Disassembly and Cleaning (cont.)

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 stationary seal must be smooth with no chips or cracks.

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

standard seal has a white polished surface. The stationary half of the coconut oil seal Figure P Carb Tube has a glossy black surface.

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

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 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

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

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

1.Reassemble drip tray and install.

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 toward the back of the dasher. (see Figure R). 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).

recess at the back of the freezing cylinder, RUBBER FIRST. (Figure S)

 

 

 

 

 

 

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 T. Insert the larger front
