8.3 Cleaning the fan gills
There are fan gills on the sides of the Sunny Boy 3800. If the filters of the fan gills are
so dirty that they block the air outflow, you can clean them as follows.
1. Remove the six screws which secure each fan gill
to the enclosure.
2. Remove the fan gills from the enclosure. Filters are
attached inside the fan gills. Clean them with a soft
brush, a paint-brush or compressed air.
3. Insert the fan gills back into the Sunny Boy 3800.
