BYPASS VALVE
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).

GENERAL INSTALLATION & SERVICE WARNINGS
The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments. There is a small amount of “give” to properly
connect the piping, but the water treatment unit is not designed to support the weight of the plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants, or spray silicone anywhere. A silicone lubricant may be used on black “O” Rings, but is not
necessary. Avoid any type of lubricants, including silicone, on red or clear lip seals.
Do not use pipe dope or other sealants on threads. Teflon® tape must be used on the threads of the 1” NPT inlet and outlet and on the threads for
the drain line connection. Teflon® tape is not used on the nut connections or caps because “O” Ring seals are used. The nuts and caps are designed
to be unscrewed or tightened by hand or with the special plastic Service Wrench, #CV3193-02. If necessary, pliers can be used to unscrew the nut or
cap. Do not use a pipe wrench to tighten nuts or caps. Do not place screwdriver in slots on caps and/or tap with a hammer.
SITE REQUIREMENTS
• Water pressure – 30-100 psi • Current draw is 0.5 amperes
• Water temperature – 33-100°F (0.5-37.7°C) • The plug-in transformer is for dry locations only
• Electrical – 115/120V, 60Hz uninterrupted outlet
INSTALLATION
1. The distance between the drain and the water treatment unit should be as short as possible (see #9).
2. Since salt must be added periodically to the brine tank, it should be in an easily accessible location.
3. The media tank should be installed on a firm, level surface (above or below grade).
4. It is NOT recommended to install any water treatment unit with less than 10 feet of piping between its outlet and the inlet of a water heater.
CAUTION: To protect the unit in the event of a hot water heater backup, the manufacturer recommends the use of an expansion tank
on the outlet side of the unit (see diagram).
5. Do not locate unit where it or its connections (including the drain and overflow lines) will ever be subjected to temperatures under 33°F.
6. Do not subject the tank to any vacuum as this may cause an “implosion” and could result in leaking. If there is a possibility a vacuum could
occur, please make provision for a vacuum breaker in the installation.
7. INLET/OUTLET PLUMBING: Be sure to install Bypass Valve onto main control valve before beginning plumbing. If it is desired to
bypass outside hydrants, a cold water kitchen sink, or other locations, provisions should be made at this time. Install an inlet shutoff
valve and plumb to the unit’s bypass valve inlet located at the right rear as you face the unit. There are a variety of installation fittings
available. They are listed under the Installation Fitting Assemblies section of the manual. When assembling the installation fitting package
(inlet and outlet), connect the fitting to the plumbing system first and then attach the nut, split ring and “O” Ring. Heat from soldering
or solvent cements may damage the nut, split ring or “O” Ring. Solder joints should be cool and solvent cements should be set before
installing the nut, split ring and “O” Ring. Avoid getting solder flux, primer, and solvent cement on any part of the “O” Rings, split rings, bypass
valve or control valve. If the building’s electrical system is grounded to the plumbing, install a copper grounding strap from the inlet to the outlet
pipe. Plumbing must be done in accordance with all applicable local codes.

8. INSTALLING GROUND: To maintain an electrical ground in metal plumbing of a home’s cold water piping
(such as a copper plumbing system), install a ground clamp or jumper wiring.
NOTE: If replacing an existing unit, also replace the ground clamps/wire. If removing a unit, replace
the piping with the same type of piping as the original to assure plumbing integrity and grounding.
9. DRAIN LINE: First, be sure that the drain can handle the backwash rate of the system. Solder joints near
the drain must be done prior to connecting the drain line flow control fitting. Leave at least 6” between
the drain line flow control fitting and solder joints. Failure to do this could cause interior damage to the
flow control. Install a 1/2” I.D. tube to the Drain Line Assembly in accordance with plumbing regulations or
discard the tubing nut and use the 3/4” NPT fitting for rigid pipe (recommended). If the backwash rate is
greater than 7 gpm, use a 3/4” drain line. Where the drain line is elevated but empties into a drain below the
level of the control valve, form a 7” loop at the discharge end of the line so that the bottom of the loop is level with the drain connection on the
control valve. This will provide an adequate anti-siphon trap. Piping the drain line overhead <10 ft is normally not a problem. Be sure adequate
pressure is available (40-60 psi is recommended). Where the drain empties into an overhead sewer line, a sink-type trap must be used with
appropriate air gap (see drawing). Run drain tube to its discharge point in accordance with plumbing codes. Pay special attention to codes for
air gaps and anti-siphon devices.
CAUTION: Never insert a drain line into a drain, sewer line, or trap. Always allow an air gap of 1-1/2” or twice the pipe
diameter, whichever is greater, between the drain line and the wastewater to prevent the possibility of sewage
being back-siphoned into the softener.

10. SAFETY BRINE TANK CONNECTION: Install the 3/8” O.D. polyethylene tube from the Refill Elbow to the Brine Safety Float valve in the
brine tank.
11. OVERFLOW LINE CONNECTION: An overflow drain line is recommended where a brine overflow could damage furnishings or the building
structure. Your unit is equipped with a brine tank safety float which greatly reduces the chance of an accidental brine overflow. In the event of
a malfunction, however, an overflow line connection will direct the “overflow” to the drain instead of spilling on the floor where it could cause
considerable damage. This fitting is an elbow on the side of the brine tank. Attach a length of 1/2” I.D. tubing to fitting and run to drain. Do not
elevate overflow line higher than 3” below bottom of overflow fitting. Do not connect this tube into the drain line of the control valve. Overflow
line must be a direct, separate line from overflow fitting to drain, sewer, or tub. Allow an air gap as per the drain line instructions.

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.

STARTUP INSTRUCTIONS
FLUSHING OF SYSTEM:
To flush the system of any debris and air after installation is complete, please perform the following steps:
1. Rotate bypass handles to the bypass mode (Fig. 2 on page 4) .
2. Turn on inlet water and check for leaks in the newly installed plumbing.
3. Fully open a cold water faucet, preferable at a laundry sink or bathtub without an aerator.
4. Wait two to three minutes or until water runs clear, then turn water off and follow start-up instructions.
Below is the name of each cycle as it appears on the screen with a description of the cycle position. The timing of each cycle will vary
depending on the unit size as set from the factory.
Name of Cycle Description
FILL BRINE TANK FILL
SOFTENING SOFT WATER BRINE MAKING
BACKWASH BACKWASH
REGENERANT DRAW DN (DOWN) BRINE DRAW AND SLOW RINSE
RINSE FAST RINSE
The system is now ready for filling with water and for testing.
1. With the softener in the bypass mode (Fig. 2 on page 4) and the control valve in normal operation where the display
shows either the time of day or the gallons remaining, manually add 3” of water to the brine tank.
NOTE: If too much water is put into the brine tank during softener start up, it could result in a “salty water”
complaint after the first regeneration.
During the first regeneration the unit will draw out the initial volume of brine/regenerant and refill it with the correct preset amount.
2. With the softener in bypass mode, press and hold the  button until the motor starts. Release button. The display reads “FILL”
and the remaining time in this step is counting down. Since the brine tank was already filled in Step 1, press  again and the
display will read SOFTENING 240 (During a full regeneration this will be a 4 hour period for salt to dissolve). Press  again to put
the valve into “BACKWASH.” Once valve has stopped in position, unplug the transformer so that the valve will not cycle to the next
position. Open the inlet handle of the bypass valve very slightly allowing water to fill the tank slowly in order to expel air.
CAUTION: If water flows too rapidly, there will be a loss of media to the drain.
3. When the water is flowing steadily to the drain without the presence of air, slowly open the inlet valve. Restore power and
momentarily press the  button to advance the control to the “BRINE” position.
4. With the bypass now in diagnostic mode (Fig. 3 on page 4), check to verify that water is being drawn from brine tank with no air leaks or
bubbles in the brine line. There should be a slow flow to the drain. Disconnect brine line from the safety float valve in the brine tank and
check for a vacuum. After proper confirmation, reconnect brine line, making sure to tighten securely.
5. Momentarily press  again until the display reads “RINSE.” There should be a rapid flow to the drain. Unplug transformer to keep
the valve in the “RINSE” position. Allow to run until steady, clear and without air. While the unit is rinsing, load the brine tank with
water softener salt (Refer to Brine Tank Maintenance and Salt Section). Restore power.
6. Place bypass valve in the normal operating mode (Fig. 1 on page 4) by opening the outlet bypass handle.
Press  and the unit will return to the service position with time of day being displayed.
7. CONDITIONING OF MEDIA:
To flush any remaining debris and air from the system again:
1. Full open a cold water faucet, preferably at a laundry sink or bathtub without an aerator.
2. Wait two to three minutes or until water runs clear, then turn water off.
3. Turn on hot water and check for air, then turn water off after air is discharged.
8. SANITIZING OF UNIT UPON INSTALLATION AND
At this time, it is advised to sanitize the softener:
1. Open brine tank and remove brine well cover.
2. Pour 1 oz. of household bleach into the brine well.
NOTE: Avoid pouring bleach directly onto the safety float components in the brine well.
3. Replace brine well cover.
Unit sanitizing will be complete when the first cycle is run and the bleach is flushed from the unit.
9. Check time of day. Start-up is now complete.

OPERATING DISPLAYS AND MAINTENANCE
1. GENERAL OPERATION: When the system is operating, one of five displays may be shown and will alternate with the installing dealer’s name
and phone number for future service. Pressing NEXT will alternate between the displays.
1. Time of Day Screen: Displays the current time of day, the day of the week, and flow rate.
2. Flow Rate Screen: Displays the current treated water flow rate through the system in Gallons Per Minute.
3. Capacity Remaining Screen: Displays the amount of gallons of treated water remaining until the system triggers a regeneration.
4. Days to a Regen Screen: Displays the number of days until the system triggers a regeneration. Based on the days override value.
5. Dealer Name Screen: Displays dealer specific name and phone number. This scrolling display will only appear if set by the dealer.
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. REGENERATION MODE: 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.
3. 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 and releasing 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.
Once a manual regeneration is initiated, the unit will enter the FILL position. This position allows water to enter the brine tank until it reaches the
proper level. Once this position is complete, you will notice a 240 minute (4 hours) SOFTENING position. This 4 hour window allows the salt to
dissolve and achieve proper brine strength. During these FILL and SOFTENING positions, you will have softened water available for use. Once the
unit advances to the BACKWASH position and subsequent positions thereafter (see Start Up Instructions for regeneration sequence), the unit will
deliver water, but it will be untreated.
IMPORTANT: With the Dry Salt Storage Feature, the brine tank will refill 4 hours before the actual regeneration occurs. You may
experience a small amount of noise for a short period of time at 10:00 p.m. (with factory settings) on the night that the
regeneration is to occur. This noise is only the brine tank filling and at no time during this process will you be without
treated water.

OPERATING DISPLAYS AND MAINTENANCE
4. 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. Wait five minutes for board to de-energize. Remove battery with a non-conductive/non-
metallic material. 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.
5. 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.
6. 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 (a small amount of 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.
