7. Safety
Only a qualified contractor should carry out installation, commis-
sioning, maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
7.2 Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
8. Appliance description
For outdoor installation the appliance offers additional frost pro-
tection of the heating water pipes. The integral frost protection
circuit starts the circulation pump in the heat pump circuit auto-
matically at +8 °C condenser temperature, and thereby ensures
circulation in all water-filled sections. The heat pump is started
automatically no later than when the temperature inside the buffer
cylinder drops below +5 °C.

9. Preparation
9.1 Sound emissions
The appliance is louder on the air intake and air discharge sides
than on the two enclosed sides. Take the following information
into account when selecting the installation location.
Note
For details regarding the sound power level, see chapter
"Specification / Data table".
- Lawn areas and shrubs help reduce the spread of noise.
- Sound propagation can also be reduced by installing closely
spaced palisade fencing around the appliance.
f
Ensure that the entire appliance frame is in full contact with
the substrate. Uneven substrates can increase sound emis-
sions.
f
Ensure that the air intake direction is the same as the main
wind direction. Air should not be drawn in against the wind.
f
Ensure that the air intake and air discharge are never direct-
ed towards noise-sensitive rooms of the house, e.g. bed-
rooms, or neighbouring houses.
f
Avoid installation on large, echoing floor areas, e.g. tiled
floors.
f
Avoid installation between reflective building walls. Reflect-
ing building walls can increase the noise level.

f
Never install the appliance in a recess. Two sides of the ap-
pliance must remain exposed.
f
In order to prevent air "short circuits", maintain the minimum
clearances in the case of surrounding structures and in par-
ticular in the case of cascades. Maintain the flow rate on the
heat source side (see chapter "Specification / data table").
