OPERATING AND ADJUSTMENTS
Explanation of terms
All descriptions related to dispensing heads, dispensing buttons,
pump motors such as: push button #1, dispensing head #2, pump
motor #3 etc. are used in relation to the front of the machine. This
relates also to all components inside of the machine that are
symmetrically positioned. (See Figure C)
For example:
Push button #1 - Far left positioned dispensing push button.
Push button #4 - Far right positioned dispensing push button.
Dispensing head #3 - All components involved when dispensing
caused by depressed push button #3.
Pump motor #4 - Pump motor that works when push button #4 was depressed and is positioned inside the
machine in line with push
button.
Brix Setup
If initial concentrate brix is 60 and required mixing ratio is 6+1/6:1 (6 ounces water to one part concentrate),
then brix of ready to drink mixture of a concentrate and water should be 10.
To measure brix level, a refractometer is used to show sucrose content in a drink by measuring change of the light
diffraction in the water caused by change of viscosity due to sucrose content.
The correct ratio is achieved by controlling water and a concentrate flow to the mixing device, in this case mixing
chamber. Brix on each dispensing head is preset in the factory. In the field, the brix needs to be fine-tuned to the
