PROGRAMMING

If the system is a twin alternating conditioner
CAUTION
(278A), go to "Quick Cycling the Control for Twin
Alternating Systems".
Quick Cycling the Control
It is required that the control be quick cycled to specific
regeneration cycles when placing the system into operation.
This will ensure that all of the air in the tank and valve is
purged. The process also provides a check for leaks and
functioning of the brine system. Please perform the following
steps for quick cycling the control before proceeding to start
up the system.
1. With the control in the treated water position, press and
hold the REGEN button on the controller for five seconds.
This will initiate a manual regeneration. The control will
display a solid hourglass indicating that the motor and
camshaft are turning to the backwash cycle (C1). When the
control reaches the backwash cycle, the total regeneration
time remaining will be displayed. Pressing the SET button
will display the specific cycle time remaining.
2. While the controller is in cycle C1 (Backwash), open the
water supply valve very slowly to approximately the 1/4
open position. Water will begin to enter the media tank.
Any air remaining will begin to be purged to drain as the
media tank fills with water.
If opened too rapidly or too far, media may
WARNING:
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.
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 the way. This will purge the final air
from the tank.
Allow water to run to drain until the water runs clear from
the drain line. This purges any debris from the media bed.
3. Press and release the UP and SET buttons to move the
control to the Regenerant Draw cycle (C2).
4. Add water to the regenerant tank.
A. With a bucket or hose add approximately four gallons
(15 liters) of water to the regenerant tank.
B. If the tank has a salt platform in the bottom of the tank,
add water until the water level is approximately 1" (25
mm) above the platform.
It is recommended that you do not put regenerant
NOTE:
into the tank until after the control valve has been
put into operation. With no regenerant in the tank, it
is much easier to view water flow and motion in the
tank.
5. Check regenerant draw.
6. Repeat step 3 to advance to each cycle.
Before the final filling of the media tank with water, check
that:
• The nearest water faucet is completely closed.
• The valve drain line is properly routed to a drain.
• The regenerant tank is empty and the regenerant hose is
connected to the valve.
• The water supply valve is off.

The control can be sent directly back to the treated
NOTE:
water position from any regeneration cycle. Press the
UP and SET buttons (for about five seconds) until the
hourglass icon begins flashing. The control will now
skip all remaining regeneration cycles.
A. C2 will be displayed. With the control in this position,
check to see that the water is being drawn out of the
regenerant tank. The water level in the regenerant tank
should recede very slowly.
B. Observe that water is being drawn from the regenerant
tank for at least three minutes. If the water level does
not recede, check all regenerant line connections for
air leaks.
7. If the water level is receding from the regenerant tank you
can quick cycle the control to the C8 Regenerant tank refill
position.
A. The control will cycle to the regenerant tank refill cycle,
and water will be directed down through the regenerant
line to the regenerant tank. Let the water flow through
the line until all air bubbles have been purged from the
line. Note: Do not let the water flow down the line to the
tank for more than one to two minutes, or the tank may
overfill.
As you advance through each cycle there will be
NOTE:
a slight delay before you can advance to the next
cycle. There will be a pause after the regenerant
draw and slow rinse cycles. This cycle (C4) is a
re-pressurization cycle and is designed to allow
the water pressure to equalize on each side of the
valve discs. Allow the control to re-pressurize (three
minutes) before cycling the control to the regenerant
tank refill position.
8. Finally, turn on a faucet plumbed after the water
conditioner. Run the faucet until the water runs clear.
9. Add the appropriate amount of regenerant to regenerant
tank.
The System is Now Fully Operational
After any control reset (valve type or system
NOTE:
change, etc.), it is necessary to initiate a manual
regeneration and quick cycle through it. This will
ensure the control and cam are synchronized. If not
synchronized, Err3 will display and the control will
drive cams to the correct position for the valve and
system type programmed.
Quick Cycling the Control for Twin Alternating
Systems
It is required that the control be quick cycled to specific
regeneration cycles when placing the conditioner into
operation. This will ensure that all of the air in the tank and
valve is purged. The process also provides a check for leaks
and functioning of the brine system.
After the initial power up and programming, Tank 1 will be in
standby and Tank 2 will be in service.
Before the final filling of the media tanks with water, check
that:
• The nearest water faucet is completely closed.
• The valve drain line is properly routed to a drain.
• The regenerant tank is empty and the regenerant hose is
connected to the valve.
• The water supply valve is partially open.
• Valve bypasses are in service positions.
