d) Slip the ceramic weight over the Supply Tubing so it rests on the Foot Valve
e) Attach the required Metering Tip end of the tubing
(see Chemical Injection Adjustments , below)
f) Insert the foot-valve end of the tubing into the chemical container

PERATION
1. Turn on the main water valve
•
At least 15 PSI water pressure must be available to operate the proportioner
•
As the tank fills, a certain amount of chemical concentrate will be drawn up thought the plastic
tubing, based on the metering tip used, and mixed with the incoming water
2. When the fluid level in the tank reaches 1-2 inches below the top of the float, the valve should close
3. If the tank level drops more than roughly four inches, the valve will open

DJUSTMENTS
Refer to Tables 1 , 2 , or 3 below, for dilution ratios of various chemical viscosities.
CAUTION: Use care when handling hazardous chemicals
•
Specific Metering Tips are used to control chemical feed rates
•
For very viscous products, the induction rates can be increased by substituting 1/2" ID inlet
tubing. Be sure to leave a short piece of 3/8" ID tubing on the proportioner and foot valve
barbs, as bushings
Note: Induction rates are based on a water pressure of 40 psi
1 cps (centipoise) is equal to the viscosity of water
75 cps is approximately equal to the viscosity of 10-weight motor oil
200 cps is approximately equal to the viscosity of most dishwashing detergents
