Chemical Injector Operation
2. Push end of chemical injector hose over chemical injector fitting on
pump. Place other end in container of chemical solution.
3. Install the black, large–orifice, chemical tip. (Installing and Changing Spray Tips page 12).
4. Trigger gun for a few seconds. Chemical solution will begin mixing in spray pattern.
The large orifice of the chemical tip causes a drop in pressure that actuates the chemical injector.
Changing back to a small orifice spray tip deactivates the chemical injector and produces high pressure
for rinsing. The chemical filter can be left in the chemical container during high–pressure use.
