INSTALLATION SHOULD BE DONE IN THIS ORDER:
A. TIE DUCT OUTLET DUCT/OFFSET DUCT
B. MAIN HAB UNIT/FLEX DUCT
C. POINT NOZZLES AND TRACK DUCTS
D. ELECTRICAL
A. TIE DUCT
1.
Remove the appropriate tie. Choose the tie that will result in the point nozzles
being as close to the switch point as possible without interfering with normal
switch operation. The distance from the center of the tie duct to the end of the
point nozzles is 33”. If necessary, up to 10” may be cut off each point nozzle.
2.
Remove sufficient ballast to provide at least 14” clearance from the bottom of the
rails.
3.
Carefully slip the tie duct under the rails and position it so that the rails are
directly above the tie plates. Ensure that the tie duct is centered between the
adjacent ties.
4.
Place a rubber pad on the tie plate, then using a suitable lever, raise one end of the
tie duct until the rail lies correctly on the pad on the tie plate. Place two e-clip
insulators, one on each side of rail, in place and then fasten the rail to the tie plate
using two of the four 927248 rail clips. Use a heavy hammer or maul to drive the
clips securely into place.
5.
While keeping the tie duct supported in place, firmly pack ballast under the tie
duct from the rail out to the end.
6.
Repeat steps 4 and 5 for the other end of the tie duct.
7.
a. Remove the end flange plate nearest the HAB by loosening the six
retainer bolts.
b. Install the two-foot heavy duty offset duct (P/N 9278-3403) to the tie duct
using hardware and gasket supplied with the offset duct.
8.
Firmly repack ballast under the entire tie duct.
