2.3 Installing the Detector
In all installation cases the mounting bracket must be fitted (upright) as shown in Figure 2-4 on page 8.
Note: Ensure the mounting surface is flat. This will permit an air tight seal to be achieved between the
sampling pipe and the tapered air ports on the detector.
Warning: Prior to drilling the attachment holes for the mounting bracket, ensure that all mounting surfaces
(i.e. walls, cabinet sides, etc.) are clear of electrical wiring and plumbing.
Where the pipe network and cabling are already fitted, the bracket can be used to aid alignment of the detector
with the pipes. The Installation procedure below explains this process.
