leak test procedure
Always leak test with the engine off.
1.
Charge the system with sufficient refrigerant to have a gauge pressure of at
least 340 kPa (50 psi) with the system off. At ambient temperatures below 15 °C
(59 °F) leaks may not be measurable because the pressure may not be
reached.
2.
Visually trace the entire refrigerant system, and look for signs of air conditioning
lubricant leakage, damage and corrosion on all lines, hoses and components.
Check each questionable area with the detector probe, as well as all fittings,
hose-to-line couplings, refrigerant controls, service valves with caps in place,
brazed or welded areas, and areas around attachment points and hold-downs
on lines and components. If looking for an apparently larger leak, check first at
the medium (7 g/year) or low (14 g/year) sensitivity setting.
3.
Always follow the refrigerant system around in a continuous path so that no
areas of potential leaks are missed. If a leak is found, always continue to test
the remainder of the system.
4.
Recheck the service valves with the caps removed. Blow shop air over the
service valve to clear the immediate area. Check with a detector on the medium
sensitivity setting (7 g/year).
5.
Move the detector at a rate of no more than 75 mm/s (3 in./s) and as close as
possible to 9.5 mm (3/8 in.) from the surface, completely encircling each test
position (switch, sensor, refrigerant tubing connection, etc.).
