Removing and Replacing a Cooling Fan
Always use an Electrosonic Replacement Fan, Part No. ES3301-F or ES3302-F.
Remove the upper access panel by unscrewing the two thumbscrews.
Unplug the supply lead to the faulty fan.
Remove the single retaining screw from above the fan.
Withdraw the fan by tilting the top forward and lifting away.
NOTE: When replacing the fan ensure that the two lugs (on the base of the fan housing) correctly
locate inside the aperture in the card frame.
Cleaning the Ventilation Grilles & Filters
It is recommended that the front ventilation grilles and air filters are checked periodically for a build-up
of dust. Excess dust deposits will reduce the efficiency of the cooling fans and may cause the unit to
overheat.
To clean the grilles and filters, use a vacuum cleaner (and if necessary a soft brush) to remove any
dust deposits.
