Wire Splicing; Power Supply Wire Installation - Master Pumps 123323 Manual Del Usuario

INSTALLATION
Splice wire to motor leads. Use only copper wire for connections to
pump motor and control box.
1. Taped splice (Wire Sizes No. 8 (7mm
A. Cut off motor leads. Stagger lead and wire length so that
2nd lead is 2" (50.8mm) longer than 1st lead and 3rd lead is 2"
(50.8mm) longer than second.
B. Cut off power supply wire ends. Match colors and lengths of
wires to colors and lengths of motor leads.
C. Trim insulation back 1/2" (12.7mm) from supply wire and motor
lead ends.
D. Insert motor lead ends and supply wire ends into butt
connectors (see Fig. 2). Match wire colors between supply
wires and motor leads.
E. Using crimping pliers, indent butt connector lugs (see Fig. 3) to
attach wires.
F. Cut "Scotchfil" electrical insulation putty into 3 equal parts
and form tightly around butt connectors. Be sure scotchfil
overlaps insulated part of wire.
G. Using #33 Scotch tape, wrap each joint tightly; cover wire for
about 1-1/2" (38.1mm) on each side of joint. Make four passes
with the tape. When finished you should have four layers of
tape tightly wrapped around the wire. Press edges of tape
firmly down against the wire (see Fig. 5).
NOTICE: Since tightly wound tape is the only means of keeping
water out of splice, efficiency of splice will depend on care
used in wrapping tape.
NOTICE: For wire sizes larger than No. 8 (7mm
joint rather than Scotchfil putty (see Fig. 4).
2. Heat shrink splice (For wire sizes #14, 12 and 10 AWG (2, 3 and
5mm ):

Completed splice
A. Remove 3/8" (9.5mm) insulation from ends of motor leads and
power supply wires.
B. Put plastic heat shrink tubing over motor leads between power
supply and motor.
C. Match wire colors and lengths between power supply and
motor.
D. Insert supply wire and lead ends into butt connector and crimp
(See Figs. 2 and 3). Match wire colors between power supply
and motor. Pull leads to check connections.
E. Center tubing over butt connector and apply heat evenly with
torch (match or lighter will not supply enough heat).
NOTICE: Keep torch moving. Too much concentrated heat may
damage tubing (see Fig. 6).

A. Cut off motor leads. Stagger lead and wire length so that
2nd lead is 4" (101.6mm) longer than 1st lead and 3rd lead is 4"
(101.6mm) longer than second.

B. Cut off wire ends. Match colors and lengths of wires between
power supply and motor.
C. Trim insulation back 1/2" (12.7mm) from power supply wire and
motor lead ends.
D. Unscrew plastic caps from insulators. Place a cap and
neoprene gasket sleeve on each wire to be spliced (see Fig.
7).
E. Slide insulator body onto one wire end (Fig. 7).
F. Insert wire end into butt connector and crimp. Match wire
colors between power supply and motor (see Fig. 8).
G. Center insulator body over splice and slide gasket sleeves into
body as far as they will go. Screw caps onto insulator body
(Fig. 9) and tighten by hand for a strong, waterproof splice.

POWER SUPPLY WIRE INSTALLATION

1. To test submersible, momentarily (no more than 30 seconds)
connect it to proper power supply. Power supply frequency and
voltage must match motor nameplate frequency and voltage to
within ±10%.
2. Fasten the power supply wire leads securely to the pump
discharge. Fasten the splices to the discharge pipe, as close to
the pump discharge as is practical. Install the torque arrestor
around the splices if possible (this protects the splices from
chafing). Make sure that the splices are protected from any pulling
strain on the wire leads. Use the centering guides to protect the
wire and pipe from rubbing on the well casing.
3. Connect copper ground wire to motor bracket. Ground wire
must be as large as wires supplying current to motor. Consult
current Canadian Electrical Code and local codes for grounding
information.
