6.3 Adjustment of Air Intake & Exhaust Dampers for Model DC / DCW
Adjustable air intake and exhaust dampers permit the air circulation system to be operated between a one-
pass airflow system and a full recirculated airflow system. Both dampers should be slightly opened for
the following conditions.
To remove undesirable process moisture and vapors generated by the heating process.
To promote faster drying times.
When operating near ambient temperature.
Cooling with the heating system turned off.
The blower wheel generates additional heat due to air friction as it rotates at high speed. This additional
heat can not be controlled by the main temperature controller. Both dampers should be opened wider as
you operate closer to ambient temperature to purge the extra heat produced.
Standard Air Intake Damper: The intake damper
includes a pivot assembly with a linkage to the damper
blade. You must loosen the knob to slide the pivot
assembly right or left, which opens and closes the damper.
A damper setting scale is indented into the frame. It is
marked “Closed, 1, 2, 3, Open”. Make sure you tighten the
knob after changing the setting.
Note: The indented scale is marked for reference only.
There is no related unit of measure tied this scale.
