3 Installation

3.1 Siting

The placement of gas detectors should be determined following the advice of:
• experts having specialist knowledge of gas dispersion
• experts having knowledge of the process plant system and equipment involved
• safety personnel
• engineering personnel
The agreement reached on the location of detectors should be recorded.
Guidance on the positioning of gas detectors to provide the best detection coverage is contained in
IEC/EN 60079-29-2 and other national Codes of Practice. It is recommended that the installation de-
signer consults these Codes of Practice when determining where detectors are to be located.

3.2 Mechanical Installation

The OELD can be mounted in a number of ways using the integral mounting tabs. The OELD can be
attached to flat wall surfaces or to Unistrut®. With the optional Pipe Mount kit, the unit can be mount-
ed to pipe of diameter 2" to 6" (50 to 150mm). A ceiling mount bracket kit (1226A0358) is also availa-
ble.

3.2.1 Installation to a Flat Surface

OELD may be fixed directly to a suitable flat surface, using the integral mounting points (dimensions
shown below).
Note: When installing OELD ensure that the correct sensor orientation is considered. Refer to the
sensor manufacturer's instructions.
Ensure that mounting bolts are fully tightened and suitable locking washers are used.
