8 FAQS
8.1 POWER ISSUES
If the BeerBlast™ 7/14KPH / N2-GEN™ 7/14KPH does not have power, the production and storage of nitrogen will
become apparent once the storage pressure drops. The taps will begin to pour slowly or not at all.
1. Check the power cord
2. Has the building’s circuit breaker or GFCI tripped? Locate the breaker and reset. If the breaker
continues to trip, you may have that circuit overloaded.
8.2 PRESSURE ISSUES
Whether you are using a BeerBlast™ 7/14KPH / N2-GEN™ 7/14KPH with an integrated gas blender or an N2-
GEN™ 14KPH with an external gas blender, you have to have both gases (N2 and CO2) available with pressures
over 40 psig. Blenders will shut down output if either gas is not present over 40 psig.
The BeerBlast™ 7/14KPH / N2-GEN™ 7/14KPH will produce and store nitrogen at 70 (+/-3) psig. Once the storage
tank reaches 70 (+/-3) psig, the system will go into Stand-By Mode. When the pressure drops by about 7-10 psig,
the system should go into Operation Mode and begin to refill the storage. If you are out of the specifications, we
need to determine where the issue is. Contact the manufacturer or factory trained technician.
CO2 Pressure Check:
If you have a BeerBlast™ 7/14KPH / N2-GEN™ 7/14KPH, look at your CO2 regulator pressure gauge. It should
read between 80 and 100 psig. If it is lower, check the CO2 Storage tank to see if it needs refilling or if the pressure
regulator needs adjustment. The pressure going into the BeerBlast™ 7/14KPH / N2-GEN™ 7/14KPH is
recommended to be set at 80 psig.
Nitrogen Pressure Check:
Look at the pressure gauge on the top of the cabinet. It should be between 50 and 80 psig. If the pressure is low, a
few things need to be checked.
Check the power.
Check for leaks throughout the system. Refer to section on Checking for Leaks.
Pressure Regulation Check:
Lastly, if the CO2 and N2 are both present and the blender is outputting gas, it’s possible a regulator is
malfunctioning or needs adjustment. The mixed gas coming from the blender should be between 40-80 psig
(dependent on the N2 and CO2 pressures going into the blender). A primary regulator is usually installed on the
output lines coming from the BeerBlast™ 7/14KPH / N2-GEN™ 7/14KPH. The primary regulator is there to “step
down” the available pressure to the kegs. There are typically secondary regulators located further downstream on
the mixed gas lines going to the kegs. The secondary regulators are there to individually tune each keg. Some
beers require more/less pressure and regulating each keg individually will allow the beer pouring to be optimized.
If the BeerBlast™ 7/14KPH / N2-GEN™ 7/14KPH is operating correctly, then the restaurant/pub should contact
their Draft Beer System Technician to adjust the regulators for optimal performance.
