Flush Mounting the Fishfi nder 320C Unit
The Fishfi nder 320C can be fl ush mounted on a fl at panel. When fl ush mounting the Fishfi nder 320C,
be sure to choose an appropriately sized location for the unit. Check that all cables will reach the unit
mounting location before beginning installation. Use the Flush Mount Template provided in the box to
determine a location. Be sure to always wear safety goggles and a dust mask when drilling, cutting or sand-
ing. Included Mounting Hardware: 4 - 3mm Studs, 4 - Flat Washers, 8 - 3mm Hex Nuts
To fl ush mount the Fishfi nder 320C:
1. Trim the Flush Mount Template and tape in the desired location.
2. Using a Center Punch, indent the center of each Mounting Hole location.
3. Using an 1/8" (3mm) drill bit, drill the four Mounting Holes.
4. Using a 3/8" (6mm) drill bit, drill a hole for a location to begin cutting the mounting surface.
5. Using the Jig Saw, cut the mounting surface along the inside of the dashed line indicated on the
template. Be very careful when cutting this hole, there is only a small amount of clearance
between the unit and the Mounting Holes. It may be prudent to cut slightly inside the indicated
line and then sand or fi le the panel as needed to obtain the best fi t.
6. Install the four Mounting Studs into unit by screwing the shorter section in to the back of the unit. Use a
1/16" (2mm) Allen Wrench to tighten the Mounting Studs until the stop contacts the case. Be careful not
to overtighten as this may damage the Mounting Stud! The studs have a reusable thread-locking patch
pre-applied from the factory.
7. Place the unit in position in the cut out in the mounting surface.
8. Place washers over the Mounting Studs, then thread on one Hex Nut per Mounting Stud. Tighten all four
until the unit is snug against the mounting surface. Install and tighten the second Hex Nut on all four
Mounting Studs to lock the fi rst one in place.
