Once you’re happy with the hanging height of the extraction system, feed the power lead through one of the lower ports, and the ducting through one of the higher ports. Pull the drawstring tight around both ports to keep light in and bugs out.
Now the intake fan can be installed. There's no carbon filter this time round - secure the ducting to both sides of the unit using Quick Release Duct Clips.
Once assembled, you can place your fan on the outside of your tent and feed the ducting through one of your lower ports. Make sure your fan's facing the right way to draw air in (exhaust in).
