2. BRAZING

WARNING

1.Refrigerant R22 itself is not flammable, explosive or poisonous. How- ever, when exposed to an open flame, R22 creates Phosgene gas, hazardous in large amounts.

2.Always recover the refrigerant and store it in an approved container. Do not discharge the refrigerant into the atmosphere.

3.Do not use silver alloy or copper alloy containing Arsenic.

Note: All brazing-connections in the Evaporator Case are clear-paint coated. Sandpaper the brazing-connections before unbrazing the components. Use a good abrasive cloth to remove paint.
