Notes, Cautions and Warnings  
The following notes, cautions and warnings apply to all EPIRBs and  
must be followed for personal safety and proper HRU replacement.  
WARNING: Failure to replace the entire assembly can cause the  
bracket to malfunction.  
WARNING: Do not use any parts from the old HRU (the one being  
replaced).  
WARNING: The HRU holds down the ejector spring. Take great  
care to hold the spring in place during removal and installation of the  
new HRU to prevent injury.  
WARNING: Stow the EPIRB in a dry location as it will activate if out  
of the bracket and wet.  
WARNING: Non-ACR-supplied hydrostatic release units must not be  
installed in ACR Category I EPIRB brackets. ACR cannot and does not  
warrant the performance of other manufacturers’ products. Installation  
of a non-ACR-supplied HRU voids the warranty and potentially  
jeopardizes your safety.  
CAUTION: Visually check the EPIRB when removing it from the  
bracket. It must be sent back to ACR for check up and/or refurbishment  
if ANY of the following conditions exist:  
Cracks to the exterior plastics  
Activation indicator break tab is broken  
Moisture appears inside the EPIRB  
Lacquer is not present in one of the screws or appears to have been  
tampered with  
NOTE: Some parts in this kit will not be used. Refer to Figure 1 and the  
instructions for your specific model for details. Discard unused parts.

SECTION 3 HOW TO DETERMINE HRU EXPIRATION  
DATE  
The ACR HydroFixHRU is a replaceable part and, as such, has  
dating associated with it. The HRU must be replaced two (2) years  
from the install date or four (4) years from the date of manufacture,  
whichever is less.  
The HRU has a calendar on its top side; the calendar should be marked  
with the expiration date at the time of installation, according to the  
following instructions.  
Date of Installation Example:  
Date of installation of New HRU or  
first installation of EPIRB including  
new HRU: August 1, 2009.  
This unit will need to be replaced in  
August 2011.  
Mark off “AUG 8” and “2011” on the  
HRU date calendar  
Date of Manufacture Example:  
On the bottom of the HRU a date of  
manufacture is pin stamped: 0808.  
This unit will need to be replaced  
in August 2012.  
Mark off “AUG 8” and “2012” on the  
HRU date calendar
