3.  Locate DIP switch SW201 {FUNCTION} on the right circuit board.

5.  Slide the chassis back into the control module's housing. 

6.  Cover the °F label with the °C sticker included in the information packet. 

 

1.  350 - 2100 cfm dryers shift air flow from the on-line desiccant bed to the regenerated desiccant 

bed based on actual dewpoint demand, not by fixed time cycles. 

2.  Set the Dewpoint Shift Point to the highest process air moisture content you would like to allow 

before the dryer shifts air flow to the regenerated desiccant bed. 

3.  The Dewpoint Shift Point is set with the dewpoint meter, the Push To Set push-button, and the 

Dewpoint Shift Adjust potentiometer [pot]. 

1.  Carefully loosen the locking hex nut on the Dewpoint Shift adjust pot. The pot is just below the 

dewpoint meter.  

2.  Press and hold the Push To Set push-button next to the Dewpoint Shift Adjust pot.  

3.  With a small screwdriver, adjust the Dewpoint Shift Adjust pot until the dewpoint meter reads 

the highest acceptable process air dewpoint. This is the point that airflow will be shifted from 
the on-line bed to the regenerated bed, providing the regeneration cycle has been completed.  

4.  Release the Push To Set push-button and re-tighten the locking nut on the Dewpoint Shift 

Adjust pot.  

 

5.  Reconfirm the Dewpoint Shift Point by pressing the Push To Test push-button.
