Thesefilmswillaccumulateslowlyonsurfacesbecauseof
ineffective cleaning, use of hard water, or both. Milkstone
is usually a porous deposit, which will harbor microbial
contaminants and eventually defy sanitizing efforts.
CLEANING – This involves draining mix from the
freezing cylinder and rinsing the machine with
water.Next,acleanerisrunthroughthemachine.
Then,themachineisdisassembledandremovable
parts are taken to the sink for cleaning.
Once milkstone has formed, it is very difficult to remove. 2.
Without using the correct product and procedure, it is
nearly impossible to remove a thick layer of milkstone.
(NOTE: general-purpose cleaners DO NOT remove
milkstone.) This can lead to high bacteria counts and a
food safety dilemma.
MILKSTONE REMOVAL – Since almost all
cleaners do not have the ability to remove
milkstone, the use of a delimer becomes
necessary. Although this procedure may not be
needed on a daily basis, it will usually follow the
cleaning procedure. It requires letting a delimer
solution soak in the machine for an extended
period of time. Individual parts are also soaked in
a deliming solution for an extended period of time
(more about delimers in Additional Information).

THE USE OF DELIMERS
An UNCLEAN surface will harbor bacteria that can
defy sanitizing efforts.
A delimer is a strong acid that has the ability to dissolve
milkstone. This type of chemical may become necessary
once high levels of milkstone have developed. While
these products are very effective for removing HIGH
levels of milkstone, they are not ideal for two reasons:
Bacteria can develop and resist sanitizing efforts within a
layer of soil material (milkstone). Thorough cleaning pro-
cedures that involve milkstone removal are critical for
operators of frozen dessert machines.

F112 must have a minimum of 6” (15.2 cm) of ventilation
on the right and left sides of the unit for free flow of air. The
E112 must have 3” (7.6 cm) of ventilation. Make sure the
freezer is not pulling over 100° F (37° C) air from other
equipment in the area.
GENERAL PURPOSE CLEANERS
General purpose cleaners do not have the ability to re-
move milkstone. Milkstone will become a problem if not
remedied with additional products and procedures.
THE USE OF CHLORINE TEST STRIPS
Thecondenserandcondenserfilterrequireperiodicclean-
ing. To clean, refer to the following procedures.
“Test strips” are used to determine concentrations of
active chlorine in sanitizing solutions. To use the strips,
tear off a small portion and submerge it into the sanitizing
solution. Then, compare the color change to the color key
on the side of the test strip dispenser to determine the
approximate chlorine concentration.

The ideal concentration of chlorine needs to be 100 ppm
(as stated by the FDA).
NOTE
Follow the directions on the container for proper con-
centration.
There are two main factors that contribute to falling chlo-
rine concentrations in a sanitizing solution.

TROUBLESHOOTING
4.1 LIGHT INDICATORS
The freezer has two lights that will alert the user if a problem occurs: an ADD MIX light and a Diagnostic Light.
The ADD MIX light will flash to alert the operator to a low mix condition. It does so by monitoring the mix level in the
hopper. When the ADD MIX light is flashing, refill hopper immediately.
The Diagnostic Light will flash if an error occurs. Refer to the chart below for details.
