10. If CCH (coil connection housing) is installed at a section
split:
a. Use the Intelliclamp connectors on the vertical
frames and the split brackets on the top frames to
bring the sections together.
b. Remove the upstream side panels to gain access to
the inner surface of the frames.
c. Use tool clearance holes to install ¼-in. screws into
the downstream frame for the permanent section
joint (only necessary on the CCH side). Detail D in
Fig. 25 shows the location of the holes; the number
of holes will vary by unit.
d. Reinstall upstream access panel.
e. Remove the Intelliclamp connectors, the split sec-
tion L bracket, and the lifting lug under the section
that match the CCH side walls and install the CCH
as described in Coil Connection Housing section
on page 110.
11. Where fan is blow-thru airfoil or forward-curved, install
fan discharge diffuser to bulkhead.
WARNING
