2-3. Precautions
CAUTION
Do not use a transceiver near the gas detector.
Radio wave from a transceiver etc. near the gas detector or its cables may disturb indication reading. If
a transceiver or other radio wave transmitting device is used, it must be used in a place where it
disturbs nothing.
To restart the gas detector, wait for five seconds or more before doing it.
Restarting the gas detector in less than 5 seconds may cause errors.
Verify that the reading on the flow rate indicator corresponds to the specified flow rate before using the
gas 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 provided filter before using the gas detector.
Before using the gas detector, attach the specified filter to prevent disturbances by possible gas
adsorption or air dust.
A filter to be used varies depending on the gas to be detected. For more information on filters, please
contact RIKEN KEIKI.
Also, the gas detector itself is not dust-proof. Take an appropriate measure such as attaching a
protective cover when the gas detector is used in a dusty environment.
Observe the operating restrictions to prevent condensation inside the tube.
Condensation formed inside the tube causes clogging or gas adsorption, which may 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 dissolved 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 gas detector to control other units.
This is not a control unit. It is not allowed to use the external output of the gas detector to control other
units.
Do not disassemble/modify the gas detector, or change the settings if not necessary.
Disassembling/modifying the gas detector will invalidate the warranty of the performance. Changing the
settings without understanding the specifications may cause alarm malfunctions. Please use the gas
detector properly in accordance with the operating manual.
Never fail to perform a regular maintenance.
Since this is a safety unit, a regular maintenance must be performed to ensure safety. Continuing to use
the gas detector without performing a maintenance will compromise the sensitivity of the sensor, thus
resulting in inaccurate gas detection.
Do not install in places where equipment cannot be operated.
Do not install the unit in a place where it is difficult to operate so that it can be operated easily in case of
emergency power-off and our maintenance equipment.
