English LI 1422C - 1826C 2.2 Operating principle Intended use of the heat pump Heat Outside air is drawn in by the ventilator and fed via the evapora- 2.1 Area of application tor (heat exchanger). The evaporator cools the air, i.e. extracts heat from it. -
Page 7: Scope Of Supply
LI 1422C - 1826C English Scope of supply 3.1 Basic device 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”. -
Page 8: Transport
English LI 1422C - 1826C Transport CAUTION! Risk of injury when lifting and setting down the load. Risk of crushing! Do not stand under the load when lifting and setting down. CAUTION! Risk of injury if unsuitable lifting devices are used incorrectly. - Page 9 LI 1422C - 1826C English For easier transportation into existing homes/buildings, it is possible to separate the basic device into two parts. Once the covering panels have been removed, please proceed as follows: Drain refrigerant Remove condensate hose Loosen the switch box from the frame Remove the pipe insulation above the soldering points Separate 4x soldering points chip-free.
