NWTS AIO3 -- Larger head of O3?

[Ĝan Ŭesli Starling]

For my 10-inch tank, the Ozotech AIO3 program manual settings recommend:

Filtering = Air
Air Release = 4.0 min
Backwash = 14 min
Air Draw = 40 min
Rinse = Off
Regen Capacity = 1000 Gal
Regen Type = Normal
Relay 1 = On
Actuation Time = 19:00 min
EOG Active Length = 38:00 min
Relay 2 = Off

But that assumes 1.5 CUFT of Katalox Lite. Whereas I have 1.0 CUFT, it having been recommended to go with less and employ a larger head of O3.

But, if you please, what program settings need to be changed for said larger head of O3?

Filtering = Air

Programming instructions according to the Ozotech AIO3 manual: https://www.manualslib.com/manual/1856069/Ozotech-Aio3-Systems.html?page=8#manual

- the Filtering setting should be 'Regen'
- Your current 14-minute BW duration should be suitable
- 'Air' draw should now be indicated as 'Brine'. Continue with the current 40-minute setting.
- Programming steps 5, 6, 7 & 8, should all be set to 'OFF'
- step 9, 'Relay 1' to be set 'ON'
- step 10, 'Actuation Time' (when O3 generator becomes Activated), set to 15-minutes, which will be 1-minute after the 14-minute BW cycle has concluded. Your current 19-minute setting, is needlessly delaying activation of the O3 generator until 5-minutes after the conclusion of the BW cycle.
- Continue with the 38-minute 'EOG Active Length' setting to establish if the now longer run time (+ 4-minutes) will be suitable. If additional O3 is further needed, both the 'Brine' draw and 'EOG Active Length' settings will need to be increased.

As a catalyst, Katalox Light® is not consumed in the iron removal process and it does not need to be regenerated. Also like most other iron removal media, the active ingredient in Katalox Light® is manganese dioxide.

Above is quote from Katalox Light OEM. Hence the NTWS AIO system filtering set as AIR, not REGEN. There is no brine in this system. The 19 minute activation is not over-delayed insofar as AIR RELEASE = 4 minutes, preceding BACKWASH = 14 minutes, hence 18 minutes total. Activating the ozone generator at 19 minutes is one minute beyond that.

The Ozotech manual you quote is possibly for an ordinary Clack 5-button valve and not the NTWS variant thereof? Just speculating...

I'm still in the dark as to which of those settings regulates the size of the O3 head left in the tank. I would like it to be greater.

Semantically IMO, if you have a periodic process that sucks in air, rather than brine, that could still be called a regeneration, don't you think?

Also, from a timing and valving point of view, I expect the air cycle is the same as a brine draw cycle. But customizing the firmware to call the cycle air, rather than brine, would make sense. I would not be surprised if there was no specific Ozotech valve service manual available. Clack does not make even their softener service manual easily available to end customers I expect.

I obtained PDFs of service manuals for my NWTS valves (proprietary Clack variants) from the vendor. The settings I initially quoted derive from the paper manual "AIO3 Ozone Installation & Programming Guide" which came with the "AIO3-OZONE-NELSON-FIELD-KIT", but for which I have no PDF.

Of some import, as I understand it, the very first cycling step is "Air Release", allowing for controlled venting of the O3 head bubble. Then follows backwash. I hesitate to try any configuration lacking an "air release" phase for fear of a surge where the backwash step might hit the valve outlet like a hammer.

In lieu of a top basket, this Nelson AIO valve has affixed a AIO Air Blocker, which is kind of like the middle tier of a 3-tier fountain. Shining a light through the Almond painted tank from its opposite side, I can observe the shadow plural streams of water trickling down.
