8.1.1 Cleaning the Fans
If the fan guards are only dirtiedwith loose dust, they can be cleaned with a vacuum cleaner. If you
do not achieve satisfactory results with a vacuum cleaner, dismantle the fan for cleaning.
To do so, proceed as follows:
1. Disconnect the Sunny Mini Central from both the DC and AC connections, as described in
section 7.1 „Opening the Sunny Mini Central" (46).
2. Wait for the fans to stop rotating.

plastic cover to one side and remove it carefully
with the fan guards mounted behind it.
4. Clean the fan guard with a soft brush, a paint brush,
a cloth, or compressed air.

5. Press the front latches backwards and the rear
latches forwards.
6. Remove the fan by pulling it slowly and carefully
downwards.
7. Unlock and remove the plugs.
The fan cables are long enough that you can lift the
fans far enough out to disconnect the internal plugs
in the Sunny Mini Central.
8. Remove the fan and clean it with a soft brush, a
paint brush, or a cloth and water.
Do not use compressed air as this can damage the
fan.
9. After cleaning, assemble everything in reverse
order.
10. Check that the fans are functional as described in the next section.
