On my 2014 SO 469 the boat was built with three air conditioning units. These are CruiseAir systems. The condensate does not really drain, instead it apparently is led to an orange air pump that is supposed to dry the pan out. It makes no sense to me to pump moisture into the air but that’s how it has been explained to me. And the little air pump leaks now. I am planning on removing the orange small air pump and leading the drain hoses to the bilge. Has anyone else done this? Does anyone know if the little air pump explanation I received is correct? Thanks.

Same thing on my boat, except they pump the condensate down into the bilge.

Thanks. Obviously I have some learning to do on the system. It sounds like either overboard or to the bilge makes sense and we’re used.

Interesting to get this system figured out. The pump portion of mine is hidden beneath the blower and hard to see. This was a factory install. All three of the condensate pumps lead to a 3 to 1 fitting and a dedicated through hull very near to the cooling water outlet midship. Once more it took a few Jeanneau owners to clear up the misinformation previously received. If it helps anyone: the pumps on mine are “Aspen Mini Orange” pumps. According to some reports these don’t last as long as desired but mine work now with just an occasional clean out of the float switch.

My SO439 has the same orange pumps. I have replaced each one at least once over past few years.
One seemed to get stuck in active mode (even after disconnecting float sensor cable). It had been running for an unknown period of time while I was away from the boat for a few days. Upon my return, it was very hot to the touch when I noticed it was running constantly. As it is a 120v pump I was concerned about it being a fire hazard since it was so hot.
The filter screens have dissolved or corroded away over time which allowed the float disk to get gummed up which prevented the pumps from switching on. Have replaced the screens a few times now.
The mini-pumps seem to be problematic and I considered one of the Venturi type solutions, but have heard mixed results for those devices. I have considered trying to route the condensate to the main bilge to be pumped overboard. Instead, I found the orange pumps on eBay at a deep discount so I bought several as back ups and to cannibalize spare parts.

Those Aspen pumps were developed for residential ductless split A/C units. Their main advantage is that they are extremely compact. They definitely don't like a lot of restriction on the discharge tube, and when they fail they usually just stop pumping. That's when they run continuously and get really hot. I wouldn't consider them a fire hazard. They get hot, but nowhere near hot enough to start a fire.

I wouldn't consider them a fire hazard. They get hot, but nowhere near hot enough to start a fire. I know they are supposed be “thermally protected”, but they can get very hot. When mine failed it was not due to any restriction in the discharge tube. The reservoir was dry, tube was empty, pump was just running endlessly even after removing the sensor cable. A local marine HVAC tech says he only installs blue mini-pumps. Not sure if it’s an Aspen unit or from other source. I may look into those once I run out of Aspen spares.

Mine ran for quite a while when the float got dirty and stuck on. I didn’t feel that it got dangerously hot but it was noisy. The only way to shut it down was to shut off the electric power to the A/C circuit.

It seems to me that the arrangement above would also eliminate the bilge pump going off at all hours and keeping the crew awake! A common complaint for aircon condensate running into the bilges.

Same pumps on my boat to through hull.
Open the reservoir (carefully) and ensure filter is clear (sometimes gets bunged up). Be certain to replace the magnetic washer the correct way around (magnet up).

Yup. In my case the magnet was upside down.

We took ours off in the Fall and now having issues hooking up again. I see the power and the thru hull for expelling the condensate. Just can't find the 'pump portion' but will take the vent cover off on the seat and should be able to see the area under the blower. Thank you!

HI ALL, On board my boat SO 40 DS I have a 22000 BTU AC unit and it produces a huge amount of condensate water. For the first couple of month I let it run into my bilge and expect bilge pump to get it out. It was so frequent and noisy so I looked for another way. 220/120 volt pump involving wet humid is something I want to avoid. I took a 5 liters camping water jar with a wide opening and installed an old washing machine float attached to a 4$ tiny Chinese 12v mini pump ,a 10 mm plastic hose runs to my toilets basin. You must put in some drops of chlorine once a season to avoid growth in the water. Perfect, no noise, no need for filtration and if anything goes wrong, water will flow into the bilge and pump will tell you all about. Those pumps are maintenance free and I always keep couple of them just in case. my original set is working fine for the last 5 years.

No AC here but I had to look, and that's a brilliantly efficient and simple solution-- an engineer's delight: less. Why have more pumps and a plethora of extra failure modes when one pump is the only axiomatic requirement of the system?

Solution: Non electric Venturi or directly drain it to the bilge.

Solution: Non electric Venturi or directly drain it to the bilge. Not only crap but even worse: redundant and therefore crap that is not needful and is simply wasting time, money, energy, space etc. An engineering offense on multiple counts. Anybody struggling with this should take a look at the product cited by Ania.

Hi Moonshadow, I was looking at the float switch today which pumps the condensate out of the pan. You mentioned you clean out the float switch. How do you do that? It looks like the cover just pops off, but didn't seem to budge for me.

The top / plastic cover pops off to support cleaning the float box. Be sure to reseat the screen properly after removal and ensure the the circular magnetic float is installed on the guide in the same orientation as it was removed.

I have a 41 DS and replaced the mini orange pump twice on the AC unit in the saloon. Now I believe the mini pump below my aft AC unit is not operating properly, however, this AC unit is installed behind the headboard of the rear birth; anyone know how to access the rear AC so the mini pump can be inspected and the condensate pan cleaned out?
