CHEMICAL INJECTION ADJUSTMENT
Chemical feed rates are controlled by metering tips screwed into the proportioner barb. Select a tip using the Table
as a guide.
Note: 1cp(centipoise) is equivalent to the viscosity of water, 75 cp is approximately equal to the viscosity of 10
weight motor oil, and 200 cp is approximately equal to the viscosity of most dishwashing detergents.
