Operating Procedures

Rinsing
1. Pour 2 gal. (7.6 L) of cool, clean water into the mix
hopper. With the brushes provided, scrub the mix
hopper, mix inlet hole, and mix-level sensing probes.
2. With a 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
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
®
).
Important! 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. Open the prime plug on the door.
4. While the solution is flowing into the freezing cylinder,
brush clean the mix hopper, mix inlet hole, and

mix-level sensing probes.
5. When the solution starts leaking from the prime port,
close the prime plug.
6. Place the control switch in the Wash position. This
will cause the cleaning solution in the freezing
cylinder to agitate.
7. Place an empty 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.
1. Make sure the control switch is placed in the OFF
position.
2. Remove the handscrews, freezer door, gasket, front
bearing, beater, scraper blades, and drive shaft from
the freezing cylinder. Take these items to the sink for
cleaning.
3. Remove the drip pan from the machine.
Note: If the drip pan is filled with an excessive
amount of mix, the drive shaft seal and O-ring should
be replaced or was improperly lubricated.
4. Remove the front drip tray and splash shield.
Brush Cleaning
1. Prepare a sink with an approved 100 PPM cleaning
solution (examples: Kay-5
®
or Stera-Sheen
®
).
Important! Use warm water and follow the

manufacturer's specifications.
If an approved cleaner other than Kay-5
®
or

Stera-Sheen
®
is used, dilute according to the

manufacturer’s instructions.
Important! Follow 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. Remove the seal from the drive shaft.
3. Remove the draw valve and prime plug from the
freezer door. Remove the two O-rings from the draw
valve and the O-ring from the prime plug.
Note: To remove O-rings, use a single-service
towel to grasp the O-ring. Apply pressure in an
upward direction until the O-ring pops out of its
groove. With the other hand, push the top of the

O-ring forward; it will roll out of the groove and can be
easily removed. If there is more than one

O-ring to be removed, always remove the rear O-ring
first. This will allow the O-ring to slide over the
forward O-rings without falling into the open grooves.
