Page 6: Operating Principle
DIMENSIONS 7. OPERATING PRINCIPLE The heat pump appliance is used to acquire low-temperature energy from the selected source and its transfer to higher temperature level. The air to water heat pump extracts heat from the ambient air. The core of the heat pump serves as an efficient compressor through which the refrigerant is compressed and then expanded in a hermetically closed circuit. -

Page 16: Maintenance
11. MAINTENANCE Due to its design the heat pump is very easy to maintain. Basic maintenance is performed by the servicing organization once a year. During this regular maintenance, all important elements of the heat pump are checked. Special attention is paid to the correct volume of refrigerant in the circuit and a proper operation of the refrigerant circuit. -
