First of all, you have to find an appropriate place. The requisites are two:
Take the "L" wall mount, and attach it to the wall manually. Mark the positions of the future holes on the wall.
Now, drill the four holes. Take into account the right diameter (see the number engraved on the wall plug). The ideal depth for the holes is about 0,5 cm + wall plug length.


Insert the four wall plugs in their holes, take the helping tool in each of them, and use the hammer to fix them.

Now take the "L" wall mount, and screw it on the wall using also the washers.
Let's mount the dish!
