7.5 Fastening the mounting bracket
Warning: Ensure there are no electrical wires or plumbing behind the selected mounting position before
drilling. Ensure the mounting surface is flat.
Fasten the mounting bracket to the surface. Ensure the detector is correctly positioned, level and that the
hooks point upwards (see Figure 7-2).

7.6 Mounting the Detector onto the Bracket
In order to prevent the detector being removed from the bracket once installed an anti-tamper screw is
provided (refer to Figure 2-2). This screw locks the detector onto the bracket. Before sliding the detector onto
the mounting bracket, ensure that the anti tamper screw is fully screwed out. Only tighten the anti-tamper
screw once the detector is in place.
Insert the sampling pipe into the inlet port ensuring a firm fit and where relevant connect the exhaust pipe. Fit
appropriate conduit or cable clamps as required.
7.7 Connecting the air sampling pipe
The air inlet port is designed to fit a standard pipe of 25mm OD. The air inlet port is tapered to provide a
positive seal.
Note: Where ¾" pipe, which has an 11/16" OD, is used then a suitable adaptor should be used to connect
the pipe to the inlet manifold.
To connect the sampling pipe:
1. De-burr and square off the end of the sampling air pipe. Ensure the pipe is free from swarf.
2. Remove the plugs from the inlet and exhaust ports.
3. Insert the pipe into the inlet port ensuring a firm fit. DO NOT glue this connection.
4. Pipe the exhaust when necessary.
Caution: DO NOT GLUE THE AIR INLET AND EXHAUST PIPE CONNECTION. A glued connection
makes disconnecting the sampling air pipe from the detector for maintenance extremely difficult
and may result in damage to the equipment.
Note: It is essential to remove the exhaust shipping Plug from the exhaust port and this is best done when
the inlet pipe is inserted.
