Air curtain fault diagnosis and maintenance
The diagnosis of the air curtain mainly targets the fan inside, which is a device for blowing or exhausting air. A blower is a fan that blows air into ducts, pressure spaces, rooms, or other areas. An exhaust fan is a fan that sucks air out of a room.
First, check the materials outside the unbalanced fan. Many repairers will find that something is stuck to the fan frame. Repair note: Remove these items and check for damage.
Secondly, the fan's transmission volume exceeds the rated value. Repair instruction: Reduce the fan speed.
Finally, the fan speed is too high or the rotation direction is incorrect. Repair instruction: Reduce the fan speed or correct the fan's direction.
Installation precautions for the air curtain:
1. Optimal installation height: Determine the installation height based on the selected model.
2. The machine must be installed securely and level; vertical or tilted installation is not allowed, and no debris should fall into the machine.
3. The installation of the machine should be based on the size of the door and heating requirements, selecting one or more units, generally requiring the total length of the machine to be slightly wider than the door.
4. During the initial test run, no one is allowed under the machine.
5. If there are abnormal sounds during use, stop the machine immediately for inspection.
Daily maintenance of the air curtain:
1. Check the air inlet and outlet of the air curtain to prevent blockage
2. Check electrical components, check if screws are loose and if connections are secure
3. Check if the hanging bolts of the air curtain are loose,
4. Check if the power line of the air curtain is aging
