1999 Hunter 310 Air Conditioner new install

[crewzen]

I currently own a Hunter 27, however I am purchasing a 1999 Hunter 310. It does not have air conditioning and the brochures and schematics on the Hunter site do not show the location or technical data on where a factory air would be installed. Could anyone please help me with materials needed as I determine the size and placement of a AC/Reverse Heat unit for my new boat?
I have read through a lot of other forums, and all I could find was some info in a 320 ( http://forums.hunter.sailboatowners.com/showthread.php?t=117205 ),
but I would really like the specific information for the '99 310.
Any help would be greatly appreciated.
Thank you very much,

I found the factory diagram for the 99 Hunter 310. I have ordered a Mermaid 1650 AC with reverse heat. It goes under the galley sink with vents in aft berth, in the fore cabinet door and I am opting for another vent on the starboard side under setee. I have already ordered the unit and my marina tech has begun prep. Thanks for the suggestion. If anyone needs the diagram for the 99 310 in the future, I have scanned it and can email it, or anything else in the original notebook from Hunter.

Don't forget a a/c vent in the head if possible.

On my H356. I have a 16.500btu under settee in front of gallery sink ducted for main saloon and forward cabin and then I installed a 5200btu. next to it under the starboard settee. That way I could utilized factory ducting to aft cabin which then feeds around under aft bunk to head. Under v-berth forward locker port side another 5200btu with duct going going up back side of port closet locker to a distribution box with a 4" round adjustable damnper to forward cabin and then a small rectangular vent to main saloon port side. All mermaids are using separate little giant raw water pumps. And can operate independently of each other. So now I have lots of redundancy and options for keeping cool down here in the republic of Texas on Galveston bay.

I got several of my pumps from here. http://search.aquaticeco.com/index?D=little+gaint&Nty=1&N=0&Dk=0&Ntt=little+gaint

A Good source while shopping around. Or you can check out eBay.

Reason I like little giant is one of my pumps as been faithfully doing its job for about 12 years. Make sure you pick out the model for use on saltwater aquariums. Also pick the largest pump your budget can go. The 12 yr old model I have will suck the chrome off a buick!

Also do not forget to install a venturi at the a/c discharge sea-cock. http://www.aquaticeco.com/subcategories/1546/Turbo-Venturi-Injectors

This will keep the a/c pan sucked dry. Or let the pan drain to bilge and then put the suction hose in bilge. Tryed it both ways, finally settled in on pan option.

I am getting the condensator for the unit. I have one on my other 27' and it works great and keeps everything nice and dry. Thanks for the info

Tryed that expensive one mermaid sells. It failed after a short while. Not worth it. Got the one you see pictured in post before. Only about 20-25 bucks. Much better. Forget all that filter and check valve crap. I looped the small suction tube up about 12"s above a/c discharge sea-cock and then to the a/c pan. That a/c discharge is never under water unless the boat is moving at about 5 knot any way which creates a suction on end of small hose in a/c pan. Think just like that old sunfish.
Did something really scary once while sailing offshore at about 7+ knots had to unscrew the sea-cock next to keel to get that plastic garbage bag out of it. So we could run the a/c. The suction was incredible. Yelled up to my crew as I was doing this, what ever you do don't stop the boat or we will sink!!!:wow:
