SETTING THE TIMER CLOCK*

1. With the main power switch off, turn the outer wheel on the timer

clockwise until the correct time (AM or PM) lines up with the arrow on

the clock face.

2. Turn on the main power switch to start the clock.

TIMER OPERATION*

Use the timer to start the unit automatically. This feature allows you to

pour the mix in ahead of time and have the slush ready to serve at the

programmed time (unattended operation). The timer determines when

the unit is in standby (night) mode or freeze mode. In standby mode the

mixture is kept cool, but does not freeze.

The unit comes from the factory set for manual (non-timer) operation.

When all of the timer tabs are ipped outward (see diagram, right), the

timer is disabled and the unit will freeze slush any time the refrigeration

switch is set to ON (|).

Setting Up the Timer

1. With the main power switch off, ip the timer tabs next to the time

marks on the timer to either the standby or freeze position. The unit

will operate in the mode selected during the corresponding time

period.

2. Check to make sure the clock is set to the current time, then turn ON

(|) the main power switch.

*Models CFB2 and CFB3 only.

CAUTION:

• Set the timer only with the main power switch in the

OFF () position .

• Turn the timer wheel only in the clockwise direction.

• Do not set the timer using any kind of tool.

IMPORTANT: The clock/timer is equipped with a backup circuit

and continues to keep time for 10 to 15 minutes after power is

interrupted. If the power cord is disconnected or the main power

switch is turned off for a longer period of time, the clock will need

to be reset when power is restored.

11. Open the control panel door (on the right side) and make sure the

main power switch is in the OFF () position.

12. Set the timer clock according to the

instructions below.

13. Connect the unit to a grounded,

3-prong, electrical outlet with the

appropriate amperage rating. The circuit

must be protected by a suitably rated circuit breaker. Do not use an

extension cord or any type of adapter.

14. Turn ON (|) the main power switch.

15. Clean and sanitize the unit before using it for the rst time as

instructed in the CLEANING section. Verify that the unit is operating

properly according to the operating instructions.

IMPORTANT: The unit

may not operate as

desired if the timer is not

set properly.

1. Dilute and mix the slush concentrate with water in a clean container. Follow the concentrate manufacturer’s

directions. THE MIXTURE OBTAINED MUST HAVE A MINIMUM SUGAR CONTENT OF 13°Bx and less than

22°Bx (11 to 20% sugar by weight). The capacity of each mixing bowl is 3 gallons (12 liters).

2. With the mixing switch in the OFF () position, remove the mixing bowl lid from the desired bowl and hang

it on the side. Pour in the mix up to, or below the MAX LEVEL indicator. The minimum level is just above the

plastic mixing auger.

3. Replace the mixing bowl lid.

4. Make sure the main power switch is ON (|). Push (|) on the mixing switch for the desired mixing bowl to turn

on the mixer.

5. Push (|) on the refrigeration switch for the desired mixing bowl to begin freezing. NOTE: On units equipped

with a timer, when the refrigeration switch is in position (|), the unit will freeze the slush mixture provided

the timer is set to freeze for the current time (see Setting the Timer). Standby mode, position (||) on the

refrigeration switch, may be used to put the unit in standby mode manually. This mode saves energy, keeping

the mixture cool without freezing.

6. Once the mixture is frozen (40 to 90 minutes), pull out on the top of the dispenser lever or push the bottom of the lever to dispense.

OPERATING INSTRUCTIONS

WARNING:

• Keep body parts and other items clear of the inside of the mixing bowl when the main power switch is

ON (|). Keep the mixing switch in the OFF () position whenever the mixing bowl lid is removed.

• To prevent damage to the unit and for good results, use only slush mixtures with the required sugar

content (see below). Do not use the machine to freeze water without slush concentrate added. Never

pour hot liquids (above 77°F/25°C) into the mixing bowl. This unit is not for use with milk/dairy based

products.

• Do not ll the mixing bowl higher than the MAX LEVEL indicator.

Adjusting Slush Thickness

Use the adjustment screws

at the back of each mixing

bowl to adjust slush thickness.

The recommended (factory

default) setting is 2. Insert a

at blade screwdriver into the

adjustment hole as shown and

turn to adjust. The indicator on

the back will move to indicate

the thickness level. The higher

the number the thicker the

higher levels, (around 4) the

lid should be fastened to prevent

it from coming off during operation.

OPERATING INSTRUCTIONS (CONT.)

Periodic maintenance

Have the unit checked periodically (at least once a year) by a qualied technician to ensure proper operation.

WARNING:

gloves.

• Never spray water on the unit to clean it.

• Do not use cleaning liquids, compounds or powders containing chlorine (bleach), solvents, scouring

powder, ammable materials or corrosives. These products promote corrosion and will damage the

surfaces. USE OF THESE PRODUCTS WILL VOID THE WARRANTY.

• DO NOT immerse the unit or parts in water or any other liquid, unless specically instructed to do so.

Do not wash any of the components in a dishwasher. Hand or air dry the parts only.

CLEANING

Daily Cleaning

It is recommended to clean and sanitize all of the bowl assemblies at least once a day according to the following steps. These

operations may need to be performed more frequently based on the mix used. Contact the concentrate supplier for more details. If

the machine is not used continuously throughout the day, wipe the tap areas with a clean cloth and sanitizing uid. If the dispenser

has not been used for a long period of time, clean the unit before returning it to use.

1. For cleaning, prepare a mild solution of detergent and warm water.

Empty the Drip Trays

The drip trays should be emptied and cleaned

every day and drained every time the red full

indicator pops up. They must also be removed

before emptying the bowl.

2. Lift each drip tray up and out.

3. Wash the trays and grills with the detergent

solution. Hand dry all of the components,

then reinstall the grills. Set the trays aside

and reinstall at the end of the daily cleaning

process.

TROUBLESHOOTING

Tap Leaks

1. Make sure that the (red) tap gasket is properly

lubricated and is not worn out.

2. Make sure that the tap handle assembly is properly

seated.

Slush Does Not Come Out of Tap

This problem is usually caused by slush that is too thick

or ice chunks forming in the bowl.

1. Make sure the slush mixture is properly diluted.

Proper sugar content is 11 - 20%.

2. Make sure the slush thickness setting on the back of

unit is not set too high.

Leak at Back of Mixing Bowl

1. Make sure that the mixing bowl is properly seated.

2. Make sure that the mixing bowl seal is properly

lubricated and is not worn out.

Auger Does Not Turn or is Noisy

1. Make sure the mixing switch is turned on.

Proper sugar content is 11 - 20%. An improperly

diluted mixture can cause ice chunks that can

interfere with proper auger operation.

3. Make sure the auger seal is properly installed and

lubricated.

High Pressure Light On (front panel)

CFB2 and CFB3 only. Turn off the main power switch

and check the following:

1. Make sure that there is sufcient ventilation. The

unit will not function properly if there is not sufcient

air space around the sides and back of the unit.

2. Make sure that the lter is clean and that the
