Refrigerant Handling
Do not inhale air conditioner refrigerant or lubricant fumes.
Possible irritation to eyes, nose and throat.
In addition, for environmental reasons, we strongly recommend using recovery/recycling/recharging equipment when removing R-134a refrigerant from the A/C system.
In case of accidental leakage from the system, ventilate the work area before resuming service.
Do not perform pressure or leak tests on service equipment and/or the vehicle's air conditioning system using compressed air.
Some mixtures of air and R-134a have been shown to be flammable at elevated pressures.
These mixtures can cause an accident or property damage if ignited.
Additional health and safety information can be obtained from the refrigerant manufacturers.
Avoid leaking refrigerant near open flames or heat sources.
Toxic gas can be generated when the refrigerant comes into contact with an open flame or heat source such as a cigarette and a heater.
When performing work that may cause refrigerant leakage, extinguish or remove the indicated heat sources and provide adequate ventilation.
Handling liquid refrigerant is hazardous.
Skin contact with refrigerant may cause local frostbite.
Wear gloves and goggles when handling refrigerant.
If refrigerant gets into your eyes, rinse immediately with clean water and consult a doctor.
Refrigerant storage
The refrigerant container is under pressure. If the container is heated, it may explode, dispersing metal fragments and liquid refrigerant, causing serious injury.
Store refrigerant at temperatures below 40°C.
Actions in case of insufficient refrigerant level
If insufficient refrigerant level is found during troubleshooting, do not recharge (add) coolant.
Since the exact amount of refrigerant cannot be determined from the pressure in the system, never recharge the system with refrigerant.
If too much or too little refrigerant is missing, there may be secondary faults in the system, such as damage to individual components or deterioration in system performance.
Therefore, if insufficient refrigerant level is detected, completely remove the refrigerant from the system and charge the specified amount of refrigerant.
Compressor oil handling
Use only ATMOS GU10 oil in the compressor of this car.
Using PAG oil instead of ATMOS GU10 may damage the air conditioning compressor.
Be careful not to spill ATMOS GU10 oil on the vehicle.
If oil gets on the surface of the car, it can damage the paintwork.
If oil gets on the car body, wipe it off immediately.
Compressor oil ATMOS GU10 (PAG oil) absorbs moisture more effectively than the previously used mineral oil.
If moisture gets into the compressor oil, the air conditioning system may be damaged.
Therefore, to prevent moisture from entering the oil, install caps immediately after using compressor oil or removing A/C components.
