1. If necessary, the operating range can be extended to a brine inlet temperature of -10 °C. In this case, the minimum brine concentration must be adjusted to 30%. (Freezing tem-
perature -17 C°). At brine inlet temperatures of -10 °C to -5 °C, flow temperature rising from 55 °C to 62 °C.

3. These data indicate the size and capacity of the system according to EN 14511. For an analysis of the economic and energy efficiency of the system, the bivalence point and
controller should be taken into consideration. The specified values have the following meaning, e.g. B0/W35: Heat source temperature 0 °C and heating water flow temperature
55 °C. These specifications can only be achieved with clean heat exchangers. Information on maintenance, start-up and operation can be found in the respective sections of the
installation and operating instructions.

4. The specified sound levels apply if the supporting feet (available as an option) are not used. If the supporting feet are used, the level can increase by up to 3db (A).
5. The specified sound pressure level corresponds to the operating noise of the heat pump in heating operation with a flow temperature of 35°C. The specified sound pressure level
represents the free sound area level. The measured value can deviate by up to 16 dB(A), depending on the installation location.
