To remove the expired HRU
When opening the SeaShelter
3
™ lid, note that the beacon is installed
with the lanyard face in. Pull the beacon with steady pressure from the
bracket. Do not get beacon wet while out of bracket. The HRU has a
keying feature that locks it to the bracket. If you view the HRU rod as the
center of a clock, a properly installed HRU will
rest at the 7 o’clock
position, as shown in the picture above.
WARNING: The HRU holds down an ejection spring. The spring
must be held in place during the removal and installation of the
HydroFix™ to prevent injury.
Depress the top of the ejection spring. This will relieve pressure on the
HRU and allow it to be rotated counter
clockwise to the 5 o’clock position.
The HRU is now free to be removed. Slowly relieve pressure from the
ejection spring and allow it to deploy.
WARNING: Discard the expired 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) in the SeaShelter
3
™. Use of unauthorized replacement parts will
void your warranty and may cause the bracket to malfunction.
Check the date of manufacture on the new HRU. Follow the instructions
that accompany the HydroFix™ for marking the next expiry date and for
selecting the correct rod adapter for the SeaShelter
3
™.
To install the new HRU
Apply pressure to the ejection spring and hold it flat against the bracket.
With your free hand place the new HRU into the key way in the 5 o’clock
position and rotate clockwise to the 7 o’clock position. Slowly remove
pressure from the ejection spring. The HRU should now be held in the 7
o’clock position with the pressure on the ejection spring.
Reinstall the beacon with lanyard face in. Beacon should fit snugly in the
bracket with the antenna captured by the bracket. Reinstall the lid by
seating the bottom of the lid to the detent on the base. Close the upper
portion of the lid so the HRU rod lines up with the spring loaded knob.
With gentle pressure, hold the lid while you turn the lock
counterclockwise until it stops, then clockwise until it stops. This should
capture the HRU and snap the lid into a locked position. Confirm that the
lid is attached to the bottom of the bracket and the HRU.
CAUTION: Do not force the lid closed. If the lid does not close
easily, check to see that the beacon is properly installed in the bracket
and the HydroFix™ is properly seated.
