Refrigerant System

Leak Detection:





- Use Hitec H14OOA-TEL halogen leak detector (or equivalent) to check for refrigerant leaks
- Refrigerant dissipates very quickly. Avoid drafty or windy areas when checking for leaks
- If the refrigerant system is discharged (empty), charge system with approx. 100 g (3.5 oz) of refrigerant to check for leaks
- Check A/C system for leaks following leak detector manufacturer's instructions.
