Operating precautions
Storage temperature
There is no performance problem when the system is used at between -30℃ and +70℃. There is a possibility that same problem of lubri-
cant and insulation inside motor might occur by condensing due to rapid surrounding temperature change. Therefore, please take care
of non-condensing using desiccant or something during fan is in storage.
Tightening Torque
Comparison of ribbed and ribless structures
Regarding plastic frame, we have a option ribbed and ribless about mounting. Please use preferred type up to your application. Please
use ribbed fan in case that you hook fan up clamping either side fan mounting hole target. (Ribless type of some models aren't avail-
able.)
*Use a fan with a rib structure when using a screw for piercing.
*The plastic frame models of DC fans are classified into ribbed models and ribless models based on the shape of the installation
・When securing screws to ribless plastic frame models, use a flange to secure on one side.
Handling precautions
Sanyo Denki's fans incorporate precise bearings. Therefore, please handle the motors carefully in order not to shock the bearings.
Operating precautions
section of the frame.
This shows the recommended values for the tightening torque
when installing the fans. If the tightening torque is higher than the
recommended values, the fan can be deformed or damaged.
Use care when tightening. Also, be sure to always use a fan with
a ribbed structure when using screws to pass through and secure the fan.

Installation
There are no limitations on the installation direction of AC
fans, DC fans, or blowers. AC/DC fans have symbols on the
fan motor indicating the airflow direction and blade rota-
tion direction. When installing, use these symbols to check
the airflow direction.
