George,

I don't have an Adler Barbour system, but hopefully someone else does and can help you out with more specific info.

By the way, here's a link to the Nigel Calder Refrigeration book, available on Amazon.com.

Many thanks, Dave.

I do have Calder's book, and a basic understanding of the charging/purging process. What threw me off is that Calder places emphasis on the importance of monitoring

David the leak is where the compressor piping joins the evaporator piping. That is the only fitting on the system, but the leak

This is what I have found works (NOTE - I AM NOT A REFRIGERATION EXPERT!!!)

Tighten all of the connections on the refrigeration lines, Start the system, put a little refrigeration in the system (maybe a second or two), wait five minutes and feel the evaporation plate, if it is cold let it run for @ an hour, if not shoot a little more refrigerant into the system. Your goal should be the entire plate gets cold and @ 4" of the line can be iced. Just keep adding refrigerant @ 1 hour increments until the system is working. You can 'bubble' the connections to see if you have a leak. Most likely the pump quit and you over pressured the system thus losing a little refrigerant.

I am sure there are people with more expertise on this forum.

Hello all,

Currently my wife and I are on land in Maine where I work for Hinckley repairing yacht systems. We sold our Van deStadt 36 in 2003 after 15 years living aboard (which included 4 years living in the hull while building the boat). We spent 5 years in Ft Lauderdale where I worked for Beard Marine A/C and Refidgeration. We hope to sell our restored 1865 Cape and move back aboard a CSY 44 or 37 as since I couldn't afford one in the 70's I have always admired them. I just found this site 10 minutes ago and will read the refer question and post a repy. For now.. if the refridgerant is gone there must be a leak...find and fix the leak..

Robin

Peter's suggestion is an good one if you have no refridge tools.. You could detect the leak with a refriderant "sniffer". Tighten the fitting, attach your gauge manifold to the access port to evacuate the system with a vacuum pump and weigh in the correct charge using a scale like the CPS refriderant scale. The type of refridgerant and the weight of the charge should be written on the system name tag on the condensing unit. If the system uses R-134a you can buy it at NAPA or Walmart. If it's anything else you will need a licence to purchase the refridgerant. A Johnston Supply catalogue will show you all the options for spending money on tools.

Harbor Freight sells refrigeration gauges and an evacuation pump (it works with your air compressor). I would suggest tightening the connections slightly, add a little refrigerant, check for bubbles, and see if it works before evacuating the system and weighing the load. Remember the marine refrigeration systems don't take a lot of refrigerant so losing a little will have a big impact.

If it does not work then you can buy the tools and do the complete job.

Thank you very much for all the help I received on the subject.

Peter Roach's suggestion works...I am happy to report. My unit may not be charged to peak (I was maybe overly cautious in charging) .....but it works... and the procedure is simple..

No problem. My philosophy is to start with the easiest solution first and work up in complexity. Surprising how many time the first thing works. Glad it did this time.
