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.
Maintenance
The HumidiClean is designed to minimize maintenance. As stated in the PRINCIPLE OF OPERATION
section, after the HumidiClean has accumulated 90% of the selected Service Life, in hours of heater
on time, the "STATE" LED will flash (blink) in yellow. At this time the ionic beds in the tank should be
replaced. If service is not performed, the unit will continue to operate for the remaining hours before
shutting down completely.
Note: Service Life can be adjusted based on water quality. If Ionic Beds are relatively free of scale
deposits or scale is forming on tank walls and elements because beds are saturated with scale, please
consult the factory for Service Life adjustment procedures.
Replacing 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.
