Hi Jeremy, I cut a hole for access and have a suitable stainless steel louvre plate to fit later, connected the charging hose and gauge reading a vacuum, added 5 seconds of gas which then gave positive readings, added another 5 seconds which gives suction pressure of 12 psi so slightly over pressure. The refrigerator has been running for over three hours with bottles of water as load, now running 45% of the time. Will check again tomorrow to see if pressure is holding and running time less. This is the first gas added in 16 years, maybe a small leak, time will tell.
Well pleased with the response and support from other Dufour owners.
Kind regards Phil
