4. Remove the flare lines, suction lines, retaining pins,

and mix inlet fittings from the pump cylinders.
Remove the liquid valve bodies from the pump
cylinders. Remove the pistons from the pump
cylinders. Remove all O-rings and check bands.

5. Use a small amount of cleaning solution and the

black bristle brush to brush-clean the rear shell
bearings at the back of the freezing cylinders.

Figure 6-65

Important!

Cleaning the tubes requires special attention

because bacteria and milkstone can build up here.

6. Use the long, flexible brush and cleaning solution to

clean the mix inlet tubes in the mix cabinet.
Thoroughly clean the tubes all the way up to the
freezing cylinder.

7. Remove the rear drip pan from the side panel and

take it to the sink for cleaning.

Note:

If the rear drip pan is filled with an excessive

amount of mix, refer to the Troubleshooting Guide.

8. Thoroughly brush-clean all disassembled parts in the

cleaning solution. Make sure all lubricant and mix film
is removed. Take particular care to brush-clean the
draw valve cores in the freezer door.

9. Place the parts on a clean, dry surface to air-dry

overnight.

10. Wipe clean all exterior surfaces of the freezer and the

mix cabinet.
