The washing and sanitizing instructions
explained in this manual are procedures
to remove bacteria and maintain a clean,
sanitary freezer. The slush/cocktail freezer
must be disassembled and cleaned
according to the instructions in this
manual before assembly and sanitizing
(start-up) to ensure the best possible
cleanliness.
CAUTION
To prevent bacteria growth,
use only approved sanitizers to
sanitize the machine. Sanitizing
must be done just prior to
starting the machine. Failure
to do so could create a health
hazard.
Important:
Do not use unapproved sanitizers
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 the requirements for meeting
Federal, State and Local laws concerning
the frequency of cleaning and sanitizing
the freezer.
1. Wash and sanitize your hands and
forearms.
2. Prepare 4 gallons (15.2 liters) of
sanitizing solution (example: SteraSheen Green Label) in a container.
Sanitizing solution must be mixed
according to manufacturer’s
instructions to yield 100 PPM strength
chlorine solution. Use warm water
(100° to 110°F or 38° to 43°C) to
wash, rinse, and sanitize.

3. Pour sanitizing solution into the hopper
pan. Using a clean brush, wash down
the hopper walls, hopper cover and
the mix feed port from the hopper to
the cylinder, as shown in gure 8-1.
4. Remove air bleed plug and allow
sanitizer to ow into cylinder. Replace
the plug when sanitizer reaches
bottom of air plug opening.
Important:
Do not use the “FREEZE” position with
sanitizer in the cylinder. The freezer
will be damaged.
5. When the cylinder has lled with
sanitizing solution, reconnect the main
power supply to the freezer. Turn
the selector switch to the “CLEAN”
position and allow the beater to run
for 5 minutes.
6. At this time check for leaks around the
head, piston and drain tube.
Important:
DO NOT hang containers from the
dispensing spout — doing so will
damage the head.
7. Place an empty container under
the dispensing head, and drain the
solution by opening the piston to allow
the cylinder and hopper to empty.
8. When the sanitizing solution has
drained from the freezer, turn the
selector switch to the “OFF” position.
Important:
DO NOT use the freezer for purposes
other than freezing a “slush” product
or cocktail mix. DO NOT attempt to
freeze plain water. This will result in
damage to the freezer.
1. Use a container of sufcient capacity
and with gallon measurement
markings to accurately mix in
quantities required by the product
manufacturer’s instructions.
2. Prepare at least 5 gallons (18.9L) of
mix. Follow the directions exactly as
shown on product label.
EXAMPLE: If using a powdered
neutral base, add contents of
package, 5 lbs. (2.3 kg) of sugar,
8.3 Priming
Priming the freezer removes excess air from the freezing cylinder and sets the proper
consistency for the rst cylinder of product.
and just enough cold water to equal
5 gallons (18.9 L) of mix. Never add
more water than instructions call for.
NOTE: The product should
register between 11-13% Brix on a
refractometer or a hydrometer. Never
go below 11. (See Section 10.3)
3. You may precool the slush mix
and thereby gain added capacity in
your freezer, if desired. Cool at 36°F
(2°C) — DO NOT FREEZE.
4. Always thoroughly stir mix before
lling machine. Ingredients can
separate over time and change Brix
reading.
1. While holding the piston open, pour
the mix directly into the hopper,
allowing the mix to force out any
remaining sanitizer (approximately 8
ounces or 250 ml).
2. When pure mix appears (all sanitizer
has been expelled), close the piston.
Important:
Failure to completely remove sanitizer
or water from the freezing cylinder
before placing in “FREEZE” will
damage the freezer.
3. Remove the air bleed plug and allow
cylinder to ll with mix. Replace air
plug when mix reaches bottom of air
plug opening.
4. Finish lling the hopper with mix. The
freezer will hold 8.5 gallons—3.5
gallons in the freezer cylinder
and 5 gallons in the hopper. (32.3
Liters—13.2 L in cylinder and 18.9 L
in reservoir.)
NOTE: Do not allow the level of mix in
the hopper to fall below 1/3 full.
5. Turn the selector switch to the
“FREEZE” position.
6. Place the hopper cover over the
hopper.
7. When the mix has been frozen to the
proper consistency, the compressor
will automatically shut off. It will restart
whenever the product consistency
changes. The beater will run
continuously.
8. See Section 11, Slush Product
Information, for determining
consistency and making adjustments.
9. If your slush mix is above 70°F
(21°C), it will take approximately 30
minutes to freeze down to the proper
consistency.
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. If the mix is nonperishable (sugar
base), place the selector switch in the
“OFF” position at the end of the day.
2. To restart the freezer on the following
day, place the selector switch in the
“FREEZE” position. The mix in the
cylinder will remain partially frozen
overnight and this will reduce the
freezing time to 5 – 10 minutes.
9.1 Draining Product
To remove semi-frozen product from the
cylinder, perform the following steps:
1. Place the selector switch in the
“CLEAN” position.
3. If the mix is perishable (fruit base),
leave the selector switch in the
“FREEZE” position or drain the
product from the freezer into a
sanitized container. Cover and place
container in refrigerated storage.
NOTE: Follow state and local health
codes concerning reuse of product.
2. Place a clean, sanitized container

4. Look into the access hole and you will
see an arm extending from the drive
motor (see gure 10-1.) The arm is
held in place by springs on both the
top and bottom. At the end of this
arm is a nylon (product) adjusting
stud. This stud is the only operating
adjustment on the freezer.
5. If the product is too thin, turn the
adjusting screw counterclockwise
(up) ½ turn. If the product is too thick,
turn the adjusting screw clockwise
(down) ½ turn. Close cover and
reconnect power. Turn selector
switch to “FREEZE” and wait until the
compressor has cycled off.
6. Recheck the product consistency
in 30 minutes. Repeat steps and
recheck until proper consistency is
obtained. Close cover.

A refractometer measures soluble sugar
content of mix, expressed in percentage
weight. This is normally referred to as a
“Brix Reading.” The typical refractometer
uses a scale from 0% to 32%.
Adjust the refractometer according to
the manufacturer’s instructions.
NOTE: A refractometer is a delicate
instrument and must be handled
with care. Never immerse the entire
refractometer in a cold drink. Cooling
the refractometer will cause it to give
inaccurate readings. A refractometer
cannot be used to read dietetic syrups.
1. Open the hinged side of the
refractometer and place a few drops of
mix on the slide.
Close the slide and look through the eye
piece, holding the refractometer toward
the light. A line will appear across a
graduated scale which indicates the Brix
level.
Acceptable Brix level is 11-13 on a
refractometer.
NOTE: Never go below 11 on the Brix
Reading.
Some experimentation may be necessary
before correct Brix and serving
temperature will be found. Generally,
the higher the Brix reading the lower
the serving temperature. Conversely,
the lower the Brix reading, the higher
the required serving temperature. If the
complaint concerns product appearance,
(ie. too runny or too stiff) always rst
take a Brix reading of the mix because
variation in sugar content will have a
direct bearing on actual freezing point.
Electro Freeze recommends the following schedule to help maintain your equipment
in like-new operating condition, as well as to help protect your investment. Take the
