risks. The operator must wear safety glasses, gloves and suitable clothing to work, contact with
refrigerant may cause blindness (eyes), and other physical damage (frostbite) to the operator.
Avoid contact with the skin, the low boiling temperature (about -26°C for R134a and about -
30°C for R1234yf ) can cause cold burns. Do not change the setting of the relevant devices for
safety, do not remove the seals of the safety valves and control systems. Do not use external
