Sealite Breather Unit
How it Works
Inside the breather unit, is an air channel which forms in the shape of an S-Bend which runs from the
M16 threaded hole to a small hole located on the other side.
Thischannel,llswithwaterandspillsoutthroughthesmallhole,allowingthewatertoeffectively
drain from the buoy and at the same time, preventing water from entering into the buoy through the
small hole.
Installation Instructions for Breather Units (For Products which Contain Sealite’s Power Packs)
1. Unscrew the white plug located at the side/base of the buoy
2. Apply a small amount of marine grade silicon adhesive to the thread of the breather valve
3. Carefully screw in the breather unit ensuring that the arrow’s direction is pointing down.

Marine Buoy Maintenance
Sealite Marine Buoys are designed to require very little maintenance. We recommend the buoy be
inspected annually. Inspection may need to increase depending on the local conditions and the
position of the buoy.
IALA Recommendation AISM E-107 suggests moorings are inspected annually.
Marine Buoy – Annual Maintenance
• Visually inspect buoy for damage
• Inspect the top mark for any damage. Repair any broken or damaged section.
• Clean buoy of animal debris
Mooring – Annual Maintenance
• Check and clear the tail and ride chains from shells and algae.
• Check for wear on any shackle axis and check the tapered pins. Any worn shackles must be
replaced.
• Check the free movement of each swivel around its head. If any swivel head sticks it must be
replaced.
• Check every link of the thrash length of the chain. Check the diameter of the nips and sides and
also inspect the welds on every link.
• If depth allows, a worn riding chain may be reversed.
• Change a chain when any link shows excessive wear.
• Chain must be replaced if any link wears to less than 3/5 of the original diameter.
Mooring – Biannual Maintenance
• Inspect the ground chain and sinker.
Lanterns – Maintenance
• PleaserefertotheInstallationManualforthespecicMarineLanternttedtotheBuoy.
