[C320-list] Air Conditioner install questions.

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.
