C.5.10 TPU Cooling
For proper unit cooling, any unused board slots should be closed with a blank
panel.
The TPU also has an air filter
which is accessible from the
right side of the front panel as
shown in Figure C-14. This
filter should be cleaned once a
month. To remove the filter,
pull it straight out from the
front panel using the two tabs.
Use compressed air to clean
the filter or wash it in clean,
fresh water. To replace the air
filter, slide it back into the slot.
