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.
