8 Start-up Instructions
8.1 Sanitizing
The sanitizing instructions explained in
this section are procedures to remove
bacteria and maintain a clean, sanitary
freezer. The shake freezer must be
disassembled, washed, and sanitized according to the instructions in this manual
before start-up to insure the best possible
cleanliness.
CAUTION
To prevent bacteria growth,
use only approved sanitizers
to sanitize the freezer.
Sanitizing must be done just
prior to starting the freezer.
Failure to do so could create
a health hazard.
Important:
Do not use unapproved sanitizer or
laundry bleach. These materials may
contain high concentrations of chlorine and will chemically attack freezer
components.
NOTE: It is your responsibility to be
aware of and conform to the requirements
for meeting federal, state and local laws
concerning the frequency of cleaning and
sanitizing the freezer.
1. Prepare 2 gallons (7.6 liters) of
sanitizing solution in a container. Sanitizing solution must be mixed according to
manufacturer’s instructions to yield 100
PPM strength chlorine solution. (example:
Stera-Sheen Green Label). Use warm water (100-110°F or 37-43°C) to wash, rinse,
and sanitize.
Important:
Do not insert any tools or objects into
the mix feed port or head dispensing
hole while the freezer is running.
4. Pour sanitizing solution into the
hopper pan. Using a clean brush, scrub
the hopper walls, the mix feed port from
the hopper to the cylinder, the inside of
the mix feed tube and adapter (see gure
8-1), and the inside of the hopper cover.
5. Insert mix oat on mix level sensor.
6. Allow sanitizer to ll the cylinder.
7. Connect the main power supply.
8. The syrup switch should be in
the “OFF” position. Place the selector
switch to the “CLEAN” position and allow

8.2 Priming
Priming the freezer removes all excess
air and sanitizer from the freezing cylinder
and sets the proper overrun for the rst
cylinder of product. Always have clean,
sanitized hands when handling mix feed
assemblies. Handle only the top 1”. Make
sure the mix feet tube assembly and the
inside of the hopper cover are cleaned
with sanitizer.
1. Wash and sanitize your hands
and forearms.
2. Place an empty container under
the dispense head. Install the mix feed
tube assembly in the closed position,
as shown in gure 8-2, into the mix feed
drain in the hopper. Pour a minimum of
2-1/2 gallons of mix into the hopper.
3. Hold the plunger open and
remove the mix feed tube to allow mix to
push out the sanitizer. When pure mix
ows from the dispense head close the
plunger.
4. When the mix stops bubbling
install the mix feed tube into the mix feed
hopper drain in the “open” position. Place
the selector switch to the “AUTO” position
and the syrup switch to the “ON” position.
Important:
Failure to completely remove sanitizer
or water from the freezing cylinder
before placing in “AUTO” will damage
the freezer.
5. Fill the hopper with mix and Install
the hopper cover.
6. During long idle periods, the
regulator should be closed — but
remember — when dispensing product,

10 Product Information
10.1 Overrun
As mix is frozen in the freezing cylinder,
air is incorporated into the mix to increase
its volume, as well as enhance the taste
and texture of the nished product. The
increase in volume is called overrun. Fifty
percent overrun means a volume increase
of 50%—10 gallons of liquid mix has
become 15 gallons of nished product.
Controlled overrun is important to
maintain consistency in product quality.
Too much overrun (air) results in a light,
uffy product lacking the cold, refreshing
appeal of a quality product. Too little
overrun results in a wet, heavy product.
To correctly measure the overrun, perform
the following steps:
a. Place an empty pint container on
the scale* and adjust your scale to zero.
b. Remove the container from the
scale and ll with liquid mix. Measure and
record the weight.
c. Remove the liquid mix and ll the
same container with frozen product. Be
sure there are no voids or air spaces in
the container.
d. Strike off the excess product so it
is even with the top of the container and
measure the weight.
e. Use the following formula to gure
overrun percentage:
“Weight of liquid mix minus weight of
frozen product/divided by the frozen
weight.” See example.
Example:
Weight of one pint of mix = 18 oz.
Weight of one = 12 oz.
pint frozen product
Difference = 6 oz.
6.0 oz. divided by 12 oz. = .5
.5 x 100 = 50% overrun
10.2 Rerun
If local health codes permit the use
of rerun make sure to follow these
procedures:
1. Store rerun mix in a clean,
sanitized container.
2. Store in a cooler with a
temperature below 40ºF (4.4ºC).
3. DO NOT prime the machine with
rerun. Always skim off and discard foam.
Then combine the rerun with fresh mix
in a ratio of 50/50 and add to the hopper
during operation.
4. Once a week run the mix as low
as possible and discard after closing. This
will break the rerun cycle and reduce the
possibility of high bacteria and coliform
counts.
* Your Electro Freeze Distributor can
provide a scale (P/N HC158049) that is
graduated in overrun percentage.
NOTE: Rerun product is unable to
accept the same amount of air as fresh
product. As a result, the quality will
be affected and product may appear
grainy and icy.
For further information contact your local
Electro Freeze distributor or the Service
Department of H. C. Duke & Son, LLC,
phone (309) 755-4553 or (800) 755-4545.
