Step 2 - Clean the abraded area of the furcation cable with a wipe dampened with alcohol and blow dry as necessary.
Step 3 - Thoroughly mix the two parts of the epoxy together and apply a small bead of the epoxy to the end face of the furcation cable to be sealed. (NOTE: The epoxy bead is applied to assure full sealing at the furcation cable end.)
Step 4 - Slide the end cap over the end of the furcation cable to be sealed.
Position the end cap to ensure that the furcation cable is fully
inserted into the end cap (see figure lEl-l).

Step 4 - CAUTION: Do not overheat the furcation cable. Prolonged exposure of the jacket to temperatures above l60oC (320oF) may damage the cable jacket. Discontinue heating of the sleeve and allow the cable jacket to cool before reheating, if the cable jacket shows any signs of bubbling.
Hold the heat gun approximately l00 mm (4 in) from the end cap and as heat is applied, move the heat gun back and forth over the end cap. Shrink the end cap from closed end to open end to avoid trapping air. (NOTE: Minimum recovery temperature is l2loC (250oF).
Step 5 - When the end cap has recovered enough to assume the configuration of the cable and excess adhesive appears at the end of the cap, discontinue heating (see figure lEl-2). (NOTE: Additional heat will not make end cap shrink more tightly.)
