4.4.2.2 Installing the Scanner Unit
Use a mounting base such as the ones shown in Fig. 4.6, or you can install the scanner directly to a
roof or other flat surface. Be certain you keep the water drain tube clear. It's located at the bottom
of the scanner unit.
Note:
If the mounting bracket or surface has a curvature of more than 2mm, use spacers with the
mounting bolts to prevent stress on the scanner housing.
Use the template provided with this manual to drill five holes for mounting the scanner. Attach the four
bolts and feed the drain tube through the fifth hole. The bolts included with your unit will suffice for
mount base thickness of 9 to 14 mm (0.35 to 0.55 in.). If the mount base is thicker or thinner, refer to
Table 4.4.2. Use a silicone sealant to prevent the bolts from working loose. The housing may be
damaged if you use a thread-locking compound.
