Winterizing AC on R29S LE

[S. Todd]

Owner's manual shows the middle through hull on the STB side is for the Forward AC. When I operate the Forward AC to get antifreeze through that AC the discharge all comes out the second through hull from the rear (in the group of 5 through hulls) which is for the Aft AC. How do I get the antifreeze to go through the Forward AC and its through hull? As far as I can tell there is just one water pump for both AC Units which is consistent with page 19 of the Owner's Manual.

Hi Todd. Your 29S may be different then the one we had, so keep this in mind. I had to take the hose off of the inboard side of the sea strainer, lift the hose upright and pour RV antifreeze into it as I ran the ac units one at a time. Hope this helps.

I am able to get the pump to prime through the sea strainer so I am not having any problem getting the antifreeze into the pump. The problem is it always comes out the aft AC through hull regardless of whether I am running the aft air conditioner or the forward AC.

I got it to work. Solution = Wait a day, install a T Fitting to get easier prime on pump, purchase a #5 rubber plug and insert it into the aft AC through hull (ask wife to hold it in when starting forward AC while being careful not to get doused with antifreeze coming out of the forward through hull fitting). In the interest of not pumping additional amounts of antifreeze through the aft through hull I did all three at once so I am not sure which had the most impact - but mission accomplished.
