Page 8: General
General General Transporting and storage The heat pump should always be transported and stored in an upright position. Otherwise the suspension fi ttings inside the compressor can be damaged. If the heat pump must be tilted during entry to the installation site, this should be done for as short a time as possible. -
Page 9: Minimum And Maximum Working Temperatures
General Minimum and maximum working temperatures Maximum working temperatures The heat pump can work with a maximum return temperature of approxi- mately 59ºC. If the temperature rises above this value the heat pump will stop for reasons of technical safety. In the event of additional heat only, the maximum fl... -

Page 18: Flushing The Heating System
Connecting to the heating system Flushing the heating system It is important that all previously mentioned preparations have been carried out before the heat pump is connected to the heating system. Also ensure the heating system has been well fl ushed before the heat pump is installed. Flushing protects Note the heat pump from contamination. -
Page 19: Principle Method Of Operation
Connecting to the heating system Principle method of operation The principle method of operation is based on the vapour compression cycle with any additional heat being provided by the built in electric heater. The control unit controls the heat pump using the outdoor sensor T2 and the fl ow sensor T1 according to the set heat curve. -
