End of Season Drain
If at any time during normal operation there is not a demand for a continuous 72 hour period,
HumidiClean drains the tank and the PC Board initiates a drying cycle by cycling the heating elements
for short intervals in order to dry the ionic beds.

1. Save the settings, consult the OPERATION SETUP menu
2. Go to Steam Gen. Menu
a. Drain tank by operating menu from “STEAM GEN.” to “MANUAL DRAIN” position.
b. Once the tank is drained, shut power off to unit and allow the tank to cool.
c. Remove the cabinet access panels, and slowly open tank access panel.
3. Unsnap ionic beds from support pins and slide them out through the access opening.
4. Inspect tank drain screen and elements inside the tank. The elements should appear to be flaking
off scale. If the drain screen appears to building deposits in the screen holes it should be cleaned.

support pins. (Pinch ends to secure.)
