Is This A Problem?
We just picked up a Keystone Bullet 246RBS last week and I am in the process of cleaning it up. It sat on the lot for a while. I removed the outside frig vent and was wondering if the twisted pipe i...

The tank is the 'absorber tank'-----where helium and ammonia collect
The bent/kinked tube is where rich & weak ammonia solutions flow----rich ammonia goes to perk tube. Weak ammonia mixes with ammonia/helium solution and flows back to absorber tank.
That kink is restricting the flow of rich ammonia solution. It is lowering the efficiency of cooling unit because of reduced flow of rich ammonia solution.
These cooling units (absorption---helium or hydrogen---same) are based on unrestricted gravitational flow. The more ammonia vapor produced and the rapidly condensed back into liquid the better the cooling effect.
Any restriction/reduction in flow (off level, blockages, bent/kinked tubing etc.) results in lower cooling effect.
Back to dealer.......replacement of fridge.
And if dealer says 'normal' 'no problem' have them put that in writing with Atwood Representatives signature also on it.
Them go open another fridge vent and show them no bent tubing as that is what is 'normal'
