Page 6: Intended Use Of The Heat Pump
English LA 1422C 2.2 Operating principle Intended use of the heat pump Heating Outside air is drawn in by the fan and fed via the evaporator 2.1 Area of application (heat exchanger). The evaporator cools the air, i.e. extracts heat from it. -
Page 7: Scope Of Supply
LA 1422C English Scope of supply 3.1 Basic unit The heat pump contains the components listed below. The refrigeration circuit is "hermetically sealed" and contains the fluorinated refrigerant R410A incorporated in the Kyoto protocol. Information on the GWP value and CO equivalent of the refrigerant is available under “Device Information”. -
