7.5 Drink Too “Firm” or Cold
A drink that is over-frozen will tend to be very cold, below 22°F (-5.5°C), and can be considered hard and difficult to suck
through a straw. It can also be lighter in weight than a properly frozen drink and tends to collapse in the cup after being
dispensed. To raise the temperature of the drink, increase the setting found in the FREEZE ADJUSTMENT menu. It will
take several compressor cycles before the product in the barrel has reconditioned to the new setting.
7.6 Drink Too “Sloppy” or Warm
A drink that is not frozen enough will tend to be above 27°F (-2.8°C) and will be considered “wet” or “loose” and may not
stand up in the cup. It can also be heavier in weight than a properly frozen drink. To freeze the drink harder, lower the
setting in the FREEZE ADJUSTMENT menu. It will take several compressor cycles before the product in the barrel has
reconditioned to the new setting.
7.7 Drink Too Heavy
NF*
A drink with not enough CO2 will be heavy and may look dark in the barrel. To increase the CO2 content in the drink,
increase the setting in the EXPANSION ADJUSTMENT menu. Approximately ten 16 oz drinks will need to be dispensed
before the product in the barrel has reconditioned to the new setting.
7.8 Drink Too Light
NF*
A drink with too much CO2 will be very light and may even collapse in the cup. To reduce the amount of CO2 in the drink,
lower the setting in the EXPANSION ADJUSTMENT menu. Approximately ten 16 oz drinks will need to be dispensed before
the product in the barrel has reconditioned to the new setting.
7.9 Defrosting
To maintain optimal product quality a frozen drink must be periodically defrosted because ice crystals grow in size over
time and degrade the consistency and texture of the drink. The best drink quality is always right after defrost and refreeze.
Naturally, it is ideal for the dispenser to be ready to serve drinks at all times, so a balance between defrost and up time
must be maintained. During times of high volume dispensing, a barrel can go longer without defrosting while low volume
periods should defrost every three to four hours. Please refer to the “Defrost Schedule Menu” and “Auto Defrost Menu”
sections of this manual for directions on setting up defrost times.
* Refer to Appendices for additional information on Nitrofub configuration.
