Installation
When planning building-in niches,
please note that the niche into which
the appliance with the side panel
heater is installed must be 4 mm
wider (see "Installation – Installation
dimensions").
If the partition wall (a) is thicker than
160 mm, you do not need the side-by-
side installation kit, nor the side panel
heater.
. . . without partition wall
If the wine conditioning units/
refrigeration appliances are to be
installed next to each other without a
partition wall between them, they will
need to be joined together with the
side-by-side installation kit. In addition,
you must install the side panel heater to
prevent condensation from forming and
any resulting damage.
