SANITIZING POST-MIX SYRUP SYSTEMS

IMPORTANT: Only qualified Service Personnel should perform sanitizing procedure on the post-mix syrup systems.

The post-mix syrup systems should be sanitized every 90-days using a non-scented household liquid bleach containing a 5.25 % sodium hypochlorite concentration. Proceed as follows to sanitize the post-mix syrup sys- tems.

1.Disconnect syrup supplies from syrup systems.

2.Rinse quick disconnects (syrup tanks systems) or bag-in-box connectors (syrup bag-in-box systems) in warm potable water.

STEP 1. WASH SYRUP SYSTEMS

3.Using a clean syrup tank (syrup tank system) or a five-gallon container (bag-in-box system), prepare a full tank or container of liquid dishwasher detergent by using 70_F (21_C) to 100_F (38_C) potable water and 0.5 oz. (15 ml) of liquid dishwasher detergent to one gallon of potable water. Stir detergent solution to thoroughly mix the solution.

4.Syrup Tank Systems.

A.Observe and note CO2 pressure setting on the syrup tanks CO2 regulator, then re-adjust CO2 regula- tor to 60 to 80-psi. Pressurize syrup tank containing detergent solution to 60 to 80-psi.

B.Connect detergent solution tank, pressurized at 60 to 80-psi, into one of the syrup systems.

Bag-in Box Syrup Systems.

C.Install bag valves, cut from empty bag-in-box syrup containers, on ends of syrup containers syrup outlet tubes connectors.

D.Place all syrup outlet tubes, with bag valves on their ends, in container containing detergent solution.

5.Flush the syrup system and dispensing valve as follows:

A.Place waste container under applicable dispensing valve.

B.Activate the dispensing valve for one minute to purge all syrup and flush out the syrup system.

C.Continue to activate the dispensing valve in cycles (“ON”for 15-seconds, “OFF”, then “ON”for 15-seconds). Repeat “ON”and “OFF”cycles for 15-cycles.

6.Connect detergent solution to the remaining syrup systems and flush syrup out of the syrup systems as instructed in step 5 preceding.

7.Remove detergent solution source from the syrup system.

STEP 2. FLUSH SYRUP SYSTEMS

8.Syrup Tank Systems.

Connect syrup tank containing potable water, pressurized at 60 to 80-psi, into one of the syrup systems. Bag-in-Box Syrup System.
