6.4 Filling Barrel and Starting
NF*
The barrel, or freeze chamber, must be purged of air before filling with product. Purge the air by activating the CO2
solenoid and then using the relief valve (
Figure 6.3
) on the faceplate to relieve air until all air has been displaced by CO2.
Failure to displace the air with CO2 will result in poor drink quality.
* Refer to Appendices for additional information on Nitrofub configuration.
Remember to deactivate CO2 solenoid upon completion.
§ Faceplate available as standard or ADA version (ADA version shown).
