45° (in either direction). Do not lift unit by the holes in the panel assemblies! Flush the heating system prior to connecting the heat pump. The supplied strainer is to be fitted in the heat source inlet of the heat pump in order to protect the evaporator against contamina- tion. The brine must contain at least 25 % of a frost and corrosion protection agent on a monoethylene glycol or propylene glycol basis. The clockwise phase sequence must be observed when connecting the load line. Commissioning of the heat pump must be performed in accordance with the mounting and operating manual of the heat pump controller. CAUTION! CAUTION! CAUTION! CAUTION! CAUTION! CAUTION! CAUTION! CAUTION! CAUTION! CAUTION! Any work on the heat pump may only be performed by authorised and qualified customer service technicians. All power circuits must be dis- from the power source prior to opening the cabinet. 1.2 Legal Provisions and Directives This heat pump conforms to all relevant DIN/VDE regulations and EU directives. For details refer to the EC Declaration of Conformity in the appendix. The electrical connection of the heat pump must be performed according to and conforming with all relevant VDE, EN and IEC standards. Beyond that, the connection requirements of the local utility companies have to be observed. The heat pump is to be connected to the heat source and heat distribution systems in accordance with all applicable provisions. 1.3 Energy-Efficient Use of the Heat Pump By operating this heat pump you contribute to the protection of our environment. A prerequisite for an efficient operation is the proper design and sizing of the heating system and the heat source system. In particular, it is important to keep water flow temperatures as low as possible. All energy consumers connected should therefore be suitable for low flow temperatures. A 1 K higher heating water temperature corresponds to an increase in power consumption of approx. 2.5 %. Underfloor heating systems with flow temperatures between 30 °C and 40 °C are optimally suited for energy-efficient operation. 3 PURPOSE OF HEAT PUMP BASELINE UNIT PURPOSE OF THE HEAT PUMP 2.1 Application The brine-to-water heat pump is designed for use in existing or newly built heating systems. Brine is used as the heat carrier in the heat source system. Ground coils, ground collectors or similar systems can be used as the heat source. 2.2 Principle of Operation The heat generated by the sun, wind and rain is stored in the ground. This heat stored in the ground is collected at low temperature by the brine circulating in the ground collector, ground coil or similar device. A circulating pump then conveys the warmed brine to the evaporator of the heat pump. There, the heat is given off to the refrigerant in the refrigeration cycle. When so doing, the brine cools so that it can again take up heat energy in the brine circuit. The refrigerant, however, is drawn in by the electrically driven compressor, is compressed and "pumped" to a higher temperature level. The electrical power needed to run the compressor is not lost in this process, but most of the generated heat is transferred to the refrigerant as well. Subsequently, the refrigerant is passed through the condenser where it transfers its heat energy to the heating water. Based on the thermostat setting, the heating water is thus heated to up to 55 °C. 3 BASELINE UNIT The baseline unit consists of a heat pump, ready for connection, for indoor installation, complete with sheet metal cabinet, control panel and integrated controller. The refrigeration cycle contains the refrigerant R407C. Refrigerant R407C is CFC-free, non-ozone depleting and non-combustible. All components required for the operation of the heat pump are located on the control panel. The power feed for the load and control current must be field- installed by the customer. The supply lead of the brine pump (to be provided by the customer) must be connected to the control panel. When so doing, a motor protecting device is to be installed, if required. The collector loops including brine manifold must be provided by the customer. 1 23 4 1) Condenser 3) Evaporator 2) Control panel 4) Compressor 4 ACCESSORIES TRANSPORT ACCESSORIES TRANSPORT 45 4.1 Brine Manifold The brine manifold ties the individual collector loops of the heat source system into a single main line which is connected to the heat pump. Integrated ball valves allow individual brine circuits to be shut off for venting purposes. A lift truck is suited for transporting the unit on a level surface. If the heat pump needs to be transported on an uneven surface or carried up or down stairs, carrying straps may be used for this type of transport. These straps may be passed directly underneath the wooden pallet. wooden pallet. more than max. 45° (in either direction). For lifting the unit without pallet, the holes provided in the sides of the frame should be used. The side panel assemblies must be removed for this ...
