Instructions
• Line up the upper edge of the template with the existing
cutout. Use masking tape to secure the template to the
panel door. The dashed lines indicate the areas that must
be removed. To minimize the amount of cutting, it may be
desired to align the area to be removed with the upper left
corner of the existing cutout (as pictured)
• Using a center punch, mark the 12 mounting holes.

• Remove the template after making the center punch marks.
• Using a straight edge and marking pen draw a line starting
from the upper left hand corner of the existing cutout to the
center of H1 to H2 and H3.
• Use a #7 (.201) drill bit, drill all 12 mounting holes. M1 – M12
• Using the Zipcut disc or equivalent, start the cut from the
bottom left corner of the existing cutout and follow the
marked line to the center of H1. Continue the cut to H2
and H3. End the cut at the upper right hand corner of
the existing cutout.
• Deburr all cut edges before installing the new NGC-UIT2-HAZ.
