The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to perform control
valve repairs or maintenance. The 1” full flow bypass valve incorporates four positions, including a diagnostic position that allows a
service technician to have pressure to test a system while providing untreated bypass water to the building. Be sure to install bypass
valve onto main control valve, before beginning plumbing. Or, make provisions in the plumbing system for a bypass. The bypass body
and rotors are glass-filled Noryl® and the nuts and caps are glass-filled polypropylene. All seals are self-lubricating EPDM to help prevent
valve seizing after long periods of non-use. Internal “O” Rings can easily be replaced if service is required.
The bypass consists of two interchangeable plug valves that are operated independently by red arrow shaped handles. The handles
identify the direction of flow. The plug valves enable the bypass valve to operate in four positions.
1. NORMAL OPERATION POSITION: The inlet and outlet handles point in the direction of flow indicated by the engraved
arrows on the control valve. Water flows through the control valve for normal operation of a water softener or filter. During the
regeneration cycle this position provides regeneration water to the unit, while also providing untreated water to the distribution
system (Fig. 1).
2. BYPASS POSITION: The inlet and outlet handles point to the center of the bypass. The system is isolated from the water
pressure in the plumbing system. Untreated water is supplied to the building (Fig. 2).
3. DIAGNOSTIC POSITION: The inlet handle points toward the control valve and the outlet handle points to the center of bypass
valve. Untreated supply water is allowed to flow to the system and to the building, while not allowing water to exit from the system
to the building (Fig. 3). This allows the service technician to test the unit and perform other functions without disrupting the water
going to the building.
NOTE: The system must be rinsed before returning the bypass valve to the normal position.
4. SHUT OFF POSITION: The inlet handle points to the center of the bypass valve and the outlet handle points away from the
control valve. The water is shut off to the building. The water treatment system will depressurize upon opening a tap in the building.
A negative pressure in the building combined with the unit being in regeneration could cause a siphoning to the building. If water
is available on the outlet side of the unit, it is an indication of water bypassing the system (Fig. 4) (i.e. a plumbing cross-connection
somewhere in the building).

INITIAL CONTROLLER SET-UP
The manufacturer has preset the unit so that the gallons between regenerations will be automatically calculated
after the hardness is entered. Press NEXT to cycle to the next step or REGEN to return to the previous step.
STEP 1 – Press and hold the NEXT and
+ buttons simultaneously for 3 seconds.
STEP 2 – HARDNESS: Use the
+ or – buttons to adjust the hardness value in grains per gallons. Adjustable
from 1 to 150 gpg in 1 grain increments (default setting is 20).
The hardness value is based on the actual compensated hardness of the water and must be set by
an authorized dealer following an on-site water analysis. Adjusting the number will only impact the
frequency of regeneration and will not alter or affect the hardness of the water treated by the unit.
Note: If a resin media is used, increase the grains per gallon if soluble iron is present
(1 ppm = 4 gpg). This screen will not display if “FILTER” mode is selected.
STEP 3 – DAYS BETWEEN REGENERATION (DAY OVERRIDE): Use the
+ or – buttons to adjust the day
override. Adjustable from 1-28 days or OFF. The manufacturer has factory set 10 days as the default.
The Day Override value represents the maximum number of days between regenerations. If any number
is set (1-28 days), a regeneration will be scheduled for that day if the gallon capacity has not been met. If
OFF is set, the unit will only initiate a regeneration once the gallon capacity has been met.
STEP 4 – REGENERATION HOUR: Use the
+ or – buttons to adjust the time of day the unit will regenerate.
AM/PM toggles after 12. The manufacturer has factory set 2:00 A.M. as the default setting which is
recommended for a normal household.
STEP 5 – REGENERATION MINUTES: Use the + or – buttons to set minutes.
STEP 6 –
SERVICE ALARM GALLONS: Use the + or – buttons to schedule a service alarm by gallons. Adjustable in
100 gallon increments or OFF. The manufacturer has factory set OFF as the default.
This feature is typically set by the installing dealer to warn the homeowner that service is required after
a number of gallons have been consumed. If the feature is active, a specific gallon amount will appear.
For more information regarding how to set service alarms, the installer should consult the master
programming guide that corresponds to the unit being installed.
Press the NEXT button three times to advance to the next screen.
STEP 7 – SERVICE ALARM TIME: Use the + or – buttons to schedule a service alarm in years. Adjustable in .25
year increments or OFF. The manufacturer has factory set OFF as the default.
This feature is typically set by the installing dealer to warn the homeowner that service is required after
an amount of time has passed. If the feature is active, a specific number of days will appear. For more
information regarding how to set service alarms, the installer should consult the master programming
guide that corresponds to the unit being installed.
Press the NEXT button three times to advance to the next screen.

If the system has called for a regeneration that will occur at the preset time of regeneration, the words “REGEN TODAY” will appear on the display.
If a water meter is installed, “GPM” flashes on the display when water is being treated, indicating gallons per minute flowing through the system.
2. GENERAL NAVIGATION
During normal operation, the default user displays are “time of day” and “gallons per minute”. Flow rate, vacation mode, capacity remaining, and
days to a regeneration are optional displays. For more explanation, consult the “operating displays and maintenance section”. Pressing the NEXT
button on a general operating screen will cycle through the available operating displays.
In any screen other than a general operating display, the NEXT button will proceed to the next step, the REGEN button will return to a previous
step, and the CLOCK button will return to the general operating displays. Any changes made prior to the exit will be incorporated. If no buttons
are pressed within five minutes, the display will return to the general operating displays.
4. REGENERATION AND STANDBY DISPLAY: Typically, a system is set to regenerate at a time of no water usage. If there is a demand
for water when the system is regenerating, untreated water will be delivered. When the system begins to regenerate, the display will include
information about the step of the regeneration process and the time remaining for that step to be completed. The system runs through the steps
automatically and will reset itself to provide treated water when the regeneration has been completed.
In multi-valve installations, a unit will display “standby” in the top-left corner of the screen when it is inactive. The screen will return to a general
operating display or a regeneration display once the unit is called back into service.
3. DOUBLE REGENERATION
Two generations within 24 hours are possible with a return to the preset program. To initiate a double
regeneration:
1. Press the REGEN button once. “REGEN TODAY” will flash on the display.
2. Press and hold the REGEN button for three seconds until a regeneration begins.
Once the valve has completed the immediate regeneration, the valve will regenerate once more during the
preset time.
5. MANUAL REGENERATION: Sometimes there may be a need to regenerate a unit before the control
valve calls for it. This may be needed if a period of heavy water use is anticipated or when the system has
been operating without salt.
• To initiate a manual regeneration at the next preset regeneration time, press and release the
REGEN button. The words “REGEN TODAY” will flash on the display to indicate that the system will
regenerate at the scheduled regeneration time (see the Programming Procedures section). If you
pressed the REGEN button in error, pressing the button again will cancel the command.
• To initiate a manual regeneration immediately, press and hold the REGEN button for three seconds.
The system will begin to regenerate immediately. This command cannot be canceled.

6. POWER LOSS AND BATTERY REPLACEMENT: If an extended power outage occurs, the
control valve will retain the time of day settings until the board’s battery is depleted. Once the battery is
depleted, the display will appear dark and absent of any information. If this occurs, following these steps
will determine if the problem is a low battery or a board failure.
To determine if the battery is depleted:
1. Remove valve cover. Disconnect power from PC Board at the four pin connector at the bottom
of the board.
2. Remove battery. Reference the Parts Breakdown section of this manual for location.
3. Wait five minutes for board to de-energize.
4. With the battery out, re-connect the power supply to the board. The board’s display should
begin to show information.
This indicates that the board is operating correctly. If the display does not work, call
installing dealer for service.
5. To replace with new battery, unplug transformer from outlet. Install a 3 volt Lithium Coin Cell type 2032 battery, available at most stores.
Plug unit back into outlet.
It is important to replace the battery with the valve unplugged to avoid causing a short and potentially ruining the board.
6. Reset the time of day (see programming procedures) and initiate regeneration (see operating displays and maintenance).
If these procedures do not remedy the problem, please consult the installing dealer for service.
7. ERROR MESSAGE: If the word “ERROR” appears and flashes alternately with the dealer name and phone
number, record the ERROR number and contact your servicing dealer promptly. This indicates that the control
valve was not able to function properly.
8. BRINE TANK MAINTENANCE AND SALT: Refill the brine tank as necessary, making sure at least 1/3 of
the brine tank is full at all times. Without proper salt levels, the water softener may not operate properly.
Because “typical” settings of this water softener include a dry salt storage feature (no water in brine tank between regeneration), the
manufacturer recommends the use of solar salt for best results. The brine tank is manufactured for the use of solar, pellets or rock salt. Do not use
block salt. If pellet or rock salt is used, a cleaning of the brine tank every six months is recommended. If the dry salt storage feature is not being
utilized, block salt may be used.
Caution: With some models the manufacturer does NOT recommend the use of any resin cleaners, nor placing any resin cleaners into
the brine tank. Furthermore, do not use any salt that indicates it is an iron cleaning salt or that contains any cleaning additives.
This may be harmful to the water softener and for human consumption. Consult dealer for proper cleaning instructions.
9. CHECK SALT INDICATOR AND AUDIBLE ALARM: This control valve is equipped with a low salt
warning to alert homeowners that the system is operating in a low salt condition. This usually indicated that
the salt level in the brine tank is too low to operate properly. If “CHECK SALT” appears on the screen, there will
usually be an audible alarm that sounds also (if turned on), alerting you to these conditions.
TO TURN OFF ALARM: If the audible alarm sounds due to a low salt condition, press any button on the
face of the control valve to turn off. If the salt is not added to the brine tank before
the next regeneration, the CHECK SALT indicator will alarm again.
