13.1 CLEANING PROCEDURE
Follow these steps for cleaning: (All water used must be potable water)
1. Firstly take off air tube.
2. Close the hopper cover, turn the machine to the “WASH” mode and wait 3 minutes.
3. Place an empty container under the dispense head and drain the remaining Soft-
Serve and liquid into a clean, sanitized bucket. Immediately place a tight sealing lid
onto the bucket and store refrigerated. (preferably below 5ºC)
4. Fill the hopper with cold water and allow the machine to run for 2-3 minutes before
draining the water into the bucket.
5. Fill the hopper with warm water. Allow the machine to run for approximately 5
minutes before draining the liquid into the bucket.
6. Repeat step 4 until the water runs clear.
7. Set the control dial to STOP mode and then switch off the power at the wall socket
and unplug the power cable.
8. Remove the screws of the Dispense Head.
9. Remove and disassemble the Dispense Head, Piston, Beater and O-rings. (Please
use the O-ring remove apparatus. (Figure 13))
10. Remove and disassemble hopper agitator.
11. Remove the liquid level sensor. Remove the retaining ring and float.
12. Wash and sanitize hopper, barrel and all the removable parts according to the
sanitizer manufacturer’s instructions and allow the parts to air-dry. Do not use any
chemicals other than the approved Sanitizer during the cleaning process.
13. Assemble all the parts, ensuring the O-rings and their groves are properly lubricated.
14. Start by lubricating the harmonica-shaped Beater Shaft seal and slip it onto the
beater shaft:
a. Place the beater into the barrel and turn it slowly until it locks into position.
b. Lubricate the smaller O-rings, slip them onto the piston and place the piston
into the dispense head.
