  2. Cleaning the inner cabinet and ice scoop with diluted detergent, warm water, and a soft cloth.
  3. Draining the cleaned water from the water tank and the main drain port.
  4. Discarding the first batch of ice cubes produced after cleaning.

Water Drainage

The unit has two drainage points:

  • Back drainage port: For draining water from the ice storage bin using the white drainage pipe.
  • Water tank drain pipe: A silicone pipe on the right side of the water tank (indicated by "H" in illustrations) can be pulled out to drain cleaned water from the tank.

Exterior Cleaning

The door and cabinet should be cleaned regularly with a mild detergent solution (28g dish soap in 7.5L warm water) and a soft cloth. Abrasive cleaners and solvents should be avoided. The side steel plate, if discolored by chlorine gas, should also be cleaned with a mild detergent.

Interior Cleaning (Ice Storage Bin)

The ice storage bin should be sanitized occasionally, especially before first use and after extended periods of inactivity.

  1. Disconnect power.
  2. Wipe the interior with a sanitizing solution (28g household bleach/chlorine in 7.5L hot water).
  3. Rinse thoroughly with clear water, allowing waste water to drain.
  4. Reconnect power. The ice scoop should be washed regularly like any other food container.

Ice Making Parts Cleaning

This involves cleaning the water tank and the water dividing pipe on the evaporator. If water flow from the dividing pipe is minimal or absent, it indicates a blockage.

  1. Clean the water tank and other inner parts.
  2. For the water dividing pipe, pull it up and move it out to clean any obstructions in its eight small holes. Reinstall it properly afterward.
  3. The water tank and ice-full detecting plate should be cleaned with a mixture of neutral cleaner and water, sprayed onto surfaces, wiped with a clean cloth, rinsed, and dried.
