5.4 Filling Barrel and Starting
The barrel, or freeze chamber, must be purged of air before filling with product. Purge the air by activating the gas solenoid
and then using the relief valve on the faceplate ( Figure 5.3 ) to relieve air until all air has been displaced by gas*. Failure to
displace the air with gas will result in poor drink quality.
* Remember to deactivate gas solenoid upon completion.
1
Navigate to the SERVICE MENU and then select the MAINTENANCE MENU. Go to the PURGE/FILL/
DRAIN BARREL menu.
2
Highlight the desired barrel and then press the GAS PURGE button. Follow the prompts until the
process has completed.
3
Press the FILL BARREL button to begin filling with product. Follow the prompts until the barrel
is full (about 90% of the barrel) and then press the END button. Use the relief valve to relieve
pressure in the barrel (
Figure 5.3
).
4 Once all barrels have been filled, return to the home menu.
5
Defrost the barrel(s) by pressing the green check mark button then selecting DEFROST. This will
defrost the highlighted barrel and establish “baseline.”
6
If you want to proceed to a freeze cycle right after the defrost cycle then press the green check
mark button again and select ON.
7
When the LCD display shows READY, the barrel is ready to be conditioned. Dispense several drinks
until lighter color product begins forming in the faceplate.
