8. Appliance description
The appliance offers frost protection for the connection lines. The
integral frost protection circuit starts the circulation pump in the
heat pump circuit automatically at a condenser temperature of
8°C, and thereby ensures circulation in all water-carrying sec-
tions. If the temperature inside the buffer cylinder drops, the heat
pump starts automatically no later than when the temperature
falls below +5°C.

9. Preparation
!
D0000060163
The appliance is designed for siting in front of a wall. Observe the
minimum clearances. If the appliance is installed in an open space
or on a roof, protect the air intake side. Do this by erecting a wall
to shield it against the wind.
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.
- Noise propagation can also be reduced through dense pali-
sades or similar.
Ensure that the entire appliance frame is in full contact
with the substrate. Uneven substrates can increase sound
emissions.
Ensure that the air intake direction is the same as the dom-
inant wind direction. Air should not be drawn in against the
wind.
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.
Avoid installation on large, echoing floor areas, e.g.tiled
floors.
Avoid installation between reflective building walls. Reflect-
ing building walls can increase the noise level.
