3. Open dispensing valve and drain solution. Allow the auger to push remaining sanitizer out of the freezing cylinder. 4. Place a small amount of sanitary lubricant onto another piece of clean paper toweling (see figure R).

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 hands. 6. Apply the lubricant on the other piece of paper toweling to the two “O” Rings on the bottom of the carburetor assembly (see figure S). 7. Place the lubricated carburetor assembly on a clean piece of paper toweling. Figure R Lubricate Carb Tube 8. Use either fresh product or mix new product according to manufacturer’s instructions. 9. Fill mix storage hopper with product. 10.Open dispensing valve. Pour product into the hopper and allow this product to chase out any remaining sanitizer. 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 (see figure T). 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. Repeat procedure for other side. 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 T.) NOTE: The best way to remove an O-Ring is to first wipe off all of the lubricant 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 farthest from the end of the plunger first. (See Figure U). 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 V). 5. Slide the rotary seal off the the auger shaft. Inspect both seal components 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.

IMPORTANT: After disassembly, thoroughly scour each part of the freezer in a warm mild detergent solution including the inside of the freezing cylinder and the mix storage hopper. Rinse each part with clean water. Prepare a minimum of 3 1/2 gallons (13 liters) of sanitizing solution (Divorsol CX or equivalent) following the manufacturer's instructions. NOTE: Add 3 ounces (85.4 mg) of Divorsol CX to 3 1/2 gallons (13 liters) of 120°F (50°C) water to achieve a concentrations of 200 parts per million. Dip or wipe each part in sanitizing solution and allow them to dry on clean paper toweling. Reassembly 1. Wet the inner rubber lip of the rotary portion of the seal and the back end of the auger shaft with water. Slide rotary portion of assembly onto the auger shaft, RUBBER FIRST, with the smooth sealing surface toward the back of the auger. (see figure W) 2. Insert the stationary portion of the seal into the grooved rubber boot with the polished surface facing out (forward). Lubricate the grooved exterior portion of the boot and insert it straight back into recess at the back of the freezing cylinder, RUBBER FIRST. (see Figures X & Y) NOTE: If the circular portion of the seal is white, make sure that the groove is toward the rubber (back of freezer). 3. Reassemble the dasher assembly, as shown in Figure Z. Insert the larger front and smaller rear white plastic bearings into dasher, then slip in the stator rod. Carefully and slowly guide the auger into the freezing cylinder taking care not to damage the seal assembly. Turn auger shaft until it engages the square drive coupling. 4. Reassemble the dispensing valve assembly as shown on Figure AA. Thoroug...
