A/C Refrigerant System (R-134a), Checking And Testing

A/C Refrigerant System (R-134a) Leak Testing
Use halogen leak detector Hitec H1400A-TEL or equivalent to check for refrigerant leaks.

Refrigerant gas dissipates very quickly. Avoid drafty or windy areas when checking for leaks.

Some refrigerant leaks are apparent by refrigerant oil deposits on or near the leak location. Confirm by using leak detector.

If the refrigerant system is discharged (empty), charge system with approx. 100 g (3.5 oz) of refrigerant in order to check for leaks.

- Check refrigerant system for leaks following leak detector manufacturer's instructions.







- Check for refrigerant leaks by passing detector probe under suspected leaking components.
