secondary regulator inside the unit is properly set to 28-32 PSIG (206.8 to 220.8 KPa), the
chamber pressure will be “set” automatically.

F.

After the machine is installed and each chamber is properly filled, press the “DEF” button on the
control panel to allow the machine to automatically “baseline”.  Baselining indicates to the
machine that the chamber contains liquid.  As a result, the machine sensors determine how
much to freeze the product.

G. The display will flash “DEFROSTING” until baselining is complete.  The machine will 

automatically start running if the machine was running when the defrost cycle was started.  If the
machine was not running before the defrost cycle started, the “RUN” button must be pressed.
Note that there may be a delay of up to two (2) minutes before the machine turns on after the
“RUN” button is pushed.  

This delay is normal. Do not press the 

“RUN” 

button again or press

any other buttons until the machine starts.

10.2 DRINK TOO HARD AND COLD

A. If the drink is too hard and cold or the chamber is not full, adjust the “level control” to a higher

level setting.  Use the recommended settings that follow to properly adjust the liquid level 
control settings.

B. It will be necessary to drain off several drinks to allow the chamber to fill and rebalance.  It is

also then necessary to defrost the chamber and allow the product to refreeze.  If the drink is still
too hard, repeat the process taking the level control setting to the next higher value.

10.3 DRINK TOO LIQUID

A. If the drink is cold, but is still a liquid, adjust the level control to a lower level setting.  Use the 

recommended settings that follow to properly adjust the level control.

B. It will be necessary to drain off several drinks to allow the chamber to fill and rebalance.  It is

then necessary to defrost the chamber and allow the product to refreeze.  If the drink is still too
liquid, repeat the process taking the level control to the next lower setting.

C. If the product is still too liquid, it may be necessary to adjust the THAW-FREEZE beater settings.

Refer to Section 11 (Changing Factory Thaw and Freeze Settings).

D. Drink temperature should be between 24°F and 28°F (-4.4°C to -2.2°C).

NOTE

If "Wet" or "Dry" drinks are common to both chambers, adjust "Regulated CO

2

" up to lighten

drink or down to make drink wetter before adjusting level controls!

10.4 CHANGING THE DEFAULT LEVEL CONTROL SETTING

A. The level control setting is preset at the factory at a value of 3.
B. If the drink is not frozen enough, or if the drink is too hard and too cold and dispenses slowly,

after the machine has been running for 10 to 15 minutes, it may be necessary to adjust the level
control settings.

C. To change the machine’s level control settings, access the level two 

service menu

.

1.

Access the service level by pressing the “FWD” button on the control panel until the 
“SERVICE MENU” displays.  Press the unmarked button on the right side of the panel.
“Machine Settings” displays.
