The Category I float-free mounting bracket should be mounted securely to a vertical or horizontal surface (the mount
has predrilled holes for attachment to a flat surface) where there are no overhead obstructions. Location aboard a
vessel must be chosen to allow the beacon to float free of sinking craft and as high as possible, especially on small
vessels. This will help ensure operation of the hydrostatic release unit in the event the vessel capsizes without sinking.
See section 4.3 on removing the HRU.
The Category I float-free mounting bracket should be securely attached to the vessel. The use of #10 stainless steel
hardware (not included) is recommended.
4.2 Visual Inspection
Visually inspect the area surrounding the mounting bracket installation site for hidden hazards, obstacles, etc., that
may have been overlooked during location selection. If there is any doubt as to the ready accessibility to the beacon at
all times or if any condition may appear to be questionable, make a complete and thorough investigation before making
final approval of the installation.
4.3 Hydrostatic Release Unit (HRU)
The ACR HydroFix™ HRU has an expiration date of 2 years from the date of installation or 4 years from the date
manufactured, whichever comes first. Upon installing your beacon or new HRU, permanently scratch the new
expiration date on the HRU date calendar (as seen below).
Figure 1 HRU Date Calendar
The hydrostatic release can be replaced by removing the beacon from the bracket. Firmly press down on the spring at
the bottom of the shelter, then slide the hydrostatic release assembly out of the keyed opening on the spring and
mounting bracket. Discard the old HRU. Check the date manufactured on the bottom of the new HRU and insert the
new hydrostatic release assembly in place by engaging it to the opening of the ejection spring and case. When
replacing the HRU, ACR requires that you do not reuse any parts from the previous HRU. Failure to replace the
entire assembly can cause the bracket to malfunction. Always use original ACR replacement parts (Replacement kit
P/N #9490). Use of unauthorized replacement parts will void your warranty and may cause the bracket to malfunction.
Place the beacon into the mounting bracket, (lanyard facing inward), and replace cover, securing in place with the
cotter pin going through the hydrostatic release rod.
