Co2 Pressure Specs:
*** Co2 displaces oxygen, this is an asphyxiation risk. Use great care when changing cylinders, always secure cylinders to the wall with a chain or strapping device.
Coca Cola: High pressure Co2 setting for the carbonator is 110 Psi.
Low pressure Co2 setting for the BIB pumps are 65 Psi.
Pepsi: High pressure Co2 setting for the carbonator is 100 Psi.
Low pressure Co2 setting for the BIB pumps are 60 Psi.
It’s a good idea to have the Co2 system leak tested a few times a year, especially if you are using bulk Co2. This will ensure your not spending too much on gas and also could eliminate a potentially dangerous asphyxiation situation.
Water Pressure: Water pressure should not exceed 65 Psi for any carbonator.
Softened water can not be used to supply a carbonator, softened water will inhibit carbonation.
Water is 85% of a fountain beverage, any time you have the availability to filter the water to a soda system it’s a good idea.
System Calibration: Soda systems can fall out of calibration for a number of different reasons. You should have each dispensing stations calibration (water to syrup ratio) checked at least twice a year.
System Cleaning: Although soda lines don’t typically need to be cleaned, you should be cleaning the nozzles and diffusers for each valve and or soda gun daily. Proper cleaning should be done with a small brush and warm water. Soaking nozzles and diffusers overnight for cleaning is a myth and does not clean the parts. You need warm water and agitation to remove sugar from these components.
NEVER use bleach to clean soda system parts!
This includes nozzles, diffusers and drain pans. Bleach can be absorbed into the plastic components; this can lead to drink contamination and will weaken the plastic making it brittle.
