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.
