2 Install the system
2.1 Set up the door panel.
See: QuickGuide-DoorPanel-Cloth or -DoorPanel-Modular
2.2 Connect the yellow tube between yellow ports
marked "Ref B" on fan and gauge. If the fan has a
green port ("B"), connect the green tube.
2.3 Connect the Ethernet cable between fan and
gauge.
2.4 Pass long red tube through the panel. Toss the
end away from the fan’s airstream.
Note : Water in the tube will result in erroneous readings.
1 Prepare the building
2.5 Install the fan.
2.6 Connect the fan power plug to a wall outlet.
