Leak Test

1. Attach an air Conditioning Service Station.
2. Open high pressure valve to charge the system to about 100 kPa (14psi), then close the supply valve.
3. Check the system for leaks using a leak detector.
4. If you find leaks that require the system to be opened (to repair or replace hoses, fittings, etc.), release any charge in the system according to the Discharge Procedure.
5. After checking and repairing leaks, the system must be evacuated (see Evacuation).
