OPERATION
Sanitize the Machine
NOTICE: The United States Department of Agriculture and the
Food and Drug Administration requires that all
cleaning and sanitizing solutions used with food
processing equipment be certified for this use.
NOTICE: Always follow state and local codes for cleaning and
sanitizing.
Sanitizing must be done after the machine is cleaned and just
before the machine is filled with mix. Sanitizing the night before
is not effective. However, you should always clean the machine
and parts after using it.
1. Read the instructions for Stera-Sheen® Green Label Sanitizer
or equivalent product for creating a 100 ppm strength
solution.
2. Mix the sanitizer in quantities of no less than 2 gallons (7.6
liters) of approximately 90° to 110°F (32° to 43°C) water.
3. Check the strength of the sanitizing solution. Use a chlorine
test strip and a color chart to make sure the solution has 100
ppm.
4. Pour the solution into the bowl(s).
5. Using a suitable brush, wipe the solution onto all parts above
the level of the solution and on the underside of the cover.
6. Install the cover.
7. Position the Cold Drink/Granita switch to I (Cold Drink).
8. Operate the machine for approximately 5 minutes.
9. After 5 minutes, place a container under the spigot. Open the
spigot to drain the sanitizing solution. Do not discard the
solution.
10.Use a new test strip to test the solution. A reading of 100 ppm
or more is acceptable. If the reading is less than 100 ppm,
sanitize the machine again.
NOTICE: If the reading is less than 100 ppm after sanitizing the
second time, disassemble and wash the machine
again.
Mix and Recipe Guidelines
NOTICE: Amount of Sugar
The sugar level of the mix or recipe must be between
13-17 percent. Mixes with sugar levels outside of this
range will not freeze properly. If the sugar is less than
12 percent, the machine may over-freeze the mix. If
the sugar is greater than 18 percent, the machine will
have difficulty freezing the mix.
NOTICE: Custom Recipes
When using a custom recipe instead of a commercial
mix, Vollrath strongly recommends using a
refractometer to measure the sugar content.
NOTICE: Alcohol Ingredients
Alcohol is an antifreeze. Replace NO more than ¼ of
the water required in the recipe with alcohol.
• If using liquid or powder bases, specially prepared for granita,
follow the manufacturer's instructions carefully.
• If using natural products to prepare granita (for example
lemon juice, orange juice or coffee), dissolve 3.5 - 7 ounces of
sugar in each quart of product.
• If using freeze-dried bases to be diluted with milk or water,
prepare the product in a separate bowl, and only pour it into
the machine bowls after making sure it is homogeneous, and
the powder is well dissolved.
Add Mix
1. Remove the top cover from the bowl, press the lock button
and slide the cover toward the front of the bowl.
2. Fill the bowl with the desired product. Maximum liquid mix is:
• 6 liter bowls: 1.5 gallons (5.7 liters)
• 10 liter bowls: 2.5 gallons (9.4 liters)
Refrigerate
1. Set the power switch to the I position.
2. Set the Soft Drink/Granita switches as follows:
• Cold Drinks set to I position
• Granita set to II position
3. Set the light switch to the I position.
Serve
Monitor product for desired temperature or consistency. Product
is ready to serve when it reaches temperature or desired
consistency.
Tips
The length of time before a product is ready to serve is affected
by many variables, such as ambient temperature, initial mix
temperature, sugar content (Brix level), and the consistency
setting.
To shorten recovery time and increase productivity:
• Pre-chill the product to be used in the machine.
• Refill the bowl after the product level drops below the halfway
point of the evaporator cylinder.
NOTICE: Do not overfill the bowl. Fill only up to the max fill
line.

maintenance unless the machine is disconnected from its power
source.
The cover must be on the machine when the auger is in motion.
