Operating Properties
Operating temperature: 10°C to 35°C
Operating humidity: 8-80% (non-condensing)
Non-operating temperature: -40°C to 60°C
Non-operating humidity: 20%-95% (non-condensing)

1) The ambient temperature and relative humidity of the environment depend on the inlet supply water temperature and the coolant flow rate.
2) If the relative humidity surpasses 60%, maintain the inlet water temperature between 40°C and 45°C to prevent condensation and ensure optimal system performance.
