RESETTING OF LEVEL SENSORS
OPENING THE UNIT
Remove the power cord from the unit and pull at least one battery from the battery holder. Remove all the solution tubing from the tubes on the back of the unit. Unscrew the 4 screws holding the BODY to the base (2 on right side and 2 on left side). Lift up on the right side of the BODY so that it hinges on the left side. Rest the BODY on its left side. (Like you are opening a book). VERY IMPORTANT - COVER THE CIRCUIT BOARD WITH A TOWEL SO IT DOES NOT GET WET. DO NOT PULL BODY STRAIGHT UP.
ADJUSTING THE LEVEL SENSORS
Locate the 5 level sensors on the heat tank. The sensor closest to the left corner is low level (4 oz. - 120 ml) followed by 7 oz, 4 oz, 7 oz and 7 oz pour the proper amount of water (start with 4 oz then add 7 oz etc.) into the heat tank. Hold the sensor where it passes over the tank wall with one hand and bend the end of the sensor with the other hand so that the sensor just touches the water. Empty the tank by closing the unit and running DRAIN.
DRAIN
Close unit. Reattach dump lines. Turn unit on. Push plus button until "DRAIN" appears in display. Press start.
