Page 3: Safety Precaution
SAFETY PRECAUTION First of all, read this “Safety Precaution” carefully, and then use the analyzer in the correct way. • The cautionary descriptions listed here contain important information about safety, so they should always be observed. Those safety precautions are ranked 2 levels; “DANGER” and “CAUTION”. Meaning Warning &... - Page 4 Caution on piping DANGER: In piping, the following precautions should be observed. Wrong piping may cause gas leakage. If the leaking gas contains a toxic component, there is a risk of serious accident being induced. Also, if combustible gas is contained, there is a danger of explo- sion, fire or the like occurring.
- Page 5 Caution on maintenance and check DANGER: • When doors are open during maintenance or inspection for adjusting the optical system, etc., be sure to purge sufficiently the inside of the gas analyzer as well as the measuring gas line with nitrogen or air, in order to prevent poisoning, fire or explo- sion due to gas leaks.
