5.0 SETTING THE UNIT SPEED / ROTATION
The speed selector is located on the PCB (see figure 14). The unit has a
choice of three speeds to suit the size of the dwelling and the moisture
being generated. The unit is factory set at No. 3 - High Speed. We
recommend that the unit is operated at this speed and the setting
reduced if and when necessary in the future.
Replace PCB cover and test the unit. Check rotation of fan with
diagrams under airflow direction. If direction is incorrect, isolate
the unit, remove PCB cover and alter the fan rotation jumper block
(mounted on the PCB). Replace PCB cover and re-check direction of fan.
Replace filter and front cover.
