Maintenance
5.1
INTRODUCTION
This section contains information to aid in the
maintenance of the B100 Terminal. Preventive
and corrective maintenance procedures are
specified as well as troubleshooting aids and
techniques.
5.2
PREVENTIVE MAINTENANCE
No scheduled periodic maintenance is required.
However, several precautions can be taken
periodically to ensure proper operation. Care
should be exercised to see that there is proper
air circulation for the fan. The terminal should
not be placed on a shag carpet or other soft sur
face that could impede the air entrance to the
fan. Special care must be taken to ensure that
no paper or other loose articles are placed under
the terminal. The degree of dust density in the
air should be considered in selecting the location
of the terminal.
The interior of the unit may be wiped free of
dust. Accumulation of dirt causes overheating and
component breakdown. Dirt acts as an insulating
blanket and prevents efficient heat dissipation. A
small brush is very useful for dislodging dirt; a cot
ton-tipped applicator is good for narrow or hard
to get places.
The following is a list of the troubleshooting aids
that are provided in this manual to assist in the
troubleshooting of functional failures.
