Hardness
• System capacity is displayed in total kilograins or kilograms
of hardness removed before a regeneration is necessary.
• Value is derived from the system’s resin volume input and
salt amount input.
• The capacity is displayed for information purposes on the
740 control. It cannot be changed.
• To change capacity on the 762 control, press SET to make
the default capacity flash. Use the UP and DOWN buttons
to increment to the desired capacity.
• Press SET to accept the setting and advance to the
next parameter.
• FA filters: see section on capacity, Setting the 700 for FA
Filter Applications.
If using the 742 control, programming is complete. The control
will return you to the normal operation mode.

Hardness
• Enter inlet water hardness at installation site.
• Default hardness setting is 25 grains (ppm for metric).
• To change hardness, press SET to make the setting flash.
Use the UP and DOWN buttons to scroll to the
desired hardness.
• Press SET to accept the entered hardness value.
• The control will return you to the normal operation mode.
• FA filters: see section on capacity, Setting the 700 for FA
Filter Applications.
Initial system programming is now complete. The control will
return to normal operation mode if a button is not pushed for 30
seconds.
Viewing Cycle Times
1. Press and hold the UP and SET buttons for 3 seconds when
the control is in the "in service mode" to access the "cycle
time display mode". The display will show a small "c"
followed by a number in the lower portion of the display.
2. Press the UP and DOWN buttons to display the
programmed cycle time.
3. Press the REGEN button to exit the "cycle times display
mode".
Adjusting Cycle Times
1. Press SET when in the "cycle time display mode". The cycle
time in minutes will flash, indicating the cycle time can be
changed.
2. Press the UP or DOWN buttons to change the flashing
time.
3. Press SET while the cycle time is flashing to enter the
flashing value.
NOTE:
The draw and refill cycle times cannot be changed
in cycle time programming for conditioner valves.
Draw and refill times are calculated using the draw
and refill rates and salt amounts. The draw and refill
cycle times may be programmed for filters.
Conditioner and FA Filter Start-Up
After you have performed the previous initial power-up steps, you
will need to place the conditioner into operation. Follow these
steps carefully, as they differ from previous valve instructions.
WARNING:
Do not rotate the camshaft by hand or damage
to the unit may occur. Use the controller to
step the camshaft electronically through
the cycles.
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 positioned.
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.
WARNING:
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 any air trapped to
escape from the tank.
5. Add water to the regenerant tank (initial fill)
(conditioner and FA filters only).
A. With a bucket or hose, add approximately 4 gallons (15
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.
