Start-Up Procedure for Kongskilde FVO In-Line Venturi
1. Duct system must be completely connected to the intake hoods or hopper(s) and dropout
box or cyclone.
2. The Outlet of the Blower is connected to the side inlet of the FVO Venturi. As well, the side
outlet of the Air Return is to be connected to the Blower inlet.
3. Loosen the clamp on the telescopic orifice tube. This allows it to readily slip in and out of
the Venturi body.
4. Close the Venturi orifice by sliding it into the body of the Venturi.
5. Connect the Manometer or Magnehelic Gauge to the pressure tap on the negative side of
the conveying duct. (This pressure tap should be approximately 60 cm (24") back from the
Venturi body.
6. Start the Motor. (Check for proper rotation).
7. Gradually open the Venturi orifice tube by retracting it out of the Venturi body.
As this is being done, the Manometer negative pressure will rise. When you attain the
maximum negative pressure or desired pressure, shut the blower off and tighten the clamp
on the Venturi orifice.
Note: Opening the orifice too wide will also reduce the negative pressure.
This may require you to slide the orifice in and out until you reach the optimum negative
pressure.
8. Re-tighten the orifice tube clamp.
9. Check motor amperage draw. If you have an over-amp situation, close the orifice tube until
you attain the required amperage draw.
