My drink is flat!
The drink temperature may be too warm. Check to ensure there is an ample supply of ice in
the storage bin and that the cold plates are not exposed. (They must be covered by ice.)
Why is my beer foamy?
There could be several causes of over-carbonated, foamy beer, including:
the beer temperature is too warm, the gas pressure on the keg is incorrect,
the blend of carbon dioxide and nitrogen gas is incorrect, or there could be
obstructions in the beer line. Please consult NuCO2 immediately to
help you resolve this problem.
Why is my beer flat?
There could be several causes of under-carbonated, flat beer, including:
the beer temperature is too cold, the gas pressure on the keg is incorrect, or
the blend of carbon dioxide and nitrogen gas is incorrect.
Please consult NuCO2 immediately to help you resolve this problem.
One drink tower is not functioning.
This is not a problem caused by your carbon dioxide system.
Contact your fountain soft drink service agent for assistance.
Is my bulk tank empty?
Locate the gauge at the top center of the tank. It is a typical fuel-gauge-style meter shaped
like a small square, half moon or upside down test tube, and it reads Empty, 1/4, 1/2, 3/4 and Full.
There are two other round gauges on the top of the tank. One supply gauge reads 0-160 psi
or 0–200 psi. The vessel pressure gauge reads 0–400 psi.
If the supply gauges reads 90 or less and/or the vessel pressure gauge reads 100 or less,
the tank does not have enough pressure to push carbon dioxide.
Please contact NuCO2 at 1-800-472-2855.
Be prepared to supply all three readings to the Customer Care Center representative
when you place your call: 1.) Supply Pressure Gauge 2.) Vessel Pressure
Gauge and 3.) Contents Gauge.
My tank was recently filled and it quickly ran out of carbon dioxide.
When an empty bag-in-box syrup container is left connected, the pump may operate continuously,
causing carbon dioxide to be wasted and potentially emptying the bulk system.
Solution: Each time a bag-in-box syrup container is replaced,
the fitting should be cleaned thoroughly in warm water to remove syrup buildup.
This allows the check valve in the fitting to close when the bag-in-box is empty or removed.
The liquid bulk carbon dioxide system feeds all of your carbonated drink dispensers,
including soft drinks, draught beer, frozen drinks and juices. Should a downstream leak occur, carbon dioxide will be wasted and may empty the bulk system.
Solution: Contact your dispenser agent to have the leak repaired.
I see frost on the tank.
Frost is normal during times of high carbon dioxide demand, such as peak business periods. However, should the frost not melt, there might be a leak in the beverage system.
The most common causes of this are an empty bag-in-box syrup container connected to the drink system or a faulty pressure-building regulator.
I hear a hissing sound coming from the tank.
Does it appear that the noise is coming from the large brass barrel on top of the tank?
Yes: You should see a tube coming off this brass barrel that is fed to the outside of
the building. Look at the 0-400 psi gauge. If the gauge is reading 280 psi or higher, the system is
operating normally. The tank is designed to vent pressure and is working correctly.
If the reading is below 280 psi, please call NuCO2 at 1-800-472-2855 for assistance.
No: Try to determine where the noise is coming from. Follow the carbon dioxide lines down
to your fountain soft drink and/or draught beer systems. If you find any type of leaks "down stream,"
you need to contact your beer or soda provider. Note: If there is a significant leak down stream,
this could result in a whistling noise coming from the carbon dioxide tank regulator because the leak
is pushing a higher than normal amount of carbon dioxide through the regulator.
If you witness "fog" that appears to be coming off the tank or any of the tank lines,
stay clear of the tank. If possible, ventilate the area to reduce carbon dioxide concentration
and immediately call NuCO2 at 1-800-472-2855.
If your fountain soft drink carbon dioxide is dispensed through an XactMix beverage control system,
please read How does leak detection help me?
My carbonator is not working.
Check to see that the carbonator is plugged into an electrical outlet.
Call your fountain soft drink service agent.
Is the system leaking?
Frost is normal during times of high carbon dioxide demand, such as peak business periods.
However, the presence of frost just after opening, early in the morning or during slow periods,
or an ever-present ice formation on one side of the tank near the bottom may indicate a leak in
the drink system.
If the ice on your tank is not melting,
please contact a NuCO2 customer care representative at 1-800-472-2855.
