WARNINGS WHEN USING HYDROGEN
When hydrogen gas is in use, care should be exercised in order to prevent an
accident.
1.Connect gas lines correctly. Do not connect the hydrogen line to the air inlet, or
hydrogen will leak excessively.
To prevent an improper connection, the GC-2010 Plus is equipped with a right-handed
thread at the air inlet joint and a left-handed thread at the hydrogen inlet joint.
2.When the device is not in use, the main valve of the hydrogen gas cylinder or
generator must be closed. Also, make sure that there is no gas leakage from
the main valve of the supply.
3.The flow line for hydrogen gas should be checked for leakage whenever it is used.
4.To prevent buildup of explosive concentrations in case the hydrogen gas leaks,
the room in which the device is used should be well ventilated.
5.When analysis is complete, close the main valve of the hydrogen gas container
immediately before performing other procedures.
