Which EPIRBs does this HRU kit fit?
The SmartFind G8 PLUS AIS user manual specifies McMurdo HRU Replacement Kit 23-145A for the float-free auto-housing, so it is the correct kit for the G8 PLUS AIS Auto (23-002-501A). The fitting guide also lists McMurdo SmartFind E8 Auto, G8 Auto and G8 AIS Auto, Kannad Safe / SafePro Auto, and Sailor 4065 Auto models. It is not used on the Manual Category 2 bracket version.
How often should it be replaced?
Mark the HRU with an expiry date of 2 years from the date of installation, as set out in the official fitting guide. The G8 PLUS user manual likewise describes a typical 2-year replacement interval. The kit is for single use; if it has been activated or damaged, replace it immediately.
Can I service the HRU myself beyond fitting the kit?
The fitting guide says not to dismantle the HRU and that it contains no user-serviceable parts. Follow the official fitting guide when installing the replacement kit, and copy the new expiry date onto the enclosure label.
