Figs. 2-79 through 2-83 illustrate the available coil
arrangements. Contact Coil Marketing for other
arrangements not shown.
Face-split DX coils must be cong-
ured to provide full-face coverage
at all condensing unit load steps.
Johnson Controls assumes no re-
sponsibility for compressor failure
if full-face coverage is not applied.
Consult the factory, if application
assistance is needed to convert split
face to full-face operation.
