Note
A reduced flow rate results in lower heat pump output
and efficiency at a constant return temperature (this
also applies in partial load operation).
Note
The technical information in the datasheets and prod-
uct description describe purely physical characteristics.
Additional assurances or guarantees require a sepa-
rate contractual agreement.
Note
The specified pressure drop refers 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.
