The hydraulic plumbing diagram must be adhered to. A ATTENTION!_ The supplied dirt trap must be inserted in the heat source inlet of the heat pump to protect the evaporator against the ingress of impurities. In addition, a micro bubble air separator must be installed in the heat source system. The brine liquid must be produced prior to charging the system. The liquid must have an antifreeze concentration of at least 25 % to ensure frost protection down to -14 °C. Only monoethylene glycol or propylene glycol-based antifreeze may be used. The heat source system must be de-aerated and checked for leaks. A ATTENTION!_ The brine solution must contain at least a 25% concentration of a monoethylene glycol or propylene glycol-based antifreeze, which must be mixed before filling. 7.4 Electrical Connection The following electrical connections must be established on the heat pump: ■ Connection of the control line to the control panel of the heat pump via terminal X1: L/N/PE. ■ Connection of the mains cable to the control panel of the heat pump via terminal X6: L/N/PE. ■ Connection of the brine circulating pump (to be provided by the customer) to the control panel of the heat pump via terminal X1: PE and pump contactor K5: 14/24. As an option, the brine pump can also be directly connected (see terminal connection plan). All electrical components required for the operation of the heat pump are located on the control panel. For detailed instructions concerning the connection and functioning of the heat pump controller (e.g. external wall sensor included in the scope of supply) refer to the operating manual supplied with the controller. A disconnecting device with a contact gap of at least 3 mm (e.g. utility blocking contactor or power contactor) as well as a 1-pole circuit breaker have to be provided by the customer. The required conductor cross-section is to be selected according to the power consumption of the heat pump, the technical connection requirements of the respective utility company as well as all applicable regulations. Details on the power consumption of the heat pump are listed on both the product information sheet and the type plate. The connection terminals are designed for a max. conductor cross-section of 10mm2. E-5 English English 8 8 Commissioning 8.1 General Information To ensure that start-up is performed correctly, it should only be carried out by an after-sales service technician authorised by the manufacturer. This may be a condition for extending the guarantee (see Warranty).Start-up should be carried out in heating operation. 8.2 Preparation The following items need to be checked prior to start-up: ■ The heat pump must be fully connected, as described in Chapter 7. ■ The heat source system and the heating circuit must have been filled and checked. ■ The dirt trap must be inserted in the brine inlet of the heat pump. ■ All valves that could impair proper flow in the brine and heating circuits must be open. ■ The heat pump controller must be adapted to the heating system in accordance with the controller's operating instructions. 8.3 Start-up Procedure The heat pump is started up via the heat pump controller. A ATTENTION!_ The heat pump must be started up in accordance with the installation and operating instructions of the heat pump controller. If an overflow valve is fitted to assure the minimum heating water flow rate, the valve must be set in accordance with the requirements of the respective heating system. Incorrect adjustment can lead to faulty operation and increased energy consumption. We recommend carrying out the following procedure to correctly adjust the overflow valve: Close all of the heating circuits that may also be closed during operation (depending on the type of heat pump usage) so that the most unfavourable operating state - with respect to the water flow rate - is achieved. This normally means the heating circuits of the rooms on the south and west sides of the building. At least one heating circuit must remain open (e.g. bathroom). The overflow valve should be opened far enough to produce the maximum temperature spread between the heating flow and return flow listed in the table below for the current heat source temperature. The temperature spread should be measured as close as possible to the heat pump. The heating element of mono energy systems should be disconnected. Heat source temperature Max. temperature spread between heating flow and return flow From To -5° C 0° C 10 K 1° C 5° C 11 K 6° C 9° C 12 K 10° C 14° C 13 K 15° C 20° C 14 K 21° C 25° C 15 K Any faults occurring during operation are displayed on the heat pump controller and can be corrected as described in the operating manual of the heat pump controller. E-6 11 9 Maintenance and Cleaning 9.1 Maintenance The heat pump is maintenance-free. To prevent faults due to sediment in the heat exchangers, care must be taken to ensure that no impuritie...
