I have a 2016 Tab 320 and have used the Alde just a very few times.
Does the amount of use have anything to do with the need to replace the glycol?
Should I automatically replace the glycol after 2 years or should I somehow do a ph test to see if there is a problem?
Has anyone made a detailed youtube video showing the process?
Thanks

Regarding glycol replacement: the manual States it should be done every two years to maintain anticorrosion properties. (But it doesn't tell you how.) Manual is here:

I hope there is/will be a good solid answer that doesn't involve driving to a dealer in another state or renting/shipping a pump from/to NüCamp. This should be a DIY operation with a written procedure available to do it with any needed tools available for purchase at a reasonable price.

This spring, i think ours tested a little off (a year older than yours?), so I changed the glycol.

- Drained the glycol.
- Tipped the Tab every which way until no more glycol came out
- Added clean distilled water to rinse system of old glycol
- Drained distilled water
- Return to step 3 & repeat until distilled water drains clear
- Refilled the glycol - used 100% glycol, not premixed, to be able to adjust % with water
- Tipped the Tab every which way with the Alde pump running to bring air out
- Opened the bleeder screw now and again to release trapped air
- Topped off the glycol reservoir
- Return to step 7 & repeat until no more room to top off.
- Ran the Alde pump for days, then checked the freeze protection, adding more 100% glycol if necessary, to adjust % to correct solution
Needless to say, it was not very scientifically done. (And it wasn't done right, according to Alde)As I said in another thread, I did measure what came out, and it wasn't enough. There is one loop of the heating system that just won't drain easily. Maybe if I turned the Tab upside-down a couple of times...
As I also said in that previous thread, I don't recommend you follow my example here. I think a pump is necessary, unless you're willing to put another drain port in the system to be able to fully drain it.
HTH! 😉

I would think chemically all propylene glycol would all be similar even though DOW is a different brand. It looks like heat and oxygen can degrade the fluid over time and I suspect the reason for the frequent change recommendation. The frequent change may also be an FDA requirement in USA too, there must be some Federal agency regulating the use in USA, as Europe is allowed to use ethylene glycol which is much more toxic to your health in case of cross contamination between the heating and domestic water cylinders in the Alde. Since they can use the toxic stuff in Europe there much be almost no chance of contamination or they would be sued out of business by now by anyone who has been poisoned.
