TM5-3820-256-10 (1) Cut the motor lead and power cable so that ends will butt squarely. Thoroughly clean the cable jacket for 4 inches beyond dimension A (see detail A) with non-conductive abrasive cloth provided in the cable splicing kit. (2) Remove the cable jackets for dimension A (see detail B), plus one half the connector length. DO NOT cut into cable insulation. If jacket is bonded to insulation, do not remove; treat it as insulation. Remove cable insulation and strand shielding from end of conductors for 1/2inch plus one-half the length of the connector. DO NOT nick conductor. (3) Pencil-taper the insulation for dimension B(see detail C) and smooth it with abrasive cloth provided in cable splice kit. (4) Join the conductors using crimp connector (see detail D). Using cloth saturated with solvent in the splice kit, clean entire splice area. CAUTION The splice area must be entirely free of all solvent residue (especially in conductor strands) before applying any tape. (5) Fill any connector indents with small pieces of semi-conducting tape. Tightly level-wind tape across connection area, overlapping 1/16-inch onto each edge of the tapered insulation. Form smooth, concentric buildup as shown in detail D. (6) Tightly, half-lap tape across connector area, building up to dimension D (see detail E) with a smooth taper along distance C, reaching maximum diameter over the tapered insulation. NOTE Stretch and half-lap the tape to produce a void-free, uniform buildup. (7) Tightly, half lap two layers of vinyl plastic electrical tape over the entire splice, extending for one inch onto each cable jacket. c. Inserting Pump Into Well. (1) Attach the power cable to the submersible pump using the cable guard and cable clamp (see figure 2- 48). (2) Position the pump and motor over the hole and slowly lower the pump into the hole until hose elevator clamp is resting atop the casing. (3) Install the well-head roller above the well with the hose positioned over the roller (see figure 2-50). 2-115
