dispenseIT Manual – Tuning Applications

Injector Sizing #

• Your dispenseIT arrives configured from the factory. Each function will have the appropriately sized injector pre-installed based on the customer submitted configuration form
• Install metering tips into the barb of the injector (fig. 17.1)
  • Consult your chemical solutions provider for dilution rates. Use the charts below as a reference for selecting the appropriate size metering tip based on injector size
• Install a ¼” chemical compatible hose from the chemical barrels to the injector barb (fig. 17.2)
  • Install chemical compatible foot valves for each function on the draw side of the hose. (The part of the hose that rests inside of the product barrel) 
    • Recommended: Use a 3’ piece of PVC pipe for the line to run through to keep the suction straight down in your chemical barrel (fig. 17.3)

• Refer to the troubleshooting guide on page 21 if
  • an injector is not drawing any chemical
  • an injector draws the chemical for only a brief moment
  • an injector has a low but consistent vacuum chemical draw 
• Refer to the applicator chart below for a starting point
