Precautions to be taken while checking

1. When handling reference gas (during calibration), carefully read the reference-gas instruc-

tion manual to use the gas correcrtly. In particular, special attention must be taken in han-
dling carbon monoxide gases; otherwise, you may suffer from gas poison-ing.

2. During maintenance checks, be sure to keep the near fan on. If any gas leaks, you may suffer
from gas poisoning.

3. When replacing the analyzer gas filter or conducting maintenance service of the washer,

completely shut the calibration-gas valve. Otherwise, you may suffer from gas poisoning.
