WARNING: CO
2
displaces oxygen. Strict attention must be observed in the prevention of
CO
2
(carbon dioxide) gas leaks in the entire CO
2
and soft drink system. If a CO
2
gas leak is
suspected, particularly in a small area, immediately ventilate the contaminated area before
attempting to repair the leak. Personnel exposed to high concentration of CO
2
gas will experience
tremors which are followed rapidly by loss of consciousness and suffocation.
NOTE: To readjust CO
2
regulator to a lower setting, loosen adjusting screw lock nut, then turn screw to
the left (counterclockwise) until pressure gage reads 5 psi lower than new setting will be. Turn the
adjusting screw to the right (clockwise) until the gage registers new setting, then tighten the lock nut.

ADJUSTING DISPENSING VALVES WATER FLOW RATE
(see Figure 8)
1. Remove cover from the dispensing valve by lifting the front cover up 1/4 inch and pulling forward.
2. Install syrup diversion tube assembly on the dispensing valve by pushing rubber end of the syrup diversion
tube onto the syrup outlet of the inner nozzle.
3. Measure the water flow rate by dispensing water into a graduated cup for a set period of time.
NOTE: Adjusting screw stops are built into the valve to prevent leakage when the screws are adjusted
too far clockwise. Stop adjusting clockwise when turning resistance increases. Turn the screw
counterclockwise 1--1/2 turns after the stop are contacted.
4. Turn the water flow regulator adjusting screw to the left (counterclockwise) to decrease the water flow rate
or turn the adjusting screw to the right (clockwise) to increase the water flow rate, then recheck the flow
rate. Adjustments should be no more than 1/4 turn at a time.
5. Remove syrup diversion tube from the dispensing valve, then install cover on the dispensing valve.
