Caution on piping
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
explosion, fire or the like occurring.
• Connect pipes correctly referring to the instruction manual.
• Exhaust should be led outdoors so that it will not remain in
the locker and installation room.
• Exhaust from the analyzer should be relieved in the atmo-
spheric air in order that an unnecessary pressure will not be
applied to the analyzer. Otherwise, any pipe in the analyzer
may be disconnected to cause gas leakage.
• For piping, use a pipe and a pressure reducing valve to which
oil and grease are not adhering. If such a material is adhering,
a fire or the like accident may be caused.
CAUTION
Caution on wiring
• Wiring work must be performed with the main power set to
OFF to prevent electric shocks.
• Enforce construction of class-D grounding wire by all means.
If the specified grounding construction is neglected, a shock
hazard or fault may be caused.
• Wires should be the proper one meeting the ratings of this
instrument. If using a wire which cannot endure the ratings, a
fire may occur.
• Be sure to use a power supply of correct rating. Connection of
power supply of incorrect rating may cause fire.
DANGER
Caution on use
• For correct handling of calibration gas or other reference gases,
carefully read their instruction manuals beforehand. Otherwise,
carbon monoxide or other hazardous gases may cause an intoxi-
cation particularly.
• Before leaving unused for a long time or restarting after left at
such a status for an extended length of time, follow the directions
of each instruction manual because they are different from
normal starting or shutdown. Otherwise, the performance may
be poor and accidents or injuries may be caused.
• 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.
