Optimizing the System
Consistently achieve the desired cleaning and presentation/performance
using the least amount of chemical and water
Injectors vs. Metering Tips vs. Nozzles
The key to optimizing the system is through trial and error.
Don’t be afraid to try these steps to achieve your ideal performance.
What do injectors do?
o
Increases or decreases the amount of water
in the solution
What do metering tips do?
o
Increases or decreases the amount of
chemical in the solution
What do nozzles do?
o
Determines the pattern and backpressure of
the solution
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)
