9.2 Cleaning the Handle Covers
There are handle covers on either side of the Sunny Boy. The Sunny Boy sucks air in from underneath
via the fan and blows it out again on the upper sides. For optimum heat dissipation within the device,
you have to clean both handle covers. Proceed as follows when cleaning the handle covers:
• The handle covers of the Sunny Boy are on the
sides of the enclosure. Place your fingers in the
space between the top of the housing and the
handle covers and gently pull the handle covers out
of their bracket.
• Insert the handle covers back into the Sunny Boy. The handle covers can only be inserted on
the right or left side of the Sunny Boy respectively. "links/left" or "rechts/right" is printed on the
inside of the handle covers to help you identify the sides.
The handle covers must not be removed permanently, because otherwise the device is not
protected against the entrance of insects! Should the handle covers break, new handle
covers can be ordered from SMA America.
