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.
