SECTION 6
– INSTALLING THE HRU IN A SeaShelter™
BRACKET
The ACR
SeaShelter™ is a discontinued
product that looks like this:
Contents of the HydroFix™ HRU Kit that you will need:
HydroFix
™ Replacement Hydrostatic Release Unit (E)
SeaShelter
™ release rod (A)
Keyed bracket adapter (D)
Large cotter pin (H)
HRU expiration label (K)
Tools required: Flat-head screwdriver
Instructions:
1.) Remove the front cover and
carefully release the EPIRB
from the bracket. If the front
cover of the SeaShelter
™
contains a metal bushing
where the HRU rod is secured
close (see Figure A), use a
flat-head screwdriver and pry
the bushing out of the top case and discard. This bushing prevents
the HRU rod from securing to the cotter pin.
2.) Remove the old HRU unit and rod from the bracket by pressing the
spring release back and sliding the old HRU up and out of the
bracket.
3.) Take SeaShelter
™ release rod (A) and place it on top of the rod on
the HRU aligning the two sets of holes on the base (see Figure B).
4.) Place large cotter pin (H) inside the two holes, securing the two rods
together.
