Note
Output data to EN 14511 corresponds to a tempera-
ture spread of 3 K at a brine inlet temperature of 8 °C
and brine outlet of 5 °C.
Note
A reduced flow rate results in a lower heat pump out-
put. (This also applies in partial load operation)
Note
The specifications in the datasheets and the product
description describe purely physical characteristics.
Additional assurances or guarantees require a sepa-
rate contractual agreement.
Note
Operation as water/water heat pump with intermediate
circuit:
If the brine temperature of the intermediate circuit is
reduced to 6 °C instead of 8 °C, the output and effi-
ciency of the heat pump are reduced by approx. 5 %.
Note
The specified pressure drop refers only to the integral
heat exchangers in the heat pump and the connecting
flange.
Note
Failure to achieve the minimum frost protection may
cause damage and thus malfunction of the heat pump.
Note
Using too much antifreeze or selecting excessive frost
protection will reduce heating output.
