4-4. How to install
A certain maintenance space needs to be secured in advance to allow the maintenance personnel to
safely and properly perform maintenance of the gas detector function and performance. Be sure to secure
this space during construction planning or installation.
(1) Mount the main unit on the wall.
(2) Insert screws to the upper and lower fixing holes of the main unit and tighten them. (Use M5 screws.)
Fixing hole (M5)
Leave the diagonal line area so that
the installation space is reserved.
CAUTION
Check that the main unit is mounted securely on the wall. If not, the main unit may fall off and cause
unexpected injury or damage to the unit.
Do not install the detector in a place where maintenance of the detector cannot be performed or where
handling the detector involves dangers.
Regular maintenance of the detector must be performed.
Do not install the 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 detector cannot be removed because tubes or racks, etc. prevent access to it.
Do not install the detector in a place where maintenance involves dangers, for example, near a high-
voltage cable.
