Mounting
Fitting the AIS unit
Note: To ensure water resistance the unit must be mounted
vertically with the connectors facing down.
Note: If you are fitting the AIS unit to fiberglass that has a gelcoat
surface, overdrill the surface to prevent the gelcoat from damage
when securing the screws. Before drilling the pilot holes, hand
drill the marked locations with an oversized bit and countersink
to approximately 9.5mm (3/8in) diameter.
1. Ensure that the intended installation site meets the conditions
described under Site requirements.
2. Using a pencil, offer up the unit and mark the location of the
screw holes on the mounting surface.
3. Drill the mounting holes using a 3.2 mm (1/8") drill bit.
