Hopper Cleaning
Note: Failure to follow these steps will result in milk-stone build-up.
Step 1
Prepare an approved 100 PPM cleaning solution (examples: 2-1/2 gal. [9.5 liters] of
Kay-5® or 2 gal. [7.6 liters] of Stera-Sheen®). USE WARM WATER AND FOLLOW
THE MANUFACTURER'S SPECIFICATIONS.
Step 2
With the prime plug pushed down, pour the cleaning solution into the hopper and
allow it to flow into the freezing cylinder.
Step 3
Using the white hopper brush, clean the mix hopper and the mix level sensing probes.
Using the double ended brush, clean the mix inlet hole.
Note: Do not brush clean the mix inlet hole while the machine is in the WASH mode.
Step 4
Touch the WASH symbol. This will cause the cleaning solution in the freezing cylinder
to come in contact with all areas of the freezing cylinder. Wait atleast 5 minutes before
proceeding with these instructions.
Step 5
Place an empty pail beneath the door spouts and raise the prime plug.
Step 6
When a steady stream of cleaning solution is flowing from the prime plug opening in
the bottom of the freezer door, open the draw valve. Draw off all the solution.
Step 7
Once the cleaning solution stops flowing from the door spout, close the draw valve
and push the prime plug down. Touch the WASH symbol, cancelling the WASH mode.
Repeat these steps for the other side of the machine.
Disassembly
Step 1
Place the power switch in the OFF position.
Step 2
Remove the handscrews, freezer door, beaters and scraper blades, and drive shafts
with drive shaft seals from the freezing cylinders.
Step 3
Remove the beater shoes and scraper blades from the beater assemblies. Remove
the scraper blade clips from the scraper blades.
Step 4
Remove the drive shaft seal from each drive shaft.
Step 5
From each pump cylinder, remove the retaining pin, mix inlet adaptor, valve cap,
pump gasket, and the piston. Remove the o-ring from the piston and valve cap.
