Service Manual - Frozen Beverage Dispenser

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 frozen beverage 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 flipped outward (see diagram, right), 

the timer is disabled and the unit will freeze the mixture any time the 
refrigeration switch is set to ON (

|

).

Setting Up the Timer

1. 

With the main power switch off, flip 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

 (O) position.

• 

Turn the timer wheel only in the clockwise direction.

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.
