- If you're installing a new A/C condenser, add refrigerant oil (SANDEN SE-10Y). Using the wrong refrigerant oil can be a safety hazard.
- 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, dispose of any remaining oil in the container, due to moisture absorption and short shelf life.
- 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.
- Be careful not to damage the radiator or the A/C condenser fins when installing the A/C condenser.
