Avertissement
À moins d'effectuer une procédure de détection de fuite de réfrigérant de climatisation (18200200), NE PAS recharger un système de réfrigération si vous savez qu'il présente une fuite. Cela est illégal et nocif pour l'environnement, et peut endommager les systèmes thermiques du véhicule.

Avertissement
Seuls les techniciens qui ont complété tous les cours de la certification requis sont autorisés à effectuer cette procédure. Tesla recommande aux techniciens fournisseurs de service tiers de suivre la formation équivalente avant d'exécuter cette procédure.

Pour la région Europe, Moyen-Orient et Afrique, en plus de toute certification locale relative à la climatisation ou aux gaz fluorés, les techniciens Tesla doivent suivre la formation « Air Conditioning Safety Essentials » (Essentiel de la sécurité en matière de climatisation) avant d'intervenir sur les systèmes de gestion thermique et de climatisation.

Avertissement
Only personnel familiar with both vehicle A/C systems and the A/C machine are permitted to service the systems. Always read and understand the A/C machine operator’s manual before operating the A/C machine.
Warning IconA warning icon, calling your attention to a possibly risky situation
Avertissement
Refrigerants R134a and R1234yf are hazardous liquids and, if handled incorrectly, can cause serious injury. Suitable Personal Protective Equipment (PPE), consisting of face protection, heat-proof gloves, rubber boots, and apron or waterproof overalls, must be worn when performing recovery or recharge on the air conditioning system.
Warning IconA warning icon, calling your attention to a possibly risky situation
Avertissement
Do not breathe refrigerant and lubricant vapor or mist. Exposure might cause personal injury, especially to the eyes, nose, throat, and lungs. Perform service and repairs in a well-ventilated area. If accidental discharge occurs, ventilate the work area before returning to work. Additional health and safety information is available from equipment, refrigerant, and lubricant manufacturers. Refer to manufacturer's instruction manuals and Material Safety Data Sheets.

Avertissement
Avoid using an extension cord on the A/C machine whenever possible. If an extension cord is used, it might overheat and cause a fire. If you must use an extension cord, use the shortest extension cord possible with a minimum 14AWG wire rating.
Warning IconA warning icon, calling your attention to a possibly risky situation
Avertissement
Do not use compressed air to pressure test or leak test the A/C machine or the vehicle A/C system. Some mixtures of air and refrigerant are combustible at elevated pressures. These mixtures are potentially dangerous and might result in fire or explosion, causing personal injury or property damage.
Warning IconA warning icon, calling your attention to a possibly risky situation
Avertissement
Be aware of fire hazards. Do not use the A/C machine in the vicinity of spilled or open containers of flammable liquid.
Warning IconA warning icon, calling your attention to a possibly risky situation
Avertissement
If you are operating the A/C machine in an environment where temperatures exceed 120 degrees Fahrenheit / 49 degrees Celsius, you must wait 10 minutes between tasks.
Warning IconA warning icon, calling your attention to a possibly risky situation
Avertissement
Never transfer refrigerants to a cylinder or tank unless it is Department of Transportation approved for refilling. DOT approval is indicated by the designation “DOT 4BA” or “DOT 4BW” stamped on a tank’s collar (handle). If a refrigerant tank is overfilled, it might explode. Be aware that when transferring refrigerant into a tank, the safe filling level must be controlled by weight, and must not exceed 60% of the tank’s gross weight rating.
Warning IconA warning icon, calling your attention to a possibly risky situation
ATTENTION
Only use Tesla-specified refrigerant in the vehicle A/C system and the A/C machine. Do not mix refrigerant types within a vehicle A/C system or in the same container. Mixing refrigerants can severely damage the A/C machine and the vehicle A/C system.
Warning IconA warning icon, calling your attention to a possibly risky situation
ATTENTION
Only use the specified type of A/C oil.
Warning IconA warning icon, calling your attention to a possibly risky situation
ATTENTION
Do not allow refrigerant oil to come in contact with any surfaces of the vehicle as it might cause damage to the paint, trim, or finish of the vehicle.
Warning IconA warning icon, calling your attention to a possibly risky situation
ATTENTION
Always keep refrigerant oil in its original container, tightly sealed, and clearly marked so as to prevent contamination of any kind.
Warning IconA warning icon, calling your attention to a possibly risky situation
ATTENTION
Do not over-fill the vehicle’s A/C system with oil. Replace only the exact amount that is removed. Always measure the amount of oil extracted and refill it with that exact amount.
Warning IconA warning icon, calling your attention to a possibly risky situation
ATTENTION
Always maintain different oil canisters for different types of oil. These canisters should be clearly marked to avoid any cross-contamination between the oils.
Warning IconA warning icon, calling your attention to a possibly risky situation
ATTENTION
The refrigerant cylinders currently in use as source tanks are disposable cylinders. Before they are discarded, connect the disposable refrigerant cylinder to the recovery equipment and bring to a vacuum to ensure that all of the refrigerant has been removed. Then mark the cylinder “Empty”.
