Checking For Leaks

A/C REFRIGERANT SYSTEM (R-134A), CHECKING FOR LEAKS




Use halogen leak detector Hitec HI400A-TEL or equivalent to check for refrigerant leaks.

Refrigerant gas 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 in order to check for leaks.

- check A/C system for leaks following leak detector manufacturer's instructions
