6. Raise the prime plug. Place an empty pail under the
door spout. When cleaning solution begins to exit the
relief port opening in the freezer door, lower the
prime plug. Press the OFF key. Open the draw valve
and relieve all pressure from the freezing cylinder.
Remove the hopper cover. Remove the mix feed tube
and take it to the sink for further cleaning. Close the
prime plug.
7. Prepare a pail of approved 100 PPM cleaning
solution (examples: 2-1/2 gal. [9.5 L] of Kay-5
®
or 2
gal. [7.6 L] of Stera-Sheen
®
). Use warm water and
follow the manufacturer’s specifications.
8. Slowly pour the cleaning solution into the mix hopper
until the hopper becomes 1/4 full of cleaning solution.
9. With the brushes provided, brush-clean the mix
hopper, mix inlet hole, mix level float switch, and
product fitting.
Important! Use caution when cleaning the float
switch. Failure to do so will cause damage to the
component.
10. Clean and install the hopper cover. Lock the cover
into place. Attach the vinyl tube to the pressure relief
valve on the hopper cover. Position the open end of
the vinyl tube into the rear drip pan.
11. Press the BEATER key to agitate the solution in the
freezing cylinder.
12. With a pail beneath the door spout, open the draw
valve and drain all the solution from the mix hopper
and the freezing cylinder. Press the OFF key and
close the draw valve.
13. Disconnect the syrup connector.
14. Repeat step 2 through step 13 for the remaining
freezing cylinder(s).
Disassembly
1. Make sure the control switch is in the OFF position.
Open the draw valves to make sure all pressure has
been relieved.
2. Raise the prime plug. Leave the bleed port open
when removing the freezer door to make sure all
pressure is relieved from the freezing cylinder.
3. Remove the following parts from the freezer, and
take them to the sink for brush-cleaning: handscrews,
freezer doors, baffle assemblies, beater assemblies,
scraper blades, drive shafts, hopper covers, front drip
tray, and splash shield.
Brush Cleaning
1. Prepare a sink with an approved cleaning solution.
(examples: Kay-5
®
or Stera-Sheen
®
). Use warm
water and follow the manufacturer’s specifications.
Important! Follow the label directions. Too strong of
a solution can cause parts damage, while too mild of
a solution will not provide adequate cleaning. Make
sure all brushes provided with the freezer are
available for brush cleaning.
2. Return to the freezer with a small amount of cleaning
solution. With a single-service towel, wipe clean the
bearing surface. Brush-clean the rear shell bearings
at the back of the freezing cylinders with the black
bristle brush.
