Recommended Aqua-Sensor
NOTE You might find it useful to pre-test the sensor probe in your shop. The same
test setup can be used in the field.
1. Close the main water supply valve.
2. Install the sensor probe into the tank but do not connect the sensor to the control at this time.
Set the Cul-Flo-Valv® to the BYPASS position.
3.
4. Ensure that all faucets at the installation site are closed.
5. Direct the drain line discharge into a bucket where flow can be observed.
6. Plug the transformer into a 120 Volt, 60 Hz, single-phase receptacle (make sure to connect both
24V and 2.5V properly).
7. Complete the First Time Set-up.
8. Open the main supply valve.
9. Initiate an immediate regeneration to move the control into the BACKWASH position.
10. Refer to the section on manual cycling for information on cycling the control through its posi-
tions.
11. When in the BACKWASH position, slowly rotate the bypass to the soft water position until
water flows.
12. Continue BACKWASH until the drain effluent is clear and the Aqua-Sensor probe is placed in
the resin bed—at least 10 minutes (use a white foam coffee cup to occasionally collect a sample
of backwash water; the stark white of the cup will show the presence of color throw and resin
fines).
13. Continue or repeat the BACKWASH cycle if needed.
14. After the backwash water runs clear, step the control to the REFILL position to fill the brine tank
and purge air from the brine line.
15. Unplug the control and connect the sensor to the circuit board.
16. Reconnect the power and INSTALL the Aqua-Sensor Probe (Main Menu/ Accessories/
AquaSensor)
17. Check the condition of the Aqua-Sensor (Main Menu/ Diagnostics/ Checksensors)
18. Press the Program key and program the control to the desired settings.
19. Complete installation and cleanup.
20. Sanitize the unit as you leave the installation (see
21. Initiate an immediate regeneration.
The thorough backwashing process should have cleared the fines and color-throw from the tank. The
probe should settle into the resin bed during the first couple of minutes of backwashing.
