8.1 Warnings and Notices

8.1.1 Warnings and Notices

Warning!

Carry out the refrigerant related work in a well-ventilated
environment. Do not breathe refrigerant vapor. To avoid
inhalation of air-conditioning refrigerant R-134a (PTFE
oxide), and lubricant vapor or mist. Contact with them the
will stimulate the eyes, nose and throat. Operate in a
well-ventilated area. When removing R-134a from the
air-conditioning system, use certified maintenance
equipment (R-134a recycling equipment) that meets the
requirements. If the system accidentally discharges,
before continuing to repair, the work area must be
ventilated. Other relevant health and safety information
can be obtained from refrigerant and lubricant
manufacturers.

Warning!

Before servicing the electrical system, disconnect the
battery negative cable. It is prohibited to carry out
welding or steam cleaning operations near the vehicle
with air-conditioning pipelines or parts installed.

Air-conditioning refrigerant Notice

Note

–

Skin contact may cause frostbite.

–

Must comply with the instructions provided by the
manufacturer. During operation, wearing proper
goggles and protective gloves.

To avoid following air-conditioning refrigerant operations

Note

–

Do not store refrigerant under direct sunlight or near
a heat source.

–

During filling, do not place the refrigerant bottle
upright, keep the valves facing down.

–

Do not expose the refrigerant bottle to the frost or
snow.

–

Do not drop the refrigerant bottle.

–

Do not in any case, directly discharge the refrigerant
to the atmosphere.

–

Do not be mix refrigerants, such as R134a (PTFE
ethane) and R12 (2 fluoro-2 chlorinated methane).

Frozen Oil Notice

Note

Must use compressor manufacturers recommended
types and grades of lubricant. Do not mix different types
and grades of lubricant, otherwise it will damage the
compressor. Minimize lubricant contact with air, as it is
highly absorbent.

Note

Do not use water, corrosive or flammable and explosive
solvent to clean the air-conditioning system. It is
recommended to use R-141b, heptane and other
cleaning agents.
