SPRAYER COMPONENTS & USE INFORMATION, Continued
BASIC USE OF MIXES ON EXIT™ SETTING ADJUSTMENT
Set sprayer knob adjustment to desired amount of concentrate sprayed per gallon. Fill Chemical tank with
exact amount of chemical to cover the square footage per Chemical manufacturer's instructions. Example:
1 ounce for 10 square feet. Evenly spray and cover the desired 10 square foot area until concentrate tank is
empty. Note: Setting 1 will mix less chemical with water - setting 7 will allow more concentrate to be mixed
with water when spraying. The water is the vehicle in which the chemical is being delivered. As long as
you cover the desired predetermined area with the appropriate amount of chemical the amount of water is
inconsequential. Setting the mix ratio helps you control how quickly the chemical is delivered per gallon.
FINE TUNING YOUR MIXES ON EXIT™ SPRAYER
(Use this process for calibrating your mix ratio settings)
1) Fill the concentrate tank and backpack tank - both with water.
2) Weigh the Concentrate tank and record the weight.
3) Set the dial to the desired position (example: set to 1 for 1 ounces per gallon).
4) Weigh your empty bucket (record the weight for future reference if your scale doesn't have a
tear function).
5) Keeping the bucket on the scale, spray 1 gallon of water (adding an additional 8.34 lbs to the
empty weight of your bucket).
6) As you spray, keep your pump strokes consistent for most accurate measurement.
7) Remove the concentrate tank from the backpack sprayer and weigh the tank with it's remaining
chemical in the tank.
8) Subtract the current weight of concentrate tank from the weight recorded in step 2.
9) Calculate the mix ratio using the following equation:
Mix Ratio =
10) If results are slightly off from the expected mix ratio,
set knob –/+ to accommodate variance and retest to confirm accuracy.
Once confirmed note setting that provides exactly 1 ounce per gallon.
11) Repeat as needed for a range of settings
NOTE:
• Always follow chemical manufacturer's instructions.
• When not spraying, set mix ratio dial to zero.
• Approximate mix ratios based on chemical concentrates
with approximate viscosity to water while pumping at a
rate of 60 beats per minute.
• Pumping faster than 60 BPM will result in higher mix ratios
and pumping slower will result in lower mix ratios.
