Cleaning Following Complete Disassembly of Unit (cont.)

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 cylin- der, 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. Thoroughly wash and sanitize all components, lubricate the inside bore of valve body with a thin film of food grade sanitary lubricant. Reinstall the

O-Rings on the plunger assembly and lubricate the entire plunger. Reassemble the valve and replace the retainer pin. Inspect and lubricate the

large O-Ring and refit it into the rear of the valve assembly. Install the valve assembly on the front studs and tighten knobs until they are finger tight. Do not use tools to tighten knobs.

5.Disassemble the carburetor assembly and remove the O-Rings. Wash and sanitize all parts.

6.Reinstall and lubricate the O-Rings and slip on the outer tube if equipped. (See Figure BB.) Repeat reassembly on the other side.
