1. Press the “F” and “G” buttons at the same time for 3 seconds, the “C” LED will start to
flash, and the illuminated LED on the “E”(Dew Point Temperature Indicator) LED will
identify the factory setting for “On Time”. (See table)
2. Press and release the “F” button to sequence from left to right until reaching your
selection. The “Red” LED is not used.
3. To store the On time and set the Off time, press the “G” button and set as step 2.
4. Exiting the Program will cause the Timer Drain to discharge and begin a new cycle.
Note: Failure to perform step 3 within 10 seconds of completing step 2 will cause the unit
to revert back to the previous setting.
* Operating check points
Check the following on a periodic basis:
A. Green power on light is illuminated.
B. Dewpoint indicator is in green area.
C. Condensate is discharging from drain.
Electronic Drain Valve Adjustment
To minimize air losses, the drain valve control time should be adjusted to open the drain
port just long enough to discharge accumulated condensate. Set the drain valve operating
time so that only air discharges at the end of the open period. Recommended initial
settings are a 1 to 2-second drain opening and 30 seconds drain closed time (cycle). If
liquid discharges as the port is closing, set the timer for a shorter cycle or a longer opening.
