Surface Mounting the Compass
Before you mount the compass, you must review the mounting location considerations and select a mounting
location.
NOTE: The supplied M4 x .07 x 45 threaded rods can be used on mounting thicknesses of 5 to 30 mm (
3
/
16
to
1
3
/
16
in.) (recommended). For surfaces over 30 mm (1
3
/
16
in.), you must use longer threaded rods (not
included).
1 Secure the included mounting template to the selected mounting location.
2 Drill the three 5 mm (
3
/
16
in.) screw holes.
3 Drill the 25 mm (1 in.) cable hole in the center.
4 Install the included gasket on the bottom of the compass.
5 Route the cable through the center hole, and connect it to the compass.
6 Insert the three threaded rods into the mounting holes on the bottom of the compass.
Up to 35 mm (1
3
/
8
in.) of the threaded rods may extend below the compass.
7 Place the compass on the surface, feeding the threaded rods through the holes you drilled previously.
8 Apply a bead of marine sealant on the mounting surface around each mounting hole.
9 Fasten the compass to the mounting surface using the threaded rods , flat washers , spring
washers
, and hex nuts .
10 Using a torque wrench, tighten the nuts to 13.7 to 18.6 N-m (10 to 14 lbf-ft.).
11 Route the cable away from sources of electronic interference.
Mounting the Compass on a Pole
Using the included pole-mount adapter, this device can be installed on a standard 1 in. OD, 14 threads per inch,
pipe-threaded stainless steel pole (not included). The cable can be routed inside or outside of the pole.
NOTE: This device is designed for use with a stainless steel pole. Mounting the device on a plastic pole can
result in unintentional rotation that may affect the heading information.
