The use of the minimum speed ( 1 and 2 ) must be carefully evaluated by skilled personnel because the operation at
very low fan speed could result in malfunction or even damage to the unit.
It is recommended to move a single micro switch for each operating speed . The displacement of two or more micro
switches may generate incorrect power supply voltages with malfunction or damage to the unit .
