The air conditioning system must be filled with a safety refrigerant (Frigen 12).
Although this refrigerant is non-toxic, non-flammable and non-explosive in any mixture
ratio with air at normal temperatures, it can still be dangerous unless the appropriate
safety precautions are observed.
Avoid any contact with liquid or gaseous refrigerant. When working on the refrigerant
circuit of an air conditioner protect hands with gloves and eyes with goggles.
Refrigerant on the skin will cause frostbite.
Wash off pertinent parts of the body with cold water thoroughly. If refrigerant gets in
the eyes, also rinse out with water and the contact a physician immediately.
Frigen is heavier than air and therefore should not be discharged in closed rooms.
Especially in working pits there would be an acute danger of asphyxiation, which
would not be noticeable since the gas has no color or odor.
Turn on available air extraction systems.
Never perform welding wotk on a discharged air conditioner or in the vicinity. The
pressure which would occur could lead to an explosion.
In addition Frigen decomposes at high temperatures or when exposed to an open
flame. The decomposed products are injurious to health.
Store full refrigerant cylinders that they are not subjected to direct sunshine or other
sources of heat (max. temperature 45 ° C / 113° F).
