2. Cleaning Procedure
1) Turn off the power supply, then remove the front panel. Make sure the power switch is
in the "ON" position, then move the control switch to the "DRAIN" position. Replace the
front panel in its correct position.
2) Close the icemaker water supply line shut-off valve.
3) Turn on the power supply and allow the water system to drain for 5 minutes.
4) Turn off the power supply, then remove the front and top panels. Move the power switch
to the "OFF" position.
5) Remove all of the ice from the storage bin.
6) Remove the strap connecting the spout to the chute assembly, then remove the spout.
See Fig. 6.
7) Pour the cleaning solution over the extruding head until the evaporator assembly and
the reservoir are full and the solution starts to overflow into the drain pan.
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 reservoir and evaporator assembly to block flow. Pour additional cleaning
solution over the extruding head until the evaporator assembly is completely full.
8) Replace the spout and strap in their correct positions.
9) Allow the icemaker to sit for 10 minutes before operation. If you placed a clamp on the
reservoir hose in step 7, remove it before operation.
10) In bad or severe water conditions, clean the float switch assembly as described below.
See Fig. 7. Otherwise, continue to step 11.
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.

position. Replace the panels in their correct positions. Turn on the power supply and
make ice using the solution until the icemaker stops making ice.
12) Turn off the power supply, then remove the front panel. Move the control switch to the
"DRAIN" position, then replace the front panel in its correct position.
