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 F
IG. 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.
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).
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.
