PRODUCT TUBING
Only trained and qualified persons should perform these cleaning and sanitizing procedures.
Sanitize tank systems, Post-Mix and Pre-Mix as follows:
1. Remove all the quick disconnects from all the tanks. Fill a suitable pail or bucket with soap solution.
2. 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.
3. Prepare sanitizing solution and using a mechanical spray bottle, spray the disconnects.
Allow to air dry.
4. Using a clean, empty tank, prepare five (5) gallons of the sanitizing solution. Rinse the tank disconnects
with approximately 9 oz. of the sanitizing solution. Close the tank.
5. Prepare cleaning tank by filling clean five (5) gallon tank with a mixture of mild detergent and potable water
(120_F).
6. Connect a gas disconnect to the tank and then apply one of the product tubes to the cleaning tank. Oper-
ate the appropriate valve until liquid dispensed is free of any syrup.
7. Disconnect cleaning tank and hook up sanitizing tank to syrup line and CO2system.
8. Energize beverage faucet until chlorine sanitizing solution is dispensed through the faucet. Flush at least
two (2) cups of liquid to ensure that the sanitizing solution has filled the entire length of the syrup tubing.
9. Allow sanitizer to remain in lines for fifteen (15) minutes.
10. Repeat the step above, applying a different product tube each time until all tubes are filled with the sanitiz-
ing solution.
11. For post-mix valves, remove the nozzle and syrup diffuser and clean them in a mild soap solution.
Rinse with clean water and reassemble the nozzle and syrup diffuser on the valve.
12. 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 soap solution.
13. Rinse the parts in clean water, reassemble the valve and reconnect it to the dispenser.
14. Discard the tank of sanitizing solution and reconnect the product (syrup or pre-mix) tanks. Operate the
valves until all sanitizer has been flushed from the system and only product (syrup or pre-mix) is flowing.
Sanitize syrup lines, B-I-B Systems
1. Remove all the quick disconnects from all the B-I-B containers.
https://appliancetechmanuals.com

7620919505
2. Fill a suitable pail or bucket with soap solution.
3. 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.
4. Using a plastic pail, prepare approximately five (5) gallons of sanitizing solution.
5. Rinse the B-I-B disconnects in the sanitizing solution.
6. 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 sani-
tizing solution can be drawn through the disconnect.
7. Place all the B-I-B disconnects into the pail of sanitizing solution. Operate all the valves until the sanitizing
solution is flowing from the valve. Allow sanitizer to remain in lines for fifteen (15) minutes.
8. Remove the nozzle and syrup diffuser from each valve and clean them in a soap solution. Rinse with clean
water and reassemble the nozzle and syrup diffuser to the valve.
9. Remove the sanitizing fittings from the B-I-B disconnects and connect the disconnects to the appropriate
B-I-B container. Operate the valves until all sanitizer has been flushed from the system and syrup is flow-
ing freely.
REPLENISHING CO2SUPPLY
NOTE: When indicator on the 1800–psi gage is in the shaded (“change CO2cylinder”) portion of the dial,
CO2 cylinder is almost empty and should be changed.
1. Fully close (clockwise) the CO2cylinder valve.
2. Slowly loosen the CO2regulator assembly coupling nut allowing CO2pressure to escape, then remove the
regulator assembly from the empty CO2cylinder.
3. Unfasten safety chain and remove the empty CO2cylinder.
WARNING: To avoid personnel injury and/or property damage, always secure the CO2
cylinder with a safety chain to prevent it from falling over. Should the valve become
accidently damaged or broken off, a CO2cylinder can cause serious personnel injury.
4. Position the full CO2cylinder and secure with a safety chain.
5. Make sure gasket is in place inside the CO2regulator assembly coupling nut , then install the regulator as-
sembly on the CO2cylinder.
6. Open (counterclockwise) the CO2cylinder valve slightly to allow the lines to slowly fill with gas, then open
the valve fully to back–seat the valve (back–seating the valve prevents gas leakage around the valve
shaft).
7. Check CO2connections for leaks. Tighten any loose connections.
