Note
The fan should be cleaned with a suitable cloth or brush, and steps should be taken to
prevent moisture from entering the motor.
● Once the voltage has been disconnected on all poles, wait for five minutes before
touching the device.
● Never open the device during operation.
● Never loosen any fixing screws for the ventilation unit during operation.
● To clean the fan, remove the guard from the ventilation unit. The motor does not need to
be separated from the guard.
● Once you have finished cleaning the device, screw the guard (with fan) back on to the
ventilation unit. When doing so, tighten the four screws to a torque of 4 Nm.
