DILUTION RATIO CHART
The dilution ratio can be achieved by using one of the 19 supplied metering tips;
Metering tips have small openings of decreasing diameter and are distinguished by different colors.
Table 1 below shows the dilution ratio’s of the various colored tips assuming chemical viscosity of 1 cps (water thin)
(Water supply pressure and flow rates will vary so adjustments in the field may be necessary)
The dilution ratios refer to a static pressure of
50PSI with products
having a viscosity of 1 cps

Table 1 – The dilution values given in this table are measured at a flow rate of 8 gpm and a supply
pressure of 50psi with a delivery hose of 15.24 m (50 ft).
The values in the table should be considered only as a reference, as they are dependent on many variables such
as water flow rate, pressure, chemical viscosity, temperature of the water etc.
To obtain a proper dilution it is recommended to perform the calibration as follows:
1.
Fill a graduated container with the chemical product.
2.
Using the Table 1, select and insert the metering tip closest to the desired dilution ratio for the product.
3.
Insert the suction hose into the graduated container.
4.
Select the product to be calibrated by turning the selector to the left or to the right.
5.
Activate the spray gun and discharge into a container until the suction and delivery hoses are completely
full and free of air (check for air bubbles at the input and for a steady output stream).
6.
Mark the level in the graduated container.
7.
Turn on the spray gun to the maximum and discharge into a 1 liter or 1 gallon container (or other volumes
considering the proportion).
8.
Turn off the spray gun when the container is completely filled.
9.
Read the amount of product in the graduated container.
10. The difference of level between the point 8 and 5 indicates the amount of mixed product per gallon.
11. Repeat the calibration procedure for the other product.
A transparent metering tip is also provided without a pre-drilled opening.
This tip can be manually drilled to obtain a customized degree of dilution.
