APPENDIX A: 372 “NITROFUB”
The 372 “Nitrofub” dispenser, is a unique dispenser with barrel one configured for Nitro-FCB (expanded drink) and barrel
two configured for FUB (drink with no expansion). The second biggest difference from a standard 372 is the Nitrofub
dispenser’s usage of Nitrogen (N2). The following information supplements the information available in this manual to
detail specific requirements and features of the dispenser.
A1. SAFETY
A1.2 Nitrogen (N2)
In addition to making sure to follow proper safety protocols for CO2 as stated in Section 1.2, strict attention must also be
observed in the prevention of N2 gas leaks in the frozen drink system. If an N2 gas leak is suspected, immediately ventilate
the contaminated area before attending to repair the leak. Inhalation of excessive amounts of N2 can cause dizziness,
nausea, vomiting, loss of consciousness, and death.
To avoid personal injury and/or property damage, always secure N2 cylinders in an upright position with a safety chain. An
N2 cylinder with a damaged or detached valve can cause serious personal injury.
