1. Open the box at the top of the machine and you can see the water inlet of the water pump, where you can change the flow rate of water. The water pump is connected to the syrup inlet, where you can change the ratio of syrup to water.

2. Open the valve head of coke machine, and you can see two spiral regulating valves to adjust the ratio of syrup to water.

3. Open the top cover of the three-valve coke machine valve. There is an adjusting knob on the valve head, which can change the proportion of sugar water, with carbonated water adjustment on the left and syrup adjustment on the right. Adjust the proportion of sugar water with a proportional cup. The ratio of Pepsi syrup to water is 1: 5, Qixi is 1: 5, and mirinda is 1: 4.

4. For professional adjustment, it is necessary to use a shunt nozzle. If the syrup temperature of the three-valve coke machine is high and the flow rate is fast, for example, adjust the proportion when the temperature is high.
