buttons located on the control panel. The machine may correct any problems with drink quality after
going through a defrost cycle.
1. After the defrost and refreeze cycle, the compressor may cycle on and off several times to
ensure that the product is uniformly frozen. Wait several minutes, and dispense several drinks,
before judging the quality of the product.
2. The product should freeze to a proper frozen texture, thaw, and refreeze to the same general
texture. The compressor turns on when the thawed product requires refreezing and shuts off
when the product is frozen enough.
3. If the product is freezing too cold (below 24°F), the THAW - FREEZE value may be increased.
If the product is not cold enough (above 28°F), the THAW - FREEZE value may be decreased.
Use the recommended settings that follow when making adjustments to the THAW - FREEZE
value.
11.2 CHANGING THAW AND FREEZE SETTINGS
The THAW-FREEZE values should only be changed if the drink quality is not as expected. Use the
following steps to change THAW-FREEZE settings as necessary. Before changing the THAW-
FREEZE settings, verify that the brix and level control settings (see Section 10.1) are properly set.
THAW-FREEZE settings may not need changing if corrections are made to the level control settings.
A. Changing the THAW-FREEZE values
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 left side of the panel (press the
unmarked button in the center of the panel for the 563). “Machine Settings” displays.
2. Press “SELECT” and the “FWD” until you see the chamber you want to change.
3. Press “SELECT” and “LEVEL CONTROL” displays.
4. Press the “FWD” button until “THAW-FREEZE” displays.
5. To change the THAW-FREEZE values, press “SELECT” and the number starts to flash.
6. Press “FWD” to change to a higher setting or press the “BACK” button to change to a lower
setting.
7. Once the desired setting displays, press “SELECT” to save the new value.
8. To change settings for the other chambers, press “CANCEL” and the “FWD” until desired
chamber is displayed and press “SELECT.” Repeat Steps 3-7 above. Repeat for all chambers
to be adjusted.
9. When settings are complete, press the “CANCEL” button until “Copyright” displays.
12. CRITICAL INFORMATION
The following information is critical to proper machine operation. Prior to troubleshooting problems with the unit,
review the following information.
12.1 CHAMBERS 90% FULL ON INITIAL SET UP
Before beginning a RUN-FREEZE cycle, the chambers should be filled approximately 90% full (up
to relief valve). If the chambers are above the 90% level, with Fill Off, open the dispensing valve
and allow a small amount of liquid to drain out. If the chambers are not 90% full, press “OFF”, then
“FILL”, and then slowly pull the vent ring on the faceplate to vent gas, and allow liquid to fill. The
screen will display “Filling”. Fill slowly and do NOT let the pressure drop more than three to four
(3-4) psi.
12.2 LINE VOLTAGE DROP
The FBD562 and FBD563 units require a separate electrical circuit complete with a 20 Amp breaker or
fuse on a 20 Amp service. The FBD564 unit requires a separate electrical circuit complete with a 30 Amp
breaker or fuse on a 30 Amp service. The units will not function properly if the line voltage drops more
than 10 volts between the power source and the machine.
12.3 LONG TUBING RUNS
A. Long runs of supply tubing can cause problems if the pressure drop (between the CO
2 tank or syrup
source and the unit) is too much. Runs longer than 25 feet (7.62 m) will require special attention.
The machine’s sensors may indicate that the machine is out of syrup, water, or CO2. Consider the
following solutions:
1. Increase the tubing size from 3/8 inch diameter to 1/2 inch diameter.
