Caution on use
• Be sure to read the instruction manual for reference gases before
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, or 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.
Caution on wiring
• Be sure to turn off the power before installing wiring.
Otherwise electric shock may result.
• Be sure to perform class D grounding work. 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.
Otherwise, fire may result.
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
accidents 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
remaining 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
analyzer. Otherwise piping within the analyzer may be
disconnected, resulting in gas leakage.
• Use pipes and pressure reducing valves to which no oil/grease
is attached for piping. Otherwise, fire may result.
