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 Stern-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/Granite 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, Travolta strongly recommends using a refractory 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
CAUTION
Do not operate the machine unless all panels are secured with screws.
Do not put objects or fingers in panel louvers or spigot outlet.
Do not remove bowls, augers, or panels for cleaning or routine maintenance unless the machine is disconnected from its power source.
The cover must be on the machine when the auger is in motion.

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/Granite switches as follows:
   • Cold Drinks set to I position
   • Granite 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-fill 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.

Store Product Overnight in the Machine
Prepared product can be stored overnight in the machine.

1. Leave the Main Power switch set to I (ON).
2. Position the Cold Drink/Granite switch to I (Cold Drink). This will keep refrigeration on and turn the augers, which will keep the product at a safe temperature for food storage, and preserve product quality and prevent it from freezing.
3. To return the product to Granite mode: One hour before serving time, position the Cold Drink/Granite switch to II (Granite Mode) to return the product to desired consistency.

Adjustments
Granite consistency adjustment
Proper Granite viscosity is factory preset. To change the consistency, use a standard screwdriver to turn the adjustment screw located on the each bowl as follows:

• Thicker product: Turn screw clockwise; the indicator moves toward Max.
• Thinner product: Turn screw counterclockwise; the indicator moves toward Min.

Cold Drink temperature adjustment
Note: Beverage temperature control is only available when the Cold Drink/Granite switch is set to the I (Cold Drink) position.
Proper beverage temperature is factory preset. To adjust, turn the temperature control knob for each bowl as follows:

• Decrease temperature: turn clockwise
• Increase temperature: turn counterclockwise

CLEAN THE MACHINE

NOTICE: Local and state health codes dictate the procedure required. Some health codes require a four-sink process (pre-wash, wash, rinse, sanitize, and air-dry), while other codes require a three-sink process (without the pre-wash step). The following procedure is a general guideline only. Consult your local and state health codes for procedures required in your location.
NOTICE: Hand wash only. Do not wash any components in the dishwasher.
