Installation
The MACH-Air™ VAV controller is typically mounted directly
on the sheet metal of an air duct:
! Mount the MACH-Air™
VAV controller on the mixing box.
! Clamp the motor to the damper control shaft using the
universal U-bolt clamp assembly.
! Secure the controller using the self-tapping metal screw
supplied with the MACH-Air™ VAV controller.
! Attach the two differential pressure tubes to the flow sensor
spouts on the MACH-Air™ VAV controller. High pressure
goes to the red spout and low pressure goes to the
unmarked spout.
! Attach power wiring, network wiring, and I/O wiring.
Ground yourself before touching
the controller to avoid damaging
the electronics. Touch a grounded
metal surface to discharge static
electricity.
