6 | Close the "A" chemical (red) valve on the F1000 dispenser, leaving the "B"
chemical (blue) valve open.

7 | Place a 32 oz. paper cup on a scale, and tare the scale to read zero.
8 | Using a stop watch, or optional timer, trigger the F1000 dispenser for exactly
3 seconds, directing the flow of the "B" chemical into the paper cup on the
scale. Record the weight of "B" chemical dispensed.
9 | Purge the mix cartridge once again as outlined in step 5 above.
10 | Calculate the A:B chemical ratio by dividing the weight of the "A" chemical
obtained from step 4 by the weight of the "B" chemical obtained in step 8.
Example:
"A" chemical (3 second shot) weighs 41 grams
"B" chemical (3 second shot) weighs 37 grams
41 grams ÷ 37 grams = 1.11 A:B ratio
Most Polypro formulations should be run with an A:B ratio in the range of 1.00
to 1.15. Consult the technical data sheet for the Polypro formulation you are
running- it will list the best A:B ratio for that particular product (See Ratio
Calibration Charts on pages 18 - 21).
11 | If the A:B chemical ratio obtained in step 10 is too high, ie above 1.15,
adjust the nitrogen pressure on the "B" chemical up by 10 psi and repeat the
calibration procedure starting at step 1. If the A:B ratio obtained in step 10 was
too low, ie below 1.00, the adjust the nitrogen pressure on the "A" chemical up
by 10 psi and repeat the calibration procedure. It may be necessary make more
than one adjustment to the nitrogen pressure of the "B" chemical before reach-
ing the correct A:B ratio. It is advisable to adjust the nitrogen pressure on the
B" component in order to adjust the A:B ratio, not the nitrogen pressure on the
"A" chemical.
12 | It may be necessary during the calibration process to reduce the nitrogen
pressure on one of the chemical cylinders. This situation occurs when the proper
A:B component ratio cannot be achieved without raising the pressure on one of
the cylinders to its maximum pressure of 220 psi. REMEMBER: Each of the
chemical cylinders is equipped with a pressure relief valve that will auto-
matically open if the nitrogen pressure on the cylinder exceeds 220 psi.
Use the following steps to reduce nitrogen pressure on the cylinder. SAFETY
GLASSES SHOULD BE WORN DURING THIS PROCEDURE.
