Safety Precautions for All Axial Fans

Do not touch the blades. Doing so may result in injury.
Always mount the optional Finger Guard when there is any possibility that a person may touch the fan blade.

Do not use the Box Fan with the Finger Guard removed.

Make sure that power is turned OFF before performing any action that requires touching the blades, such as inspections or filter replacement.

Do not hold the Fan by its power lines, or pull the power lines with excessive force. Injury may occasionally occur if the Fan falls.

Do no insert objects into the rotating parts of the Fan. Fan failure may occasionally result in property damage or minor injury.

Do not allow the Fan to be subjected to shock, such as falling, otherwise the service life and performance characteristics of the Fan will be adversely affected. Precision-type ball bearings are used to hold the shaft of the Fan.

Do not use the Fan outside the rated temperature range or above the rated voltage. The resulting increase in coil temperature or blade deformation may occasionally cause burns or other minor injuries. Do not touch the motor section during operation or immediately after stopping operation.

Do not use the Fan in locations subject to flammable or explosive gases. Minor injury may occasionally occur due to explosion.

Do not attempt to disassemble, repair, or modify the Fan. Property damage or minor injury may occasionally occur due to electric shock, fire, or Fan failure.

Unexpected operation of the Fan after, for example, the Fan has stopped due to contact failure or due to the operation of overheating protection (thermal protection), may result in minor injury.
Make sure that the power is turned OFF before performing any action that requires touching the blades, such as inspections.

Do not wire the power lines of the Fan in series with those of other Fans or devices. Wire the devices in parallel. Fan failure may occasionally result in property damage or minor injury.

Be sure to secure the Fan with the mounting bolts. Not doing so may result in injury due to the Fan falling. Use M4 bolts to mount the Fan. Recommended tightening torque: 0.44 Nm.

Provide measures, such as circuit-breaker fuses, on the power supply lines of devices that are using Axial Fans. Short-circuiting of the Fan may adversely affect other devices.

Precautions for Safe Use

Do not install the Fan in the following locations.

Locations subject directly to water (except for water-resistant Fans)

Locations subject directly to oil

Locations subject directly to vibration or shock

Locations subject to strong static electricity or harmonics

Locations subject to excessive dust or metallic powder

Locations subject to direct sunlight

Locations subject to condensation or icing

Locations subject to corrosive gases (particularly sulfide and ammonia gases)

Precautions for Correct Use

1.Check the direction of the airflow before installing the Fan. The direction of the airflow is indicated with an arrow on the Fan frame. The arrow points in the direction that the air flows.

2.Refer to the panel cutout dimensions in each datasheet to cut a hole in the installation device and secure the Fan with bolts.

3.The Fan is intended for cooling and air circulation. Do not use it for other purposes.

4.Dispose of the Fan as industrial waste.

5.Ensure that no organic solvents or alkaline chemicals are in contact with plastic parts of the Fan, otherwise cracks, swelling, or dissolution may result.

6.Secure the cover of the Box Fan with the mounting bolts. If the cover is loose, vibration may cause it to come off.

7.Do not remove the cover while the Box Fan is operating.
