INSTALLATION
Wire Splicing
Splice wire to motor leads using only copper wire for
connections to pump motor and control box.
1. Tapered splice (Wire sizes No. 8 and larger):
A. Cut motor lead staggering lead and wire length
so that second lead is 2” longer than first lead and
third lead is 2” longer than second.
B. Cut off power supply wire ends. Match colors and
lengths of the wires to colors and lengths of motor
leads.
C. Trim installation back 1/2” from supply wire and
motor lead ends.
D. Insert motor lead ends and supply wire ends into
butt connectors. Match wire colors between supply
wires and motor leads.
E. Using crimping pliers, indent butt connector lugs to
attach
wire.
F. Cut electrical “Scotchfil™” or equivalent insulation
putty into three equal parts and form tightly around
butt connectors. Be sure Scotchfil™ overlaps
insulted part of wire.
G. Using #33 Scotch™ or equivalent tape, wrap each
joint tightly; cover wire for about 1-1/2” 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.
NOTICE: Since tightly wound tape is the only
means of keeping water out of splice, efficiency of
splice will depend on the care used in wrapping the
tape.
NOTICE: For wire sizes larger than No. 8, use
soldered joint rather than Scotchfil™ putty.
2. Heat shrink splice
[for wire sizes #14, 12 and AWG (2,3 and 5mm)]
A. Remove 3/8” 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. 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 concen-
trated heat may damage tubing.
3. Mechanical Splice Kit with plastic insulators (for 14, 12
and 10 Gauge AWG Wire (2, 3 and 5mm):
A. Cut motor leads staggering 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 wire ends matching 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.
E. Slide insulator body onto one wire end.
F. Insert wire end into butt connector and crimp.
Match wire colors between power supply and motor
G. Center insulator body over splice and slide gasket
sleeves into body as far as they will go. Screw caps
onto insulator body and tighten by hand for a strong,
waterproof splice.
Power Supply Wire Installation
1. To test submersible, momentarily (no more than 5
seconds) connect it to proper power supply. Power
supply frequency and voltage must match motor name
plate frequency and voltage to within ±10%.
2. Fasten power supply wire leads securely to pump
discharge section; leave 4-5” (100-125mm) of slack in
leads at this point. Securely fasten leads to plastic pipe
within 6” (150mm) of the pump discharge section. Use
centering guides to protect wire and pipe from rubbing
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.
4. Most 4” pumps have an eyelet on the pumps discharge
for attaching a rope to assist in lowering into and
pulling the pump from the well. Attach a nylon rope of
adequate length to eyelet
5. Do not use submersible power supply wires supplied
by pump manufacturer to lower or lift pump. When
lowering pump into well use only the rope and/or
discharge pipe, secure supply wires to discharge pipe
at 10 ft. (3M) intervals with Scotch™ #33 or equivalent
electrical tape. DO NOT damage pump wires.
NOTICE:
To avoid dropping pump down well or damaging wires
or splices, NEVER allow pump wires to support weight
of pump.
