Sound Level - Wolf BWL-1 S Installation And Operating Instructions Manual

Sound level

Noise levels must be taken into consideration when siting the system.
In accordance with TA-Lärm [or local regulations], the following emission limits must be observed:
Area
Spa complexes, hospitals and care homes, where indicated as such by means of
signs on the premises or road.
Emission location surrounded exclusively by residential buildings (purely residential
areas)
Emission location surrounded primarily by residential buildings (generally residential
areas)
Emission location neither primarily surrounded by commercial facilities nor by
residential buildings (core areas, mixed areas)
Emission location surrounded primarily by commercial facilities (commercial areas)
Emission location surrounded exclusively by commercial facilities and perhaps the
occasional residential building for the owners and managers of the facilities and for
supervisors and on-call staff (industrial areas)
Measuring location outside the residence affected but close by (0.5 m in front of the open window that is most affected)
When siting the system, the following must be observed:
Avoid siting the heat pump directly by or below windows of noise-sensitive rooms, e.g. bedrooms.
Installation in recesses or between 2 walls is not recommended, as this will increase the noise level due to sound reflection.
The sound power level of heat pumps is calculated in accordance with DIN EN 12102. It enables comparisons to be made
independently of surroundings, direction and distance.
Installation up to 3 m from a wall (Q=4):
