SPRINKLER CLEANING
NOTE: The sprinkler should only be cleaned when you find that some ice cubes are improperly shaped.
You should clean the ice making system after cleaning the sprinkler.
NOTE: DO NOT use solvent-based cleaning agents or abrasives on the interior. These cleaners may
transmit taste to the ice cubes or damage or discolor the interior.
1. Disconnect the power supply cord.
2. Open the door and remove the block water board by snapping one end up and pulling forward.
3. Remove the block water board from the evaporator.
4. Find the sprinkler arm and raise it. Disconnect it from the water tube which is connected at the back
of the sprinkler arm.
5. A de-scaling solution may be prepared in a plastic basin with Nu-Calgon Nickel-Safe Ice Machine
Cleaner. Mix four ounces of the ice machine cleaner per gallon of warm water.
6. Remove the sprinkler arm from the interior. Thoroughly clean the sprinkler arm by soaking it in the
basin filled with the de-scaling solution until it is free of any deposits. Use a soft brush to remove any
thick or stubborn residue to help the dissolving action. Rinse under a stream of tap water.
7. Wipe down the interior of the water sump with the de-scaling solution and warm water. Rinse
thoroughly with clear water.
8. Reassemble the sprinkler arm, evaporator and block water board.
9. Perform steps 1, 3-5 of the Ice Making System Cleaning procedure detailed below.
ICE MAKING SYSTEM CLEANING
1. Unplug the ice maker ensuring the water connection remains intact.
2. Open the door of the top cabinet, and making sure there are no ice cubes on the evaporator, remove
all ice cubes from the ice storage bin.
3. Remove the water box and dispose of any water before reinstalling. Then, fill the ice maker cleaner
into the water box. Plug in the unit and press the clean button (5 seconds). The machine will
automatically go into cleaning mode which lasts for 30 minutes. At the same time, clean the ice
storage bin with the cleaner.
4. After the ice maker completes the cleaning mode, remove the water box, drain the water, clean the
water box and evaporator cover according to the instructions in this manual (see step 6 below).
Lastly, reinstall the water box, press the clean button (5 seconds) to begin the water cycle mode and
clean all residual cleaning solution.
5. Repeat the process detailed in step 4 three times to ensure the cleaning solution has discharged
completely.
6. After completing step 5, remove the water box and evaporator cover. Clean these parts with water
between 95-122°F (35-50°C). Flush and clean the inner liner of the ice storage bin.
7. Once you have completed the above processes, throw away the ice cubes.
