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). ATTENTION! The device is not suitable for operation with a frequency converter. 2.2 Operating Principle Outside 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 an electrically driven compressor. It is then transferred to the heating water using 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 compressor, liquifier and 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 compact heat pump is supplied complete with all the components listed below. R404A is used as the refrigerant. ............ 1) Evaporator 2) Check valve 3) Ventilator 4) Switch Box 5) Controllers 6) Filter dryer 7) Liquifier 8) Expansion valve 9) Compressor English E-3 3.2 English 3.2 Switch Box The switch box is located in the heat pump. It can be swung out after removing the lower front cover and loosening the fastening screw located in the upper right-hand corner. The switch box contains the supply connection terminals as well the power contactors and the soft starter unit. The power supply cable and control line are installed ready for use. 3.3 Heat pump controller ATTENTION! Use the heat pump controller included in the scope of supply to operate the air-to-water heat pump. The heat pump controller is a convenient electronic regulation and control device. It controls and monitors the entire heating system on the basis of the external temperature, including hot water preparation and safety systems. The customer must install the external temperature sensor, which is included in the scope of supply of the heat pump controller together with the necessary fixing accessories. The enclosed operating instructions describe the function and use of the heat pump controller. 4 Transport ATTENTION! When transporting the heat pump, care must be taken to ensure that it is not tilted more than 45° (in any direction). Use a wooden pallet for transporting the heat pump to the final installation location. The basic device can be transported with a lift truck, hand truck or by means of 3/4" pipes fed through the holes in the base plate or frame. ATTENTION! The heat pump and transport pallet are only joined by the packing film. Before using the transport holes in the frame, it is necessary to remove the lower side panel assemblies. This is done by loosening each of the two screws at the base and then withdrawing the panels by unhooking them from above. Rehang the panels by gently pushing them in an upwards direction. Be careful not to damage any components when inserting the pipes through the frame. .................................... ..

The entire base of the frame should lie directly on the floor to ensure a good soundproof seal. If this is not the case, additional sound insulation measures may be necessary. If the device is installed on top of a built-under buffer tank, a surface that fully supports the base is required. The heat pump must be installed so that maintenance work can be carried out without being hindered. This can be ensured by maintaining a clearance of 1 m in front and to the left and right of the heat pump. Never install the device in rooms subject to high humidity. Condensation can form on the heat pump and air circuit if the humidity exceeds 50 % and the external temperature is below O °C. If the heat pump is installed on an upper storey, the load-bearing capacity of the ceiling should be checked. On account of the acoustics, measures for isolating possible vibrations should also be very carefully planned in advance as well. Installation on a wooden floor is not recommended. 5.2 Condensed Water Pipe Condensed water that forms during operation must be drained off frost free. The heat pump must be mounted on a level plane to guarantee pr...
