Control Start-Up Procedures (Cont’d)
1. Home Display
- Alternates Between the display of Time of Day and Number of Days Until the Next Regeneration.
- Days Remaining Until the Next Regeneration will Count Down from the entered Regeneration
Day Override Value Until it Reaches 0 Days Remaining.
-A Regeneration Cycle will then be Initiated at the next Designated Regeneration Time
-Metered models alternate the Time of Day and Gallons Left Until the Next Regeneration. The
meter will count down to zero and then regenerate at the scheduled time set.
2. Battery Back-Up (Uses a Standard 9-Volt Alkaline Battery)
- Installing the Battery
- Features of Battery Back-Up
Maintains the Time of Day During Power Failures
Notes: 1) During Power Failures, the Display is Turned Off to Conserve Battery Power.
However, to Confirm that the Battery is Working, Press Either Button and
the Display will Turn On for Five Seconds.
2) If Power Failure Occurs while System is Regenerating, the Isobar II Completes its
Current Position and then Pauses Until Power is Restored. The Next Position is then
Commenced from its Beginning.
3) When Used without Battery Back-Up, the Unit Acts Like a Standard Valve—When a
Power Failure Occurs, the Unit Stops at its Current Point in the regeneration Position and
then Restarts at that Point when the Power is Restored. However, the Time will be Offset
by the Increment of Time the Unit was without Power.

With Proper Valve Operation Verified:
1. Add water to the top of the air check. Manually step the valve to the
Brine Draw Position and allow the valve to draw water from the brine tank
until it stops. Note: The air check will check at approximately the midpoint
of the screened intake area.
2. Next, manually step the valve to the Brine Refill Position and allow the
valve to return to Service automatically.
3. With the valve in Service, check that there is about 3.0’ to 5.0’
above the grid in the brine tank, if used.
4. Fill the brine tank with salt to complete Set-Up. The control will run automatically.
There are four (4) error codes which could indicate a possible problem with the control valve:
Error 2 - Homing slot expected. Valve will begin searching for home
(Normal operation continues)
Error 3 - Encoder is not sending a signal
(Valve requires service to continue)
Error 4 - Unable to find homing slot
(Valve requires service to continue)
Error 5 - Motor overload (stalled position or shorted motor)
(Valve requires service to continue)
Error 5 Explanation: The unit thinks the motor is locked. This can only happen when the valve
is running the motor, it is not seeing any encoder slots, and the motor is overloaded. This
usually alerts the presence of corrosion inside the valve clogging the system

Master Programming Mode
To Enter Master Programming Mode, Press and Hold both Buttons for 5 Seconds.
Note: all Master Programming functions have been preset at the factory. Unless a
change is desired, it is NOT necessary to enter Master Programming Mode.
1. Regeneration Type (t)
-This Display is used to set the Regeneration Type. This option setting is identified by the letter ‘t’ in
the left digit. There are two possible settings:
-Timeclock / Filter Delayed – The control will determine that regeneration is required when the set
regeneration time has been reached. The regeneration frequency setting will determine which days a
regeneration cycle will be initiated. Example (t - - c)
-Meter Delayed (Demand) The control will determine that a regeneration is required when the
available volume of softened water drops to or below zero. Regeneration is to begin at the scheduled
time set. Example (t - - d)
•The Set/Change button will adjust this value. To accept the digit value press the
Menu/Enter button.
2. Regeneration Day Override (A) – Meter Mode Only
-Press Menu/Enter button. This display is used to set the maximum amount of time (in days) the unit
can be in service without a regeneration. This option setting is identified by the letter ‘A’ in the left
digit. Regeneration will begin at the scheduled time. A setting of zero will cancel this feature.
-Example: Override every 7 days (A- 07) or Cancel setting (A-00) Maximum setting is 29.
3. To Set Regeneration Time (r) Example [r 12A]
- The time of day at which a regeneration may take place is designated by the letter ‘r’.
- The first display digit indicates A.M or P.M. To change the value press the Set/Change button.
- Press Menu/Enter button to accept the value and move to the next digit.
- The second and third display digits indicate the hour at which the regeneration will occur.
- Change the Digits with the Set/Change button and accept with the Menu/Enter button.
- After the entire display flashes, press the Menu/Enter button to move to the next menu item.
2. 2. 4. To Set Regeneration Cycle Step Times (2)(3)(4)(5) Example [ # - 20]
- The next 4 displays set the duration of time in minutes for each regeneration cycle step.
- The step number which is currently modifiable is indicated on the far left of the display screen.
- The number of minutes allotted for the selected regeneration step is displayed on the far right.
- Change the digits values using the Set/Change and Menu/Enter buttons as described above.
Note on Air-Draw Cycle (5): Centurion Filter Only
The longer the unit is set to remain in the air-draw cycle (5), the more air is drawn into the system. A
default setting of 12 minutes draws air down to the level of a normal resin bed height and then returns
the unit to the home display. If the system needs more air, increase the time setting for step (5) or
change the number of days between air-draw cycles to 2-3 days (or lower than your current setting).
There is no way to view the number of days until the next air draw will take place.

5. System Capacity in Grains (c) – Meter Mode Only
-Press the Menu/Enter button. This display is used to set the system capacity in grains and is used in conjunction
with the hardness setting to calculate total gallons of treated water available between regenerations. This option
is identified by the letter ‘c’ in the left digit. The maximum value for this item is 399.
Example: 32,000 grain capacity (c 032)
6. To Exit the Master Programming Mode Press the Menu/Enter Button

Service Instructions
A. General Preliminary Instructions—PERFORM BEFORE ALL SERVICING OPERATIONS!
1. Turn off water supply to conditioner:
If the conditioner installation has a “three valve” by-pass system, first open the valve in the by-pass line,
then close the valves at the conditioner inlet and outlet.
If the conditioner has an integral by-pass valve, put it in the by-pass position.
If there is only a shut-off valve near the conditioner inlet, close it.
2. Relieve water pressure in the conditioner by stepping the control into the backwash position momentarily.
Return the control to the service position.
3. Unplug electrical cord from outlet.
4. Disconnect brine tube and drain line connections at the injector body.
B. To Replace Brine Valve (need first A1-A3?)
1. Remove the control valve back cover.
Disconnect the meter signal wire from the
meter
2. Remove screw and washer at drive yoke.
Remove powerhead mounting screws. The
entire powerhead assembly will now lift off
easily.
3. Remove piston retaining plate screws and pull
upward on end of piston yoke until assembly is
out of valve.
4. Pull brine valve from injector body, also
remove and discard O-ring at bottom of brine
valve hole.
5. Apply silicone lubricant to new O-ring and
reinstall at bottom of brine valve hole.
6. Apply silicone lubricant to O-ring on new
Brine valve assembly and press into brine
valve hole, shoulder on bushing should be
flush with injector body.
7. Insert screws through injector cap and into
mating holes in the valve body. Tighten screws.
8. Reconnect brine tube and drain line.
9. Return by-pass or inlet valving to normal service
position. Water pressure should now be applied
to the conditioner, and any by-pass line shut off.
10. Check for leaks at all seal areas. Check drain
seal with the control in the backwash position.
11. Plug electrical cord into outlet.
12. Set time of day and cycle the control valve
manually to assure proper function. Make sure
control valve is returned to the service position.
13. Make sure there is enough salt in the brine tank.
14. Start regeneration cycle manually if water is hard.
C. To Replace Injectors and Screen (need first A1-A3?)
1. Remove injector cap screws, remove cap and
discard gasket. Remove vortex generator from
