My boat's ancient Alder Barbour ColdMachine finally gave up the ghost. This was an icebox
conversion - the icebox
is a toploader in the galley
, with an evaporator in it, and the compressor
and whatnot is just on the other side of a bulkhead, mounted in a cockpit
locker. The copper refrigerant lines, and the thermostat wire, run through a small sealed hole in the side of the icebox, through the bulkhead, and to the Danfoss.
After many hours of troubleshooting, I found that the problem is in the electronics
, on the control board - a part which can't be replaced. The compressor
runs fine, and system is fully charged with R134a.
I have purchased a new Vitrifrigo cooling
unit with a forced air condenser, and a new evaporator. I have only done troubleshooting on my old system, never installed something like this, so I am immediately confronted with a new problem: how can I safely vent the refrigerant in the installed system? I mean safe for me and for the environment
. I am guessing that I need to disconnect the fittings that lead in to the Danfoss, but I'm worried that 1) I'll freeze my fingers off; 2) I'll break the law.
Any advice on the removal
of an old reefer and the installation
of a new one would be very greatly appreciated. My usual go to book - This Old Boat - has nothing to say on my particular problem.
