SECTION 1: BEFORE INSTALLATION
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Read and follow Use instructions before installation and use of this water treatment system.
• Installation and use MUST comply with existing state or local plumbing codes.
ELECTRICAL
There are no user-serviceable parts in the AC adapter, motor, or controller. In the event of a failure, these should be replaced.
1) All electrical connections must be completed according to local codes.
2) Use only the power AC adapter that is supplied.
3) The power outlet must be grounded.
4) To disconnect power, unplug the AC adapter from its power source.
MECHANICAL
1) Do not use petroleum based lubricants such as Vaseline, oils, or hydrocarbon based lubricants. Use only 100% silicone lubricants.
2) All plastic connections should be hand tightened. Thread tape may be used on connections that do not use an o-ring seal. Do not use pliers or pipe wrenches.
3) All plumbing must be completed according to local codes.
4) Soldering near the drain line should be done before connecting the drain line to the valve. Excessive heat will cause interior damage to the valve.
5) Observe drain line requirements.
6) Do not use lead-based solder for sweat solder connections.
7) The drain line must be a minimum of 1/2 inch diameter. Use 3/4 inch pipe if the backwash flow rate is greater than 7 gpm (26.5 lpm) or the pipe length is
greater than 20 ft (6 m).
8) Do not support the weight of the system on the control valve fittings, plumbing or the bypass.
9) It is not recommended to use sealants on the threads. Use thread tap on the threads of the 1 inch NPT elbow, the drain line connections, and other NPT
threads.
1-1

GENERAL
1) Observe all warning and caution statements that appear in this manual.
2) Keep the media tank in the upright position. Do not turn upside down or drop. Turning the tank upside down will cause media to enter the valve.
3) Operating temperature is between 34°F (1°C) and 110°F (43.3°C).
4) Rated water pressure range is 20 - 100 psi.
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Installation and use MUST comply with existing state or local plumbing codes.
• Do not install on hot water supply lines. The maximum operating water temperature of this filter system is 110°F (43.3°C).
• Do not install if water pressure exceeds 100 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact a plumb-
ing professional if you are uncertain how to check your water pressure.
5) Use only regenerant salts designed for water softening.
IMPORTANT NOTE
SODIUM INFORMATION: Water softeners using sodium chloride for regeneration add sodium to the water. Persons who are on sodium restricted diets
should consider the added as part of their overall sodium intake.
6) Follow state and local codes for water testing.
WARNING
To reduce the risk associated with ingestion of contaminants:
• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
7) When installing the water connections (bypass or manifold) connect to the plumbing system first. Allow heated parts to cool and cemented parts to be set
before installing any plastic parts. Do not get primer or solvent on o-rings, nuts or the valve.
IMPORTANT NOTE
If sediment is present, the installation of a sediment pre-filter is recommended. Even if sediment is not currently present or at a level high enough to be objection-
able, a pre-filter can increase the efficiency of the softener and reduce the amount of maintenance required.
LOCATION SELECTION
Location of a water treatment system is important. The following conditions are required:
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Do not install on hot water supply lines. The maximum operating water temperature of this filter system is 110°F (43.3°C).
• Do not install if water pressure exceeds 100 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact a plumb-
ing professional if you are uncertain how to check your water pressure.
• Do not install where water hammer conditions may occur. If water hammer conditions exist you must install a water hammer arrester. Contact a plumbing
professional if you are uncertain how to check for this condition.
• Mount system in such a position as to prevent it from being struck by other items used in the area of installation.
• Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention.
• Install on a flat/level surface. It is also advisable to sweep the floor to eliminate objects that could pierce the brine tank.
1) Level platform or floor.

SECTION 2: INSTALLATION
WATER LINE CONNECTION
A bypass valve system should be installed on all water conditioning systems. Bypass valves isolate the conditioner from the water system and allow unconditioned
water to be used. Service or routine maintenance procedures may also require that the system is bypassed.
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Installation and use MUST comply with existing state or local plumbing codes.
• Do not use a torch or other high temperature sources near filter system, cartridges, plastic fittings or plastic plumbing.
• On plastic fittings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic.
• Take care when using pliers or pipe wrenches to tighten plastic fittings, as damage may occur if over tightening occurs.
To reduce the risk associated with property damage due to plugged water lines:
• Pay particular attention to correct orientation of control valve. Water flow should match arrow on control valve. The Inlet and Outlet of other water treatment
equipment products will vary depending on the control valve brand used.
DRAIN LINE CONNECTION
NOTE: Standard commercial practices are expressed here. Local codes may require changes to the following suggestions. Check with local authorities before
installing a system.
1) The unit should be above and not more than 20 ft (6.1 m) from the drain. Use an appropriate adapter fitting to connect
1/2 inch (1.3 cm) plastic tubing to the drain line connection of the control valve.
2) If the backwash flow rate exceeds 5 gpm (22.7 lpm) or if the unit is located 20 - 40 ft (6.1 - 12.2 m) from drain, use
3/4 inch (1.9 cm) tubing. Use appropriate fittings to connect the 3/4 inch tubing to the 3/4 inch NPT drain connection
on valve.
3) The drain line may be elevated up to 6 ft (1.8 m) providing the run does not exceed 15 ft (4.6 m) and water pressure
at the conditioner is not less than 40 psi. Elevation can increase by 2 ft (61 cm) for each additional 10 psi of water
pressure at the drain connector.
4) Where the drain line is elevated but empties into a drain below the level of the control valve, form a 7 inch (18 cm)
loop at the far end of the line so that the bottom of the loop is level with the drain line connection. This will provide
an adequate siphon trap. Where the drain empties into an overhead sewer, a sink-type trap must be used. Secure
the end of the drain line to prevent it from moving.
IMPORTANT NOTE
Never insert drain line directly into a drain, sewer line or trap. Always allow an air gap between the drain line and the wastewater to prevent the possibility of
sewage being back-siphoned into the conditioner.
In the event of a malfunction, the BRINE TANK OVERFLOW will direct “overflow” to the drain instead of spilling on the floor. This fitting is located on the side of the
brine tank.
Do not elevate overflow line higher than overflow fitting.
Do not tie into drain line of control unit. Overflow line must be a direct, separate line from overflow fitting to drain, sewer or tub. Allow an air gap as per drain line
instructions.
Drain Line Connection

BRINE LINE CONNECTION
The brine line to the brine tank connects to the valve. Make the connections and tighten. Be sure that the brine line is secure
and free from air leak. Even a small leak may cause the brine line to drain out, and the conditioner will not draw brine from
the tank. This may also introduce air into the valve causing problems with valve operation.
ELECTRICAL CONNECTION
All AWS controllers operate on 12-volt alternating current power supply. This requires use of the supplied AC adapter.
AC ADAPTERS
Make sure power source matches the rating printed on the AC adapter.
IMPORTANT NOTE
The power source should be constant. Be certain the AC adapter is not on a switched outlet. Power interruptions longer than 8 hours may cause the controller
to lose the time and day settings. When power is restored, the day and time settings must then be reentered.
CAMSHAFT
The front end of the camshaft has an indicator cup. The cup has slots in the outer periphery and numbers on the inside face.
The numbers can be seen with the cover off, from the front over the top of the controller. The number at the top indicates
which regeneration cycle is currently in progress.
CAMSHAFT FRONT END
The corresponding slot for the number is positioned at the optical sensor which is approximately 90 degrees out of phase.
Regeneration Cycle Indicators
C0 = Treated Water - normal operation mode
C1 = Backwash Cycle
C2 = Brine Draw Cycle
C3 = Slow Rinse Cycle
C4 = System Pause
C5 = Fast Rinse Cycle 1
C6 = Backwash Cycle 2
C7 = Fast Rinse Cycle 2
C8 = Brine Refill
POWER LOSS MEMORY RETENTION
The AWS series controllers feature battery-free time and date retention during the loss of power. This is designed to last a minimum of 8 hours depending on the
installation. The controller will continue to keep time and day in dynamic memory while there is no AC power.
The controller will not track water usage on volumetric demand controls in the event of a power failure.
All programmed parameters are stored in the static memory and will not be lost in the event of a power failure. These settings are maintained separately from the
time and day settings.
MOTOR
The controller uses a standard 12-volt AC motor that works with either 50 Hz or 60 Hz. The same motor is used worldwide and does not need to be changed for
different power conditions.
Information entered or calculated by the controller is stored in two different ways:
A static memory will store:
Media volume
Regenerant setting
Time of regeneration
Days between regeneration
2-2

2-3
A dynamic memory with 8 hour retention will store:
Current day of week
Running clock
IMPORTANT NOTE
Water flow to the valve can be turned on or bypassed when the controller is powered up for the first time.
VARIABLE RESERVE FUNCTION
The AWS metered-demand volumetric controllers are designed to have a variable reserve feature. This feature automatically adjusts the reserve to the end-user’s
water usage schedule.
A variable reserve saves salt and water by only regenerating when absolutely necessary, and ensures enough soft water for typical high-water usage days.
Each day of regeneration the controller reviews the last four weeks of water usage for the same day of the week to determine if the remaining capacity is adequate
for the next day of the week. If not, it will initiate an automatic regeneration.
DISPLAY ICONS
IMPORTANT NOTE
In normal operation and during programming, only a few of the icons will actually be displayed.
1) Days of the week. The flag immediately below the day will appear when that day has been programmed as a day the system should regenerated (used with
7-day timer programming).
2) See #3
3) This cursor is displayed when the days between regeneration are being programmed (used with .5 to 99 day regeneration programming).
4) One of these cursors will be displayed to indicate which day will be programmed into the controller
5) “PM” indicates that the time displayed is between 12:00 noon and 12:00 midnight (there is no AM indicator). PM indicator is not used if clock mode is set to
24-hour.

To cancel a regeneration (either manual or automatic):
• Press and hold the SET button and UP buttons simultaneously and hold until the hourglass icon starts flashing (approximately 5 seconds).
• The regeneration is cancelled.
• The camshaft rotates to the treated water position (may take up to 2 min.)
• Hourglass flashes while motor runs.
If a second regeneration was programmed (display shows a 2X by the regeneration icon) both regenerations must be cancelled separately.
IMPORTANT NOTES
• Cancelling a regeneration may cause undesirable or salty water to go into the plumbing. Only use this function when absolutely necessary.
• If the regeneration cycle is cancelled after the brine draw cycle (C2), check the water level in the brine tank. It must be refilled to the proper level.

The controller can be manually instructed to perform a regeneration. There are two (2) choices: The controller will perform a delayed regeneration at the next time
of regeneration (ex. 2:00 AM that night), or regenerate immediately.
For a delayed regeneration (at the next set time of regeneration):
• Push the REGEN button once. The recycle symbol will be flashing on the display. Push the REGEN button again to cancel.
For an immediate regeneration:
• Push and hold the REGEN button for five (5) seconds. The display will show the regeneration symbol. The camshaft will start rotating to cycle C1.
For an immediate, double regeneration:
• After an immediate manual regeneration has begun, and the camshaft has rotated to cycle C1, you can initiate a second immediate manual regeneration.
• Press and hold the REGEN button for 5 seconds once the camshaft has begun cycle C1.
• The display will show a x2 icon indication that a second manual regeneration will occur after the current regeneration is completed.

2-7
STARTUP
IMPORTANT NOTE
The control valve can be started-up even if power is not yet available to the controller. The valve must be connected to water supply. The motor can be unmounted
from the valve, and the camshaft can be indexed manually counterclockwise by hand. This will allow the tank to be filled and allows regenerant draw to be tested.
See Motor Removal in Maintenance and Service of this manual for further instructions.
1) Remove the cover from the valve. Removing the cover will allow you to see that the camshaft is turning, and in which cycle the camshaft is currently posi-
tioned.
2) With the supply water for the system still turned off, position the bypass valve to the “not in bypass” (normal operation) position.
3) Hold the REGEN button on the controller down for 5 seconds. This will initiate a manual regeneration.
The controller will indicate that the motor is turning the camshaft to the cycle C1 (Backwash) position by flashing an hourglass. The controller will display the total
regen time remaining.
If you press and hold the SET button, the controller will indicate the time remaining in the current cycle.
4) Fill the media tank with water.
A) While the controller is in cycle C1 (Backwash), open the water supply valve very slowly to approximately the 1/4 open position
IMPORTANT NOTE
If opened too rapidly or too far, media may be lost out of the tank into the valve or the plumbing. In the 1/4 open position, you should hear air slowly escaping
from the valve drain line.
B) When all of the air has been purged from the media tank (water begins to flow steadily from the drain line), open the main supply valve all of the way.
This will purge the final air from the tank.
C) Allow water to run to drain until the water runs clear from the drain line. This purges any refuse from the media bed.
D) Turn off the water supply and let the system stand for about five minutes. This will allow for any air trapped to escape from the tank.
5) Add water to the brine tank (initial fill).
A) With a bucket or hose, add approximately 2 gallons (8 liters) of water to the regenerant tank.
If the tank has a salt platform in the bottom of the tank, add water until the water level is approximately 1 inch (25 mm) above the platform.
IMPORTANT NOTE
We recommend that you do not put salt into the tank until after the control valve has been put into operation. With no salt in the tank, it is much easier to view
water flow and motion in the tank.

6) Engage the refill cycle to prime the line between the brine tank and the valve.
A) Slowly open the main water supply valve again, to the fully open position. Be sure not to open too rapidly as that would push the media out of the media
tank.
B) Advance the controller to the Refill Position. From cycle C1 (Backwash), press and hold the SET button. This will display the current cycle.
While pressing the SET button, press the UP arrow to advance to the next cycle. Continue to advance through each cycle until you have reached cycle C8 (Refill).

2-8
IMPORTANT NOTE
As you advance through each cycle there will be a slight delay before you can advance to the next cycle. The hourglass icon will light while the camshaft is index-
ing. There may be a pause at cycle C4 (System Pause). This cycle allows the water/air pressure to equalize on each side of the valve discs before moving on.
The hourglass will not be visible indicating that the system is paused.
C) With the water supply completely open, when you arrive at cycle C8 (Refill), the controller will direct water down through the line to the brine tank. Let
the water flow through the line until all air bubbles have been purged from the line.
D) Do not let the water flow down the line to the tank for more than one to two minutes, or the tank may overfill.
E) Once the air is purged from the line, press the SET button and the UP button simultaneously to advance to cycle C0 (Treated Water) position.
7) Draw water from the brine tank.
Action Key Duration Display

A) From the treated water position (cycle C0), advance the valve to the brine draw position. Hold the REGEN button down for 5 seconds.
The controller will begin a manual regen, and advance the control valve to the cycle C1 (Backwash). Press the SET and UP button to advance to cycle C2
(Draw).
B) With the controller in this position, check to see that the water in the brine tank is being drawn out of the tank. The water level in the tank should recede
very slowly.
C) Observe the water being drawn from the tank for at least three minutes. If the water level does not recede, or goes up, reference the Troubleshooting
section.
8) If the water level is receding from the tank you can then advance the controller back to the treated water (C0) position by pressing SET and the UP buttons
simultaneously to advance the controller to the C0 position.
9) Before loading salt add enough water back to the brine tank to cover the salt grid by approximately one (1) inch. Then add initial salt fill to brine tank, and one
cup full of unscented laundry bleach to the brine well.
10) Put softener through a complete regeneration - to sanitize the system before use (refer to previous section for instructions on manual regeneration).
11) Finally, after the regeneration is complete, turn on a faucet plumbed after the water conditioner. Run the faucet until the water runs clear.
Installation is now complete, and your water softener is now ready for service!

THINGS YOU MIGHT NEED TO KNOW
• When the controller is first plugged in, it may display a flashing hourglass and the message Err 3, this means that the controller is rotating to the home position.
If the Err 2 is displayed, check that the incoming power frequency matches the controller. See the Troubleshooting section of this manual.
• The preset default time of regeneration is 2:00 AM. If you want to change it, see the Level II Programming section.
• The controller can be programmed to regenerate on specific days of the week. See Level II Programming section.
• If electrical power is not available, the camshaft can be rotated to the left by hand if the motor is removed. See Motor Removal in the Maintenance section.
• The controller sends commands to the motor for camshaft movement. However, water pressure/flow are required during the regeneration cycle for backwash,
purge and refill, and brine draw to actually take place.
• Make sure control power source is plugged in. The transformer should be connected to a non-switched power source.
PROGRAMMING
The controller is designed to operate by only setting the time of day and the day of the week. The remaining settings have been set at the factory. These default
settings will work for most applications.
The controller menu has three levels:
Level I Basic — This level is easily accessed by the user. The settings can be changed and saved as long as they are not locked.
Level II Professional — This level allows the installer to lock settings. The locked settings are viewable in the basic level but cannot be changed.
History Level — The operation history and the program are viewable. This information is used to troubleshoot and maintain the system.
BASIC PROGRAMMING
IMPORTANT NOTES
If a button is not pushed for thirty seconds, the controller returns to normal operation mode. Pushing the regenerate button immediately returns the controller to
normal operation.
Any setting that is a time display will not show “AM” for times between 12:00 midnight and 12:00 noon. “PM” is displayed to the right of the time for times
between 12:00 noon and 12:00 midnight. When using the 24 hour clock “PM” is not displayed.

• Calendar override
The controller can be programmed to regenerate automatically from a 1/2 day to a 99 day frequency.
The 1/2 day regeneration mode will regenerate at the “time of regeneration,” as well as 12 hours opposite from that time. For example, the controller will regenerate
at 2:00 AM and at 2:00 PM on the same day.
The default setting is 12 days. To change, push SET when this setting is displayed. Use the arrow buttons to increase/decrease. Push SET to enter the selection.
IMPORTANT NOTES
Setting days between regeneration to zero will cause the system to not regenerate. This setting is used for selecting regeneration on specific days or to use with
a remote regeneration input. See below.
Regeneration on specific day is used to provide regeneration when water demands are not steady. Example: If the weekdays have low usage and the weekend
is high, then regeneration every three days will not meet the requirements.
• Amount of salt used per regeneration
The controllers are setup to automatically calculate the capacity of the system by multiplying the resin/media volume that was entered earlier into the controller, with
the salt amount entered by the dealer/installer. This eliminates the need for salting efficiency tables.
The default setting is L (Low Salt).
To enable the most simple programming possible, the dealer/installer has three salt amount options to choose from. These are set up to give the installation the
maximum performance based on the inputs by the dealer/installer. The three salt options are:
High Salt — This setting gives the installation the highest capacity possible for that resin volume. This is a great setting for applications with very high hardness,
many occupants or for applications where the dealer wants to provide that the application supplies soft water. This setting may tend to use less water over the
course of a year, because it generally needs to be regenerated less often. This setting is displayed as an “H”.
Standard Salt — This setting fits most applications around the world. It gives you an efficient use of salt, while maintaining a large enough capacity to regenerate
every three days for most applications. This setting is displayed as an “S”.
Low Salt — This setting is provided to give your installation the maximum efficiency of salt usage, as measured in grains of hardness softened per pound of salt used
(grains of CaCo3 reduced per pound of salt used). This setting is useful for markets where highly efficient conditioners are expected or required by the consumers
or law. This setting is displayed as an “L”.
IMPORTANT NOTE
SODIUM INFORMATION: Water softeners using sodium chloride for regeneration add sodium to the water. Persons who are on sodium restricted diets
should consider the added as part of their overall sodium intake.

The following tables show the estimated salt amount for each setting, as well as the estimated capacity of that salt setting for each resin amount.

L = Low salt, approximately 3.3 lbs. per cu. ft. of media
S = Standard salt, approximately 9 lbs. per cu. ft. of media
H = High salt, approximately 15 lbs. per cu. ft. of media
To program the salt amount, press the SET button to enter the change mode. The L default will begin to flash. Use the UP and DOWN arrow keys to scroll through
the three settings. Press the SET button to enter the amount.
• Capacity
The controller is designed to estimate capacity of the system by multiplying the initial resin/media volume by the regenerant amount programmed in under “Amount
of regenerant used per regeneration.”
An estimated total system capacity is displayed in kilograins (kilograms CaCO3) that could be removed by the fully regenerated media bed. This value is derived by
standard water treatment industry norms. The system capacity is displayed merely for the installers reference when determining regeneration frequency.
NOTE: Capacity is the result of the amount of media in the tank and the salt setting. The default capacity will be changed by selecting a different salt setting.
• Hardness setting
The hardness setting is set in grains per gallon (CaCO3). The hardness is divided into the total capacity setting, giving a total volume of water that can be conditioned
before a regeneration is needed. To set, press SET when P8 is displayed, and use the UP or DOWN buttons to increment. Press SET again to accept the setting.
HISTORY LEVEL
This level displays settings and usage information that can be used to diagnose and troubleshoot the system.

When in history values mode a small “H” will be displayed in the lower left corner of the display. Next to the “H” will be the number that applies to the history
value.
H0 — System Resin Volume Setting
The history value H0 displays the initial resin volume setting (programmed when the system was first set up). If the value is incorrect and needs to be reset, press
and hold the SET button for five seconds to reset the controller.
IMPORTANT NOTE
Resetting the resin volume resets the entire controller back to the factory default. Only use if absolutely necessary. The control will need to be completely re-
programmed.

SECTION 4: SERVICE INSTRUCTIONS & MAINTENANCE
VALVE SERVICE
COVER
The cover provides protection for the controller, wiring, and other components. This cover will be removed for most service and maintenance.
When installed, the cover provides NEMA 3 water protection. This protects from falling water up to 30 degrees from vertical.
To remove cover:
1) Grasp side edges toward rear of the valve.
2) Pull outwards until the slots in the cover clears the projections on the top plate.
3) Lift up on the rear and pull forward to clear the control module.
To install cover:
1) Position cover to be low in front and under the bottom edge of the control module.
2) The cover will hook on the bottom of the controller and drop down over the camshaft.
3) To finish, grasp the side edges and pull outward to clear the projections on the top plate.
4) Drop down until the cover snaps in place.
ELECTRONIC CONTROL MODULE
The purpose of the electronic control module is to control the regeneration cycle. The control module has several variations. When replacing the controller, use the
same model or some functions may not work. This is an electronic controller that is programmable and uses input/output signals.
To remove control module:
1) Disconnect power to the unit.
2) Remove valve cover.
3) Press trip lever to release module from top plate.
4) Pivot the top forward and up.
5) Remove any wire connections. Wire connections have a locking tab that must be squeezed before removing.
NOTE: There is no need to label the wires. The keyed connectors will only plug back into one site.
To install control module:
1) Be sure the power is disconnected.
2) Check model.
3) Check routing of wires and plug them into the controller. Connectors will snap in place. Be sure that wires are properly managed through the clips on top plate.
This will prevent the wires from being caught in the camshaft.
4) Place bottom of module in position. The bottom will fit into a clip.
5) Pivot the top into position and snap in place. The controller should be secure.
If you are ready to program the controller, then power can be applied by plugging in transformer.

4-2
DRIVE MOTOR
The drive motor is open loop and receives commands from the control module. The motor has a pinion gear that meshes with the camshaft gear to drive (rotate)
the camshaft.
During operation, rotation forces the motor into its mounting position and screws or bolts are not needed.
NOTE: Some units will have a shipping peg in the top motor mount. The peg can be removed and discarded. This peg is not required for motor operation.
To remove motor:
1) Disconnect power to the unit.
2) Remove cover.
3) Pull off wiring connector.
4) Grasp the motor body and rotate to the left.
5) Pull motor out.
To install motor:
1) Insert gear through hole on top plate
2) With motor ears flat to the rear of the top plate, rotate to the right until mounting tabs are engaged in slots.
3) Reconnect wires.
NOTE: It is not necessary to pre-position the camshaft or the motor. When the controller is powered up the camshaft will be rotated to the “home” position.
OPTICAL SENSOR
The optical sensor is mounted to the top plate. The camshaft cup rotates through the sensor and the slots are detected. A signal is sent to the controller for each
slot.
IMPORTANT NOTE
Damaged sensors should be replaced. Sensors may be cleaned with compressed air or a soft brush.
To remove optical sensor:
1) Disconnect power to the unit.
2) Remove cover.
3) Remove controller.
4) From the controller side, pinch the legs of the sensor holder in the top plate.
5) Pull the holder away from the mounting surface.
6) Remove wires.
To install optical sensor:
1) Attach wires. Wires should point away from camshaft.
2) Place leading edge of sensor holder into opening.
3) Pivot holder into place. Legs should enter slots and snap in place.
IMPORTANT NOTE
The optical sensor legs are fragile and may break. If the optical sensor legs break or crack, we recommend replacement. A damaged sensor may result in
improper regeneration.

4-3
CAMSHAFT
The camshaft has several lobes that push open the valve discs as the camshaft rotates. Rotation is controlled by a drive motor that drives a gear at the rear of the
camshaft. The front end has a cup with markings and slots.
IMPORTANT NOTE
The camshaft slots are molded to exact dimensions. Do not attempt to modify the cam cup slots. Improper regen will occur!
The outside surface of the cup has an arrow mark. When the arrow is at top center, the camshaft is in the loading position. 90
degrees to the right on the cup an optical sensor is mounted to the top plate. This sensor reads the slots as they pass through.
The largest slot is “Home” and the remaining slots are positioned to signal the regeneration cycles.
When looking at the end of the camshaft, numbers are visible in the hollow of the cup. An arrow on the top plate points to the
current marking. The numbers represent regeneration cycles as follows:
C0 = Treated water - normal operation mode
C1 = Backwash
C2 = Brine draw
C3 = Slow Rinse
C4 = System pause
C5 = Fast rinse cycle 1
C6 = Backwash cycle 2
C7 = Fast rinse cycle 2
C8 = Brine refill
These numbers are offset rotationally 90 degrees from the matching slot. The offset enable the service person to view the number at the top of the cup and deter-
mine which slot is at the optical sensor.
IMPORTANT NOTE
If any part of the camshaft is broken or damaged the camshaft should be replaced. Do not repair or modify damaged cam lobes, gears or timing cup.
To remove camshaft:
1) Disconnect power to the unit.
2) Remove cover.
3) Remove motor.
4) Camshaft should be in the treated water position. Rotate to the left as needed.
5) Use a screwdriver to hold open the #1 valve disc.
IMPORTANT NOTE
When replacing/removing camshaft, make sure not to damage or misalign the optical sensor. Hold the sensor in position while removing camshaft.
6) Move the camshaft backwards, away from the controller.
7) Lift the loose front end up and out.
To install camshaft:
1) Check that the optical sensor is in position.
2) Position camshaft above the valve discs. The arrow on the cup should be up.
3) Slide the rear of the camshaft into place.
4) Pivot the camshaft close to its final position. The camshaft will push on one or more valve discs. You will feel resistance as you complete the installation.
5) Move the camshaft down and into position. Force valve discs to move as needed.
6) Move the camshaft forward. Check that the optical sensor is in position.
7) Install motor.
NOTE: The camshaft will position itself to C0 (treated water) when the controller is powered up.
