Installation Guidelines
Panels, Frame Channels, and Doors
Panel Removal
To remove a side or top panel, remove the flat head Torx 30
fasteners along the sides of the panel. Lift off the panel after
removing all fasteners.
Frame Channel Removal
Frame channels that run the length of the unit along the top can
be removed to allow access to both the side and top of the unit.
To remove the frame channel, first remove the side panel(s).
Once the side panel is off, remove the flat head Torx 30
fasteners in the corner of the frame channels. Then pull the
frame channel out the side. Remove any panel screws that are
within one inch of the of the frame since they are engaged into
the gasketed flange of the frame. See Figure 14.

Fan Section Doors
Note –
Opening fan section doors requires using a 1/2" socket
wrench, which satisfies ANSI standards and other codes
that require the “use of tools” to access compartments
containing moving parts or electrical wiring. See
Figure 15.
