Caution on piping
DANGER
Be sure to observe the following precautions while install-
ing piping. Improper piping may result in gas leakage.
If the leaking gas contains a toxic component, serious ac-
cidents may result. If it contains combustible gases, explo-
sion 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.
Caution on wiring
CAUTION
• 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 use
DANGER
• Be sure to read the instruction manual for reference gases
before handling reference gases such as calibration gas to
use them properly.
CAUTION
• 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.
PROHIBITION
• Do not touch the input/output terminals with metal or finger.
Otherwise, electric shock or injury may result.
• Do not smoke or use flames near the analyzer. Otherwise, fire
may result.
• Do not allow water to enter the analyzer. Otherwise, electric
shock or internal fire may result.
