Schematic for T@B 400?

rayze

We brought home a T@B 400 yesterday, previously we were T@B and T@DA owners, so have familiarity but as we read through the owner's manual we saw mention of a schematic coming soon. Is that available? Would be awesome if the manual included a layout and description of items similar to when you purchase a sewing machine. For example, in the bathroom behind a cubby is a plastic container that is filled up to the MAX line but we have no idea what that container is, how do we refill it, what is the purpose????

Sounds like the Alde overflow tank.

Thanks! Do we have to do anything other than monitor the levels?

In the bathroom?  Usually the glycol expansion tank is located in the closet--unless you have the larger 3-way refrigerator instead of a closet.  Then it is located on the driver's side of the dinette forward the porthole window.
Do you have a 2020 TAB 400?  Then all bets are off as there has been some serious relocation of equipment since the 2019 version.

We do have the larger 3-way frig. I'll have to go look in the morning, I don't remember if the expansion tank is in the bathroom or by the dinette. We just picked up the 400 yesterday so still getting to know it.

The Alde manual you got should discuss the gylcol but of course it is non Tab specific so wouldn't tell you actual location as that varies by model and even within the same model depending on options.

I bought a gallon of the correct fluid on Amazon as ours burped some out in first week, while not rare, it probably isn't on the shelf at every RV store either, so good to have on hand. That fluid also needs changed (like an oil change) at I belive two year intervals.

you were correct about the location of the expansion tank beside dinette window and cubby.

Reading manuals is next on the list. :-)

This 400 owner put together a good guide.
