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. NUGGET, PELLET or
coarse SOLAR 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 cre-
ate 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 not 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 flow if necessary.
 Softener resins may degrade in the pres-
ence of chlorine above 2 ppm. If you
have chlorine in excess of this amount,
you may experience reduced life of the
resin. In these conditions, you may wish
to consider purchasing a whole house car-
bon filter softener system with a chlorine
reducing media.
 WARNING: Discard all unused parts and
packaging material after installation. Small
parts remaining after the installation could
be a choke hazard.

Before Starting Installation
Tools, Pipe, and Fittings, Other Materials
 Pliers
 Screwdriver
 Teflon tape
 Razor knife
 Two adjustable wrenches
 Additional tools may be required if modifi-
cation to home plumbing is required.
 Plastic inlet and outlet fittings are included
with the softener. To maintain full valve
flow, 3/4” or 1” pipes to and from the sof-
tener fittings are recommended. You
should maintain the same, or larger, pipe
size as the water supply pipe, up to the
softener inlet and outlet.
 Use copper, brass, or PEX pipe and fittings.
 Some codes may also allow PVC plastic
pipe.
 ALWAYS install the included bypass valve,
or 3 shut-off valves. Bypass valves let you
turn off water to the softener for repairs if
needed, but still have water in the house
pipes.
 5/8” OD drain line is needed for the valve
drain. A 10’ length of hose is included.
with some models.
 A length of 5/8” OD drain line tubing is
needed for the brine tank over flow fitting
(optional).
 Nugget or pellet water softener salt is
needed to fill the cabinet or brine tank.
 Continuous operation at flow rates greater than the service flow rate may affect capacity and efficiency performance.
 The manufacturer reserves the right to make product improvements which may deviate from the specifications and
descriptions stated herein, without obligation to change previously manufactured products or to note the change.

 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. Be sure
the electric outlet and transformer
are in an inside 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
5

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 near the valve must be done before connecting any piping to the valve.
Always leave at least 6" (152 mm) between the valve 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 drain pipe. 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.

System Start-Up
1. Plug the power transformer into an ap-
proved power source. Connect the power
cord to the valve.
2. When power is supplied to the control, the
screen will display “INITIALIZING WAIT
PLEASE” while it finds the service position.
3. Manually step the valve past the BRINE
position to the BACKWASH position. If
screen is locked, press SETTINGS for 3
seconds to unlock. Press and hold the
MANUL REGEN. Key for 3 seconds. Press
any key to skip the BRINE cycle.
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 wa-
ter on fully 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.
8. Add salt into the cabinet / brine tank.
9. Program unit.

TIME OF DAY, YEAR,
MONTH, DAY,
Time of day is for normal op-
eration of system and the
scheduling of the regenera-
tion time. The date is used in
a diagnostic function to track
the last time the system re-
generated.
SET HARDNESS
This value is the maximum
compensated water hardness
in grains per gallon of the raw
water supply. It is used to
calculate the system capacity.
If Ferrous Iron is present add
4 gpg for every 1 ppm of Fer-
rous Iron.
SET PEOPLE
This value is the number of
people living in the home. It
is used to calculate the
amount of water needed for
daily use and the reserve ca-
pacity of the system.
SALT SETTING
There are 3 settings to
choose in the MENU SET-
TINGS. These settings will
determine the salt dosage
and capacity for the system.
For SIM units choose IRON &
MN.
WATER TYPE
Select WELL / OTHER if any
Iron or Manganese is present
or if the water source is not
clean (< 1NUT turbidity).
The system will back wash
every time.
REGEN TIME
This setting determines the
time of day to perform a
scheduled regeneration.
REGEN DAYS
This value is the number of
days between regenerations
or back washes to clean the
filters.
GALLONS
Default value is OFF. Adjust
the GALLONS to set the ca-
pacity. This will cause the
unit to regenerate either
when the gallons remaining
goes to zero or the days be-
tween regeneration is zero.

Control 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
The main display page will pause on the Date and Time page for 5 seconds. Then it will continually scroll
through all of the system diagnostic display pages. Depending on the Valve Type some pages will not be dis-
played. To manually scroll through the diagnostics, press the down or up key. To reset the TOTAL REGENS,
TOTAL GALLONS OVER RUN TOTAL, or PEAK flow rates, press and hold the MENU until the value changes to
zero.
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.
