[C320-list] Marvair Condensation Removal Kit

[Warren Updike]

Mark, we and another 320 owner in our marina installed AC at the same time although we put it in the port locker up against the salon bulkhead. We both installed the MarvAir CR330 and can highly recommend this device. And this was 6 more years ago. I feel confident that the CR330 would easily lift your condensate enough to deposit in the outgoing cooling water discharge. We have never had a problem with it, and the small strainer in the line has never collected any detritus. I would attach to the cooling water discharge as far from the thru-hull as possible to avoid any possibility of air reaching the CR330 while the AC is running. That might break the vacuum needed for the CR330 to operate.

Let us know how this goes,

Subject: [C320-list] Marvair Condensation Removal Kit

I'm thinking about buying a Marvair CR330 condensation removal kit to remove condensation from the air conditioning on my 320, but have run into a potential problem with the way it would have to be installed.  The condensation drain from the evaporator/air handler appears to be a few inches lower than  the through-hull for the cooling water discharge from the condenser/compressor unit. (Both units sit on a shelf above the fuel tank in my starboard lazarette, but the discharge comes from the top of the compressor and the condensate drains from the bottom of the air handler.)

 

Does anyone know whether the venturi in the Marvair CR330 generates enough suction to lift the condensation a few inches to the discharge line?  I looked at the installation guide on-line, but it doesn't directly address the question.  And I tried e-mailing the manufacturer, but haven't received any substantive response.  

 

So do any of you have any information based on your own experience?  Any help would be appreciated.
