2. Use goggles to protect your eyes and gloves to protect your hands. If refrigerant gets into your eyes, rinse them with water immediately.

3. The container with refrigerant R-134a is under high pressure. It is prohibited to store the container in places where it can be exposed to high temperatures. The storage temperature should not exceed 52°C.
4. Check the tightness of the system with an electronic leak detector. It should be remembered that the refrigerant R-134a, when exposed to an open flame, releases highly toxic phosgene gas.
5. Use only the specified oil to fill the R-134a refrigerant circuit. Using other oils may cause the system to fail.
6. Since PAG oil intensively absorbs moisture from the surrounding air, the following precautions should be taken:
- When removing any parts of the refrigeration circuit, immediately plug the openings to protect against moisture ingress.
- When installing refrigeration circuit components, remove the hole plugs immediately before installing the components.
- Connect all pipes and hoses as quickly as possible to prevent moisture from entering the air conditioning system.
- Use only the specified grade of compressor oil from a sealed container.
7. If refrigerant accidentally leaks from the system, ventilate the work area before continuing work.
