Step 2: Cut overjackets back a distance of 3" (70 mm).
Kit Contents
(1) Splice/Tee, (1) End Termination
Step 3: Separate braids and twist into pig­tails. Carefully cut primary jackets back 2" (50 mm).
Splice and Tee Connection
Step 1: Allow 12" (30 cm) of extra length
for each heating cable at the connection point.
Step 4: Skive outer matrix material from conductors with utility knife.
Step 5: Peel exposed wires back from center matrix and cut center matrix away, leaving bare conductors.
Step 6: wrap black mastic around each cable beginning at a distance fo 1" (25 mm) back from the pigtail (overjacket).
Step 8: Stack the two (or three cables in the case of a tee) together and tighten down with two standard tie wraps at 8" (20 cm) and 10" (28 cm) respectively from the exposed bus wire end.
Step 7: Squeeze RTV into the silicone rubber boots and slide over cable ends.
Step 9: Twist all the pigtails together. Slide the large un-insulated lug over the braid ends in close proximity to the cables and then crimp. Trim off any extra braid. Bend pigtail back so that the crimp lug lies down.
INSTALLATION INSTRUCTIONS
Step 10: Wrap black electrical tape around
the cables and over the crimped lug.
Step 13: Slide the 8" (20 cm) heat shrink tube over the connection past the mastic approximately 1" (25 mm) and shrink from mastic end back toward the termi­nated splice end.
Step 11: Twist the bus wires of one side of the cables together and repeat with the other side, making sure that both wires from any one cable do not get twisted to­gether. Crimp insulating caps on each leg.
Step 14: Pinch heated shrink end with a pair of pliers until the encapsulant cools and seals.
Step 12: Wrap mastic tape around each terminated leg and insulation cap.
Step 15: Fold the splice back on itself to one of the outside cables and secure with a tie wrap. For roof and gutter applications secure the splice up and away from the bottom of the gutter.
End Termination . . .
Step 16: Cut back overjacket 0.5"
(12 mm).
Step 19: Slide the end cap on the end of the cable until fully seated.
Step 17: Trim ALL of the braid strands back to the overjacket with scissors.
Step 20: Put a small amount of RTV into the opening of the larger over-cap.
Step 18: Fill the smaller end cap with RTV.
Step 21: Slide
the over-cap over the end cap until fully seated.
