Caution
The installation and layout of the circuit wiring must be performed by our professional qualified staff.
Please use the specified device component appointed by our company.
While the fan is running, please don’t cut off the power, otherwise it will cause damage to the fan. It should cut off
the power when the fan is drop-dead halt.
When the fan is in the corotation (inversion) state, please don’t switch the button to the opposite direction directly or
it will cause the mechanical failure.
8. Troubleshooting
Common causes for the malfunctioning operation:
1. The external power supply of the control box is not valid.
2. Open the master switch, and then turn on the three gears control switch, if the fan can still not work, please check
whether the speed knob is of the MIN state. Otherwise, please contract KaLe Environmental Technology(Shanghai)Corp.
Non-professional staffs do not open the electrical control box! For repair or adjustment, KaLe Environmental
Technology(Shanghai)Corp. will send you our trained professionals or engineers.
If you find the equipment is damaged or has abnormal sound, please stop running as soon as possible, cut off power
supply, and contact our service department.
Notes: Equipment damages due to the improper use are not covered by the warranty. Personal injuries and equipment
damages for your failure to comply with the contents of this manual, the Company will not bear any responsibilities.
