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,
etc. 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 measurement. 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 or
other radio wave transmitting device 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 flow check display is not rotating, gas detection cannot be performed properly. Check
whether the flow rate is lost.
WARNING
Others
•
Do not throw the gas detector into fire.
•
Do not wash the gas detector in a washing machine or ultrasonic cleaner.
•
Do not block the buzzer sound opening. No alarm sound can be heard.
•
Do not remove the battery while the power is on.
•
Be sure to connect the gas sampling probe to the gas detector and check that the
surrounding air is fresh before turning on the power.
•
If the main unit is dropped or given a shock, the reading may rise and it may remain so. In
such a case, perform air calibration in a place where the surrounding air is fresh.
