16. MAINTENANCE
If used in very dusty environments the air filter supplied separately can be installed behind
the front panel grid.
Therefore the user only needs to periodically check and clean the air filter on the front
panel (if any).
The frequency of air filter inspection depends how dusty the amplifier location is and how
much it is used. We recommend monthly cleaning of the filter.
Twice yearly cleaning of the fans with a soft brush is also recommended.
To clean the filter
a) Remove the front grid cover with the two small screws.
Place small screws in a secure place. DO NOT LOSE THEM.
b) Remove the filter and clean it with care.
c) Reassemble the filter and the grid after having carefully cleaned the mechanical
structure that includes them. Dry filter before re-installing.
Note: Check the filter if an unexpected rise of temperature of the linear is noticed.
Note: To allow the most efficient heat-dissipation of the power amplifier circuits, large
copper parts have been used.
