4. Removal and Replacement of Auger
1) Drain the water from the evaporator.
a) Remove the front panel, then move the power switch to the "OFF" position.
b) Move the control switch to the "DRAIN" position.
c) Move the power switch to the "ON" position and allow the water to drain from the
evaporator.
d) Move the power switch to the "OFF" position, then turn off the power supply.
2) Remove the top and side panels.
3) Remove the strap connecting the spout to the chute assembly, then remove the spout.
4) Remove the extruding head seal bolts. Using the cutter, lift out the auger assembly.
5) Remove the cutter bolt (if applicable), cutter, washer (if applicable), and dowel pin (if
applicable). Remove the extruding head from the auger and place on the new auger.
6) Install the new auger.
7) Replace the removed parts in the reverse order of which they were removed.
Note: Be sure to use new seal bolts. See "Seal Bolt Removal and Installation
Instructions" above.
8) Replace the top and side panels in their correct positions.
9) Move the control switch to the "ICE" position.
10) Move the power switch to the "ON" position, then turn on the power supply.
11) Replace the front panel in its correct position.
5. Removal and Replacement of Evaporator
IMPORTANT
Always install a new drier every time the sealed refrigeration system is opened. Do
not replace the drier until after all other repair or replacement has been made.
1) Drain the water from the evaporator.
a) Remove the front panel, then move the power switch to the "OFF" position.
b) Move the control switch to the "DRAIN" position.
c) Move the power switch to the "ON" position and allow the water to drain from the
evaporator.
d) Move the power switch to the "OFF" position, then turn off the power supply.
2) Remove the top and side panels.
3) Recover the refrigerant and store it in an approved container.
4) Remove the strap connecting the spout to the chute assembly, then remove the spout.
5) Disconnect the water hoses.
6) Remove the extruding head seal bolts. Using the cutter, lift out the auger assembly.
7) Remove the insulation and the expansion valve bulb on the suction line.
8) Disconnect the inlet and outlet tubing.
