I will be winterizing tomorrow. I have located one inlet hose in front of the galley sink. I will detach and put the hose into gal. or two of antifreeze. I have two controls for the Ac one located next to the sink and one is located in the aft cabin. Is this inlet the only inlet.Since there are two controls,is there another unit that I have yet to locate with its own inlet. The one unit is located under the single settee across from the table.I hope I haven't confused anyone. Your help is most appreciated.....Thanks!

easy way to tell

I don't think anyone would wire two controls to one compressor. Easy way to tell is turn on each one at a time to see if they both control the compressor. You probably have a second under the aft berth, with it's own water line and should be able to hear it.

RJ, on my 410, the A/C inlet in the galley is the only one. the pump and manifold distribute to the two A/C units. Bryce S/V Spellbinder H410

only need one

the a/c water pump will put water/anti-freeze to both units at the same time so no need to use any other controls. You may need more then a gallon or two, suggest you have 4 or five to be safe.

I use less than 2 gallons for my two A/Cs in my...

h40.5- nearly the same as your 410. Take care not to lose prime on the pump because it is not self-priming and it must be below water level to fill and pump. Losing prime is very easy to do when you are removing the hose from the seacock. I would suggest having a drill pump handy to force the antifreeze into the pump to re-prime it.
