Mounting the Sunny Mini Central

4

When transporting and installing the
Sunny Mini Central, use the ergonomic
handles at the top and bottom at the
sides of the Sunny Mini Central (A), or
the housing opening, for example by
inserting a steel bar (B) (diameter max.
30 mm).

5

Hang the Sunny Mini Central using the
mounting holes on the rear face into
the wall bracket.
Take care to ensure that the Sunny
Mini Central locks audibly into place
in the wall bracket.

6

Fix the Sunny Mini Central to the wall
bracket using the two enclosed M6 x 8
mm bolts on both sides of the Sunny
Mini Central.
Fasten the bolts so that they are hand-
tight!

7

Make sure that the Sunny Mini Central is positioned securely on the bracket.
