Leak test with the engine not in operation. 3. The air conditioning system shall be charged with sufficient refrigerant to have a gauge pressure of at least 340 kPa when not in operation.
  • Page 8 User’s Guide 7. At each area checked, the probe shall be moved around the location, at a rate no more than 25-50 mm/s and no more than 5 mm from the surface completely around the position. Slower and closer movement of the probe often helps locate the exact position of the leak.
