Maintenance and Care

17 Maintenance and Care
The Sunny Island 5048 has been constructed for low maintenance. Thus, the necessary
work is limited to only a few points.

17.1 Housing

Check that the Sunny Island 5048 housing is mechanically sound. If damage (e.g.
cracks, holes, missing covers) endangers the operating safety, the Sunny Island 5048
must be deactivated immediately.
Larger particles of dirt should be removed from the device 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!

17.2 Cleaning the Fans

The cleaning intervals depend on the ambient conditions. 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.

17.3 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.
Only clean the membrane keypad when the device is deactivated.

17.4 Functioning

Check regularly whether error messages are present. If an error message is displayed,
for which you cannot identify any apparent cause, the stand-alone grid must be
inspected by an installer. To ensure optimal operation, the operator should regularly
check the entries in the Sunny Island 5048 error list at short intervals (monthly, or even
weekly), especially during the first months after commissioning. This can help to
discover hidden faults in the installation or errors in the configuration.
