The Adler/Barbour Super Cold Machine on my recently purchased boat is circa 1985 vintage. The original installation appears to have been professionally done, there are no restrictions in the air or water cooling, the compressor operates, but the evaporator is barely cool to the touch. It has no audible hiss, only a faint gurgling sound.
Anyone have experience with recharging the refrigerant in this vintage? Is it even possible with more recent EPA restrictions?
I welcome any/all comments. Mike
