[. . . ] T  he heat pump must not be placed in a closed space, containing corrosive and explosive materials. T  he connection of the heat pump to the power supply must be performed in accordance with the standards for electrical installations. An appliance for the disconnection from the electrical network must be installed between the heat pump and the electrical network in accordance with the national installation regulations. I n avoidance of aggregate damage the heat pump must not operate without water in the tank. [. . . ] Connection options to different heating sources are shown below. EN Figure 8: Connecting to other heating sources W  ith a temperature decline of an additional heating source and with an enabled water circulation through the heat exchanger proper temperature control of the additional source must be ensured. I f the additional energy source is solar power, the operation of the aggregate of the heat pump must be shut off. The combination of two heating sources can lead to overheating of the hot water and thus to excessive pressures. t  he circulation pipeline causes additional temperature decline in the hot water storage tank. CONNECTION TO THE POWER SUPPLY NETWORK In order to connect the hot water storage tank with the heat pump to the power supply network first install an electrical socket suitable for the current load of 16 A. Connecting the heat pump to the power supply network must take place in accordance with the standards for electric appliances. To comply with the national installation regulations, an all poles disconnect switch must be installed between the heat pump and the power supply network.

When the screen is lit up, the operation fields are active. Defrosting takes place until the conditions for normal operation of the heat pump are achieved. After successful defrosting, the heat pump returns to normal operation (symbols 16 and 20 are displayed). If defrosting is unsuccessful, the controlling unit displays an error message. 4 starts flashing, accompanied by warning beeps. 12 and the pump switches automatically to heating with electric heaters. The error code can be deleted at any time by pressing field no. Setting the clock and day of the week • Hold field no. 7 shows a flashing number of the day of the week. € By pressing + or – you can set the number of the day of the week (1 – Monday, …, 7 – Sunday). 12 again (flashing hour setting is displayed). € By pressing + or – set the hour (by holding + or – you can speed up the setting). [. . . ] The water is drained via a drain valve on the inlet water pipe. The exterior of the heat pump should be cleaned with a mild detergent solution. do not use solvents or abrasive cleaning agents. If the heat pump was exposed to dust, evaporator lamellas might become blocked, which can have a detrimental effect on the functioning of the heat pump. [. . . ]
