Disassembly and Cleaning (cont.)

4.Remove stationary half 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 R)

5.Slide the rotary half of the seal off the dasher shaft. Inspect both seal components carefully for nicks or cracks. Replace seal if defective.

NOTE: To prevent leakage the surfaces of the rotary seal and the stationary seal must be smooth with no chips or cracks.

NOTE: All units are shipped with a standard ceramic seal (Part # W0340201) unless otherwise specified. Certain products contain coconut oil which requires a different sealing material. For these products use the coconut oil seal (Part # W0340210). The stationary half of the standard seal has a white polished surface. The stationary half of the coconut oil seal has a glossy black surface.

6.Remove carb tube from bottom of hopper and remove o-rings. (See Figure S).

7.Remove drip tray and empty contents.

8.Take all components to the cleaning area.

9.Prepare 1 gallon solution of hot tap water and a good grade of dishwashing detergent.

10.Thoroughly wash all components in a warm, mild detergent solution including the inside of the freezing cylinder and the mix storage hopper. DO NOT WASH COMPONENTS IN A DISHWASHER.

11.Use a medium sized brush to clean the bottom of the valve body and the inside of the plunger bore with detergent solution taking care to remove only remaining lubricant. (Figure T)

12.The exterior of the freezer should be cleaned as needed with a cloth towel.

CAUTION: Coarse rags, abrasive cleaners and excessive force can ! damage and/or scratch the surfaces of the freezer.

NOTE: Allow all parts to dry completely before reassembly.

 

1. Reassemble drip tray and re-install on front of unit.

Figure T Clean Valve Body

 

2.Wet the inner rubber lip of the rotary half of the seal and the back end of

the dasher shaft with water. Slide rotary half of assembly onto the dasher shaft, RUBBER FIRST, with the smooth sealing surface facing the back of the dasher. (See Figure U). Be sure the rotary half is fully seated against the shoulder of the shaft.

3.Insert the stationary half of the seal into the ribbed rubber boot with the

polished surface facing out (forward). 4. Lightly lubricate the ribbed rubber boot of the stationary ceramic seal (taking care

not to get any lubricant on the polished surface) and insert it straight back into the recess at the back of the freezing cylinder, RUBBER FIRST. (See Figure V)

NOTE: The stationary half of the seal must be completely dry before reassembling. If the circular half of the seal is white, make sure that the grooved side is toward the rubber. If the circular half is black, be sure the glossy side is facing out.

5.Reassemble the dasher assembly, as shown in Figure W. Insert the larger front and smaller rear white plastic bearings into dasher, then slip in the stator rod. Attach scraper blades.

6.Carefully and slowly guide the dasher into the freezing cylinder, taking care

not to damage the seal assembly. Turn dasher shaft until it engages the square

drive coupling. Slide the dasher back into the cylinder so that the two smooth

stationary half seal

sealing surfaces meet. (See Figure X)

 

7. Inspect and lightly lubricate the large square o-ring

 

and refit it into the back of the valve block

 

assembly. Install the valve assembly on the front

 

studs and tighten the knobs until they are finger

 

tight. Do not use tools to tighten knobs.

 

NOTE: Failure to lightly lubricate the large o-ring can
