To Reprogram the Automatic Flushing Timer:
The flushing timer is set at the factory to flush the humidifier every two hours for
a duration of 10 seconds, using approximately 1.5 gallons of water per day.
Although the two-hour intervals between flushes may not be altered, the dura-
tion may be lengthened to either 20 or 30 seconds per flush.
1. Unplug the flushing timer from the electrical outlet.
2. Take off the back cover plate by removing the three screws closest to the
moutning flanges.
3. Inside, on the circuit board, locate the red switch block which contains two
switches, numbered 1 and 2.
NOTE
: The switches are pre-set in the 10-second mode, with
the #1 switch in the ON position, and the #2 switch in the OFF
position, as shown at right.
4. To reprogram the flushing timer to 20-second flushes
every 2 hours, move the #1 switch to the OFF position, and
the #2 switch to the ON position, as shown at left. At this
setting, the automatic flushing timer will use approximately 3
gallons of water per day.
5. To reprogram the flushing timer to 30-second flushes every
2 hours, move both switches to the OFF position, as shown at
right. At this setting, the automatic flushing timer will use
approximately 4.5 gallons of water per day.
6. Reposition the back cover plate on the flushing timer and secure it with
the three screws.
7. Plug the flushing timer back into the wall outlet. Make sure it is functioning
properly with the humidifier. (See Step #12, page 14.)
NOTE
: Lengthening the flushing duration will help keep the humidifier
cleaner. However, it may also cause undesirable drain noise.
