3. Removal and Replacement of Auger

1) Move the power switch to the "OFF" position, then unplug the unit from the electrical
outlet.
2) Close the water supply line shut-off valve.
3) Remove all ice from the storage bin.
4) While maintaining a hold on the door, remove the hinge stop pin from hinge (B). Pull out
the bottom of the door slightly, then gently remove the door from hinge (A). See Fig. 10.
5) Remove the top panel.
6) Remove the spout.
7) Remove the upper rear panel. See Fig. 12.
8) Remove the clamp securing the drain plug, then lower the drain hose into a container.
Remove the drain plug to drain the water from the reservoir and evaporator assembly.
9) After all of the water has drained, replace the drain hose, drain plug, and drain clamp in
their original positions.
10) Remove the packing.
11) Remove the socket head cap screws securing the extruding head and evaporator flange.
Remove the evaporator flange, then grasp the cutter and carefully lift out the cutter and
extruding head. Grasp the top of the auger and carefully lift out the auger.
12) When pulling out the auger, the upper part of the mechanical seal should come out with
it. The mechanical seal consists of two parts. One moves along with the auger, and the
other is fixed on the lower housing. Inspect the part of the mechanical seal that came
out with the auger. If the contact surface on the bottom of the seal is worn, cracked
or scratched, the mechanical seal may cause water leaks and both the upper and
lower parts of the mechanical seal should be replaced. Instructions for removing the
mechanical seal are located later in this procedure.
13) Remove the mechanical seal from the old auger and place it on the new auger.
14) Install the new auger. Replace the cutter, extruding head, and evaporator flange in their
correct positions.
