You can restrict the maximum inlet temperature by installing a
central thermostatic valve.
13.13 Horizontal installation of the appliance
Note
For the horizontal installation alternative, please note
the following points:
- Installation is only permissible with direct wall
mounting. The universal mounting frame cannot be
used.
- The installation versions "Installation with offset
tiles" and "Rotated appliance cover" are not permis-
sible.
- This type of connection changes the IP rating of the
appliance. Cross out "IP 25" on the type plate and
mark the box "IP 24". Use a ballpoint pen to do this.
Horizontal installation
The appliance can also be mounted horizontally on the wall
(turned 90° to the left, with the water connections on the right).
The installation, water and electrical connections are described
in chapters "Standard installation" and "Alternative installation
methods".
