v
Safety precautions
This section provides precautions for using the product safely and correctly and to prevent
injury and damage. The terms of DANGER, WARNING, and CAUTION indicate the degree of
imminency and hazardous situation. Read the precautions carefully as it contains important
safety messages.
WARNING
Fire
• When the analyzer will not be used, be sure to disconnect the power plug from the
outlet for safety.
• Remove any dust from the power plug regularly several times a year.
If the plug is left plugged in for a long period of time, electrical tracking may occur due to
dust or humidity, which may cause ignition or fire.
Electric shock and fire
• Do not use the analyzer while the power cord is bundled.
• Do not damage or apply an excessive force to the power cord by, for example, bending
or pulling it repeatedly or placing a heavy object on it.
• If the plug cannot be plugged into an electrical outlet firmly, stop use of the power
supply cord.
There is a risk of electric shock and failure. Furthermore, the above may cause
overheating and fire.
Electric shock
To prevent electric shock, be sure to connect a ground wire using the supplied cord set.
Toxic gas
Sample gas containing toxic gas is exhausted from the exhaust connector.
Connect an exhaust pipe to this connector and properly release the gas to a safe place
other than the measuring site.

Product Handling Information
Operational precautions
Use of the product in a manner not specified by the manufacturer may impair the protection
provided by the product. And it may also reduce product performance.
Exercise the following precautions.
General precautions
Do not disassemble or modify the analyzer, except as otherwise instructed in this manual.
Before turning on the power switch, check that the power voltage is appropriate.
Do not use the cord set (power cable) and other accessories with other than the
corresponding analyzer.
Carbon monoxide is highly toxic and so a high concentration of it entering the respiratory
system or even, for example, inhaling a low concentration (10 ppm or less) of it for a long
period of time is extremely dangerous. Strictly observe the following.
Check that there is no leak from the span gas line.
Connect all exhaust ports to exhausts which output to a safe outdoor location.
Adjustment of this analyzer was performed before shipment from the factory.
Do not change the settings, touch the switches, or otherwise touch the analyzer more
than necessary.
Operating precautions
This analyzer uses a high-pressure gas for calibration. When handling this analyzer, pay
attention to the following points.
Pay attention to ventilation.
Pay attention to the handling of the high-pressure gas.
Take the following safety measures when operating and maintaining the analyzer.
Do not perform disassembly and assembly work on the analyzer while the power is on.
In order to prevent electric shock and analyzer damage, disconnect the cord set (power
cable) and discharge the electrical energy from the internal circuits before performing
the work.
Pay attention to the handling of the high-pressure gas.
Attach and detach a pressure regulator properly. Secure the gas cylinder in place
properly.
Note
GA-370 does not have an explosion-proof construction. Even the special gas type specifications
are not explosion-proof, but just intended to reduce the risk of gas leaks. Take special care when
handling hazardous gases. We take no responsibility for any ignition, combustion, and explosion.
Precautions for moving
The weight of the main unit is approximately 18 kg. Observe the following when moving the
analyzer.
Do not subject the analyzer main unit to an impact.
Do not place the analyzer main unit on its side.
Use a cart or the like when moving the analyzer a long distance.
Do not move the analyzer while it is placed on another device or object.
When the analyzer is carried, the work must be performed by more than one person.

vii
Long-term storage
When the analyzer will not be used for a long period of time (one month or longer), store it in
accordance with the following.
If a span gas cylinder is connected, close the valve.
When storing the analyzer in a location other than the installation site, avoid a location
subject to direct sunlight, wind, and rain.
Do not cover the system with a vinyl cover because doing so will cause condensation to
form inside the analyzer, which will cause corrosion.
Disposal of the product
When disposing of the product, follow the related laws and/or regulations of your country.
