Are the A/C units going off on high pressure cutout ?Has anybody figured out an easy way to flush the AC system. I have an 07 model and believe I have a barnacle build up in the lines and/or ac coils. Especially the forward or stateroom AC. My thinking now is to find a way to sort of wedge two hoses into the discharge ports and create some kind of low pressure seal for recirculation of an acidic solution. Unfortunately the seals at the discharge ports that I have in mind may not work and if they do will require 3 people to perform this task. Hoping somebody here has a better idea.
I built a flush kit to use on the 44 from the plumbing isle at Home Depot. I ran a return hose thru the cabin back to the engine hatch for the forward unit and put a quick disconnect splice in the overboard hose for the salon unit just above the isolator transformer. I used a mixture of muriatic acid and circulated for about ten minutes and was amazed at the debris that was cleaned out. Just remove the 'out' line from the heat exchanger on the forward unit and clamp a hose to it to run back thru the cabin. Use a long enough hose to not need a junction to avoid a possibility of a leak in the cabin. It is a one man job this way.Has anybody figured out an easy way to flush the AC system.

I didn't even read your post yet man! Where the hell have you been? Welcome back.I have 3 units (Salon, State Rooms and the bridge). I routed bridge AC discharge right next to the salon discharge. So those two are very easy to reach for creating circulation. I just stuck a 5/8" hose with couple rounds of electric tape and it worked very well.
State rooms is the more involved one, so I can offer two options (assuming the boat is in the water):
1. Blow the line with air compressor to clear remaining water. Run the acid solution until you see it dripping out of the discharge. Let is sit for an hour, then flush with city water.
2. Disconnect the discharge side from the AC unit and run it back to the bucket. The short run between the unit and the discharge can easily be flushed with city water.
Both options require one person, but obviously it'll help having an extra person alerting you when solution is coming out of the discharge.

I’m pretty sure 6.5”. You could always measure one to be sure.Hi, does anyone know the size of the speakers in the ceiling of the salon? About to bid on some and not sure of the size. Thanks
A few months ago I got a few gallons of barnacle buster and went to big box stores for fittings and used garden hoses to create a closed loop to flush each engine, generator, and both ac units. Amazing how yuck the recirculated solution got.Has anybody figured out an easy way to flush the AC system. I have an 07 model and believe I have a barnacle build up in the lines and/or ac coils.

I got my boat back in the water yesterday and brought her home. I tried using the trim tabs while at cruise speed and I had no problem burying the bow. I tried going up and down several times while at cruise speed so they had to work against the water pressure and so far each time I was able to really dig the bow in. Next month will really tell as we head to Bahamas with much more weight. Hopefully they continue working well.Looking forward to your feedback.

Thank you for all the responses with excellent advice. I used this method as it didnt require a seperate pump. Seemed to work very well.Like others, I made my own system. Basically created a closed loop from the discharge side of the AC's and ran a hose back to 5 gallon bucket in the bilge positioned near AC water circulation pump. I removed the hose from the intake side of the pump and ran a "jumper hose" to the same bucket which I filled with Barnacle Buster (BB). Once all was set up I turn the AC pump on and using a hose with freshwater, prime the pump (kind of like a pool filter). Once primed and all the air is out I quickly place the intake hose into the nearby bucket filled with BB. End result is continuous circulation "closed loop" of Barnacle buster through the system/AC. Ever so often I would shut pump down and let sit for 10-15 minutes making sure I don't lose the prime. The crud that came out into the bucket was unbelievable and the contents of the bucket quickly turned black the first time I did this. I immediately did it a second time with fresh BB and it eventually cleared to something acceptable. Same process applies for my other AC unit. I now do this process ever other year. BB is a lot safer that using acid approach - which probably works better - but is a bit scary to work with. The fittings and hose I used were all purchased at a local hardware store. Took a little time to get the set-up right but now it's a piece of cake. Very easy to do and well worth the effort. Before I button the forward AC up I will usually will blow some BB into that line to clean it as well. I used a small garden sprayer and do it a few time before flushing.
This goes back to mid-April - I ordered these and went to install today. The instructions on the package show to mount the cabinet ball 255mm (10") below the top of the cabinet ... my cabinets are only 8" high! Am I mis-reading the instructions or maybe your cabinets are higher than mine?
