MIX RATIO ADJUSTMENTS(cont.)
7.If the time observed is too short or long, turn the needle valve clockwise or counterclockwise, respectively, a little at a time. Repeat from the preceding step until correct.
Mix ratio (water/flavor) | Time for FLAVOR OUTPUT (1/2 cup) | Time for WATER OUTPUT (1 cup) |
|
|
|
1+1 | assume 20 sec. or obtain time per note below | 40 sec. or 2 times flavor output time |
|
|
|
2+1 | assume 20 sec. or obtain time per note below | 20 sec. or equal to flavor output time |
|
|
|
3+1 | assume 20 sec. or obtain time per note below | 13.3 sec. or 0.67 times flavor output time |
|
|
|
4+1(see below) | assume 20 sec. or obtain time per note below | 10 sec. or 0.5 times flavor output time |
|
|
|
5+1 | assume 20 sec. or obtain time per note below | 8 sec. or 0.4 times flavor output time |
|
|
|
6+1 | assume 20 sec. or obtain time per note below | 6.7 sec. or 0.33 times flavor output time |
|

NOTE: For a typical adjustment, the time for flavor output in the center column above is assumed to be 20 seconds. A more specific flavor pump output time may be obtained prior to adjustment of the needle valve. To do so, connect the flavor to be tested to the “FLAVOR INPUT”, and the test hose to the corresponding “FLAVOR OUTPUT” (make no connection to the “WATER INPUT”). With a
Formula for setting mix ratio: To obtain the time for dispensing 1 cup of water, divide the time it takes to dispense
Example: W=2(F/X) Where W is the time it should take to dispense one cup of water, it took F seconds (20 here) to dispense 1/2 cup of flavor concentrate, we desire a mix ratio X of 4+1 (X will be the first number in the mix ratio, 4).
Therefore: | W = 2/(20/4) |
| W = 2/5 |
| W = 10 seconds |
So if it took 20 seconds to dispense
