Air Filter

Over a long period of time, dust may block the air filter at the air intake vent of the S7500E series. As a
result, the heat dissipation of the system may be affected. You are recommended to clean the air filter
every three months. Air filters are optional accessories.
Since the air flows up from the bottom, air filters for the S7506E-V, different from those for the other
models, are installed on the front and rear sides near the bottom of the chassis.
