VentStop V.C.U Step 6

Lower down all 4 sides, make sure they are as flat as possible and there are no large rocks underneath. Check orientation. Step 8

Roll out back and front, inflation point must be on the front side. Quickly check condition of gate sides to ensure there are no sharps or other issues.

One person at each end, pull the Ventstop so it is as flat as possible, Un-fold top fabric from centre out to side wall and repeat other side. Ensure you end up with an even square shape.

When the unfolding is complete, re-check orientation. Step 9

Blow out your Air line, check to ensure you have Safety clips. Clamp the Venturi to the inflation flange with air flow pointing towards the Ventstop. Keep open end of Venturi off the ground. Step 15

Attach the air line to the quick connect fitting on the venturi, Keep the tap on the Venturi turned off.

Place the control box in a suitable location, and check that all taps inside the box are turned off before connecting.

You can assist the Ventstop by pulling down on the pulley ropes if these are available, or by pulling top corners away from the side wall.

Before full inflation is achieved check the orientation of the Ventstop Adjust top corners if required. Step 33

With Ventstop fully inflated and in the desired position, you have 2 choices, To operate directly from the Venturi, or operate via the control box. Step 34-35

If you are running directly from the Venturi, check that the Venturi has equalised, place hand over open end of Venturi, air should not be blowing or sucking. Step 36
