place.
Align the mounted appliance by loosening the fixing toggle,
aligning the power supply and back panel, and then re-tight-
ening the fixing toggle. If the back panel of the appliance is
not flush, the appliance can be secured at the bottom with an
additional screw.
Wall mounting bracket when replacing an appliance
When replacing an appliance, you can use an existing wall mount-
ing bracket of a StiebelEltron appliance (except for a DHF instan-
taneous water heater).
Press the appliance over the threaded stud of the existing
wall mounting bracket. When doing so, push through the soft
seal in the back panel of the appliance. If necessary, use a
screwdriver.

ed stud to the position marked with DHF (the stud has a
self-tapping thread).

wall. Use the existing drill holes.
