To install the ACx 601 in a cooling air duct, carry out the following
steps:
1. See Appendix B – Dimensional Drawings for dimensions of the
opening in the duct.
2. Cut the opening.
3. Drill and tap or install appropriate anchors in the mounting bolt
locations at the top and bottom of the opening. It may be necessary
to install angle iron or similar stiffeners to provide mounting points of
sufficient strength and thickness.
4. Frame R2 and R3: Remove the two screws at the lower front edge
of the unit. Lift the front cover somewhat and disconnect the Control
Panel cable from the board fitted on the inside of the cover. Remove
the front and top covers. (See Figure 3-1)
