Warnings and Cautions
R
• Follow the installation instruction steps to ensure the performance of the closure. It is necessary to take
precautions and keep the working space clean to protect the closure sealing materials and splices.
• Exposure to laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical
fiber. Do not assume the laser power is turned off or that the fiber is disconnected at the other end. Looking into
the ends of any optical fiber is entirely at your own risk. A protective cap or hood MUST be immediately placed
over any radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of radiation
exposure. This practice also prevents dirt particles from entering the connector and adapter.
• Fiber optic cables may be damaged if bent or curved to a radius that is less than the recommended minimum bend
radius. Always observe the recommended bend radius limit when installing fiber optic cables, subunits and patch
cords.

Tools
The following basic tools, auxiliary equipment, and materials are required for cleaning:
• 216B key tool (used to open optical port dust cap)
• Hardened connector/adapter cleaning kit

Cleaning the full size hardened connector and adapter
Use the following procedure for cleaning the hardened drop connector using the hardened connector/adapter cleaning
kit (accessory kit
FHD-ACC-CLNKIT1
).
5.1
Full size hardened connector cleaning
1. If the connector has been in use, clean the connector body, preferably using compressed air, to minimize
contaminants introduced to the ferrule.
2. Unscrew connector from its optical port or unscrew dust cap from the end of the connector.
3. Examine the end of the connector and determine which is the high side and which is the low side of the connector
end-face as shown in the figure above.
