The Eradicator O
3
functions just as a standard Eradicator Filter with the addition of ozone that is pro-
duced during the air intake. The ozone is produced from ambient air that is entering the induction port
during the Regeneration Down cycle. The ozone generator is turned on through the Gen II AQx Relay
Function, after the control valve has already stopped in the Regeneration Down cycle, and air draw is
active. The ozone generation is not turned on during Back Wash or Rinse Cycles, and turns off before
the control exits the Regeneration Down Cycle. Turning off the ozone generator before the valve moves
from the draw cycle provides fresh air to run through the tubing, clearing out all ozone from the control.
Ozone remains in the tank air chamber until it is converted with service flow. The ozone can be purged
from the tank if desired with special programming. If it is desired to operate without the trapped air in
the head of the tank, refer to the instructions in the Tech Bulletin on programming to remove the air.
The ozone generator activates when needed through the Relay 1 module of the AQ x software. Relay
1 is set to Regen Time. The start point is set to the number of minutes that it takes the control to enter
the Regeneration Down cycle, plus one additional minute before turning on. This allows the control
to stop in the cycle and establish a stable draw of air into the control. The Relay 1 terminal block is
connected to a relay that turns the ozone generator’s auxiliary power supply on.
Factory Set Program Time:
Back Wash 8 Minutes
Relay 1 - Set
Regen Time
Rinse
4 Minutes
Relay 1 - Set Point Start 13 Min
Regen DN
30 Minutes
Relay 1 - Duration
28 Min
This says that the AQx Relay will activate 13 minutes after the start of the cycle, and turn off after 28
minutes from the start of the relay activation. The initial 13 minutes allows the control to stop in Regen
DN before ozone is produced, and it turns off the ozone after 28 minutes, which is 1 minute before the
control returns to service.

with Ozone
Note: When stepping the control manually through the cycles, with the REGEN button,
the Relay function is disabled. To check the ozone production, the cycle can be manu-
ally started, but the control must proceed with the time to reach the Relay Set Point. If
you push REGEN at any time during the cycling process, the Relay will not activate, and
if already activated, the Relay will turn off.
