6.1 Check Procedure Before Installation

(a) Do not install your LaserSCANNER if there are any signs of shipping damage to the
product. Inform your distributor if there is any damage.
(b) Check the model of the LaserSCANNER is correct as per the design specifications for the
site. Refer to the model number located on the product and approvals label attached at the
bottom of the detector.
(c) Identify the location where the detector is to be mounted. The LaserSCANNER can be
mounted on a wall or a suitable secure surface. There are two allowable mounting positions
for the LaserSCANNER as shown in Figure 3.
•
Normal Orientation: Mounting the detector with the inlet air ports on the top right
hand side of the box and the exhaust air port at the bottom.
•
Inverted Orientation: Mounting the detector with the inlet air ports at the bottom
left hand side of the box and the exhaust air port on the top.
(d) Verify that the selected mounting location is suitable to fit the detector by test fitting the
LaserSCANNER onto the actual mounting position or use the drilling template supplied with
this manual. Ensure there is 150mm of clear space around the air inlet, exhaust and cable
entry ports to allow for pipe and cable entry.
(e) Verify that the cable entry points and the sampling air pipes are at its correct locations.
(f) Determine the type of fasteners required for attaching the mounting bracket onto the
mounting surface. The size of the mounting holes on the mounting bracket is 6mm
(15/64in).
