4. DISPENSER CLEANING AND SANITIZING
4.1
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 a low pH (less
than 7.0) chloride solution.
B. Disconnect syrup containers and remove product from tubing by purging with water.
C. Rinse the lines and fittings with clean, 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 two (2) percent sodium hydroxide. Make sure the lines are completely filled
and allow to stand for at least ten (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 100 parts per million (PPM)
(100 mg/L) available chlorine. Make sure that lines are completely filled and allow to stand for
ten (10) minutes.
G. Nozzle/Diffuser Sanitizing
Use the following procedure to sanitize the nozzle housing during dispenser sanitization.
1. Cleaning Solution - Prepare a low sudsing, non-perfumed, and easily rinsed detergent
solution and clean, potable water at a temperature of 90° to 110°F.
2. Sanitizing Solution - Prepare a chlorine solution (less than pH 7.0) containing 100 PPM
available chlorine with clean, potable water at a temperature of 90° to 110°F. Any sanitizing
solution may be used as long as it is prepared in accordance with the manufacturer's
written recommendations and safety guidelines, and provides 100 PPM available chlorine.
3. Cleaning Procedure
BE CAREFUL NOT TO GET SANITIZING SOLUTION ON THE CIRCUIT BOARD.
a. Disconnect power, so the valve will not be inadvertently activated while cleaning.
b. Remove nozzle housing by twisting it counter-clockwise and pulling it down.
c. Wash the nozzle housing with the cleaning solution.
d. Immerse the nozzle housing in a bath of the sanitizing solution for 15 minutes.
e. While the parts are in the sanitizing solution, visually inspect around the nozzle
mounting area for syrup residue. Using a cloth or nozzle brush and sanitizing solution,
clean this area and the bottom of the nozzle body.
f.
Wipe off the valve shroud assembly and any other areas that may have been splashed
by syrup.
g. Wearing sanitary gloves, remove, drain, and air dry the nozzle housing.
h. Make certain the nozzle o-ring is in place around the nozzle mounting area on the valve.
If necessary, slide a new nozzle o-ring (PN 02-0228) onto the nozzle mounting area.
(Wear sanitary gloves while handling the o-ring.) If needed, apply 111 lubricant (or
another FDA approved lubricant) to the o-ring.
i.
Wearing sanitary gloves, install the nozzle housing by inserting it into the nozzle body
and twisting it clockwise to lock it in place.
j.
Connect power and replace cover.
k. Reconnect syrup containers and ready Unit for operation.
REMOVE SANITIZING SOLUTION FROM DISPENSER AS INSTRUCTED. RESIDUAL
SANITIZING SOLUTION LEFT IN SYSTEM COULD CREATE HEALTH HAZARD.
l.
Draw drinks to refill lines and flush the chlorine solution from the dispenser.
Please note that a fresh water rinse cannot follow sanitization of equipment. Purge only
with the end use product. This is an NSF requirement.
