The lid will lift away from the top of the base and disengage at the bottom of
the base. The lid is tethered to the base to help prevent loss. Pull the
beacon with steady pressure from the bracket. It is not necessary to remove
the HydroFix™ Hydrostatic Release Unit (HRU) to mount the bracket using
four of the holes. For extreme conditions a fifth hole is available when the
HydroFix is removed and the ejector spring is deployed. The bracket can be
held in place to mark the placement of the screw holes or you can use the
mounting template provided. The use of #10 pan head stainless steel
fasteners (minimum of ½" long) and ½" washers (not included) is
recommended. Make sure that fasteners will not contact any wires or
plumbing before drilling pilot holes.
