How to Operate
5-1. Preparation for start-up
Before connecting a power supply, read and understand the following precautions. Ignoring these
precautions may cause an electric shock or damage the unit.
Connect the gas detector to a grounding circuit.
Check that the external wiring is done properly.
Check that the power voltage is compliant with the specification.
Because the external contact may be activated during the adjustment, take measures to prevent an
activated contact from having influences on external circuits.
Remove the protective rubber cap from GAS IN and GAS OUT. If the gas detector is turned on with the
rubber caps remaining while the installation, applied overload may damage the pump and sensor. Never
fail to remove the caps.
Check that there is no clogging or leak in the connected tube. (If the connected tube is clogged, pressure
is applied to the sensor unit, causing errors and malfunctions.)
Check that the filter is attached properly. (The filter is specified based on the gas to be detected.)
Make sure to use a fuse with the specified ratings to prevent fire.
Check that the gas detector is leveled. The gas detector must be installed in the right direction to ensure
its performance. (* The direction of the gas detector must also be kept during transportation, including
when it is removed temporarily or relocated.)
