5. Allowing the dryer to operate for two complete cycles ensures that the probe will not

be exposed to high humidity and damaging liquid water. This is especially important

when dryer has been stored or sitting idle for several months.

6. After this period, slowly open the DDS sample valve so that a small flow of air

passes across the probe (approximately 2 to 3 SCFH). This valve should be open at

all times when dryer is in operation.

7. Now turn the auto/manual selector switch to the “auto” position. The DDS

operational light will come on to provide indication that the Dewpoint Demand

System has been activated.

NOTE

IT IS RECOMMENDED THAT THE DRYER BE OPERATED IN THE MANUAL

MODE FOR A PERIOD OF 4 TO 6 MONTHS WHILE DESICCANT AGING

OCCURS.

2. Failure to Shift Alarm (FTSA)

A. The Failure to Shift Alarm monitors tower shifting and energize an alarm light on the

front panel of the control box should the regenerative dryer fail to cycle.

B. Should dryer fail to cycle because of malfunction of a system component the FTSA light

will be energized. Should FTSA alarm light be observed, refer to “Troubleshooting

Guide” and reset the alarm.

3. High Humidity Alarm (HHA)

A. The High Humidity Alarm monitors the outlet moisture condition and energizes an alarm

light on the front panel of the control box should the regenerative dryer fail to provide

proper dewpoint performance.

B. Should dryer dewpoint elevate because of malfunction of a system component, overflow

condition, oil contamination, or desiccant attrition, the HHA light will be energized.

Should alarm light be observed, refer to “Troubleshooting Guide”.
