Sanitize 2023 Tab 320 - How to bypass Alde?

danmcgrath2014

I have watch the two 2023 Tab 320S "winterize" and "de-winterize videos.

I am trying to extract how to sanitize the system.

How often should I sanitize the water system?

Prior to 2023, we were instructed to bypass the Water Heating System by using the bypass switch in the 2022 Nautalus.
The bypass switch is missing.

In the 2023 de-winterize video, no mention is made of by passing the alde. Just use the "Nautilus sanitation configuration?

After sanitizing the fresh water system, should I empty and refill the alde water tank (boiler) with fresh water? How do I do that?

The 2023 t@b 320s has the Nautilus P3 system, which automatically bypasses the Alde tank when in "sanitize" mode,  Many older t@bs had a separate bypass lever, which is no longer needed with this version.  So yes, just use the sanitize mode.

And because you bypassed the Alde tank with the bleach solution, there is no need to flush it when you are done.

There is no need to flush. However, if you want to, there is a yellew handled valve next to your Alde. Lifting the lever up will dump the tank. Put the lever down when done.

It's interesting that they tell you to bypass the Alde tank when sanitizing but if you don't sanitize the whole system you haven't really sanitized the system. Just getting the Alde water hot won't do it either. If you open that bypass valve before a full boil you've contaminated the rest of the system again. It really needs to boil and I don't think you will get there heating that water with the Alde. I play it safe and sanitize and flush the whole system.
