    • Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the correct O-rings for HFC-134a (R-134a) to avoid leakage.

    • Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.

    • Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.

    • Make sure that there is no air leakage.

    • Charge the system.
