1. The inlet cooling water temperature of fan coil unit should not be lower than 5°C, otherwise it may cause unit condensation. The temperature of the incoming hot water should not exceed 80°C (usually 60°C), otherwise it may cause corrosion of the copper tubes of the unit heat exchanger.
2. It is recommended that the operating temperature of the fan coil unit during cooling: 16 to 36°C, during heating: 10 to 30°C, and air relative humidity ≤ 90%.
3. The fan coil unit is only used as a comfort air conditioner and must not be used for special occasions.
4. Do not install fan coils in areas with corrosive gases.
