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. 14. Remove the drain plug to drain the water from the reservoir and evaporator assembly.

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

11)Remove the reservoir cover. Pour the cleaning solution into the reservoir until the solution starts to flow through the overflow hose. Replace the reservoir cover in its correct position.

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

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 and replace the spout in its correct position.

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

14)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.

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

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