Mazda 6 Service Manual: Service warnings
HANDLING REFRIGERANT
- Avoid breathing air conditioning refrigerant or lubricant vapor.
Exposure may irritate eyes, nose and throat. Also, due to environmental
concerns, we urge use of recovery/recycling/recharging equipment when
draining R-134a from the air conditioning system. If accidental system
discharge occurs, ventilate work area before resuming service.
- Do not perform pressure test or leak test for R-134a service
equipment and/or vehicle air conditioning system using compressed air. Some
mixtures of air and R-134a have been shown to be combustible at elevated
pressures. These mixtures, if ignited, may cause injury or property damage.
Additional health and safety information may be obtained from refrigerant
manufacturers.
- Do not allow the refrigerant to leak near fire or any kind of heat. A
poisonous gas may be generated if the refrigerant gas contacts fire or heat
such as from cigarettes and heaters. When carrying out any operation that
can cause refrigerant leakage, extinguish or remove the above-mentioned heat
sources and maintain adequate ventilation.
- Handling liquid refrigerant is dangerous. A drop of it on the skin
can result in localized frostbite. When handling the refrigerant, wear
gloves and safety goggles. If refrigerant splashes into the eyes,
immediately wash them with clean water and consult a doctor.
STORING REFRIGERANT
- The refrigerant container is highly pressurized. If it is subjected
to high heat, it could explode,
scattering metal fragments and liquid refrigerant that can seriously injure
you. Store the refrigerant at temperatures below 40 °C {104 ° F}.
HANDLING INSUFFICIENT REFRIGERANT LEVEL
If an insufficient refrigerant level is detected at troubleshooting,
do not charge (add) the refrigerant. Because an accurate amount of
refrigerant ca ...
