HELPHOS accessory pressure hose with valve - how to use it?

[Ofir]

Hi,
I should get my HELPHOS accessory pressure hose with valve can be connected between the spare wheel and the container.

Please let me know how to operate it:

1. How much pressure the spare wheel need to be 2.5 bar or 3 bar?

2. Short hose goes to water tank and long hose goes to spare wheel?

3. What's the purpose of the small knob? when I shoud use it?

4. What's the purpose of the valve (ventil) in the bottom of the accessory?

Thanks

The hose passes the same pressure from the spare tire to the wheel, it just cuts it off when the pressure gets low, keeping the spare from going flat. I'd keep closer to 2.45 bar.

I do not know how to fix this. All I can say is it all works fine for me with what I use, Firefox.

Do you have answers to the questions above?

Don't go that high. I've seen an early tank split in half. They are rated 35PSI. The cutoff valve on the early style accessory hoses is more like 18PSI.

The owner's manual says 36psi for the stock system. Perhaps try that and see it it works?
