Batch Dispense or
Ratio Check
Batch dispense is always 1 pint (500 cc) of total
volume, regardless of ratio setting.
Follow this procedure to dispense a batch (into one con-
tainer) or verify a ratio setting (use separate container
for fluid A and B). Dispense into a container with gradua-
tions no greater that 5% of each component.

3.
Close sampling valve H
4.
Dispense fluid B:
a.
Batch dispense: move the 1 quart (1000 cc)
container under sampling valve H
Ratio check: place clean 1 quart (1000 cc) con-
tainer under sampling valve H
On higher ratio settings, use a smaller container for
more accurate readings.
b.
Slowly open and adjust sampling valve H
achieve desired flow. The pump stops automati-
cally when dispense is complete. Indicator B
turns off.
5.
Batch dispense: stir material until mixed.
Ratio check: compare A and B fluid dispense.
