2-3. Precautions
CAUTION
Do not use the gas detector where it is exposed to oil, chemicals, etc. Do not submerge the gas
detector under water on purpose.
Do not use in a place where the gas detector is exposed to liquids such as oil and chemicals.
The gas detector, being compliant to IP67, is not water-pressure-resistant. Do not use the gas
detector where a high water pressure is applied to it (under a faucet, shower, etc.) or submerge
it under water for a long time. The gas detector is water-proof only in fresh water and running
water, and not in hot water, salt water, detergent, chemicals, human sweat, etc.
The gas inlet and outlet are not water-proof. Be careful not to let water such as rainwater get
into these parts. Because this may cause trouble and gas cannot be detected.
Do not place the gas detector where water or dirt gets accumulated. The gas detector placed at
such a location may cause malfunction due to water or dirt that gets into the buzzer opening,
etc.
Note that drawing in dirty water, dust, metallic powder, etc. will significantly deteriorate the
sensor sensitivities. Be careful when the gas detector is used in an environment where these
elements exist.
Do not use the gas detector in a place where the temperature drops below -20ºC or rises over 50ºC.
The operating temperature of the gas detector is -20 to 50ºC. Do not use the gas detector at
higher temperatures, humidities, and pressures or at lower temperatures than the operating
range.
Avoid long-term use of the gas detector in a place where it is exposed to direct sunlight.
Do not store the gas detector in a sun-heated car.
Observe the operating restrictions to prevent condensation inside the gas detector or gas sampling
hose.
Condensation formed inside the gas detector or gas sampling hose causes clogging or gas
adsorption, which may disturb accurate gas detection. Thus, condensation must be avoided. In
addition to the operating environment, carefully monitor the temperature/humidity of the sampling
point to prevent condensation inside the gas detector or gas sampling hose. Please observe the
operating restrictions.
Do not use a transceiver near the gas detector.
Radio wave from a transceiver near the gas detector may disturb readings. If a transceiver is
used, it must be used in a place where it disturbs nothing.
Do not use the gas detector near a device that emits strong electromagnetic waves
(high-frequency or high-voltage devices).
Verify that the pump driving indicator is rotating before using the gas detector.
If the pump driving indicator is not rotating, gas detection cannot be performed properly. Check
whether the flow rate is lost.
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 detector without performing a maintenance will compromise the sensitivity of the sensor, thus
resulting in inaccurate gas detection.
