Overheat protection
The fan uses a thermal protector for overheat protection. Once the
temperature reaches a specified level, the internal thermal protector
that has an automatic-return feature is triggered to stop the fan
operation.
Be sure to turn off the power when checking the thermal protector.
Operating temperature of thermal protectors
Open (Power OFF) .........130±5 °C (266±9 °F)
Close (Power ON) ..........82±15 °C (179.6±27 °F)
