VI. RDU OPERATION
Upon starting the Herrtronic unit, the RDU fan will be
energized. If airflow is not sensed within ten seconds, the
Herrtronic unit will shutdown and a fault will be registered.
Depress ‘”Fault” button to confirm fault condition and clear
fault by pressing “Enter” and then “Back” button to return
to Menu 1.
Once operating, the fan speed can be adjusted continuously
from 1—5 (slow—fast) by turning the fan speed control
knob. Refer to the chart below for the optimum fan speed
setting for your application.
When the Herrtronic unit is turned “off”, either by switch
or controller, the RDU fan will continue to operate for 15
minutes to prevent the formation of condensate inside the
cabinet. The steam plume direction can be controlled both
horizontally and vertically by adjusting the louvers on the
air discharge grille.Louvers adjusted as shown in Figure
12 produce the most consistent and shortest evaporation
distance.
