ASSEMBLING THE MOUNTING HOUSING
The product is available as a surface-mounted and flush-mounted version. In the flush-mounted version, the
front panel is slightly larger to better cover the hole in the wall, and the mounting housing (backbox) is made
entirely of metal instead of plastic.

(gas, water, etc.) are to be found in the wall.
If the wall of the house is made of wood, dowels are not normally required. There are special dowels for
assembling the device on an insulating wall, e.g. Fischer insulating dowels.
4.1 DISASSEMBLING THE FRONT PANEL
Remove the front panel with the attached Main Electrical Unit carefully from the mounting housing (backbox)
using the orange (Torx+Pin) screw driver provided.
We have designed the front panel and the safety screw in a way that it cannot be screwed through the
front panel so that is does not fall off / get lost during installation..
Flush-mounted model
Turn the safety screw counter-clockwise until it is loose. Pull the front panel with attached Main
Electrical Unit out of the mounting housing (backbox).
