- Page 7 Refrigerant R-410A is a fluorinated greenhouse gas and, consequently, subject to the EU F-gas Regulation. Please recover the refrigerant as required by law, and transfer the refrigerant for recycling or disposal as required by applicable laws, rules and regulations. The refrigerant is heavier than air. The refrigerant may accumulate in enclosed spaces, especially at or below the floor level (for example, in basements).

Page 46: Operation
5 Operation 5.1 Heat pump operation The system’s connection diagrams are provided as a separate document. The heat pump collects heat from the fluid in the brine circuit and releases the heat collected through a condenser and into heating water. In addition to the heat pump itself, CUBE heat pump units include an in-line heater for supplementary and backup heating. - Page 47 determines when heating starts (instead of the flow water temperature). Whenever the building’s domestic hot water needs heating, space heating will be suspended until domestic hot water has been heated to a sufficient temperature. Domestic hot water tank heating will start when the DHW tank temperature (minus the switching difference) falls below the domestic hot water target temperature.
