Air Ducting Installation
The TWTA is cooled with an internal fan. Heated exhaust air
should not be recirculated into the TWTA. The air intake and
exhaust ports are located on the rear panel of the amplifier. A
clearance of 6-8 inches is recommended to allow the heated
exhaust air to clear the TWTA.
If the unit is installed in a closed cabinet or in a configuration
that would tend to divert or block the exhaust air, provisions
should be made to isolate the exhaust air from the intake air
supply.
The Exhaust Port Guard can be removed and replaced with an
air duct to carry the exhaust away from the TWTA. The air duct
is available from XICOM Technology. See appendix titled
Mechanical Drawings
.
