Sanitizing and Refilling
1. Reassemble carburetors by installing the two o-rings at the bottom of the carb tubes.
2. Place the carburetor assemblies in the bottom of each hopper.
3. Install the o-rings on each valve plunger and lay plunger assembly on a clean piece
of paper towel.
4. Prepare a minimum of 2.5 gallons (9.5 liters) of sanitizing solution (Kay-5
Sanitizer/Cleaner or equivalent) following the manufacturer’s instructions.
NOTE: Add 1 ounce of Kay-5 to 2.5 gallons (9.5 liters) of 120°F (50°C) water to achieve
a concentration of 100 parts per million.
5. Dip a medium sized brush into the sanitizing solution and sanitize the inside bore
of the dispensing valve. (Figure Y)
6. Place a small amount of lubricant onto a piece of clean paper toweling. Use a
clean piece of paper toweling to pick up the small end of the valve plunger
assembly. Apply a thin film of lubricant from the other piece of paper toweling.
(Figure Z)
7. Slide the valve plunger spring over the small end of the valve plunger and, using
another clean piece of paper toweling, pick up the valve plunger at the outlet end
and insert plunger and spring into the valve body. (Figure AA)
8. Push up on the valve plunger and insert the stainless steel handle. (Figure BB)
9. Holding the handle down slightly so that the hole in the handle and valve block are
aligned, insert the dispensing valve handle retaining pin. (Figure CC)
10. Repeat on other side.
11. Pour sanitizing solution into the mix storage hoppers and allow the solution to fill
freezing cylinder. Use a large brush to sanitize all hopper surfaces. (Figure DD)
12. Turn panel switch on each side to “CLEAN” and allow freezer to run for 5 minutes.
13. Open dispensing valves and drain solution. Allow the dasher to push remaining
sanitizer out of the freezing cylinders. Once the sanitizing solution is drained,
turn panel switches to “OFF”.
14. Place a small amount of sanitary lubricant onto another piece of clean paper
toweling. Use a clean piece of paper toweling to pick up the large end
of the carburetor from the bottom of the hopper taking care not to touch the
sanitized carburetor with your bare hand (Figure EE). Apply the
lubricant on the other piece of paper toweling to the two o-rings on the
bottom of the carburetor assembly (Figure EE).
15. Place the lubricated carburetor assembly on a clean piece of paper
toweling. Repeat with other carburetor assembly.
16. Prepare fresh product according to manufacturer’s instructions.
17. Hold open the dispensing valve and pour product (approx. 10 oz.) into the
hopper to allow this product to chase out any remaining sanitizer. Watch the
product flowing out of the dispensing valve and close the valve when the new
mix has purged the sanitizer remaining in the cylinder.
18. Use a clean piece of paper toweling to insert the sanitized carburetor
assemblies into the inlet hole in each hopper.
19. Fill mix storage hopper with fresh product. Cover hopper with hopper lid.
20. Turn one front panel switch to “ON”. Allow approximately 20 minutes for the freezer to reach proper consistency,
then turn the other front panel switch “ON” to freeze down other side.
