Injection Quill Installation

Turn off chemical feed pump. Install thread or teflon compound to 1/2" or 3/4" NPT end of male half. Thread male half nozzle into pipe line at determined location #1 using crescent wrench. Tighten to a snug fit.
Connect chemical feed line to tube fitting, location #2. Cut the tubing end squarely and remove the internal and external burrs.
Insert the tubing through the back of the nut all the way through the nut assembly to the tube stop in the fitting body (see illustration bottom right). If the tubing does not enter the nut easily, loosen the nut one turn and then insert the tubing all the way to the tube stop in the fitting body.
Turn the nut hand tight.
Wrench tighten the nut 1-1/2 - 2 turns.
All nuts must be retightened when the system reaches projected operating pressure.
Restart chemical feed pump and check for leaks.

Note: A pipe wrench is not recommended for use on PVC units.
