12. Turn bin stat adjustment screw clockwise until it stops. Then turn it counterclockwise 1/8 of a turn.
13. Reinstall the front cover of the electrical box and the ice machine and reconnect the power. Verify
that the Bin Stat is working by holding ice on the coiled bare capillary tube. The bin stat will allow the
ice machine cycle to complete and harvest ice. Then the ice machine will shut down. Remove the ice
from the capillary tube and warm the tube with hand heat. The ice machine should start in approxi-
mately 60 seconds.
