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: SteraSheen 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 the beater to run for 5 minutes.
During this time period check for leaks
around the head, plunger and drain
tube.
9. Place an empty container under
the dispensing head and drain the
sanitizing solution from the cylinder by
slowly pulling down on the dispense
handle. Open and close the handle
approximately 10 times during
draining to sanitize the port area of
the dispense head.
10. With most of the sanitizing solution
drained, turn the selector switch to the
“OFF” position and drain remaining
solution from the hopper and cylinder
and close the plunger.
2. Wash and sanitize your hands and
forearms.
3. The mix feed tube assembly should be
laying in the bottom of the hopper pan.
Do not install.
Important:
Never let the sanitizer remain in the
freezer for more than 15 minutes.

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.
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, ensure
that the mix feed regulator is
“OPEN” at all times. If not open,
the ow of mix will be restricted. If
lubricant blocks the inlet hole in the
tube it would also restrict the ow of
mix.
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.
Pin is in line with hole.
Look through top hole
in tube — you should

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
* Your Electro Freeze Distributor can
provide a scale (P/N HC158049) that is
graduated in overrun percentage.
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.
184592-0129
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,
