EPIRB including new HRU: August 1, 2007.

Scratch off “AUG 8” and “2006” on the HRU date calendar
Date of Manufacture Example:
On the bottom of the HRU a date of manufacture is pin
stamped: 0806.
This unit will need to be replaced in 0809. Scratch off “AUG

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 as-
sembly 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 previ-
ous HRU. Failure to replace the entire assembly can cause the bracket to malfunction. Al-
ways 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.
