4. Operation instructions
Operation Instructions
1. Please read the precautions very carefully before you start use.
2. Please confirm the wirings have been connected correctly, then
turn the main knob to “ON”. Now it’s powered on.
3. Press twice “start speed switch” to use “start speed switch” to
control the rotation speed.
4. Press twice “rotation button” to stop the motor. Then turn the
main knob to “OFF” the rotation completely stop.
5. You can also achieve the operation guide by scanning the QR
code.
5. Safety precautions
Do not bend the fan blades when installing, adjusting, and cleaning the fan, otherwise it will damage the equipment or affect the use of the equipment.
Before turn on the power please make sure that the input voltage of the fan is consistent with the power supply voltage.
Do not operate maintenance when the power is on.
Please correctly connect the input and output power cables and ground cables according to the markings on the control box.
After confirming that the wiring is correct, the product is energized for trial operation. After the trial operation is correct, it can run normally for a long
time.
If the fan fails and cannot be reset, please contact the manufacturer.
Do not operate the damaged equipment, otherwise it will bring unexpected and serious consequences.
It is strictly prohibited to run the fan when the safety space is insufficient.
It is strictly forbidden to work inside the fan operating space. Please confirm whether there are obstacles before turning on the fan.
It is recommended that before the machine is powered off, please press the "knob key" to stop the machine, and turn off the power after the device has
completely stopped rotating.
If the machine has not been used for more than 2 months, please pre-charge the product when it is used next time: Turn on the power and waiting more
than 15mins to start the rotation.
Warning: Before operation please read the manual very carefully. Remove obstacles in the operating area to ensure
that the fan runs with safe distance. Before operate any maintenance please make sure you already turned off the
power supply. The operation must be done by professionals to avoid being injured.
Attention
1. Make sure that there are no obstacles and potential hazards in
the fan operating space.

Warning!
The installation and circuit wiring work must be operated by professionally qualified person. Please use the device parts specified by our
company. Do not cut off the power supply while the fan is running, otherwise the fan will be damaged. The power should be cut off after the
fan completely stopped. When the fan is running, do not turn the knob directly to the reset position. Otherwise it will cause mechanical failure.
6. Failure recovery
Common reasons for the fan not working properly:
1. The external power supply of the control box is invalid.
2. If you turn on the main switch but the fan still does not run please contact KALE Environmental Technology (Shanghai) Co., Ltd. to
communicate with our professional engineers.
Non-professionals are strictly prohibited from opening the controller box! If maintenance or adjustment is required, the operation must be
performed by professionals trained by KALE Environmental Technology (Shanghai) Co., Ltd. or under the guidance of our company's engineers.
If you find any damage or abnormal noise, please stop the operation as soon as possible, cut off the power, and contact KALE after-sales
service department. Note: Equipment damage caused by abnormal use is not contained by the product warranty of KALE FANS. Our company
shall not be liable for personal injury and equipment damage caused by your failure to comply with the contents of this manual.

9. Repair and maintenance
Our product design is maintenance-free, but in order to ensure the fan's long life and normal operation, the fan should also be
maintained, especially for applications in harsh environments. For any maintenance on the fan or inverter controller, please
make sure that the fan stops running and cut off the power supply of the controller to protect personnel.
Time interval -Recommended maintenance work content
Trial run -Check the fan for abnormal running sound or vibration
Every 2500 hours of work -Frequency conversion controller dust removal
-Fan blade dust removal
Every 5000 hours of work -Check mechanical fasteners to ensure that there is no looseness
-Check the wire cable to make sure there is no damage
If the fan produces severe noise or vibration during abnormal operation, it indicates that a mechanical part is damaged. At this
time, it should be shut down immediately and a thorough inspection should be done.
