9 Maintenance and Care
The Sunny Island 3324/4248 has been constructed for low maintenance. Thus, the
necessary work is limited to only a few points:
9.1 Housing
Check that the Sunny Island 3324/4248 housing is mechanically sound. If damage
(e.g. cracks, holes, missing covers) endangers the operating safety, the Sunny Island
3324/4248 must be deactivated immediately.
Larger particles of dirt should be removed from the inverter with a soft brush, or
similar object. Dust can be removed with a damp cloth. Solvents, abrasives or
corrosive materials must not be used for cleaning!
9.2 Cleaning the Fans
The cleaning intervals depend on the ambient conditions. We recommend inspecting
the filters at least once a month.
If the fans are covered with loose dust, you can clean them with the aid of a vacuum
cleaner (recommended) or a soft brush. Clean the fans only when at a standstill. If it
is necessary to replace the fans, please contact your installer.
9.3 Display
It is best to clean the control elements with a soft, damp cloth. Solvents, abrasives or
corrosive materials must not be used for cleaning!
Take care not to accidentally press the membrane keys during
cleaning. Either clean the membrane keypad when the inverter is
deactivated, or make sure that the password protection is active.
