8. ENCLOSURE INSTALLATION

8.1. Siting

The enclosure should be mounted upright against a vertical bulkhead. Alernately, it may be
mounted horizontally on a flat surface, such as a cabin roof. No other orientations are
recommended
If you have a float-free EPIRB it is critical that you choose a position where the released
EPIRB will not get trapped by overhangs, rigging, antennas etc., should the vessel ever
sink. An expanse of flat surface is required to allow the enclosure lid to eject. Use the list
below to choose a suitable mounting position:
• Mount on the outside of the vessel´s stru
• Mount close to the vessel´s navigation position.
• Consider ease of access in an emergency.
AVOID
• Po
sitions with insufficient space for lid ejection and maintenance.
• Positions within 1 m (3´) of any compass equipment.
• Mounting within 2 m (6´) of any Radar antenna.
• Direct impact from waves.
• Siting where damage is like
• Exhaust fumes, chemical and oi

8.2. Mounting procedure

mounting dimensions, or use the backplate of the enclosure as a marking guide. To do t
pull out the R-shaped clip and remove the enclosure lid. Note how the EPIRB fits then
