Beware of the heat interface unit
falling
CAUTION!
Risk of injury due to the heat interface unit falling!
If the load-bearing capacity of the installation loca-
tion or the means of bolting it in place are not
designed for the weight of the heat interface unit,
there is a risk of injuries to persons and damage to
property due to the heat interface unit falling down.
– Ensure that the load-bearing capacity of the wall
is sufficient. If necessary, consult a structural
engineer.
– Ensure that the means of bolting the unit in
place are dimensioned for the weight of the heat
interface unit.
– The weight specifications can be found in
chapter
Ä Chapter 16 ‘Technical data’
on page 65.
Requirements of the installation location:
n The room must be dry and frost-free.
n The installation location must satisfy protection class IP30.
n The installation location must be designed for the dimensions of
the heat interface unit. The dimensions can be found in chapter
Ä Chapter 16 ‘Technical data’ on page 65.
n The heat interface unit must be connected to a mains voltage of
230 VAC ± 10% with a grid frequency of 50–60 Hz.
Requirements of the water quality:
n Take corrosion protection and limescale into account in accord-
ance with country-specific regulations and standards.
n Carry out a drinking water analysis in accordance with country-
specific regulations and standards.
n If necessary, install suitable water filters in the drinking water
supply line of the building inlet.
If the pipes in the section of the building are
awaiting testing but the heat interface unit cannot
yet be installed, the fix rail can be mounted. The
pipes in the section of the building can be con-
nected to the connecting rail and the supply lines
can then already be tested for leaks this way.
