To remove the expired HydroFix HRU
When opening the lid of the Category 1 bracket, note that the beacon is installed with the buttons facing outward. Pull
the beacon with steady pressure from the bracket. Do not get beacon wet while it is out of the bracket. The HydroFix
HRU has a keying feature that locks it to the bracket. If you view the HydroFix HRU rod as the center of a clock, a
properly installed HydroFix HRU will rest at the 7 o'clock position, as shown in the left–hand picture below.
WARNING: The HydroFix HRU holds down an ejection spring. The spring must be firmly held in place during the
removal and installation of the HydroFix HRU to prevent injury.
Depress the top of the ejection spring. This will relieve pressure on the HydroFix HRU and allow it to be rotated
counterclockwise to the 5 o'clock position as shown in the right-hand picture above. The HydroFix HRU is now free to be
removed. Slowly relieve pressure from the ejection spring and allow it to deploy.
WARNING: Discard the expired HydroFix HRU. Failure to replace the entire assembly may cause the bracket to
malfunction.
WARNING: Be sure to use only ACR's HydroFix HRU (ACR P/N 9490.1) in the Category I bracket
replacement parts will void your warranty and may cause the bracket to malfunction.
Check the date of manufacture on the new HydroFix HRU. Follow the instructions that accompany the HydroFix HRU for
marking the next expiry date and for selecting the correct rod adapter
