Need an AC wizzard

[Paul B]

The air conditioner in my boat is a 110 volt unit that is water cooled.
It takes F22 freon. I added freon and now it shuts off on high preasure. I keep removing freon but it still shuts off in a few minutes.
The water supply is good, no clogged filters.
I don't have guages any more but I borrowed some when I added freon.
Any Ideas or would you want to come over and take your girlfriend on a moonlight cruise? Bring your guages.

I wish I could help I don't have gauges but when my central was not working it was because there was too much pressure in the lines (which I guess is why u need the gauges lol)

I put the freon in with guages but it reads on the boat ,high preasure.

What's your low side and high side read also what's the cap on the f22??

I would have to bring guages back to the boat because I forgot the numbers, but the stats are printed on the unit. It seemed like after I added freon, sometimes the reading would jump very high. But I filled it to the amounts it stated.
It now runs about 2 minutes and cuts off, the digital guage reads Hi

Paul,

The chance are the gauges could be bad. Best bet is to get your hands on a second set of gauges to verify.

I'm not a pro but am a DIYer and have come across the same problem in my case on a car it was a clogged dryer/filter they tend to go bad from what I was told over time from absorbing moisture

1--check to make make sure there is water going thru the water jacket i am assuming that it is sea water
2----if you addded freon thru the service valves make sure they are back seated stem on valve all the way out (unless the port is being used for pressue control then all the way out and 1/4 turn in )
3---high head in that short of time should be easy to find reason
--- your head pressure should be no more than 225 pounds if you over charged

thasts a couple to get you started

There is plenty of sea water flowing through the system.
I will borrow guages again and test it. I know it was pretty close to the readings posted on the unit, but then they went all the way up.
