<Precautions>
CAUTION
Do not use a transceiver (walkie-talkie) near the detector.
Radio wave from a transceiver near the detector or its cables may disturb commands. when using a transceiver, it
must be used in a place where it disturbs nothing.
To restart the detector, you must wait five seconds more before doing it.
Restarting the detector within five seconds may cause errors.
Verify that the reading on the flow rate indicator corresponds to the specified flow rate before using the
detector.
If it does not correspond to the specified flow rate, gas detection cannot be performed properly. Check whether
the flow rate is unstable or lost.
Attach the dust filter before using the detector.
Before using the detector, attach the specified filter to prevent disturbances by possible gas adsorption or air dust.
A dust filter to be used is varies depending on the gas to be detected. For more information on dust filters, please
contact our sales department.
Observe the operating restrictions to prevent condensation inside the tube.
Condensation formed inside the tube causes clogging or gas adsorption, which disturb accurate gas detection.
Thus, condensation must be avoided. In addition to the installation environment, carefully monitor the
temperature/humidity of the sampling point to prevent condensation inside the tube. In particular, when detecting
a gas which is solved into water and corrodes contacted materials, such as a strong acid gas, the gas is
undetectable and furthermore may corrode internal parts. Please observe the operating restrictions.
Do not use the external output of the detector to control other devices.
This is not a control device. You are not allowed to use its external output to control other devices.
Do not disassemble/modify the detector, or change the settings if not necessary.
Disassembling/Modifying the detector will invalidate the guarantee of the performance. Changing the settings
without understanding the specifications may cause alarm malfunctions. Please use the detector properly in
accordance with the operating manual.
Do not forget to perform a regular maintenance.
Since this is a safety device, a regular maintenance must be performed to ensure its safety. Continuing to use the
detector without performing a maintenance will compromise the sensitivity of the sensor, thus resulting in
inaccurate gas detection.
