5)Remove all ice from the storage bin.

6)Remove the slope from the storage bin by carefully bending it in the center and releasing it from the 2 slope shafts.

7)Remove the scoop. Remove the 2 thumbscrews securing the scoop holder, then remove it.

8)Remove the screws securing the upper rear panel, then remove it.

9)Remove the clamp securing the drain plug, then lower the drain hose into a container. See Fig. 16. Remove the drain plug to drain the water from the evaporator assembly and reservoir.

10)After all of the water has drained, replace the drain plug in its correct position.

11)Remove the spout. Pour the cleaning solution over the extruding head until the evaporator assembly and the reservoir are full and the solution starts to flow through the overflow hose. Replace the spout in its correct position.

Note: If there is excess scale on the extruding head, fill the evaporator assembly and reservoir as described above, then use a clamp on the reservoir hose between the evaporator assembly and reservoir to block flow. Pour additional cleaning solution over the extruding head until the evaporator assembly is completely full. Replace the spout in its correct position.

12)Allow the icemaker to sit for 10 minutes before operation. If you placed a clamp on the reservoir hose in step 11, remove it before operation.

13)In bad or severe water conditions, clean the float switch assembly as described below.

Otherwise, continue to step 14.

a.Remove the float switch assembly from the reservoir cover.

b.Wipe down the float switch assembly with the cleaning solution.

c.Rinse the float switch assembly thoroughly with clean water.

d.Replace the float switch assembly in its correct position.

14)Plug the unit back in. Move the power switch to the "ON" position.

15)Allow the unit to make ice using the solution. When ice stops coming out, move the power switch to the "OFF" position. Unplug the unit from the electrical outlet.

16)Remove the drain plug to drain any remaining solution.

17)After all of the solution has drained, replace the drain plug in its correct position.

Note: If you do not sanitize the icemaker, go to step 9 in "IV.B.5. Sanitizing Procedure - Final."

18)Remove the spout. Using a clean container, pour water over the extruding head until the water starts to flow through the overflow hose.

19)Remove the drain plug to drain the water.
