경고

A/C 냉매 누출 감지 절차(18200200)를 수행하지 않는 한, 누출이 확인된 냉매 시스템을 재충전하지 마십시오. 이는 불법이며 환경에 해로우며 차량의 열 시스템을 손상시킬 수 있습니다.

경고

모든 필수 인증 교육을 완료한 기술자만 이 절차를 수행할 수 있습니다. Tesla는 타사 서비스 제공업체 기술자가 이 절차를 수행하기 전에 동등한 교육을 받을 것을 권장합니다.

유럽/중동/아프리카 지역의 경우, Tesla 기술자는 현지 A/C 또는 F-가스 인증 외에도 열 관리 및 A/C 시스템 작업을 하기 전에 에어컨 안전 필수 교육을 이수해야 합니다.

경고

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.

경고

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.

경고

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.

경고

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.

경고

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.

경고

Be aware of fire hazards. Do not use the A/C machine in the vicinity of spilled or open containers of flammable liquid.

경고

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.

경고

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.

경고

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.

경고

Only use the specified type of A/C oil.

경고

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.

경고

Always keep refrigerant oil in its original container, tightly sealed, and clearly marked so as to prevent contamination of any kind.

경고

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.

경고

Always maintain different oil canisters for different types of oil. These canisters should be clearly marked to avoid any cross-contamination between the oils.

경고

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”.

경고

Always reference the information label to determine the refrigerant capacity of the vehicle. Do not over-fill or under-fill the A/C system with refrigerant.

Recovery

CAUTION

Failure to follow these recovery instructions could cause catastrophic damage to the A/C system.

Perform a calibration check of the A/C machine. Refer to the A/C machine operator’s manual for instructions on how to perform a calibration check of the A/C machine. If the machine fails the calibration check, do not use the machine until a service representative has calibrated the A/C machine.
Inspect the entire length of the hoses and fittings for degradation, cracks, or damage. Make sure that the condition of the hoses and fittings is such that they will not leak when in service.
Inspect the A/C machine’s power supply cord and plug that they are not damaged and the insulation has not been compromised in any way.
Make sure to use the appropriate type of A/C oil.
Set up the A/C machine.
Remove the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
Remove the cabin intake duct. See .
Remove the access panel. See .
Remove the underhood storage unit. See .
Unlock the vehicle gateway. See .
On the touchscreen, touch Service Mode > Thermal > Refrigerant System > Start Thermal Fill Drain (Refrigerant Only) and select Run to start the "Start Thermal Fill Drain (Refrigerant Only)" routine.
Wear appropriate personal protective equipment.

Warning
R134a and r1234yf refrigerants are dangerous liquids and can cause serious injury if handled improperly. When recycling or recharging the air conditioning system, you must wear appropriate personal protective equipment (PPE), including face shields, heat-resistant gloves, rubber boots, aprons or waterproof overalls.
Remove the caps from the A/C high pressure and low pressure ports.
Connect the red high pressure hose to the A/C high pressure port, and the blue low pressure hose to the A/C low pressure port.

Note
The high pressure and low pressure ports are of different sizes, and match the hose couplers accordingly.
Follow the A/C machine instructions for recovering refrigerant and oil from the vehicle.
Take note of or print the amount of refrigerant (approximately 1000 - 1040 g) and oil (approximately 8.87 ml) recovered after recovery is complete.

Note
The A/C machine chimes when recovery is complete.
Determine whether the A/C desiccant bag should be replaced.
