To prevent electric shock, make sure to use the ground wire.
When removing the electrical plug, do not touch any conductive parts.
If the motor operation suddenly stops, proceed according to the following
instructions.
①Turn off the power source.
②Confirm wire connections and remove any garbage and dust from the
intake side. (Do not dissemble).
③Confirm that the motor temperature has decreased.
④Reconnect power. Automatic recovery and operation will commence anew.
Overloading while operating this machine (for example, locking the
impeller), fluctuating temperatures, or changes in atmospheric pressure can
lead to fluctuations in the motor temperature. Continuing operations under
these conditions will reduce the life of the motor internal parts. Depending
on the situation, the motor may burnout, and cause a fire.
Built-in protection will protect the motor from such occurrences. The built-
in protection has a temperature sensor which, should the motor become too
hot, will stop motor operation and automatically resume operation once the
temperature has gone down.
If any of the following occurs, immediately unplug and cease operation.
There is a risk of fire or smoke.
•Even after the switch is on, the impeller does not turn.
•The impeller rotation slows or becomes abnormal.
•There is a burning smell.
•The motor hums, rumbles, or emits other abnormal sounds.
