LEAK TESTING
It is of the utmost importance that a leak check is made on the 4 flare nut connections. A leak,
however small, will result in the aircon system losing capacity and endanger the compressor.
1. Use either soapy water, or a proprietary leak test solution.
Paint on each flare nut (particularly the neck) and inspect carefully for any telltale bubbles. Use a torch
to improve visibility, particularly in the A/H area.
Any leak will generally be remedied by further tightening of the flare nut. In the event of a faulty flare,
the line valves must be turned off, the A/H pumped out, and the flare remade.
2. Use an ELECTRONIC leak detector - preferred.
Test initially on low sensitivity, examining in particular the neck of each flare nut. Increase the
sensitivity until you are confident that no leak exists.
