ACCESSING HISTORY VALUES
The control features a review level that displays the operation
history of the system. This is a great troubleshooting tool for
the control valve.

Salt Amount button and hold for 3 seconds to view the
Diagnostic Codes.
NOTE: If a button is not pushed for 30 seconds, the controller
will exit the history table.
Press the Time of Day button to increment through the
table. When the desired code is reached, Press the Salt Amount
button to display the value.
Some of the values have four digits 1, 2, 3, 4. Press the Salt
Amount button to display the first two (1, 2). Press the
Water Hardness button to display the last two (3, 4).
When the Salt Amount button is pressed to view H2 the
current flow rate will be displayed but not updated. Continue to
press and release the Salt Amount button every 5 seconds
to update the display. The flow dot on the display will flash
when there is flow thru the softener.

START-UP
The conditioner will now need to be placed into operation.
Please review Quick Cycling the Control procedure before
attempting start-up.
DO NOT put regenerant material into the brine tank.
1. With the supply water for the system still turned off,
position the bypass valve to the “not in bypass” (normal
operation) position.
Both valve
handles pointing
in direction of
water flow
2. Press and hold the button on the controller for 3
seconds. This will initiate a manual regeneration, and cycle
to the backwash position.
3. Filling the media tank with water.
A. With the conditioner in backwash, open the water supply
valve very slowly to approximately the 1/4 open position.
Water will begin to enter the media tank. Air will begin
to be purged to drain as the media tank fills with water.
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 debris from the
media bed.
D. Pour water into the brine tank. Advance to cycle 2 (Brine
Draw) by pressing the and buttons at the same
time. The water in the brine tank should be drawn into
the valve. If the water is not receding from the tank,
refer to Troubleshooting.
E. Quickly cycle the control to the refill cycle (C7). Place
salt in brine tank. Allow this cycle to finish and the
control to move to service. The brine tank will have the
correct amount of water.
WARNING: Ensure that the system has been properly
disinfected per the water conditioning system
manufacturer's recommendations.
The water conditioning system is now fully operational.
The display will show the hour of the day. The decimal point at
bottom center of the display will blink when water is flowing.
