BEFORE FIRST USE

NOTICE: Do not lay the machine on its side or back.
NOTICE: Do not lift the machine by the tank, auger, or handles. Only

lift by grasping the bottom of the machine.

NOTICE: The machine must sit in the upright position for 24 hours

before turning it on. This will allow the oil in the
compressor to settle into place following shipping.

1. Remove the machine from the packaging, which you should keep in
case it is needed in the future.

2. Check that the machine has not been damaged during transport. If it
has, make a report to the carrier immediately.

3. Position the machine on a countertop capable of supporting the
weight, even at full load.

FEATURES AND CONTROLS

The machine is equipped with a power switch and a light switch. In
addition, each bowl is individually operated by a Cold Drink/Granita
switch. It is possible to dispense both cold drinks and Granita from one
machine.

When a bowl is in Cold Drink mode the beverage temperature is
controlled by the corresponding temperature control knob.

When a bowl is in Granita mode the mix consistency is controlled by
the corresponding adjustment screw. See “Adjustments” on page 4.

Before use, the machine must be disassembled, cleaned and sanitized.

1. Disassemble the machine. See page 5

2. Clean and sanitize the components. See page 4.

3. Re-assemble and lubricate the components. See page 6.

4. Sanitize the machine. See page 3.

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: Refer to local sanitary regulations for applicable codes and

recommended sanitizing products and procedures. The
frequency of sanitizing must comply with local health
regulations.

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
warm, approximately 90° to 110°F (32° to 43°C) water.

3. Check the strength of the sanitizing solution. Use a chlorine test strip
and 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 about five minutes.

9. After five 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 13­17%. Mixes with sugar levels outside of this range will not
freeze properly. Less than 12%, the machine may over­freeze the mix. Greater than 18%, 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 anti-freeze. 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 that it is homogeneous and that the powder
is well dissolved.

Add Mix

NOTICE: Do not operate the machine unless all panels are secured

with screws.

NOTICE: Do not put objects or fingers in panel louvers or spigot

outlet.

NOTICE: Do not remove bowls, augers, or panels for cleaning or

routine maintenance unless the machine is disconnected
from its power source.

NOTICE: 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. If there is a safety lock for the
cover, turn the key counterclockwise to unlock.

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 to 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/Granita 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 Granita mode: One hour before serving
time, position the Cold Drink/Granita switch to II (Granita Mode) to
return the product to desired consistency.

Frozen Beverage Granita Machines Operator’s Manual 3

OPERATION (CONTINUED)

CLEAN THE MACHINE

Adjustments

Granita consistency adjustment

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 counter-clockwise; the indicator moves
toward Min.

Cold Drink temperature adjustment

Note: Beverage temperature control is only available when the Cold
Drink/Granita switch is set to the I (Cold Drink) position.

To adjust, turn the temperature control knob for each bowl as follows:

• Decrease temperature: turn clockwise

• Increase temperature: turn counter-clockwise

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.

NOTICE: Do not use excessive amounts of water around the

electrical components. This could cause electric shocks or
damage to the machine.

NOTICE: Do not use abrasive materials, scratching cleansers or

scouring pads. Use only products designed for use with
plastic.
