STEP 12:
Press and hold the REGEN button (4) until the motor starts. Then use the NEXT button (1) to
advance the control valve to the backwash position (refer to pages 9 and 10 for details). When
the backwash countdown begins, unplug power from the valve.
STEP 13:
Refer to Figure 4 bypass valve operation. Rotate the INLET knob of the bypass valve slightly
toward the Service position (just enough to hear water entering the tank) allowing the unit to fill
slowly (be patient). Filling the mineral tank with the control valve in the backwash position will
purge air from the mineral tank to the drain.
STEP 14:
When all air has been purged from the system and only water is running to the drain, slowly
rotate the inlet knob of the bypass valve to the “Service” position and do the same for the outlet
knob.
STEP 15:
Plug power back into the control valve. The display will return to the time of day. Then press
and hold the REGEN button (4) until the motor starts and advance the control valve to the
BRINE DRAW cycle using the NEXT button (1). Verify that the water level in the brine tank is
dropping. Allow water level to drop below the top of the salt grid before continuing. If the water
level does not drop, refer to page 25 for Troubleshooting. After verifying water level is dropping
advance control valve to the time of day using the NEXT button (1).
STEP 16:
Check for leaks and correct as necessary.
STEP 17:
Turn power or fuel supply back on to water heater.
STEP 18:
Press and hold the CHECKLIST button (3) until the screen changes to set the hardness & iron
concentrations on the control valve (refer to Installer Settings, Page 13, for details), then press
DONE.
STEP 19:
Press the SET button (1) to set the current time of day on the timer (Page 8, note AM and PM).
STEP 20:
Add at least 40 lbs of water softener salt to the brine tank. Any type of water softening salt
may be used.
