    WARNING: Servicing must be carried out by personnel familiar with both vehicle system and the charging and testing equipment. All operations must be carried out in a well ventilated area away from open flame and heat sources.
    CAUTION: If equipped with refrigerant checking devices, it is recommended that the system is tested prior to recovery. Air conditioning (A/C) systems filled with incorrect refrigerant can cause damage to vehicles system and the equipment used to service them.

  1. Refrigerant recovery.

  2. G11545117

    Remove the dust covers from the high and low pressure connections.

  3. Connect the high and low pressure lines to the appropriate connections.
    4. WARNING: Refrigerant must always be recycled before re-use to ensure that the purity of the refrigerant is high enough for safe use in the A/C system. Recycling should always be carried out with equipment which is design certified for compliance with SAE J2099 and SAE J2788. Other equipment may not recycle refrigerant to the required level of purity. R-134a or R-1234yf Refrigerant Recover Recycling Recharging stations must not be used with any other type of refrigerant.
