OK Guys.
I suppose I should know the answer to this question, however truth is I have not got a clue.
I have a friend that has an Ammonia charged fridge which he wishes to install on his motor boat.
I know from the quick look I had at the fridge there is a 1/2" bsp fitting so a std charging hose would fit.
But as we all know this side of the "black art" is rarely covered.
Any thoughts anyone?
