[C320-list] Air Conditioning

12k vs 16k? I have to admit the 16k will handle high load conditions better
than the 12K, stands to reason. It is simply a judgment call. The 16
Cruiseair unit is about an inch taller than the 12k and we didn't want to
give up that in the bread box. Also, as was brought to our attention by
Denny at Annapolis Cruiseair, many AC units don't deliver their rated output
- a problem well known with many products we buy. He assured us that this
unit had been completely redesigned by Dometic to perform to specs. There
are also other points such as the non-metallic condensate pan designed to
deliver nearly all of the condensate to the drain. It won't rust, it won't
spill.
We installed a venturi type valve that pulls the condensate from the pan and
incorporates it into the overboard discharge. I tested this recently by
pouring a cup of water into the condensate pan. The water was quickly pulled
out by the venturi action leaving the pan nearly dry. Of course the innate
port list helped encourage the water to leave the pan. (:>)
Only time will tell if we made the right choice. Denny was quite confident
that the 12k would do the job.

I feel your pain. I've had the boat for three months and it hasn't left
the slip. -:)
