INSTALLATION
We recommend that you read the entire instructions before commencing the actual
installation. While we strongly recommend that a licensed plumber perform all installation
work, a mechanically-inclined homeowner can install an Iron Rival system. In all cases, it is
critical that the installation be done in accordance with these instructions and all applicable
plumbing and electrical codes. Be sure to obtain all required permits. If these instructions
and the applicable codes are in conflict, the relevant plumbing/electrical code shall be
followed. Equipment failure, personal injury, or property damage can result if this
equipment is not installed properly.
Step 1. –Pre-Installation Inspection
Inspect all of the components that you received with
your unit. You should have received the following:
1. Fleck 2510XST Control Valve
2. Treatment Tank
3. Upper Locking Stack Diffuser
4. Bypass
5. Riser tube and lower distributor
6. Bag or box of gravel
7. Bag or box of catalyst media (Birm or Filox)
8. Funnel
You may have also received a tank cover/jacket kit
if you ordered this option with your system.
Step 2. –Selecting an Installation Location
We recommend interior installation only. The
system cannot be allowed to freeze or severe system
damage could occur. The system should not be installed in direct sunlight as long-term exposure to
UV light could damage components of the system. Furthermore, direct sunlight could raise the
internal water temperature in the treatment tank and reduce backwash effectiveness. In most cases,
the Iron Rival should be located AFTER the expansion tank and sediment pre-filters (if applicable),
and BEFORE a water softener, carbon filters, and/or ultraviolet (UV) sterilizer (if applicable), and
the hot water heater. If possible, it is also generally desirable to place the Iron Rival AFTER the
plumbing branch off to your outdoor irrigation water.

5
Select a location for installation of your Iron Rival that is within close proximity to the main
incoming water lines of the home. The location should have a firm, level surface with sufficient
space for the treatment tank. Ensure that there will be sufficient space surrounding the unit to
facilitate maintenance.
You will also need access to a standard, non-switched, grounded 120volt (60 Hz) electrical outlet.
The Fleck 2510SXT control valve comes with a 5 foot long electrical cord. An extension cord may
be used to reach a suitable electrical outlet. If this option is used, ensure that the extension cord is
UL/CSA certified and of an appropriate wire gauge for the application.
You will also require a nearby floor drain or standpipe to discharge the drain water from the
backwash cycle (a drain standpipe for a washing machine, floor drain, or sump pump are excellent
drain options). We recommend that the drain line be connected to a minimum 1½" drain standpipe
or floor drain located ideally below the top of the head of your Iron Rival. If possible, the drain
should be no farther than 20 feet from the system.
Note: Never connect the drain line directly into a drain pipe. Allow an air gap between the drain
tubing and waste line to prevent the possibility of back-siphoning. We do not recommend use of a
check valve as it may become clogged with contaminants ejected from the system during backwash.
Step 3. –Prepare Treatment Tank
Two types of media are supplied with your Iron Rival system: washed gravel which forms the base
layer (underbedding) in your treatment tank, and specialized catalyst media (either Birm or Filox-R
depending on the model purchased), that promotes the rapid oxidation of the contaminants.
Before you start, gather the main treatment tank, the Fleck 2510SXT control valve, upper locking
stack diffuser, distributor and riser tube assembly (shipped inside the tank), funnel, and the bags or
boxes of gravel and catalyst media. Place the tank in the location where it will sit when the
installation is complete. Temporarily, remove the riser/tube distributor assembly from the treatment
tank. Hand tighten the Fleck 2510SXT control valve on the tank, and mark where the front of the
tank will be. Turn the tank so that the front of the tank is where you want it when it is full –once it
is full of media and water, it becomes very heavy and is hard to move!
Remove the controller and re-insert the distributor and riser tube assembly into the tank. The
distributor, which looks like a plastic screen, is pre-connected to the end of the long plastic riser
tube which extends from the bottom of the tank to the top of the tank where the control valve is
attached. At the bottom of the tank, there is a recess in the center of the tank to accept the
distributor to keep it aligned properly in the center of the tank. The riser tube has been pre-cut to
the correct height for you. When the distributor is correctly positioned, the top of the riser tube will
be almost perfectly flush with the top of the tank. If the tube is protruding above the tank, the
distributor tube is not nested correctly in the recess at the bottom of the tank.
Add enough water to the tank to cover the lower distributor with a minimum of 6 inches of water.
This will prevent damage to the lower distributor as gravel is loaded. Place the funnel into the tank
so that the riser tube is in the middle. Place tape over the open end of the riser tube. This will
prevent gravel or media from accidentally going down the tube during the following steps.

6
Take the bag/box of gravel and using a small scoop, add enough gravel to the tank through the
funnel to completely cover the distributor plus about 1 to 2 inches. Be sure to provide some
pressure on the riser tube while adding the gravel so as to ensure that the distributor does not shift
out of its recess. Ensure that you create an even layer of gravel across the bottom of the tank. A
rigid piece of thin wall tubing (conduit, copper pipe, etc.), approximately 1” longer than the tank
height works well as a leveling tool. As the tank fills, ensure that the riser tube remains centered in
the opening at the top of the tank.
Once this is complete, add the catalyst media in the same manner. Depending on the capacity of the
system, there will only be enough media to fill the tank to about 1/2 to 2/3 full. Use all of the
catalyst media provided. The treatment tank should never be filled to the top of the tank as the
remaining space, known as the “freeboard” is necessary for the media to have room to move during
the backwash cycle. Once the set-up is complete, the freeboard space will also contain a
pressurized pocket of air that provides aeration to begin the contaminant removal process.
Once you have finished adding the media to the tank, remove the tape from the distributor tube. Be
careful not to pull upwards on the riser tube while doing this as it is important that the distributor
remain in its recess at the bottom of the tank.
Fill the treatment tank with water up to within a couple of inches of the top of the tank. This will
allow the media to pre-soak, thereby preventing media loss during the initial backwash.
If you purchased an optional tank jacket kit, install it now.

7
DO NOT INITIATE A REGENERTION OF THIS SYSTEM FOR A
MINIMUM OF 24 HOURS AFTER ADDING THE WATER TO
ALLOW ADEQUATE PRE-SOAKING –BACKWASHING BEFORE
THE MEDIA IS SATURATED WILL CAUSE A LOSS OF MEDIA
AND POTENTIAL DAMAGE TO THE CONTROL VALVE.
Attach the upper locking stack diffuser onto the underside of the
control valve. Be sure to twist and lock into place.
Lubricate the tank O-ring seal. Note: Only use silicone lubricant.
The Fleck 2510SXT control valve (head) can now be secured to
the top of the tank. Before attaching the valve, check to make sure
that there is no debris such as gravel or media in the tank threads.
Screw the control valve onto the tank –make sure that the riser tube
inserts into the center hole in the upper stack diffuser and the control
valve as you screw down the valve. The control valve should be
hand-tightened (clockwise). Do not use the control valve's timer
assembly for leverage and do not use tools. A firm grasp with both
hands at the base of the valve will work. Do NOT use pipe cement
(“pipe dope”) or Teflon tape on the threads.
Step 4. –Turn off the Water & Electric Water Heaters
Turn off the household main water shutoff valve. Open all plumbing fixtures inside the home as
well as the outside faucets to drain as much water out of the plumbing system as possible.
If you have a conventional electric water heater or an on-demand (tankless) electric water heater,
we highly recommend that you turn off the electricity to the heater while installing any water
treatment equipment. Following completion of the entire installation, restore the water flow by
turning on the household main water valve and allow all air to be purged from the plumbing system
before turning the power back on to your water heater. Failure to follow this procedure could result
in serious, permanent damage to the heating elements in your water heater.
Step 5. –Prepare and Install Inlet and Outlet Plumbing Connections
Teflon®tape is the only sealant to be used on the bypass and drain fittings.
A bypass assembly is included with your system. Depending on the size of your Iron Rival, the
bypass will generally have ¾” or 1” NPT threaded fittings to connect to your main incoming and
outgoing water lines. You will need to purchase the appropriate NPT threaded fittings to connect to
the material and size of your main water line (inlet and outlet). Locate the inlet and outlet ports on
the back of the Fleck 2510SXT control valve. Note that the inlet and outlet are marked with arrows
indicating the correct direction of water flow. When you are looking at the back of the control
valve, the inlet is on the left and the outlet is on the right. A brass check valve is pre-installed on

8
the inlet side of the control valve. Check the
corresponding markings on the bypass to
ensure the correct direction of water flow and
insert the bypass (do not secure the clips yet).
The in and out arrows on the bypass should be
pointing the same direction as the in and out
arrows on the outside of the control valve.
BE VERY CAREFUL TO MAKE SURE
YOU PLUMB THE SYSTEM IN THE
RIGHT DIRECTION, OTHERWISE YOU
WILL LOOSE THE MEDIA OUT OF
THE TANK INTO YOUR HOUSE LINES.
Plumb your main incoming and outgoing water
lines using suitable pipe, fittings, elbows, etc. as
necessary to create a tidy, secure installation up
to the back of the bypass valve (including the
correct connection adapters to mate with the
threaded fittings on the bypass). Be sure to follow
all local plumbing codes. It is recommended that
downward loops (minimum 12”) be created in the
plumbing immediately before and after the Iron Rival. These loops serve to limit the migration of
air in the plumbing system in the event that some escapes the treatment system during regeneration.
VERY IMPORTANT:
If you wish to use copper piping and will be soldering the joints, DO NOT
apply heat near your control valve or bypass or serious internal damage to
these parts could occur. Always solder joints with these components
detached. If you are using copper adapters, it is recommended that you
solder a 5" piece of copper pipe into each of the connection adapters away
from the valve, then let them cool off before threading them onto the bypass
valve. After they cool off, apply Teflon tape or joint compound to the threads
and securely tighten them to the bypass valve.

9
Once you have prepared the plumbing up to the point of
the bypass following the above instructions, you can
connect your plumbing lines to the bypass valve. We
highly recommend that you remove the bypass before
making these connections as you may inadvertently
apply too much pressure on the valve while securing the
adapters, causing damage to the valve housing.
Once all plumbing to the bypass has been completed,
you can connect the bypass to the control valve. Push
the bypass onto the back of the valve and secure it using
the two stainless steel clips with screws located on the
back of the control valve. Do not overtighten -it is
normal for some “play” to exist when the bypass valve
is properly seated. This allows for minor misalignment
of the piping connections and relieves stress on the valve.
Place the bypass in the “bypass” position.
Step 6. –Drain Line Installation
During the backwash and regeneration cycle, your Iron Rival will send captured contaminants out
the drain port. This port needs to be connected to a suitable household drain ideally within 20 feet
of your treatment tank. A nearby floor drain, sump pump, or a standpipe for a washing machine is
an excellent option. We recommend that the drain line be connected to a minimum 1½" drain
standpipe or floor drain located ideally below the top of the head of your Iron Rival. You will need
to purchase suitable pipe or tubing for the drain line. The minimum diameter of the drain line for
residential applications should be ¾ inch. Commercial drain lines should be the same size as the
drain line flow control. While polyethylene tubing or copper pipe is suitable, we recommend rigid
PVC or CPVC pipe for the drain line. If you are using flexible tubing, be sure that there are no
“kinks” or “crimps” in the tubing after installation, that may cause a flow restriction. If used,
overhead drain lines are not to exceed a height of 5 feet above the control valve and should be not
more than 50 feet in length. Should an overhead drain line be utilized, it is recommended that the
drain line be increased in size (diameter), and that it not be fastened flush to the bottom of a floor
joist, to minimize noise transfer to the upstairs of a home during regeneration.
Locate the drain port on the back of your valve controller.
The drain line flow control with threaded fitting is
pre-attached to the control valve. To remove the drain line
flow control, pull up on the retaining clip to remove it and
then grasp the drain line flow control and pull outward.
Using an appropriate fitting, connect the drain line flow
control to your drain line tubing/pipe. Re-insert the drain
line flow control into the control valve and securely lock
into place with the retaining clip. Ensure that the drain line
is secured along its route to the drain. The drain line will be
under pressure when the regeneration / backwash cycle is

10
working, therefore make sure the drain line is well secured so it can not move around when
pressurized. If not adequately secured, the drain line could vibrate during backwash, particularly
during the initial purge of air from the top of the tank, causing excessive noise. If this is
experienced, use additional fixtures to better secure the drain line. The drain line should not be
exposed to freezing temperatures.
Note: Never connect the drain line directly into a drain. Allow an air-gap of a minimum of 1
inch (check local codes) between the drain line and waste line to prevent possibility of back-
siphon. Always follow local codes.
Step 7 –Control Valve Set-up
During cold weather, the installer should warm the control valve to room temperature before
operating. Note: All electrical connections must be done according to local codes.
Plug the control valve into a standard, grounded 120volt (60 Hz) electrical outlet. Be certain that
the outlet is uninterrupted and not controlled by a switch. The Fleck 2510SXT control valve comes
with a 5 foot long electrical cord. An extension cord may be used to reach a suitable electrical
outlet. Ensure that the extension cord is UL/CSA certified and of an appropriate wire gauge for the
application.
The digital display on the control valve will illuminate. Open the valve’s protective housing by
removing the screw located at the top right of the control valve and swinging the door open. This
will give you access to the buttons on the control valve. The digital display should be alternating
between the current time setting (which is probably incorrect), and the number “3” which indicates
the number of days remaining until the next regeneration cycle. You will also see the “service”
icon which appears as a small faucet in the bottom left corner of the display window.

11
NOTE: The Iron Rival control valve may need to reset to the home position when it is powered up.
If it does, the motor will run until it reaches service mode and time of day will return.
We will first set the time of day to the correct time. Press either the UP or DOWN button and hold
for a few seconds. The parameter display will read “TD” (Time of Day) and the “programming”
mode icon will appear (4 dots and a pencil). Use the UP and/or DOWN buttons to change the time
displayed to the correct time of day. Once the display shows the correct time, press the EXTRA
CYCLE button to save your changes.
Your Iron Rival has been pre-programmed to regenerate every 3 days and to perform the
regeneration process at 12:30am in the morning when it is very unlikely that water will be required
in the home. Unless advised by us, we do not recommend altering the frequency of regeneration.
However, you may edit the time that the regeneration process occurs if 12:30am is not ideal for you.
If you have a water softener or other automatic backwashing water treatment systems, make sure
that they are not set to regenerate at the same time. Follow the instructions under “User
Programming Mode” to change the regeneration time if desired.
Step 8 –Initial Start-up and Leak Testing
Ensure that the bypass is in the bypass position. Turn on the main water supply. Open a cold water
tap nearby and let the water run for a few minutes or until the system is free of foreign material
(usually solder) and air that may have resulted from the installation. Once clean, close the water
tap. Inspect your plumbing connections for leaks and repair any leaks found before proceeding.
Before putting the system into service, it is critical that the catalyst media soak for a minimum of 24
hours before you proceed with the remainder of the installation.
DO NOT INITIATE A REGENERTION OF THIS SYSTEM FOR A
MINIMUM OF 24 HOURS AFTER ADDING WATER TO THE
TREATMENT TANK TO ALLOW ADEQUATE PRE-SOAKING –
BACKWASHING BEFORE THE MEDIA IS SATURATED WILL
CAUSE A LOSS OF MEDIA AND POTENTIAL DAMAGE TO THE
CONTROL VALVE.
Once the catalyst media has been adequately pre-soaked for 24 hours:
WITH THE BYPASS STILL IN THE BYPASS POSITION, press the EXTRA CYCLE button and
hold it down for about 5 seconds until you hear the valve change positions and the parameter
display changes to read “BW” (Backwash) and the time starts counting down. Once the motor has
stopped moving (no more noise), press the EXTRA CYCLE button again to advance to the next

12
stage of the regeneration cycle –“BD” (Brine Draw / Air Draw). Once the valve has stopped
moving, press the EXTRA CYCLE button again to advance to the next stage of the regeneration
cycle –“RR” (Rapid Rinse).
Without delay, immediately begin to slowly open the
bypass to the service position, allowing water to flow
into the system. Water and air will begin to flow to
the drain line and will continue for 1 minute. At the
end of this time, the valve will re-position and the filter
will return to normal service mode. Inspect your drain
line plumbing connections and repair any leaks
immediately before proceeding. If the plumbing pipe
rattled or vibrated during this process causing excessive
noise, use additional fasteners to better secure the drain line.
Slowly open a cold filtered water tap nearby and let the water run for a few minutes until the system
is purged of all air that may have resulted from the installation. Repeat for other faucets in the
home starting at the highest elevation and working down to the lowest point until all air is purged.
The initial flow of water may be slightly discolored. This is normal and will go away quickly.
It is now safe to turn the electricity back on to your water heater.
Press the EXTRA CYCLE button and hold it down for about 5 seconds to initiate a complete
regeneration cycle.
DO NOT INITIATE A REGENERTION OF THIS SYSTEM FOR A
MINIMUM OF 24 HOURS AFTER ADDING WATER TO THE
TREATMENT TANK TO ALLOW ADEQUATE PRE-SOAKING –
BACKWASHING BEFORE THE MEDIA IS SATURATED WILL
CAUSE A LOSS OF MEDIA AND POTENTIAL DAMAGE TO THE
CONTROL VALVE.
The control valve will perform a standard regeneration automatically, including a 14 minute
backwash, 40 minute air draw, and 1 minute rapid rinse (your settings may differ due to
programming selected by our technicians for your specific water conditions). Once this process is
complete, your set-up and installation is done!
Congratulations! Your system is now ready to provide treated water to your home!
If you have a tank-style water heater, it will still contain untreated water for a few days, but your
cold water lines will begin dispensing treated water right away.

13
REGENERATION
The regeneration process is automatically engaged and controlled by your control valve. Your
system was pre-programmed at the factory based on your water conditions. In most cases, your
system will be programmed at the factory to regenerate every 3 days at 12:30am. Models with
Filox-R media will generally be set to regenerate daily.
There are 3 steps to the regeneration process:
Step 1: Backwash: factory pre-set for 14 minutes (parameter display code BW)
Step 2: Air Draw: factory pre-set for 40 minutes (parameter display code BD)
Step 3: Rapid Rinse: factory pre-set for 1 minute (parameter display code RR)
Unless directed by a water treatment professional familiar with this system, we do not recommend
that you alter the duration of any of the regeneration cycles. If necessary, these parameters can be
adjusted thru the Master Programming Mode (see below).
During each step of regeneration, the digital display on the control valve will indicate the cycle
currently underway and the amount of time remaining in that cycle.
There may be instances where more frequent regeneration is required. For instance, if your water
consumption increases considerably due to additional guests at your home, or if your feed water
conditions temporarily worsen, you may want to perform a manual regeneration. You an choose to
initiate a manual regeneration immediately or the next time the regeneration time of day is reached:
To initiate a manual regeneration the next time the regeneration time of day is reached:
Press the EXTRA CYCLE button once. The “service” icon will begin to flash indicating that a
regeneration is scheduled next time the regeneration time of day is reached.
To cancel a queued regeneration, press the EXTRA CYCLE button.
To initiate an immediate manual regeneration:
Press the EXTRA CYCLE button and hold it down for 5 seconds until the regeneration process
begins.
Skip through regeneration steps:
There may be times that it may be desirable to skip through regeneration steps without allowing
them to fully complete. This would be most typical during servicing. When a cycle engages,
always wait until the motor has stopped before skipping to the next cycle. You can hear the valve
motor while it is repositioning the valve at the beginning of each cycle. During the regeneration
process, you can advance to the next step by pressing the EXTRA CYCLE button.
The control valve will continue to keep time and the passage of days for a minimum of 48 hours in
the event of power failure.

14
CHANGING TIME OF DAY
During regular service mode, the digital display will alternate between the current time of day and
the number of days until the next scheduled regeneration. For proper operation, it is important that
the valve display the correct time of day. To change the time of day, press either the UP or DOWN
button and hold for a few seconds. The “programming” icon will appear. Use the UP and/or
DOWN buttons to change the time displayed to the correct time of day. Once the display shows the
correct time, press the EXTRA CYCLE button to save your changes.
USER PROGRAMMING MODE
The User Programming Mode allows you to set the frequency of regeneration and the time of day
that regeneration will take place.
To enter the User Programming Mode, press the UP and DOWN arrows at the same time and hold
for 5 seconds until the “programming” mode icon appears. If the current time display is 12:01PM,
you cannot enter the User Programming Mode –simply wait a minute before attempting.
The display will first show the DAYS OVERRIDE (parameter display code DO). This is the
setting that determines the frequency of regenerations (measured in days). It is generally
recommend that the system regenerate at least every 3 days for models using Birm media and daily
for models using Filox-R media. Failure to do so, could result in decline in contaminant removal
performance and loss of water pressure due to media clogging.
To change the setting, use the UP and DOWN buttons. Press the EXTRA CYCLE button when
done. If you do not want to change the current setting, simply press the EXTRA CYCLE button to
skip to the next step.
The display will now show the REGENERATION TIME (parameter display code RT). This is
the setting that determines the time of day that the automatic regeneration will start. It is strongly
recommended that regenerations be set to occur at night when water will not be in use. If you have
other water treatment equipment that backwashes (such as a water softener), make sure that your
Iron Rival is not set to backwash at the same time.

15
To change the setting, use the UP and DOWN buttons. Press the EXTRA CYCLE button when
done. If you do not want to change the current setting, simply press the EXTRA CYCLE button
return to service mode.
The system should now return to normal service mode. The unit will also return to normal
operation after 5 seconds if no buttons are pressed.
MASTER PROGRAMMING MODE
The Master Programming Mode is designed for professional use only. Unless directed by a water
treatment professional familiar with the system, it is not recommended that any of the Master
Programming Mode settings be modified.
To enter the Master Programming Mode, first set the time of day to 12:01PM. With the time
display showing 12:01PM, enter the Master Programming Mode, by pressing the UP and DOWN
arrows at the same time and holding for 5 seconds until the “programming” mode icon appears.
In this mode, you can adjust a parameter setting by using the UP and DOWN buttons. To save your
changes and/or to skip to the next parameter, press the EXTRA CYCLE button. Press the
EXTRA CYCLE button at the last parameter to save all settings and return to normal operation. The
control will automatically disregard any programming changes and return to normal operation if it
is left in Master Programming Mode for 5 minutes without any keypad input. The following
settings are the factory default settings for the Iron Rival:
Parameter Parameter Code Option Code Option Description

RESETS
WARNING: USE OF THE RESET FUNCTIONS IS NOT RECOMMENDED EXCEPT UNDER THE
GUIDANCE OF A WATER TREATMENT PROFESSIONAL FAMILIAR WITH THIS EQUIPMENT.
Soft Reset: Press and hold the EXTRA CYCLE and DOWN buttons for 25 seconds while in
normal Service mode. This resets all parameters to the system default values except days since
regeneration in the time clock system.
Master Reset: Hold the Extra Cycle button while powering up the unit. This resets all of the
parameters in the unit. Check and verify the choices selected in Master Programming Mode.
CONTROL OPERATION DURING A POWER
FAILURE
The 2510SXT valve/controller includes integral power backup. In the event of power failure, the
control shifts into a power-saving mode. The control stops monitoring water usage, and the display
and motor shut down, but it continues to keep track of the time and day for a minimum of 48 hours.
The system configuration settings are stored in a non-volatile memory and are stored indefinitely
with or without line power. The Time of Day flashes when there has been a power failure. Press any
button to stop the Time of Day from flashing.
If power fails while the unit is in regeneration, the control will save the current valve position
before it shuts down. When power is restored, the control will resume the regeneration cycle from
the point where power failed. Note that if power fails during a regeneration cycle, the valve will
remain in it’s current position until power is restored. The drain line plumbing configuration should
include all required safety components to prevent overflows resulting from a power failure during
regeneration.
The control will not start a new regeneration cycle without line power. If the valve misses a
scheduled regeneration due to a power failure, it will queue a regeneration. Once power is restored,
the control will initiate a regeneration cycle the next time that the Time of Day equals the
programmed regeneration time. Typically, this means that the valve will regenerate one day after it
was originally scheduled.

MAINTENANCE & TROUBLESHOOTING
WARNING: The controller MUST be depressurized before removing any quick connection
clips for servicing. The connector should be pushed toward the control while removing clips.
Service Recommendations
Your Iron Rival is built for long term operation with limited maintenance. In harsh conditions,
particular where water is acidic, highly contaminated, or where excessive levels of hydrogen sulfide
are present, the seals and spacers and piston assembly may require periodic servicing or
replacement. A service professional should be contacted for this maintenance.
Birm media will generally last many years. In ideal conditions, it can last indefinitely, however, a
more typical life is 5 to 7 years. The Birm media can be replaced if it becomes depleted. Filox-R
media will generally last in excess of 10 years as long as it is adequately backwashed to remove
trapped contaminants. Inadequate backwash duration or flow rates could cause media clogging
which could require the replacement of the media to restore flow and pressure performance.
Troubleshooting
PROBLEM CAUSE CORRECTION
1. Iron Rival valve fails to regenerate A. Electrical service to unit has been
interrupted.
B. Timer is defective.
A. Assure permanent electrical
service (check fuse, plug, pull chain
or switch).
B. Replace timer.
2. Loss of water pressure. A. Iron buildup in line to water
conditioner.
B. Iron buildup in water conditioner.
C. Inlet of control plugged due to
foreign material broken loose from
pipe by recent work done on
plumbing system.
A. Clean line to water conditioner.
B. Clean control and add mineral
cleaner to mineral bed. Increase
frequency of regeneration and/or
backwash time.
C. Remove pistons and clean control.
3. Loss of mineral through drain line. A. Drain line flow control too large. A. Check to ensure drain line flow
control is sized properly for your
mineral tank.
4. Iron in treated water. A. Bypass valve is open.
B. Unit does not draw air during
regeneration.
C. Injector screen plugged.
D. Tank does not fully flush with air
during regeneration.
E. Water usage depletes oxidizer
capacity before regeneration.
F. Leak at distributor tube.
G. Internal valve leak
A. Close bypass valve.
B. Check the air inlet check valve.
Clean or replace as needed.
C. Clean injector screen.
D. Verify the draw time setting and
adjust as needed.
E. Adjust regeneration frequency to
meet demand.
F. Make sure distributor tube is not
cracked. Check O-ring and tube pilot.
G. Replace seals and spacers and/or
piston.

ERROR CODES
Code Error Cause Reset & recovery
0Cam Sense
Error The valve drive took longer than 6 minutes to advance to
the next regeneration position.
Unplug the unit and examine the control valve. Verify
that all cam switches are connected to the circuit
board and functioning properly. Verify that the motor
and drive train components are in good condition
and assembled properly. Check the valve and verify
that the piston travels freely. Replace/reassemble
the various components as necessary. Plug the unit
back in and observe its behavior. The unit should cycle
to the next valve position and stop. If the error re-
occurs, unplug the unit and contact technical support.
1Cycle Step
Error The control experienced an unexpected cycle input. Unplug the unit and examine the control valve. Verify that all cam switches are connected to the
circuit board and functioning properly. Enter Master
Programming mode and verify that the valve type
and system type are set correctly with regard to the
unit itself. Step the unit through a manual regeneration
and verify that it functions correctly. If the error re-
occurs unplug the unit and contact technical support.
2Regen Failure The system has not
regenerated for more than 99
days.
Perform a Manual Regeneration to reset the
error code. Enter Master Programming mode and
verify that the unit is configured properly. As
appropriate for the valve configuration, check that the
correct system capacity has been selected, and that the
day override is set properly. Correct the
settings as necessary.
3Memory Error Control board memory failure. Perform a Master Reset and reconfigure the system
via Master Programming mode. After reconfiguring
the system, set the valve through a manual
regeneration. If the error re-occurs, unplug the unit and
contact technical support.
