Application Optimization (repeat for each application)
• Application too wet
o Increase air
o Reduce injector size (decreases water)
o Increase metering tip (increases chemical)
• Application too dry
o Decrease air
o Increase injector size (increases water)
o Decrease metering tip (decreases chemical)
• Nozzle sputters
o Decrease air
o Decrease nozzle(s) and/or size used on arch
o Increase injector size (increases water)
• Too much chemical used
o Decrease metering tip
o Decrease metering tip and injector size (to maintain desired ratio)
• No chemical
o Check vacuum of injector (see instructions on page 9)
o Check foot valve
o Check metering tip
•
Nozzle fan pattern not filled
o Reduce nozzle size
o Increase injector size (increases water)
•
Water not present at all nozzles on arch
o Verify check valves are functioning
o Verify nozzles are not plugged
o Reduce number of nozzles
o Reduce nozzle size
o Increase injector size (increases water)
Chemical Usage Measuring
Verify titration of chemicals before proceeding
1. Setup lab scale with small bucket of chemical to be measured.
2. Put the suction line into the bucket.
3. Run the application being tested to “prime” the line. (All air bubbles must be removed for accuracy)
4. Record the Initial Weight from the scale. (Tarring the scale with weight on the scale can affect accuracy)
5. Run the application for 6 vehicles (or manually for the same it would be on for 6 vehicles).
6. Record the Final Weight from the scale.
7. Subtract the Initial Weight from the Final Weight to determine the weight of used product.
8. Divide this Used Weight by 6 to get a per car weight.
9. Divide the Per Car Weight in grams by the specific gravity of the chemical to determine the milliliters of chemical
used per vehicle.
10. Repeat for each chemical application.
