2.2 Select the Door Position on the Metering Box
The Metering Box comes with an adjustable opening which provides 3 ranges of fan flow measurement.
Door Position Flow Range (CFM)
E1 44 -124
E2 21 - 59
E3 10 - 28
The door position (E1, E2 or E3) is determined by the position of the snap pin located on the top of the Metering
Box. The door position can be adjusted by pushing down on the snap pin and sliding the door until the snap pin
reseats into a new position hole.
2.3 Attach the Handle to the Metering Box
A handle is provided which can be attached to the Metering Box using
Velcro strips. You can also screw in your own painter’s pole into the end
of the handle to make it easier to reach exhaust fan grilles mounted high
on walls, or on ceilings.
