2. FOR CABLE WITH EXPOSED METAL BRAID (-C):
Push the braid back 12 inches on the cable. See Figure 2.
Figure 2
3. FOR ALL CABLE:
Feed the end of the cable through the appropriate hole in
the base. Allow 8 inches of cable to extend above the top of
the base. See Figure 3.
4. FOR ALL CABLE:
Slide cable grommet over the end of the cable and insert it into
the opening in the base. Attach the base to the pipe by threading
the appropriate sized pipestrap through the slot in the mounting
plate. Tighten the pipestrap until the base is loosely attached to
the pipe. See Figure 4.

5. FOR OVERCOATED CABLES (-CR or -CT):
Score the outer insulation 1-1/2 inches from the end of
the cable. Remove the jacket to expose the metal braid. See
Figure 5. WARNING: Do not damage the braid or the base
cable insulation.

6. FOR ALL CABLE:
Punch out the knockouts on the bottom of the box which cor-
respond to the openings in the base through which the heating
cable passes. For these kits, the openings to be knocked out
are the ones opposite the conduit entry and the one by the side
of the box. Be careful to punch out only those knockouts to be
used. If one is mistakenly punched, blank grommets can be
ordered to re-establish the watertight seal. See Figure 6.

and side hole of the base. Slip the grommet over the capillary
between the box and the base. See Figure 7.
Figure 6
8. FOR ALL CABLE:
Feed the cable through the end hole in the box. Allow 3/4 inch-
es of stainless steel capillary to extend above the bottom of the
box. Secure box to base using all four large (8-32) screws. See
Figure 8.
9. FOR OVERCOATED CABLE:
Starting from the end of the cable. unravel 1-1/2 inches of the
braid. Twist the strands together to form a pigtail. See Figure 9.
Figure 8
10. FOR SELF-REGULATING CABLE:
Using standard electrical cutters, cut a 3/4 inch long notch out
of the cable between the conductor wires. Bare a 3/8 inch
length of each conductor by stripping off the outside insula-
tion and the inner black core material. See Figure 10.
11. FOR CONSTANT WATTAGE CABLE:
Score the outer jacket 3/4 inch from the end of the cable and
remove the jacket. Cut off the exposed nichrome wire, pushing
any remainder back under the jacket. Constant Wattage cables
have an inner layer of insulation which is also to be removed
as described above. Separate the buss wires and strip off the
last 3/8 inch of insulation from both buss wires. See Figure 11.
