Bundle Individual Heated Hoses
Individual hoses must be bundled with a scuff guard, FTS cable(s), and air and signal cables.Follow the instructions below to bundle individual heated hoses for dual and single zone heat.
See FIG. 22 on page 29.
1.Lay out the A and B material hoses with the male fit- tings at the same end of the bundle.
2.Lay out the air hose (23) with the male fitting at the same end as the male fittings of the material hoses.
3.Lay out the signal cable (24) and FTS cable(s) (25) with the female end of the cables at the same end as the male fittings of the material hoses.
NOTE:
•All signal cable connectors (24) should be 2 in. (50.8 mm) beyond the male fittings of the mate- rial hoses.
•Use electrical tape (29) to secure position of sig- nal cable 10 in. (254 mm) back from the end of
the material hose.
4. Wrap FTS Cables.
NOTICE
To heat material correctly, ensure that the red electrical tape is on the A side FTS cable and the blue electrical tape is on B side FTS cable.
a.Wrap each end of one FTS cable (25) with red electrical tape (32). This FTS cable will corre- spond with the A material hose.
b.For Dual Zone Heat Only: wrap each end of the other FTS cable (25) with blue electrical tape (33). This FTS cable will correspond with the B material hose.
5.Carefully twist the material hoses, air hose (23), and cables throughout the entire bundle with a 24 in (609.6 mm) maximum pitch.
NOTE: Do not twist 5 ft and 10 ft hose bundle lengths.
6.Tightly wrap the bundle with lace (28) with an 8 in. maximum pitch. Use black electrical tape to stop the lacing 10 in. (254 mm) from the material fittings on each end of the hoses.
7.Use electrical tape and temporarily tape the hose and cable ends together.
8.Feed the scuff guard (26) over the female material hose fittings.
9.Use black electrical tape (29) and tape the scuff guard (26) down 10 in. from the female fittings on the material hoses. Tape at least 3 in. (76.2 mm) of scuff guard (26).
NOTE: Ensure no foam insulation is exposed on either material hose.
10.Fold the scuff guard (26) over itself and feed the remaining scuff guard over the entire length of the bundle.
11.Leave excess scuff guard (26) loose on the end with the male material fittings.
12.Remove electrical tape securing the hose and cable ends together.
13.Apply warning label (31) in the center of the bundle. Secure edges with black electrical tape (29).
