3. Installation Method
3.1 Determine the installation location for the sensor case
Ensure that you adhere to the following points.
(1) Ensure clear space around the case as shown in the figure on the right, regardless of whether it is
installed using a switch box or on a wall.
(2) Source the following items locally.
- Putty
<Extra items required if installing using a switch box>
- Single-gang switch box
- Thin steel conduit
- Lock nut and bushing
Note:
- Direct sunlight sometimes cause the sensor case to discolor. Please be careful when
deciding the install position.
- Determine the sensor installation location only after checking with local laws and
regulations.
- Ensure that no objects are placed in the clear space around the sensor case to detect the
correct CO
concentrations.
2
- Ensure a flat surface is selected for the installation surface.
