- 16 -
Do not install the gas detector in a place exposed to water, oil or
chemicals.
When selecting installation points, avoid a place where the gas detector
is exposed to water, oil or chemicals.
Do not install the gas detector in a place where the temperature drops
below 20ºC or rises over 40ºC.
The operating temperature of the gas detector is 20 to 40ºC. The gas
detector must be installed in a stable place where the operating
temperatures are maintained and do not change suddenly.
Do not install the gas detector in a place exposed to direct sunlight or
sudden changes in the temperature.
Avoid a place where the gas detector is exposed to direct sunlight or
radiant heat (infrared rays emitted from a high-temperature object), and
where the unit temperature changes suddenly. Condensation may be
formed inside the gas detector, or the gas detector cannot adjust to
sudden changes in the temperature.
Keep the gas detector (and its cables) away from noise source devices.
When selecting installation points, avoid a place where
high-frequency/high-voltage devices exist.
Do not install the gas detector in a place where maintenance of the gas detector cannot be performed or
where handling the detector involves dangers.
Regular maintenance of the gas detector must be performed.
Do not install the gas detector in a place where the machinery must be stopped when maintenance is
performed in its inside, where parts of the machinery must be removed to perform maintenance, or where
the gas detector cannot be removed because tubes or racks, etc. prevent access to it. Do not install the
gas detector in a place where maintenance involves dangers, for example, near a high-voltage cable.
Do not install the gas detector in machinery which is not properly grounded.
Before installing the gas detector in machinery, the machinery must be grounded properly.
Do not install the gas detector in a place where interference gases exist around it.
The gas detector must not be installed in a place where interference gases exist around it.
