Heating/Airconditioning on Searay 375 Sedan Bridge

[nigelsmith]

Hi I have an issue with the heating and aircon. When I first used it water was expelled from the boat, presumably to cool the system. Now, when I have the heating on nothing is being expelled. The system seems to be working okay. Do I have a fault?

Have you taken the boat out since this occurred? You may just need to prime the pump? You can do that manually, but getting the boat out on plane works as well. I have had to do this a few times.

If your system is like mine after a few minutes of AC (fan) running and no water discharge you should get a fault code at the stat. and unit should turn off. This happened to me and like Michael said the pump lost the prime.

Once you've verified that the pump is primed, if there is till a problem, it could be the relay is bad (or embarrassingly - the seacock is closed. I did this once). The relay is what turns on the water pump independent of the A/C unit(s)

If you are getting heat, you probably have electric heat, not reverse cycle.
