. During regeneration, hard water is automatically bypassed for use in the household.
Hot water should be used as little as possible during this time to prevent hard water from
filling the water heater. This is why automatic regeneration is set for sometime during the
night and manual regenerations should be performed when little or no water will be used in
the household.
Normal regeneration time is 2:00 AM.
System Configuration
Injector and Drain Line Flow Control

12
Manual Bypass
In the case of emergency, such as an overflowing brine tank, you can isolate your water
softener from the water supply using the bypass valve located at the back of the control. In
normal operation the bypass is open with the on/off knobs in line with the inlet and outlet
pipes.
To isolate the softener, simply rotate the knobs clockwise (as indicated by the word BYPASS
and arrow) until they lock. You can use your water related fixtures and appliances as the
water supply is bypassing the softener. However, the water you use will be hard. To resume
soft water service, open bypass valve by rotating the knobs counterclockwise.
Maintenance
Adding Salt
Use only NUGGETor PELLET water softener salt. Check the salt level monthly. It is impor-
tant to maintain the salt level above the water level. To add salt, simply lift the salt lid and
add the salt directly into the brine tank. Be sure the brine well cover is on and fill only to
the height of the brine well.
Bridging
Humidity or wrong type of salt may create a cavity between the water and the salt. This ac-
tion, known as “bridging”, prevents the brine solution from being made, leading to your wa-
ter supply being hard.
If you suspect salt bridging, carefully pound on the outside of the brine tank or pour some
warm water over the salt to break up the bridge. This should always be followed up by al-
lowing the unit to use up any remaining salt and then thoroughly cleaning out the brine
tank. Allow two hours to produce a brine solution, then manually regenerate the softener.

13
Cleaning or Replacing Injectors
Sediment, salt and silt will restrict or clog the injector. A clean water supply and pure salt
will prevent this from happening.
The injector assembly is located on the right side of the control valve. This assembly is
easy to clean.
1. Shut off the water supply to your softener and reduce the pressure by opening a cold
soft water faucet.
2. Using a screwdriver, remove the two screws holding the injector cover to the control
valve body.
3. Carefully remove the assembly and disassemble as shown above. The injector orifice
is removed from the valve body by carefully turning it out with a large screwdriver. Re-
move the injector throat the same way.
4. Carefully flush all parts including the screen. Use a mild acid such as vinegar or Pro-
Rust Out to clean the small holes in the orifice and throat.
5. Re-assemble using the reverse procedure.

14
Replacing Brine Line Flow Control (BLFC)
1. Remove the red clip that secures the brine elbow.
2. Remove the BLFC holder from the elbow fitting.
3. Split the BLFC holder apart and remove the flow washer.
4. Reassemble using the reverse procedure.
TIP: Markings on the
BLFC washer should face
the direction as shown
here.
Replacing Drain Line Flow Control (DLFC)
1. Remove the red clip that secures the drain line elbow.
2. Remove the BLFC washer from the elbow fitting.
3. Reassemble using the reverse procedure.

15
Care of Your System
To retain the attractive appearance of your new water softener, clean occasionally with mild
soap solution. Do not use abrasive cleaners, ammonia or solvents. Never subject your sof-
tener to freezing or to temperatures above 100°F.
Resin Cleaner
An approved resin cleaner must be used on a regular basis if your water supply contains
iron. The amount of resin cleaner and frequency of use is determined by the quantity of
iron in your water (consult your local representative or follow the directions on the resin
cleaner package).
Sanitizing Procedure
Care is taken at the factory to keep your water softener clean and sanitary. Materials used
to make the softener will not infect or contaminate your water supply, and will not cause
bacteria to form or grow. However, during shipping, storage, installing and operating, bac-
teria could get into the softener. For this reason, sanitizing as follows is suggested when in-
stalling.
Sani-System Liquid Sanitizer Concentrate
Item# 80030021—Softener Sanitizer 0.25 fl.oz (24 Pack)
1. Be sure to complete all installation steps, including programming.
2. For effective and complete sanitization, Sani-System Liquid Sanitizer Concentrate is rec-
ommended. Pour one 0.25 fl. Oz. package into the brine well located in the cabinet or
brine tank. (Alternative use 3/4 oz of common 5.25% household bleach)
3. Start an immediate regeneration. (See page 11)
4. The Softener Sanitizer Solution is drawn into and through the water softener to sanitize
it. This sanitizing regeneration is over in about two hours. Then, soft water is available
for your use.
NOTE: Sanitizing is recommended by the Water Quality Association for disinfecting. On
some water supplies, they suggest periodic sanitizing.
