1. The usage environment should be kept clean regularly, the surface of the fan should be kept clean, there should be no debris at the inlet and outlet, and dust and other debris inside the fan and pipeline should be removed regularly.
2. The fan can only be operated under normal conditions, and the power supply facilities must have sufficient capacity and stable voltage. It is strictly prohibited to operate with defects. The power supply line must be a dedicated line and temporary lines should not be used for long-term power supply.
3. During the operation of the fan, if abnormal sounds are found, the motor is severely overheating, the casing is electrified, the switch trips, and the fan cannot be started, it should be stopped immediately for inspection. To ensure safety, maintenance is not allowed during the operation of the fan. After maintenance, a trial run should be conducted for about five minutes to confirm that there are no abnormal phenomena before starting the machine.
4. According to the usage environment conditions, lubricating grease should be supplemented or replaced irregularly for the bearings (motor enclosed bearings do not need to replace lubricating grease during their service life). To ensure good lubrication of the fan during operation, the refueling frequency should not be less than 1000 hours per time for the enclosed bearings and motor bearings. ZL-3 lithium based lubricating grease should be used to fill 1/3 of the inner and outer rings of the bearings during refueling; It is strictly prohibited to operate without oil.
5. The fan should be stored in a dry environment to prevent the motor from getting damp. When storing fans outdoors, there should be defensive measures in place. During storage and handling, the fan should be protected from collision to prevent damage.
