How to Change the Metering Tip
• Remove the chemical feed hose from the barb on the side of the proportioning valve.
• Unscrew and remove the old tip.
• Screw in the proper tip for your chemical tip and place the hose back on the barb.
Metering Tip Kit
The Metering Tip Kit contains 14 different colored metering tips, allowing dilution rates
from 11:1 up to 427:1. Refer to the chart below to select the tip that meets the dilution
rate for your chemical application.
• For example, if you require 1-1/2 ounces of chemical per gallon of water, change to
the red metering tip with the dilution rate of 85:1.
• The dilution rates are based on chemicals with water-like viscosity. Thicker (more
viscous) chemicals will dilute at a different rate.
• DO NOT use powdered chemicals in the machine. Use of powdered chemicals will
void your warranty.
• Contact your distributor if you have questions about your chemical.
