Winterizing the 12000 BTU Mermaid HVAC unit - 2013

November 2013 - s\v Elegant'sea is currently in Paradise Village Marina in Banderas Bay Mexico (by Puerto Vallarta)

 We took off the 3\4 inch hose from the through hole valve and put our 3\4 inch Spectra Watermaker 200T Deluxe pickling hose on it to give the hose some length.

Winterizing the 12000 BTU Mermaid Marine Air HVAC unit was much easier than we thought it was going to be. We had to pump fresh water through the system removing the sea water. Because we do not like the water at La Cruz Marina we chose to do it here at Paradise. The small Mermaid Marine Air 5200 BTU unit we can still use for sleeping and winterize at the anchorage as it will run off the inverter. We will use the water in our water tanks for that flush.

 We thought we might have problems with the March Pump not self priming as they do not. That did not happen and all went well. 

 

 Then put that hose in a pale of water and used the garden hose to keep filing the bucket. All went well and all done and all ready for next summer!

Of course the weather never gets any where near freezing here or you would add antifreeze or some other method :😄
