Draining Product from the Freezing
Cylinder
1. Place the power switch in the OFF position as far
ahead of cleaning time as possible to allow frozen
product to soften for easier cleaning.
2. Remove the hopper cover and the air/mix feed tube
(if the machine is equipped with an air/mix feed tube).
Take these parts to the sink for cleaning.
3. If local health codes permit the use of rerun, place
a sanitized, NSF-approved stainless-steel rerun
container beneath the door spout. Place the power
switch in the WASH position and move the draw
handle to the right. When product stops flowing from
the door spout, move the draw handle to the left and
place the power switch in the OFF position. Put the
sanitized lid on the rerun container and place it in the
walk-in cooler.
Note: If local health codes do not permit the use of
rerun, the product must be discarded. Drain the
product into a pail and properly discard it.
Rinsing
1. Pour 2 gal. (7.6 L) of cool, clean water into the mix
hopper. With the brushes provided, scrub the mix
hopper, float switch, and mix inlet hole.
Figure 6-42
2. With a pail beneath the door spout, place the power
switch in the WASH position and move the draw
handle to the right. Drain all the rinse water from the
freezing cylinder. When the rinse water stops flowing
from the door spout, move the draw handle to the left
and place the power switch in the OFF position.
Repeat this procedure until the rinse water being
drawn from the freezing cylinder is clear.
Cleaning
1. Prepare an 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.
2. Pour the cleaning solution into the hopper and allow
it to flow into the freezing cylinder.
3. While the solution is flowing into the freezing cylinder,
brush-clean the mix hopper, float switch, and mix
inlet hole.
4. Place the power switch in the WASH position. This
will agitate the cleaning solution in the freezing
cylinder.
5. Place an empty pail beneath the door spout and
move the draw handle to the right. Draw off all the
cleaning solution. When the solution stops flowing
from the door spout, move the draw handle to the left
and place the power switch in the OFF position.
Disassembly
WARNING! Make sure the power switch is in
the OFF position. Failure to follow this instruction may
result in severe personal injury from hazardous moving
parts.
1. Remove the torque arm, handscrews, freezer door,
torque rotor, beater assembly, scraper blades, and
driveshaft from the freezing cylinder. Take these parts
to the sink for cleaning.
2. Remove the front drip tray and the splash shield.
Take these parts to the sink for cleaning.
3. Remove the rear drip pan from the front panel.
Note: If the drip pan is filled with an excessive amount of
mix, the driveshaft seal should be replaced or properly
lubricated.
ALWAYS FOLLOW LOCAL HEALTH CODES.
