To ensure the health of ice-cream consumers and extend the service life of the Dispenser, the refrigerating cylinder must be cleaned and disinfected after every use.

1. Press the cleaning key to discharge all the slurry in the cylinder, and press it again and pause for a while.
2. Add lukewarm water mixed with an appropriate amount of liquid antiseptic into the cylinders to fill both cylinders with approximately the same amount of water.
3. Press the cleaning key again to stir for about 5 minutes before discharging the cleaning fluid.
4. Use lukewarm water instead to rinse the machine for 2-3 times. Pause for a while.
5. Power off, disassemble and wash the parts: Loosen the four screws on the outlet valve and disassemble the outlet valve unit. Take out the handle fastening pin, handle, valve rod, seal ring from the outlet valve in turns. Take out the stirrer from the refrigerating cylinder. Clean all the disassembled parts. Replace the damaged part with a new one. Re-assemble the parts in reversed order.

2. Cleaning of the dispenser body

What consumers need is a fine-looking, clean and sanitary device. Please keep the body clean. A warm towel can be used to wipe the machine body and remove stains. Never rinse directly with water to prevent the device from malfunctioning.

3. Cleaning of condenser

The condenser will be covered with dust after operating for a period of time, resulting in poor heat dissipation and refrigeration, so it must be cleaned every two months. It is best to ask a professional cleaning worker to clean it. Before cleaning, be sure to cut off the power and not to damage the condenser fins.

4. Adjustment of the belt

After operating for a period of time, the drive belt of the stirring system may be lengthened and loosened, which shall be adjusted in time, preferably by a professional technician. The dispenser must be cut off from power supply before being adjusted. If you still feel that the belt is too loose, you shall replace it with a belt of the same type.
