Servicing Frame Power Supplies
Frame Air Filter Cleaning
The air filter at the bottom of the Signal Processor Frame reduces the accumulation
of dust in the electronic circuitry. The filter should be checked and cleaned
regularly. See
A fan at the top of the frame draws air up through the circuit cards from inlets at
the bottom. Cooling air entering the frame passes through the slide-in air filter
then out the vents at the top of the frame.
