Place all bag-in-box syrup containers syrup outlet tubes in container containing potable water.

20.Flush sanitizing solution from the syrup system and the dispensing valve as follows:

A.Place waste container under applicable dispensing valve.

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

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.

21.Repeat steps 19 and 20 preceding to purge sanitizing solution out of the remaining syrup systems and dispensing valves.

22.Remove potable water source from the syrup system.

STEP 5. PURGE WATER OUT OF SYRUP SYSTEMS (RESTORE OPERATION)

23.Syrup Tank Systems.

A.Noting syrup tanks CO2 regulator pressure setting observed in step 4 preceding, readjust CO2 regula- tor to the observed pressure setting,

B.Connect tanks containing syrup into syrup systems.

Bag-in-Box Syrup System.

C.Remove all bag valves from bag-in-box syrup containers outlet tubes connectors.

D.Connect bag-in-box syrup containers into the syrup systems.

24.Place waste container under dispensing valves. Dispense from all dispensing valves to permit syrup to purge all potable water from the syrup systems and the dispensing valves. Continue to dispense from the dispensing valves until only syrup is dispensed from the syrup systems and valves.

WARNING: To avoid possible personal injury or property damage, do not attempt to remove the syrup tank cover until CO2 pressure has been released from the tank.

25.Dispose of waste sanitizing solution in a sanitary sewer, not in a storm drain, then thoroughly rinse the in- side and the outside of the container that was used for sanitizing solution to remove all sanitizing solution residue.

CARBONATOR WATER PUMP YEARLY MAINTENANCE OR AFTER WATER SYSTEM DISRUPTIONS

WARNING: The carbonator water pump water inlet strainer screen and the double-liquid check valve must be inspected and cleaned at least once a year under normal circumstances, and after any disruptions (plumbing work, earthquake, etc.) to the water

supply system that might cause turbulent (erratic) flow of water through the system. A carbonator water pump with no screen or a defective screen in the strainer would allow foreign particles to foul the double-liquid check valve. CO2 gas could then back flow into the water system and create a health hazard.

The carbonator water pump water inlet strainer screen and the double-liquid check valve must be inspected and cleaned at least once a year under normal circumstances and after any water system disruption (plumbing work, earthquake, etc.) as follows:
