7 Maintenance and care
Because the Windy Boy 5000 / 6000 can be used outdoors in places that are difficult
to access, the Windy Boy has been constructed for low maintenance. To guarantee
safe operation, it is usually adequate to check the device visually for damage appro-
ximately every two months. It should also be checked if the red LED is illuminated
and, if necessary, remove the fault by referring to chapter 3.3.4 "Description of the
operational status” (page 19).
In the interests of maximum yield, the operator should check, weekly if possible, un-
der various conditions of solar irradiation, if the displays of the Windy Boy 5000 /
6000 indicate plausible normal operation (cf. chapter 3.3.4 "Description of the ope-
rational status” (page 19)). Naturally, this information can be obtained by using one
of the communications options.
Cleaning of the Windy Boy is only necessary when the heat dissipation is limited by
dirty cooling fins or a dirty space between the Windy Boy and the wall. The dirt
should be carefully removed with an appropriate soft brush or paintbrush.
If the LEDs are so dirty that they can no longer be seen, then they can be cleaned
with a damp cloth. Solvents, abrasives or corrosive liquids must not be used!
