Re: A.M.F.A fresh water pump on A54

You either need a new Square D pressure switch, and it adjusted correctly, or you need to adjust the current switch. If you have never adjusted the switch, you may find the 2 adjustments difficult as it is not intuitive.
Don't kick it as the rubber mounts will easily break.
Amel installed 2 different A.M.F.A/Reya fresh water pumps. The 66b and 88b. The 66b cutoff pressure is about 2.0 bar...turn ON at about 0.6 bar. The 88b settings are higher.
The accumulator air pressure should be measured with 0 bar water pressure in the freshwater system. Generally the air pressure should be 10-15% less than the cutoff water pressure.
There is a lot more in my 400 page Amel Book.
