6.8 Replacing and Cleaning the Air Filter
An air filter is installed at the air intake vent of the power module of the S7500 series.
Dust in the air may block the vent on the air filter over a long period of time, which
affects the heat dissipation of the power module. You are recommended to clean the air
filter every three months.

For detailed description about removal and installation of the air filter, see the related
