Dynon Avionics EFIS-D6 Installation Guide - Manual (Page 21)

Instrument Installation
Installation of the EFIS-D6 main unit should only be completed once all other physical and
electrical installations have been performed. This will ensure that last-minute adjustments will
not have to be made with the EFIS-D6 mounted in the panel.
The diagram above shows the dimensions expected for the proper installation of the EFIS-D6
into your panel using no mounting bracket. All units are in inches. Push the EFIS-D6 through the
main panel hole. The four studs on the back of the EFIS-D6 will fit into the four mounting holes
having dimensions listed in the diagram. Place one of the four supplied washers on each stud
before pushing the EFIS-D6 into place in the panel, putting the washers in between the EFIS-D6
and the panel. Place one of the 4 supplied mounting nuts on the end of each of the 4 studs
protruding from the back of the panel. Secure the nuts tightly against the panel to complete the
installation.
OPTION 2: FLUSH-MOUNT BRACKET
Make a rectangular cutout in your panel, ensuring that it allows the front panel of the EFIS-D6 to
fit. The cutout required should have the dimensions 4.09” wide by 3.39” tall with corner radii of
0.125”. You also need to drill four 0.164” holes in your panel at the four locations shown on the
diagram below (two above and two below the rectangular cutout). Install #6 plate nuts on the
back side of the bracket. Place one of the supplied washers onto each of the four mounting studs
on the EFIS-D6 and then slide the flush mount bracket over the EFIS-D6. The bracket should
wrap around the bezel of the EFIS-D6. Place one of the 4 supplied nuts on each of the 4 studs
and tighten the nuts. The EFIS-D6/bracket can now be installed from behind your panel using the
#6 screws through the previously drilled holes.
