* 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
(% # 45 K). A pressure drop of 0.1 MPa (1 bar) is recommended for pipe network dimensioning, in line with DIN 1988 Part 3, Table 4.

2.6 Installation location

The DHF ... C compact control is to
be installed vertically in accordance
with A (over-sink or under-sink) in a
closed, frost-free room, as near as possible
to the tap point (a dismantled unit is to be
stored in frost-free conditions, since resi-
dual water always remains in the unit).

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
isolating valve (
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).

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).
