Remarks: 1. Nominal cooling capacity reference: ambient temperature: 35 ºC, evaporator inlet and outlet water temperature 12 ºC / 7 ºC.
2. Working range: the temperature of chilled water can be set and adjusted from 5 ºC to 25 ºC; the temperature difference between inlet and outlet of chilled water is 2.5 ºC to 7 ºC.
3. When the external environment temperature is lower than 3 ºC, ensure the indoor heating and water circulation or add antifreeze to prevent cracking; if it is not used for a long time, the accumulated water in the equipment should be drained or antifreeze should be added to prevent cracking.
