F. Prepare two or more gallons of sanitizing solution. Pour half of the solution down the bin and drip tray
drains. After the has completely drained, pour the remaining solution down the drains.
G. Replace the drain strainer.
H. Using a mechanical spray bottle, prepare sanitizing solution and spray the entire interior bin surfaces.
Allow to air dry.
5. Sanitize Tank Systems, Post-Mix and Pre-Mix
A. Remove all ice from the ice bin and melt any remaining ice with hot water.
B. Remove all the quick disconnects from all the tanks.
C. Prepare a mild detergent soap solution in 100
ꢂ
F potable water in a suitable pail or bucket.
D. Submerge all disconnects (gas and liquid) in the soap solution and then clean them using a nylon
bristle brush (Do Not use a wire brush). Rinse with clean water.
E. Prepare sanitizing solution and using a mechanical spray bottle, spray the disconnects. Allow to air
dry.
F. Using a clean, empty tank, prepare five gallons of sanitizing solution. Rinse the tank disconnects with
approximately 9 oz. of the sanitizing solution. Close the tank.
G. Connect a gas disconnect to the tank and then apply one of the product tubes to the tank of sanitizing
solution. Operate the appropriate valve until the sanitizing solution is flowing from the valve.
H. Repeat the step above, applying a different product tube each time until all tubes are filled with the
sanitizing solution.
I.
For post-mix valves, remove the nozzle and syrup diffuser and clean them in a mild detergent soap
solution. Rinse with clean water and reassemble the nozzle and syrup diffuser to
the valve.
J. For pre-mix valves, disconnect all product tubes from the tank of sanitizing solution and then open the
valves to allow the pressure to be relieved. Remove the valves from the dispenser, disassemble and
wash thoroughly in a mild detergent soap solution.
K. Rinse the parts in clean water, reassemble the valve and reconnect it to the dispenser.
L. Allow the sanitizing solution to remain in the tubes for the manufacturer’s recommended exposure
time.
M. Discard the tank of sanitizing solution and connect the disconnects to a tank of potable water. Operate
the valves until all sanitizer has been flushed from the system and only water
is flowing.
N. Connect the disconnects to the appropriate product tanks and operate each valve until all water is
purged from the tubing.
6. Sanitize Syrup Lines, B-I-B Systems
A. Remove all ice from the ice bin and melt any remaining ice with hot water.
B. Remove all the quick disconnects from all the B-I-B
containers.
C. Prepare a mild detergent soap solution in 100
ꢂ
F potable water in a suitable pail or bucket.
D. Submerge all disconnects in the soap solution, then clean them using a nylon bristle brush (Do Not

F. Rinse the B-I-B disconnects in the sanitizing solution.
G. Sanitizing fittings must be attached to each B-I-B disconnect. If these fittings are not available, the
fittings from empty B-I-B bags can be cut from the bags and used. These fittings open the disconnect
so the sanitizing solution can be drawn through the disconnect.
H. Place all the B-I-B disconnects into the pail of sanitizing solution. Operate all the valves until the sani-
tizing solution is flowing from the valve.
I.
Remove the nozzle and syrup diffuser from the valve and clean them in a mild detergent soap solu-
tion. Rinse with clean potable water and reassemble the nozzle and syrup diffuser to the valve.
J. Allow the sanitizing solution to remain in the tubes for the manufacturer’s recommended exposure
time.
K. Remove the sanitizing fittings from the B-I-B disconnects and place them in a container of potable wa-
ter. Operate the valves until all the sanitizing solution has been purged from the tubing.
L. Connect the disconnects to the appropriate B-I-B container. Operate the valves until all water has
been flushed from the system and syrup is flowing freely.
