General Safety Regulations For Refrigerants
CAUTION:
Extreme heating of air-conditioning system e.g. from sunlight shining into the vehicle or as a result of welding and soldering work.
- Danger of fire due to excessive heating of air conditioning.
- Danger of environmental pollution due to emerging refrigerant.
- → When carrying out repairs on the air-conditioning system, the system must be emptied by suction and the refrigerant must be purified. Chlorine-free refrigerants must also not be allowed to escape into the atmosphere and must be disposed of correctly.
- → Due to their chemical composition, different refrigerants must not be mixed with each other! This also applies for smaller quantities.
- → No welding, soldering or hot-air heating may take place on parts of the filled air-conditioning system or in its immediate vicinity.
- → While drying after painting work, the temperature burden on the vehicle must not exceed two hours at a maximum temperature of 80°C.
- → Whether or not the system is filled with refrigerant, the heating causes a very strong overpressure which can cause damage to the system or even lead to an explosion.
- → R 134a is completely non-toxic at normal temperatures, but it decomposes upon contact with a flame or at high temperatures.
- → Refrigerant bottles must not be thrown and must not be subjected to direct sunlight or other heat sources for an extended period when full.
- → The maximum permissible temperature of a filled refrigerant bottle must not exceed 45°C.
- → Risk of injury! High temperatures from open flames or hot solids causes chemical breakdown of refrigerant gas.
Inhalation of the resulting breakdown products leads to coughing and nausea.
WARNING:
Caustic fluids
- Danger of chemical burns
- → Wear personal protective gear.
- → Ensure that there is good ventilation.
- → Avoid contact with caustic fluid.
- → If you do come into contact, wash off immediately with plenty of warm water and contact a doctor if necessary.
WARNING:
Refrigerant
- Danger of freezing
- → Avoid contact with refrigerant.
- → Wear personal protective gear.
- → Observe the safety regulations for working on air-conditioned vehicles and handling refrigerant.
- → Observe the safety regulations for extraction and filling systems.
- → Observe the instructions for repairing air-conditioning systems and storing spare parts.
Information
- The following safety measures must be followed for refrigerant R134a and R1234yf (additional regulations may apply in certain countries).
- If repair work necessitates opening the refrigerant circuit, the refrigerant circuit must first be emptied. Avoid all contact with liquid or gaseous refrigerants. If refrigerant should escape despite all safety measures having been taken, do not inhale the resulting refrigerant/air mixture. Switch on extraction systems, protect hands with rubber gloves and protect eyes with protective goggles.
- If refrigerant gets onto any other body parts despite all safety measures having been taken, these should also be rinsed Immediately and thoroughly with water for at least 15 minutes.
- Smoking, welding, soldering and hard-soldering is prohibited in a room containing refrigerant.
- Read the relevant safety data sheet for handling refrigerant R134a and R1234yf.
- The air-conditioning system is pressurised when tilled and must not be opened in this state.
- Used or damaged condensers and evaporators must be marked before disposing of them in order to rule out any possibility of them being re-used.
If repair work necessitates opening the refrigerant circuit, the refrigerant circuit must first be emptied. Avoid all contact with liquid or gaseous refrigerants. If refrige art should escape despite all safety measures having been taken, do not inhale the resulting refrigerant/air mixture. Switch on extraction systems, protect hands with rubber gloves and protect eyes with protective goggles. If refrigerant gets onto any other body parts despte all safety measures having been taken, these should also be rinsed immediately and thoroughly witl wa' er for at least 15 minutes.
Although refrigerant R134a is non-flammable, smoking, welding, soldering and hard-soldering is prohibited in a room containing refrigerant.
