    1. The "cooling capacity" is tested based on: Inlet and outlet water temperature of freezing is 12℃/7℃, and the inlet and outlet water temperature of cooling is 30℃/35℃.

    2. Working temperature range: Chilled water temperature range is 5℃-35℃, inlet and outlet water temperature difference is 3℃-8℃, condensation temperature not higher than 35℃.

    3. Conversion of units: 1 ton cooling capacity=3024kcal/hr, 1kcal/hr=3.969BTU/hr, 1HP=0.735kW=2580kcal/hr

    3 tips for startup of newly purchased water chiller

    The following items must be checked before the first operation:

    1. Check whether the power supply voltage and phase number meet the model and specification, please refer to the nameplate. (Note: the power supply of ATO air-cooled water chiller above 3HP is 3-phase 4-wire, voltage is 220V ~ 480V / 50Hz or 60Hz, power phase lines are R, S and T respectively, the neutral line is N, and the grounding wire is two-color wire, represented by E. When the light is not on or the red light is on and the fault code and alarm number are displayed during the first start-up, any two phases of the phase line can be exchanged, and the switch can be closed after the connection.)

    2. Check whether the chilled water pipe and cooling circulating water pipe are connected to the pipeline and keep the valve open.

    3. Fill the freezing water tank with water or other freezing medium before starting the water pump. (please use refrigerant as required).
