5. Operation
5.1 Precautions when starting the fan
(1) Turn the unit ON and OFF once or twice to confirm that the unit is operating normally without
any unusual noise or vibrations.
(2) Turn ON the fan, and operate it at full speed.
Check for any vibrations or noise at each section of the fan.
In addition, check that the motor current value is normal.
Note that the (electrical) current value becomes higher when the temperature of flowing air
is lower than the room temperature.
5.2 Precautions during the operation
Warning
In the event of a power failure, be sure to turn off the main power.
Otherwise, when the power is restored, the fan suddenly starts, and
it is dangerous.
(1) Frequently starting and stopping the fan quickly damages it.
As a guide, limit the startup frequency to about six times per hour.
5.3 Precautions when stopping the use
Warning
When you leave the fan unused for a long period of time, be sure to
turn off the main power.
(1) Protect the motor against moisture.
(2) Before you run the fan after a long time of nonuse, inspect each part.
