Caution on piping
Be sure to observe the following precautions while installing
piping. Improper piping may result in gas leakage.
If the leaking gas contains a toxic component, serious acci-
dents may result. If it contains combustible gases, explosion
or fire may result.
• Connect pipes correctly referring to the instruction manual.
• Discharge the exhaust gas outdoors to prevent it from remain-
ing within the sampling device or indoors.
• Relieve the exhaust gas from the analyzer to the atmospheric
pressure to prevent buildup of undesirable pressure to the ana-
lyzer. Otherwise, piping within the analyzer may be discon-
nected, resulting in gas leakage.
• Use pipes and pressure reducing valves to which no oil/grease
is attached to the piping. Otherwise, fire may result.
Caution on wiring
• Be sure to turn off the power before installing wiring. Other-
wise, electric shock may result.
• Be sure to perform protective earth connection. Otherwise,
electric shock or failure may result.
• Select a proper wiring material that satisfies the ratings of the
instrument. Otherwise, electric shock or fire may result.
• Be sure to connect a power supply of correct rating. Other-
wise, fire may result.
CAUTION
DANGER
Caution on use
• Be sure to read the instruction manual for reference gases be-
fore handling reference gases such as calibration gas to use them
properly.
• Leaving the analyzer unused for a long time or restarting it
after long-term suspension requires procedures different from
normal operation or suspension procedures. Be sure to follow
the instructions in each instruction manual. Otherwise, intended
performance may not be achieved. Besides, accidents or injury
may result.
• Do not operate the analyzer for a long time with its door left
open. Otherwise, dust, foreign matter, etc. may stick on internal
walls, thereby causing faults.
