Rinsing
Step 1
Pour two gallons (7.6 liters) of cool, clean water into
the mix hopper. With the brushes provided, scrub
the mix hopper, mix inlet hole, and mix level sensing
probes.
Step 2
With a mix pail beneath the door spout, place the
control switch in the “WASH” position and raise the
draw arm. Drain all the rinse water from the freezing
cylinder. When the rinse water stops flowing from
the door spout, lower the draw arm and place the
control switch in the “OFF” position.
Repeat this procedure until the rinse water being
drawn from the freezing cylinder is clear.
Cleaning
Step 1
Prepare an approved 100 PPM cleaning solution
(examples: 2-1/2 gal. [9.5 liters] of Kay-5Ror 2
gal. [7.6 liters] of Stera-SheenR). USE WARM WA-
TER AND FOLLOW THE MANUFACTURER'S
SPECIFICATIONS.
Step 2
Pour the cleaning solution into the hopper and allow
it to flow into the freezing cylinder.
Step 3
While the solution is flowing into the freezing
cylinder, brush clean the mix hopper, mix inlet hole
and mix level sensing probes.
Step 4
Place the control switch in the “WASH” position.
This will cause the cleaning solution in the freezing
cylinder to agitate.
Step 5
Place an empty mix pail beneath the door spout and
raise the draw arm. Draw off all the cleaning
solution. When the solution stops flowing from the
door spout, lower the draw arm and place the control
switch in the “OFF” position.
Disassembly
Note: Failure to remove, brush clean and air dry
these items, will result in damage to the related
components.
Step 1
BE SURE THE CONTROL SWITCH IS PLACED IN
THE “OFF” POSITION.
Step 2
Remove the handscrews, freezer door, gasket, front
bearing, beater, scraper blades, and drive shaft from
the freezing cylinder. Take these items to t he sink
for cleaning.
Step 3
Remove the drip pan from the machine.
Note: If the drip pan is filled with an excessive
amount of mix, this indicates that the drive shaft seal
and o-ring should be replaced or was improperly
lubricated.
Step 4
Remove the front drip tray and splash shield.
Brush Cleaning
Step 1
Prepare a sink with an approved 100 PPM cleaning
solution (examples: Kay-5Ror Stera-SheenR).
USE WARM WATER AND FOLLOW THE
MANUFACTURER'S SPECIFICATIONS.
If an approved cleaner other than Kay-5Ror Stera-
SheenRis used, dilute according to label instruc-
tions. IMPORTANT: Follow label directions . Too
STRONG of a solution can cause parts damage,
while too MILD of a solution will not provide ade-
quate cleaning. Make sure all brushes provided with
the freezer are available for brush cleaning.
Step 2
Remove the seal and o-ring from the drive shaft.
Step 3
Remove the scraper blade clips from the scraper
blades.
