- Vacuum A/C system to remove any moisture potentially trapped.
- Replace the receiver/drier desiccant bag if any of the following conditions occur:

- Amount of refrigerant extracted is < 30% of the required quantity.
- Refrigerant circuit has been open for an indefinite period of time (gradual leak, exterior damage to condenser).
