3.4 Installing Scanner Unit _________________________________

Use a mounting base such as the ones shown in Fig. 3.3, 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.

Fig.3-3 Mount base

Use the template provided with this manual to drill five holes for mounting the scanner. At-

tach 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 Tab.3-6. Use a silicone sealant to prevent the bolts from working

loose. The housing may be damaged if you use a thread-locking compound.
