Steps
1. Ensure that the ground of the installation site is flat, well ventilated, free of flammable and explosive corrosive gases, and leave appropriate maintenance space.
2. Connect the power supply and check whether the voltage and frequency meet the requirements (AC380V three-phase four-wire system, voltage fluctuation range of 10%, frequency 50 +/- 0.5Hz).
3. Set the temperature and humidity parameters through the control panel, and you can choose the program mode or the fixed value mode to operate.
4. Start the equipment, monitor the actual temperature and humidity and program execution status, and remotely monitor if necessary.
5. After the test is completed, turn off the device and disconnect the power supply.
Notice
