How to Use
4-1. Before using the detector head
Not only the first-time users but also the users who have already used the detector head never fail to follow
the operating precautions.
Ignoring the precautions may damage the detector head, resulting in inaccurate gas detection.
4-2. Precautions for installation sites
CAUTION
This is a precision device. Because the detector head may not provide the specified performance
in some places (environments), check the environment in the installation point, and then take
appropriate actions if necessary.
Because the detector head plays an important role for safety and disaster prevention, as many
units of the detector head as needed must be installed in appropriate points.
Because points where gases leak and remain easily are different depending on the types of
gases and the working areas, please decide carefully on installation points and the number of
units to be installed.
Do not install the detector in a place with vibrations or shocks.
The detector head consists of sensitive electronic parts. The detector must be installed in a stable place
without vibrations or shocks and it cannot drop.
Do not install the detector head in a place exposed to direct sunlight or sudden changes in the temperature.
When selecting installation points, avoid a place where it is exposed to direct sunlight or radiant heat
(infrared rays emitted from a high-temperature object), and where the temperature changes suddenly.
Condensation may be formed inside the detector head, or the detector head cannot adjust to sudden
changes in the temperature.
Keep the detector head (and its cables) away from noise source devices.
When selecting installation points, avoid a place where high-frequency/high-voltage devices exist.
Do not place the detector head next to a noise source device.
Do not run cables in parallel or close to each other.
Do not install the detector head in a place where maintenance of the detector cannot be performed or where
handling the detector involves dangers.
Regular maintenance of the detector head must be performed.
Do not install the detector head 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 detector head cannot be removed because tubes or racks, etc. prevent access to it.
Do not install the detector head in a place where maintenance involves dangers, for example, near a high-
voltage cable.
