Step Instruction
1 Disconnect the Sunny Mini Central from both the DC and AC connections,
paying attention to the safety instructions in section 3 "Safety Instructions"
(Page 9).
2 Wait for the fans to stop rotating.
3 Push the two latches at the upper edge of the black plastic cover to one side
and remove it carefully with the fan guards mounted behind. Clean the fan
guards with a soft brush, a paint brush, a cloth or compressed air. If the fans
are very dirty, you can clean them following the procedure laid out from step
4 onwards.
4 The fans are attached to the housing via
three snap fits. Press the two front snap
fits back and the rear snap fit forwards.
5 Remove the fans by pulling them slowly and carefully downwards. The fan
cables are long enough that you can lift the fans far enough out to disconnect
the internal plug in the Sunny Mini Central. To do so, unlock the
corresponding plugs and remove them. You can now take out the fans and
clean them.
6 Clean the fans with a soft brush, a paint brush or a cloth and water. Under
no circumstances should you use compressed air to clean the fans as this can
damage them.
7 After cleaning, replace everything in reverse order. Subsequently, check that
the fans are functional as described in the next section.
