the lowest water level. The Display will exit the
menu option and go into FILLING TANK mode.
The Tank Level is now calibrated.
NOTE: If the Display remains in the menu option and the highest tank level is
blinking, then the tank level was not calibrated. The amount of water emptied
from the tank was not enough (less than 10%). The tank needs to be emptied
to its lowest water level. Allow the tank to fill to the 100% level and perform
the calibration again.
