Sanitizing
10) Confirm the mode switch is in the "CLEAN" position, then move the control switch to the
"ON" position (1 short beep occurs, then 3 seconds later 1 long beep occurs).
Replace the front panel. The water tank drains and then fills.
11) When the control board starts beeping (2 beep sequence), remove the front panel.
Move the control switch to the "OFF" position.
12) Remove the front insulation panel, then pour 0.6 fl. oz. (18 ml) of an 8.25% sodium
hypochlorite solution (chlorine bleach) into the water tank. Replace the front insulation
panel. IMPORTANT! Use regular bleach with no additives. Using a bleach with
additives causes excessive foaming during sanitizing, reducing the effectiveness
of sanitizing.
13) Move the control switch to the "ON" position (1 short beep occurs, then 3 seconds later
1 long beep occurs). Replace the front panel. To avoid excessive foaming in the water
tank, there is a 1 minute delay before circulation begins. After approximately 30 minutes
of circulation, the icemaker performs 3 rinse cycles.
14) When the control board starts beeping (5 beep sequence), remove the front panel.
Move the control switch to the "OFF" position.
15) Clean the dispenser unit/ice storage bin liner using a neutral cleaner. Rinse thoroughly
after cleaning.
16) Move the mode switch to the "ICE" position, then move the control switch to the "ON"
position. Note: If on a dispenser unit, turn on the dispenser unit power supply.
17) Replace all panels in their correct positions.
