Installation Information for 150psi Rated Retractable Injection Quills

Applies to EB-120, EB-130, EB-132, EB-145, EB-146, EB-159, EB-160, EB-162, EB-164, EB-165, EB-191

 

REMOVAL AND INSTALLATION DEMONSTRATION

 

PRECAUTIONS

Injection quills are designed to deliver a chemical solution feed to the interior of a pressurized water/process main. The following precautions should be taken to ensure proper and safe installation:

  • Become familiar with the components of the injector as listed below.
  • Verify that the injector being installed is compatible with the intended chemical feed.
  • Ensure that the Restraint Chain and Restraint Hook are secured while the injector is under pressure. Do not rely on the Compression Gland to restrain the Solution Tube from retracting while in operation.
  • Do not over tighten the Compression Gland. Tighten only to the point where any leak stops. Over tightening the gland can, over time, cause damage to PVC/CPVC Solution Tubes as well as the Compression O-ring.
  • The pressure rating listed for this unit is the maximum operating pressure. It is highly recommended that the pressure in the main be reduced to an appropriately safe level before inserting or retracting the solution tube.
 

INSTALLATION INSTRUCTIONS  

WARNING: SAF-T-FLO injectors are shipped in their operating position. Removal of the solution tube may be required prior to installing the injector onto the main.

Step 1: Remove the Solution Tube

  • Loosen the Packing Nut by turning counter-clockwise.
  • Release the Safety Hook from the Restraint Chain.
  • Retract the Solution Tube from the Main Connection Assembly until the Limit Chain is completely extended. Loosen the Packing Nut more if needed.
  • Close the valve of the Corporation Stop/Ball Valve. If the valve does not want to close, ensure the Solution Tube has been retracted far enough so that the tip of the tube is not obstructing the valve from closing.
  • With the valve closed, disconnect the Limit Chain from the Threaded Connector and completely remove the Solution Tube.

Step 2: Install the Corporation Stop/Ball Valve

WARNING: Do not use a pipe wrench to install the corporation stop/ball valve.
  • Apply suitable thread sealant to male threads of the Main Connection thread and install into desired location.
  • Make sure the Corporation Stop/Ball Valve is in the closed position.

Step 3: Install the Solution Tube

WARNING: For injectors not provided with a check valve, make sure to provide a suitable form of isolation to prevent back flow from the solution tube prior to opening the corporation stop/ball valve.
  • Insert the outlet end of the Solution Tube into the Packing Nut until the tip is stopped by the closed valve.
  • Connect the Limit Chain to the Threaded Connector and close the jaw of the Threaded Connector.
  • SLOWLY OPEN the Corporation Stop/Ball Valve and begin to slide the Solution Tube down into the main. If water begins to leak past the Packing Nut, tighten until the leak stops.
  • Keep inserting the Solution Tube until the Restraint Chain can be attached to the Restraint Hook. Connect the Chain to the Hook. Slowly allow the pressure to push back against the solution tube until the Restraint Chain/Hook is tight.
