Sunsation A/C
 

Did you check to see that it was moving water?

It will dump overboard thru a thru-hull fitting. Next time check to see that it is moving water.

Ok. Where’s it pull the water from? I assumed it was self contained

Depends how it was setup and installed. A/C on a cruiser pulls water from a pickup in the hull. Not sure if they installed a pickup in the hull or added a hose attachment in the engine compartment to where it could be ran on a lift out of the water. Or maybe it has both? Does it also have an inverter and bank of house batteries to where you could run it out on the hook? Pics of the valve he had you open and surrounding plumbing along with a pic if the unit itself would be helpful.

BTW, I cannot imagine it would be setup to source the water any place other than the lake/ocean as depending on the size, they move a lot of water. But who knows.

the boat came from Sunsation with air conditioning, so no aftermarket. Inside my cabin I have three shore power breakers. Dual battery charger-microwave-A/C I’ll post a photo of the valve. Thank you for the guidance

The factory is very helpful on answering questions. Don't be afraid to give them a call.

I had air in my 32 so here's what I had to do, Make sure valve is open, Take a hose and clean out the line from the front up where the sink dumps out. you should see water running out the pickup hole which is in the bottom of the hull in the rear once you get water to rear close valve and go to your lake or river, plug in open valve and turn air on( its takes awhile to kick on) if it does not kick on take the floor in closet loose and pick up there should be a red reset button on top of the unit that you may have to reset as it gets hot and shuts everything down,If that does not work you'll have to find the pump and see if its working. I know it is a pain in the ass to get water if the system runs dry and I would have to reset the unit 3 or 4 times if I forgot to close the valve and all the water ran out of the line/
