7.3 Regulated CO
2
Injection Pressure
The CO
2
injection pressure is set by adjusting the CO
2
regulators on the solution module, located behind the
access panel below the keypad in the front of the machine. The CO
2
regulators should be set at 58 to 62 psig
(400 to 427 kPag). The dispenser then automatically sets the barrel pressure between 25 and 30 psig (172 and
207 kPag).
7.4 Thaw and Freeze Settings
The thaw and freeze settings signal the refrigeration system when to start and stop freezing. The liquid in the
barrel freezes until it reaches the desired frozen consistency; then, the refrigeration system shuts off and the
barrel begins to thaw. The liquid continues to thaw until it reaches a consistency specified by the thaw value.
The thaw value is the point at which the refrigeration system turns back on and refreezes the product. This as-
sures the product is maintained in a good, acceptable, frozen drink range.
Prior to changing any thaw or freeze settings, make sure the brix and water flow rate are correct and the liquid
level control settings are properly set. Also assure the barrels stay filled to the proper levels with the prop
-
er amount of CO
2
. The optimum frozen drink temperature is 24°F to 28°F (-4.4°C to -2.2°C) and should be
checked prior to making any adjustments.
The thaw and freeze settings may be raised or lowered to change the temperature of the product. A default
setting of 10 is set at the factory. To decrease the temperature, decrease the numerical setting; to increase the
temperature, increase the numerical setting.
To change the Thaw/Freeze setting:
7.5 No Defrost Time Block
The dispenser has "no defrost" time settings that will prevent it from defrosting during a specified three (3) hour
time block. These settings will affect both barrels and can be programmed under either of the barrel menus. The
“No Def Start 1” and “No Def Start 2” represent the start time setting for each "no defrost" time block.
To program the "no defrost" time block:
1. Scroll down until the desired "no defrost" time menu is displayed and press
the SELECT button.
2.
Press the UP or DOWN buttons until the desired start time is shown (this is
in 24 hour time format).
Example:
1 No Def Start 1 = 3
No defrost from 3 to 6 AM
2 No Def Start 1 = 13
No defrost from 1 to 4 PM
3. Press the SELECT button to save the setting.
1.
In the Settings menu, use the UP and DOWN keys to scroll to the THAW/
FREEZE menu.
2.
Press SELECT key to make the THAW/FREEZE value flash.
3.
Use the UP and DOWN keys to adjust the THAW/FREEZE value to the
desired value.
4.
Press the SELECT key to save the value.
