rust) in the condenser of the heat pump. A ATTENTION!_ Before opening the device, ensure that all circuits are isolated from the power supply. A ATTENTION!_ The refrigerating circuit may not be damaged in any way. 1.2 Legal Regulations and Directives The construction and design of the heat pump complies with all relevant EU directives, DIN/VDE regulations (see CE declaration of conformity). The relevant VDE, EN and IEC standards must be adhered to when connecting the heat pump to the power supply or carrying out maintenance work. Any further connection requirements stipulated by local utility companies must also be observed. When connecting the heating system, all applicable regulations must also be adhered to. A ATTENTION!_ Any work on the heat pump may only be performed by authorised and qualified after-sales service technicians. Persons, especially children, who are not capable of operating the device safely due to their physical, sensory or mental abilities or their inexperience or lack of knowledge, must not operate this device without supervision or instruction by the person in charge. Children must be supervised to ensure that they do not play with the device. 1.3 Energy-Efficient Use of the Heat Pump With the purchase of this heat pump you are helping to protect the environment. A prerequisite for energy-efficient operation is the correct design of the heat source system and heating system (radiators and circulation pump). To maintain heat pump efficiency, it is particularly important to keep the temperature difference between the heating water and heat source to a minimum. For this reason, it is advisable to design the heat source and heating system very carefully. A temperature difference of approx. one Kelvin increases the power consumption by around 2.5%. When designing the heating system, it should be borne in mind that special consumers such as e.g. DHW preparation should also be taken into consideration and dimensioned for low temperatures. Underfloor heating systems (panel heating) are optimally suited for heat pump use on account of the low flow temperatures (30 °C to 40 °C). It is important to ensure that the heat exchangers are not contaminated during operation because this increases the temperature difference, in turn reducing the COP. Correct adjustment of the heat pump controller is also important for energy-efficient use of the heat pump. Further information can be found in the operating instructions of the heat pump controller. E-2 3.1 2 Purpose of the Heat Pump 2.1 Application The air-to-water heat pump is designed for use in existing or newly built heating systems. It is designed exclusively for heating domestic hot water and heating water! The heat pump is suitable for mono energy and bivalent operation down to an external temperature of -20 °C. Proper defrosting of the evaporator is guaranteed by maintaining a heating water return flow temperature of more than 13 °C during continuous operation. The heat pump is not designed for the increased heat consumption required when a building is being dried out. The additional heat consumption should be met using special devices provided by the customer. If a building is to be dried out in autumn or winter, we recommend installing an additional heating element (available as an accessory). A ATTENTION!_ The device is not suitable for operation with a frequency converter. 2.2 Operating Principle Surrounding air is drawn in by the ventilator and fed via the evaporator (heat exchanger). The evaporator cools the air, i.e. it extracts heat from it. This extracted heat is then transferred to the working medium (refrigerant) in the evaporator. The heat is “pumped” to a higher temperature level by increasing its pressure with the aid of electrically driven compressors. It is then transferred to the heating water via the liquifier (heat exchanger). Electrical energy is used to raise the temperature of the heat in the environment to a higher level. Because the energy extracted from the air is transferred to the heating water, this type of device is called an air-to-water heat pump. The air-to-water heat pump consists of the main components evaporator, ventilator and expansion valve, as well as the low-noise compressors, the liquifier and the electrical control system. At low ambient temperatures, humidity accumulates on the evaporator in the form of frost reducing the transfer of heat. The evaporator is defrosted automatically by the heat pump as required. Steam may be emitted from the air outlet depending on the atmospheric conditions. 3 Scope of Delivery 3.1 Basic Device The heat pump is of compact design and is supplied complete with the components listed below.
