2.4 EVERY SIX (6) MONTHS
Clean and sanitize the unit using the appropriate procedures (outlined in Section 3).
NOTE:
Because of difficulty in rinsing, detergent solution should not be introduced into the
carbonator.
2.5 YEARLY
A. Clean water bath interior, including evaporator coils and refrigeration components.
B. Clean the entire exterior of the unit.
C. Sanitize syrup lines.
3. DISPENSER CLEANING AND SANITIZING
3.1 AMBIENT PROCESS
A. The ambient process is the most common method for cleaning and sanitizing dispenser
equipment. The detergent should be caustic-based and the sanitizer should be low pH (7.0)
chlorine solution.
B. Disconnect syrup containers. Remove product from tubing by purging with carbon dioxide.
C. Rinse the lines and fittings with clean, potable room temperature water to remove all traces of
residual product.
D. Fill lines with a caustic-based (low-sudsing, non-perfumed, and easily rinsed) detergent solution.
The solution should be prepared in accordance with the manufacturer’s recommendations, but
should be at least 2 percent sodium hydroxide. Make sure the lines are completely filled and
allow to stand for at least 10 minutes.
E. Flush the detergent solution from the lines with clean water. Continue rinsing until testing with
phenolpthalein shows that the rinse water is free of residual detergent.
F. Fill the lines with a low pH (7.0) chlorine solution containing at least 50 PPM (50 mg/L) available
chlorine. Make sure that lines are completely filled and allow to stand for 10 minutes.
G. Reconnect syrup containers and ready Unit for operation.
H. Draw drinks to refill lines and flush the chlorine solution from the dispenser.
I. Taste the beverage to verify that there is no off taste.
3.2 ALTERNATE CLEANING AND SANITIZING AGENTS
A. The above approach to cleaning and sanitizing is strongly recommended. However, the Division
Quality Assurance Manager may approve the following cleaning and sanitizing agents.
B. Chlorinated alkaline detergents. These compounds may be used as the cleaning agent, but may
not be used as combined cleaner/sanitizer.
7
C. Iodophors may be substituted for chlorine as the sanitizing agent.
D. Quaternary ammonium compounds may be used as a combined cleaner-sanitizer, but are
generally not recommended. These compounds are not to be utilized at concentrations
exceeding 200 PPM (200 mg/L), or that concentration specified in local regulations, which ever
is lower.
!
WARNING
IODOPHORS AND QUATERNARY AMMONIUM COMPOUNDS (QUATS) ARE
BROAD CLASSES OF COMPOUNDS. SOME MEMBERS OF EACH GROUP CAN CAUSE
SERIOUS PROBLEMS WITH FOAMING, DISTORTION OR DISCOLORATION OF POLYMERIC
PARTS, POOR RINSIBILITY, AND OFF TASTE. THE RINSIBILITY AND OFF TASTE
PROBLEMS HAVE BEEN ESPECIALLY PREVALENT WITH QUATS. BECAUSE OF THE
POTENTIAL PROBLEMS, APPROVAL MUST BE GRANTED BY THE DIVISION QUALITY
ASSURANCE MANAGER TO SPECIFIC COMPOUNDS. THIS APPROVAL SHOULD BE BASED
UPON TESTING IN THE LABORATORY.
