Time cycles are part of the equipment design that have been accurately set in the factory and should
not be field adjusted. Timing changes are possible for custom applications but always consult the
factory prior to changes. The following are the standard time cycles for your equipment.

Drain Time Sequence
The standard heatless regenerative air dryer is controlled by a CMOS logic system designed
specifically for compressed air dryers. The controller is preset in its function with adjustments available
by moving jumper pins.
