when exposed to an open flame, R404A creates Phosgene gas, hazardous
in large amounts.
2. Always recover the refrigerant and store it in a proper container, if required
by an applicable law. Do not discharge the refrigerant into the atmosphere.
3. Do not use silver alloy or copper alloy containing Arsenic.
4. In its liquid state, the refrigerant can cause frostbite because of the low
temperature.
