    12. Re–assemble. steps 6 through 10. CAUTION: IN RE–ASSEMBLING THE AUGER GEARMOTOR, THE HOLD DOWN CLAMPS MUST BE TIGHT AND SECURE. IN RE–INSTAL- LING THE EVAPORATOR SHELL, BE ABSO- LUTELY SURE THAT THE “O” RING IS NOT PINCHED OFF AS THIS WOULD CAUSE A WA- TER LEAK AROUND THE BASE OF THE EVAP- ORATOR.

  • Page 20: Cuber Sanitizing And Cleaning Procedure

    Add 1/2 oz. “sanitizer” to a gallon of lukewarm wa- ter. With a non–metallic bristle brush, scrub the inte- rior of the ice bin including the under side of the door, and the outside of the ice chute that protrudes into the ice bin.

  • Page 22: Adjustment For Ice Bridge Thickness

    ADJUSTMENT FOR ICE BRIDGE THICK- NESS An ice bridge connecting all cubes is necessary for a proper harvest of discharge of cubes from the evaporator. To increase ice bridge thickness carefully turn adjustment screw counter-clockwise no more than one turn at a time. Wait and check thickness before re-adjusting.

  • Page 23: Checkout Procedure For Harvest Bin

    CHECKOUT PROCEDURE FOR HARVEST BIN SWITCHES Turn on the ice machine and move the evaporator curtains(s) away from the evaporator(s). The ice machine should then shut off in approximately 8 seconds. (see detail A). Slowly let the evaporator curtain(s) move back toward the evaporator(s) until the bottom edge of the curtains(s) is at least at the bent edge of the water reservoir or closer to the evaporator.
