6.
Quick press the CLEAN button to start the process. Ice machine will show a solid red and flashing yellow light
during the cleaning cycle.
7.
The machine will first verify that the sump is empty with the pump ON and the purge valve energized.
8.
When the sump is mostly empty, the machine will begin to fill the sump (about 30 seconds to a minute).
9.
The pump turns ON when the water fill reaches the proper fill level. Measure the appropriate amount of descaler
according to the machine size and sump volume from chart below. Carefully pour the descaler into the sump
using the lower curtain to prevent splash. Replace upper evaporator cover.
10. The machine will remain in the WASH cycle for 15 minutes.
11. After WASH time, the machine will PURGE and re-fill with the water pump ON.
12. The machine will RINSE (less than one minute) then repeat PURGE/FILL/RINSE multiple times.
13. The machine will end the cleaning cycle with a mostly empty sump and a solid red and yellow light.
14. Quick press the CLEAN button to return to OFF mode.
15. Remove the upper evaporator cover and lower evaporator curtain. Using a solution with the proper concentration
of cleaner (descaler or sanitizer), wipe down with a clean soft cloth the evaporator, water spillway, water
distributor, upper evaporator cover, lower evaporator curtain and all splash surfaces. Verify that all residue and
residual minerals have been removed.
16. If a full clean of water components is required, this can be done by referring to the service manual for water
system component breakdown. This is recommended to be done by a qualified service agent.
17. Re-assemble all ice machine water system components in reverse order.
18. Sanitizing the ice machine is recommended after descaling. Repeat the process with sanitizer at correct ratio.
19. It is recommended to clean (descale and sanitize) the storage means after cleaning the ice machine.
20. Quick press the POWER button to return the ice machine to the ice making cycle.
21. Replace the front panel and tighten the two panel screws with a Phillips screwdriver.
