Operation
Set the device to the correct voltage before starting up the ventilator. (230V is pre-set)
Connect the device to a suitable, earthed socket and turn switch A to ON. Check
correct operation, before the unit is left unsupervised. Do not move or carry the
ventilator during operation. Pay attention to the direction of air flow. It is marked by an
arrow B on the housing.

If the device is to be connected to a 115V mains supply, the voltage selector switch
must be re-set to the appropriate voltage. Loosen the safety screw C with a slotted
screw driver for this purpose and then re-set the switch to the desired voltage range:
