8.6 Securing the Radome Scanner to the Mounting Surface

CAUTION:
The drain tube must always be used, but may be shortened if necessary
Note: Using the paper template supplied with the scanner mounting kit, mark
the flat mounting surface with the mounting holes and drain tube hole, and
drill the holes as indicated on the template.
If it is impractical to drill a hole for the drain tube, then the scanner unit should
be mounted on 4 suitable spacers 10 mm high and the drain tube length re-
duced by 10 mm. It will then be clear of the flat surface and can still perform its
function.
Note: If you are using a Raymarine mast mount bracket, the surface is pre-
prepared.
Note: If you are mounting the scanner on a flat surface, you may find it easier
to fit the drain tube, as described in the following section, before securing the
scanner.
1. Position the scanner on the mounting surface, ensuring that the cable inlet
is pointing aft.
2. Locate the bolts and washers supplied with the scanner, grease the bolts,
and secure the scanner to the mounting surface as shown in the following
diagram. Tighten the bolts to 20 Nm (14.7 lb ft); ensure the scanner is
tightly fitted.

You may need to use longer M8 mounting bolts to secure the scanner if
you have used shims to lower the radar beam.
