* Pressure drop values also apply to the minimum flow pressure in accordance with
DIN 44851 / Flow rate for heating from 10 °C to 55 °C (∆ ϑ 45 K). A pressure drop of
0.1 MPa is recommended for pipe network dimensioning, in line with DIN 1988 Part 3,

2.6 Installation location

The DHF ... C compact control is to
be installed vertically in accordance
A
with (over-sink or under-sink) in a
closed, frost-free room, as near as possible
8.8
to the tap point (a dismantled unit is to be
stored in frost-free conditions, since resi-
dual water always remains in the unit).
2.7 Preparing for unit instal-
lation
B Turn locking cap (3) to the left and with-
draw.
Unscrew cover securing screw and re-
move device cover.
– Detach mounting bracket (19) from the
unit.
– Thoroughly flush through the cold water
supply pipe.
– In the case of a replacement installation,
the available cold water 3-way three-way

used.
– With the help of the template (separate
this from the operating and installation
instructions), determine the position of
the cable entry (concealed connection)
and the mounting bracket (19).
G Cut the electrical connection cable to
length and strip.
C
Secure the mounting bracket.
When replacing DHF/DHA old models
(height 370 mm), the available drilled
securing holes (20) can be used.
– Secure the unit to mounting bracket with
the screwed sleeve (14). Using the nut
on the threaded bolt (21), unevennesses
in the wall, caused for example by mis-
aligned tiles, can be compensated for
(maximum 12 mm).
