[C320-list] Air Conditioner install questions.

[Monte B.]

Jim,

I also used the engine raw water through hull as the water source for my AC
install but without a valve to cut off the AC water when he engine is
running. There seems to be ample water in the lake to supply both at the
same time and I have never had a cavitation issue since the install. You
might leave the isolation valve open and try it.

Dave,

When I installed my AC, instead of having a new thru hull installed I just
installed a Tee in the engine sea water intake line after the strainer, and
put a valve on the branch to the AC pump. When you want to use the the AC l
Leave the thru Hull open and open the valve to the AC, When you are going to
use the motor you shut the valve off to the AC. Although you got to remember
to make sure the appropriate valves are open, depending on what you want, it
has works well and saved a extra thru hull being installed.

Thanks everyone for your responses I've already got the the outputs ducted
to both the main and rear cabins and have the electrical in place.  Really
the water source and air return were the big questions.  I'm going to try it
starboard for now tucked way in and I just called the marina to haul and put
the through hull in for the feed (doing my best this year to keep one marina
employee fully employed).  It will be easy to change over the winter to the
other side if I find it annoying as I will not be cutting the large return
through the fiberglass.  I'm going to make a vented door to put in place for
now for return air flow similar to what is listed below.  the height of the
door is
11.25 inches which means a 2' piece of 1x12 will work just fine (cheep).  If
I'm 
happy I'll cut a vent into the original door next season.   I don't know if
my 
workmanship will stand up to the rest on the association web side but I'll
take pictures.  
 
Spent last year high and dry due to work schedule so I'm making up for it
this year in $1k boat units.  So far new shaft and bearing, new batteries,
1000w inverter and new AC unit not to mention for the first time ever I had
the yard prep, wax and bottom paint.  So I put the inverter and AC (for the
most part) in.

I installed a 16,500 BTU Marineair unit in hull #620 in 2003 and mounted it
to port directly behind the aft berth bulkhead behind the small access door.
I cut the return air grill into the door and mounted the AC flush with the
door/bulkhead on a mount I made from marine plywood and 1" x 1" legs. The
noise is certainly an acceptable trade off for getting rid of some of the
TX. heat and the noise is at my feet instead of my ears. The condensation
issue is solved by installing a hose in the condensation pan running to a
venturi tapped into the water pump discharge line which carries the
condensate water overboard with the discharge water. The install did not
noticeably affect the C-320 port list and preserved the starboard shelf for
stern anchor, PFD's etc. You do however lose the access to the hell hole
through the door and it makes adjusting the steering cables a bit more of a
chore. This location also makes routing the duct work much less difficult. I
would not try to duct the return air as more ducting = less unit efficiency.

I vaguely remember a post where some one T'd off a drain for AC water.  Does
any one have info or photos.  Also looking for same on installation of AC
unit in starboard aft locker.  Rather than cutting return vent near the unit
was considering venting the small hatchway in aft cabin by so I did not have
to listen to the unit quite as much.  Theory being return air could go
through vented hatch to unit on starboard shelf.

Any opinions welcomed.
