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.
