Sanitizing and Refilling (cont.)
11. Watch the product flowing out of the dispensing valve and close the
valve when the sanitizer remaining in the cylinder has been purged
by the new mix.
12. Use a clean piece of paper toweling to insert the sanitized carburetor
assembly into the inlet hole in the hopper (figure V).
13. Fill mix storage hopper with fresh product.
14. Turn front panel switch to “ON”. Allow approximately 20 to 30 minutes
for the freezer to reach proper consistency.
Cleaning Following Complete Disassembly of Unit
1. Remove knobs and carefully remove the front dispensing
valve assembly.
2. Disassemble the dispensing valve assembly by removing the
retaining pin, pushing up on the plunger assembly and pulling
out the handle. This will allow the plunger assembly, complete
with O-Rings, to be removed as a unit. Remove the spring.
Remove the O-Rings from the plunger assembly and back
of the dispensing valve body. (See Figure W.)
Note: The best way to remove an O-Ring is to first wipe off all of the lubri-
cant using a clean paper towel. Pinch the O-Ring upward with a dry towel
between your index finger and thumb. When a loop is formed in the O-Ring,
roll it out of the groove with your other thumb. Always remove the O-Ring far-
thest from the end of the plunger first. (See Figure X).
Note: Carefully inspect the O-Rings and replace if necessary.
3. Remove the dasher assembly taking care to avoid damaging the rear
seal assembly at the back of the freezing cylinder.
4. Remove stationary portion of the shaft seal assembly from the back end
of the freezer cylinder. This is accomplished by reaching into the cylinder
and pulling seal out with your index finger. (See Figure Y)
5.Slide the rotary seal off the the auger shaft. Inspect both seal compo-
nents carefully for nicks or cracks.
Replace seal if defective.
Note: To prevent leakage, both surfaces of the seal must be smooth with no
chips or cracks.
Wash all components in a detergent solution, sanitize and allow to air dry.
