CLEANING AND MAINTENANCE

There is no set period and procedures of the maintenance. It depends on the using and working condition, so each ice cream machine needs
A. Cleaning

1. Cleaning of hopper and cylinder
   1.1 Press “WASH” button and draw off all the residual mix in the hopper and cylinder, then press “WASH” button again to stop.
   1.2 Prepare 3 liters of solution using sanitizer in a bucket of cold water, pour the solution into the hopper.
   1.3 Press “WASH” button and let the machine run for 3 minutes, then draw off all the sterilizing solution, repeat the above steps with clean water two or three times to clean the machine thoroughly, press “WASH” button to stop the machine.
   1.4 Unplug the machine, remove and wash all the parts.
   ● Unscrew the four bolts on the dispenser door and remove the dispenser door.
   ● Disassemble the parts of the dispenser door in turn, pin, handle, piston, O-rings.
   ● Remove the auger from the cylinder, and then remove the gasket for the auger.
   ● Clean all the parts, and change new ones if it is necessary.
   ● Assemble all the parts according to reverse procedure of disassembling, use lubricate while assembling the piston, O-ring and gasket.
   1. Before installing the piston, O-ring for piston, beater and gasket for auger, you should lubricate Vaseline (lubricating Vaseline onto the groove of the gasket, do not onto the auger’s end ), using the Vaseline frequently can extend the service life of components.
2. Cleaning of the exterior of machine
   Keep the exterior of machine clean, use wet towel to clean it, and do not flush the machine with water directly.
3. Cleaning of condenser
   After be used over a period of time, the condenser maybe thick with dust, and this will effect heat dissipation and cause bad refrigeration, so it needs periodic cleaning (every half year).

Cleaning methods:
Step 1: Disconnected the main power switch.
Step 2: Remove the back panel and side panels.
Step 3: Clean dust with tools such as vacuum cleaner, high-pressure air and soft brush, be careful while cleaning to avoid damaging the fins of the condenser.
B. Maintenance Tip

• Be sure to drain the product, and thoroughly clean and sanitize your unit daily. Proper cleaning and preventative maintenance results in a creamier product consistency, increases your unit reliability and efficiency, and prevents costly repairs from occurring in the future.
• Do not run the machine while the machine is empty. This can severely damage the internal parts.
• Be familiar with all the operational modes of your machine and what they do. Understand the different features of each mode for safe and reliable operation.
• Use a recommended soft serve machine cleaner and sanitizer when cleaning your unit. Regular dish soap, chemicals, and detergents can degrade seals and leave unwanted residues in your machine.
• Do not run the machine with water in Auto Mode. The water will solidify into ice, expand, and severely damage the beater, freezing cylinder, bearing, and drive motor which can lead to unrepairable damage.
• Lubricate seals and o-rings with a food grade lubricant
• Do not pour water, product, or any fluid into the hopper while the beater are removed from the freezing cylinder. Doing this will cause the fluid to be discharged from the discharge tube located under the machine.
• Do not add any candies, jellies, or other particles into the hopper. Particles may clog the passageway leading into the freezing cylinder causing damage to the unit.
• Do not operate the machine while the stainless steel panels are removed from the unit. Loose garments and long hair can get caught in the moving parts resulting in serious injury.
