2. Pour small amount of soap solution on cold plate.
3. Using a cloth, wash down the surfaces of the cold plate with soap solution.
4. Rinse cold plate surface by pouring potable water.
CLEANING THE ICE BIN
1. Prepare a mild detergent soap solution in 100° F (38° C) potable water.
2. Using a nylon (not wire) bristle brush, clean the cold plate and the interior of the ice bin with the soap
solution.
3. Rinse the cold plate and interior bin surfaces with clean potable water.
4. Using a mechanical spray bottle, prepare a sanitizing solution according to the manufacturer’s directions
and spray all of the interior bin surfaces. Allow to air dry.

Sanitize syrup lines, BIB System
1. Remove all the quick disconnects from all the BIB containers.
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 gallons of sanitizing solution.
5. Rinse the BIB disconnects in the sanitizing solution.
6. Sanitizing fittings must be attached to each BIB disconnect. If these fittings are not available, the fittings
from empty BIB bags can be cut from the bags and used. These fittings open the disconnect so the
sanitizing solution can be drawn through the disconnect.
7. Place all the BIB disconnects into the pail of sanitizing solution. Operate the valve until the sanitizing
solution is flowing from the valve. Allow sanitizer to remain in lines for 15 minutes.
8. Remove the nozzle and syrup diffuser from the 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 BIB disconnects and connect the disconnects to the appropriate
BIB container. Operate the valve until all sanitizer has been flushed from the system and syrup is flowing
freely.
REPLENISHING CO2SUPPLY (ASREQUIRED)
NOTE: When indicator on the 1800-psi gage is in the shaded (“change CO2cylinder”) portion of the dial,
CO2cylinder is almost empty and should be changed.
!
DANGER:
CO2displaces oxygen. Strict attention MUST be observed in the prevention of CO2gas leaks in the entire CO2and
soft drink system. If a CO2gas leak is suspected, particularly in a small area, IMMEDIATELY ventilate the
contaminated area before attempting to repair the leak. Personnel exposed to high concentrations of CO2gas
experience tremors which are followed rapidly by loss of consciousness and DEATH.
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 CO2cylinder with a safety chain to prevent it
from falling over. Should the valve become accidently damaged or broken off, a CO2regulator can cause serious
personnel injury or death.
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
assembly 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.

ADJUST WATER-TO-SYRUP RATIO
Figure 1. Water to Syrup Ratio Adjustment
1. Remove valve cover and install syrup separator over the diffuser and through the nozzle.
2. Hold cup under valve and dispense beverage for a specific time (i.e. 2 seconds).
NOTE: Water and syrup must be cold before checking ratios.
3. Adjust carbonated water flow to the desired rate [such as 2 to 3 oz. (59 to 88.5 ml) per second].
4. Turn the flow adjuster 1/4 of a turn at a time and recheck the flow. To increase reading turn clockwise.
5. Set syrup flow adjuster to get the desired ratio.
6. Test the valve and adjust until a consistent ratio is delivered three consecutive times.
