The heating water temperature in the buffer tank must not be allowed to drop below 20 °C during this process. This ensures that the heat pump can be defrosted at any time. 6) Set the minimum volume flow quantity on the overflow valve and heat circulating pump when all heating circuits are fully open and a heating water temperature in the buffer tank of approx. 20 °C is maintained. 7) New buildings have an increased heat consumption on account of the energy required to dry them out. This increased heat consumption means that marginally dimensioned heating systems can not always achieve the desired room temperature. In such cases, we recommend keeping a second heat generator on standby during the first heating period. The limit temperature on the heat pump controller should also be turned up to 15 °C. 8 Maintenance / Cleaning 8.1 Maintenance To protect the paintwork, avoid leaning anything against the device or putting objects on the device. External heat pump parts can be wiped with a damp cloth and domestic cleaner. A ATTENTION!_ Never use cleaning agents containing sand, soda, acid or chloride as these can damage the surfaces. To prevent faults due to sediment in the heat exchanger of the heat pump, ensure that the heat exchanger in the heating system cannot be contaminated. In the event that operating malfunctions due to contamination still occur, the system should be cleaned as described below. The device may only be cleaned according to the following instructions from the manufacturer. 8.2 Cleaning the Heating System The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust), particularly if steel components are used. These products enter the heating system via the valves, the circulating pumps and/or plastic pipes. It is therefore essential - in particular with respect to the piping of underfloor heating systems - that only diffusion-proof materials are used. A ATTENTION!_ We recommend the installation of a suitable corrosion protection system to prevent the formation of deposits (e.g. rust) in the condenser of the heat pump. Residue from lubricants and sealants may also contaminate the heating water. In the case of severe contamination leading to a reduction in the performance of the liquifier in the heat pump, the system must be cleaned by a heating technician. According to today's state of knowledge, we recommend using a 5% phosphoric acid solution for cleaning purposes. However, if cleaning needs to be performed more frequently, a 5% formic acid solution should be used. In either case, the cleaning fluid should be at room temperature. We recommend flushing the heat exchanger in the direction opposite to the normal flow direction. To prevent acidic cleaning agents from entering the heating system circuit, we recommend connecting the flushing device directly to the flow and return flow of the liquifier of the heat pump. It is important that the system be thoroughly flushed using appropriate neutralising agents to prevent any damage from being caused by cleaning agent residue remaining in the system. Acids must be used with great care and all relevant regulations of the employers' liability insurance associations must be adhered to. If in doubt, contact the manufacturer of the chemicals! E-7 English English 8.3 8.3 Cleaning the Air System Evaporator, ventilator and condensate outflow should be cleaned of contamination (leaves, twigs, etc.) before each new heating period. A ATTENTION!_ Before opening the device, ensure that all circuits are isolated from the power supply. To prevent the evaporator and the condensate tray from being damaged, do not use hard or sharp objects for cleaning. A ATTENTION!_ The refrigerating circuit may not be damaged in any way. Inflammable refrigerant could leak out if the refrigerating circuit is damaged. Ignition sources and open flames must be avoided when carrying out any work on the device. Under extreme weather conditions (e.g. snow drifts), ice may form on the air intake and exhaust air outlet grids. If this happens, the ice must be removed in the vicinity of the air intake and exhaust air outlet grids to ensure that the minimum air flow rate is maintained. 9 Faults / TroubleShooting This heat pump is a quality product and is designed for troublefree and maintenance-free operation. In the event that a fault should occur, it will be indicated on the heat pump manager display. Simply consult the Faults and Trouble-shooting page in the operating instructions of the heat pump manager. If you cannot correct the fault yourself, please contact your after-sales service technician. A ATTENTION!_ Any work on the heat pump may only be performed by authorised and qualified after-sales service technicians. Anyone carrying out work on the refrigerating circuit must be certified to safely handle inflammable refrigerants or be supervised by a person having such certification. 10 Decommissioning/...
